This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC5981 - Authorization for NSIS Signaling Layer Protocols
Signaling layer protocols specified within the Next Steps in Signaling (NSIS) framework may rely on the General Internet Signaling Transport (GIST) protocol to handle authorization. Still, the signaling layer protocol above GIST itself may require separate authorization to be performed when a node receives a request for a certain kind of service or resources. This document presents a generic model and object formats for session authorization within the NSIS signaling layer protocols. The goal of session authorization is to allow the exchange of information between network elements in order to authorize the use of resources for a service and to coordinate actions between the signaling and transport planes. This document defines an Experimental Protocol for the Internet community.
RFC5980 - NSIS Protocol Operation in Mobile Environments
Mobility of an IP-based node affects routing paths, and as a result, can have a significant effect on the protocol operation and state management. This document discusses the effects mobility can cause to the Next Steps in Signaling (NSIS) protocol suite, and shows how the NSIS protocols operate in different scenarios with mobility management protocols. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC5979 - NSIS Operation over IP Tunnels
NSIS Quality of Service (QoS) signaling enables applications to perform QoS reservation along a data flow path. When the data flow path contains IP tunnel segments, NSIS QoS signaling has no effect within those tunnel segments. Therefore, the resulting tunnel segments could become the weakest QoS link and invalidate the QoS efforts in the rest of the end-to-end path. The problem with NSIS signaling within the tunnel is caused by the tunnel encapsulation that masks packets' original IP header fields. Those original IP header fields are needed to intercept NSIS signaling messages and classify QoS data packets. This document defines a solution to this problem by mapping end-to-end QoS session requests to corresponding QoS sessions in the tunnel, thus extending the end-to-end QoS signaling into the IP tunnel segments. This document defines an Experimental Protocol for the Internet community.
RFC5978 - Using and Extending the NSIS Protocol Family
This document gives an overview of the Next Steps in Signaling (NSIS) framework and protocol suite created by the NSIS Working Group during the period of 2001-2010. It also includes suggestions on how the industry can make use of the new protocols and how the community can exploit the extensibility of both the framework and existing protocols to address future signaling needs. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC5977 - RMD-QOSM: The NSIS Quality-of-Service Model for Resource Management in Diffserv
This document describes a Next Steps in Signaling (NSIS) Quality-of-Service (QoS) Model for networks that use the Resource Management in Diffserv (RMD) concept. RMD is a technique for adding admission control and preemption function to Differentiated Services (Diffserv) networks. The RMD QoS Model allows devices external to the RMD network to signal reservation requests to Edge nodes in the RMD network. The RMD Ingress Edge nodes classify the incoming flows into traffic classes and signals resource requests for the corresponding traffic class along the data path to the Egress Edge nodes for each flow. Egress nodes reconstitute the original requests and continue forwarding them along the data path towards the final destination. In addition, RMD defines notification functions to indicate overload situations within the domain to the Edge nodes. This document defines an Experimental Protocol for the Internet community.
RFC5976 - Y.1541-QOSM: Model for Networks Using Y.1541 Quality-of-Service Classes
This document describes a QoS-NSLP Quality-of-Service model (QOSM) based on ITU-T Recommendation Y.1541 Network QoS Classes and related guidance on signaling. Y.1541 specifies 8 classes of Network Performance objectives, and the Y.1541-QOSM extensions include additional QSPEC parameters and QOSM processing guidelines. This document defines an Experimental Protocol for the Internet community.
RFC5975 - QSPEC Template for the Quality-of-Service NSIS Signaling Layer Protocol (NSLP)
The Quality-of-Service (QoS) NSIS signaling layer protocol (NSLP) is used to signal QoS reservations and is independent of a specific QoS model (QOSM) such as IntServ or Diffserv. Rather, all information specific to a QOSM is encapsulated in a separate object, the QSPEC. This document defines a template for the QSPEC including a number of QSPEC parameters. The QSPEC parameters provide a common language to be reused in several QOSMs and thereby aim to ensure the extensibility and interoperability of QoS NSLP. While the base protocol is QOSM-agnostic, the parameters that can be carried in the QSPEC object are possibly closely coupled to specific models. The node initiating the NSIS signaling adds an Initiator QSPEC, which indicates the QSPEC parameters that must be interpreted by the downstream nodes less the reservation fails, thereby ensuring the intention of the NSIS initiator is preserved along the signaling path. This document defines an Experimental Protocol for the Internet community.
RFC5974 - NSIS Signaling Layer Protocol (NSLP) for Quality-of-Service Signaling
This specification describes the NSIS Signaling Layer Protocol (NSLP) for signaling Quality of Service (QoS) reservations in the Internet. It is in accordance with the framework and requirements developed in NSIS. Together with General Internet Signaling Transport (GIST), it provides functionality similar to RSVP and extends it. The QoS NSLP is independent of the underlying QoS specification or architecture and provides support for different reservation models. It is simplified by the elimination of support for multicast flows. This specification explains the overall protocol approach, describes the design decisions made, and provides examples. It specifies object, message formats, and processing rules. This document defines an Experimental Protocol for the Internet community.
RFC5973 - NAT/Firewall NSIS Signaling Layer Protocol (NSLP)
This memo defines the NSIS Signaling Layer Protocol (NSLP) for Network Address Translators (NATs) and firewalls. This NSLP allows hosts to signal on the data path for NATs and firewalls to be configured according to the needs of the application data flows. For instance, it enables hosts behind NATs to obtain a publicly reachable address and hosts behind firewalls to receive data traffic. The overall architecture is given by the framework and requirements defined by the Next Steps in Signaling (NSIS) working group. The network scenarios, the protocol itself, and examples for path-coupled signaling are given in this memo. This document defines an Experimental Protocol for the Internet community.
RFC5971 - GIST: General Internet Signalling Transport
This document specifies protocol stacks for the routing and transport of per-flow signalling messages along the path taken by that flow through the network. The design uses existing transport and security protocols under a common messaging layer, the General Internet Signalling Transport (GIST), which provides a common service for diverse signalling applications. GIST does not handle signalling application state itself, but manages its own internal state and the configuration of the underlying transport and security protocols to enable the transfer of messages in both directions along the flow path. The combination of GIST and the lower layer transport and security protocols provides a solution for the base protocol component of the "Next Steps in Signalling" (NSIS) framework. This document defines an Experimental Protocol for the Internet community.
RFC5970 - DHCPv6 Options for Network Boot

RFC5969 - IPv6 Rapid Deployment on IPv4 Infrastructures (6rd) -- Protocol Specification
This document specifies an automatic tunneling mechanism tailored to advance deployment of IPv6 to end users via a service provider's IPv4 network infrastructure. Key aspects include automatic IPv6 prefix delegation to sites, stateless operation, simple provisioning, and service, which is equivalent to native IPv6 at the sites that are served by the mechanism. [STANDARDS-TRACK]
RFC5968 - Guidelines for Extending the RTP Control Protocol (RTCP)
The RTP Control Protocol (RTCP) is used along with the Real-time Transport Protocol (RTP) to provide a control channel between media senders and receivers. This allows constructing a feedback loop to enable application adaptation and monitoring, among other uses. The basic reporting mechanisms offered by RTCP are generic, yet quite powerful and suffice to cover a range of uses. This document provides guidelines on extending RTCP if those basic mechanisms prove insufficient. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC5967 - The application/pkcs10 Media Type
This document specifies a media type used to carry PKCS #10 certification requests as defined in RFC 2986.

RFC5963 - IPv6 Deployment in Internet Exchange Points (IXPs)
This document provides guidance on IPv6 deployment in Internet Exchange Points (IXPs). It includes information regarding the switch fabric configuration, the addressing plan and general organizational tasks that need to be performed. IXPs are mainly a Layer 2 infrastructure, and, in many cases, the best recommendations suggest that the IPv6 data, control, and management plane should not be handled differently than in IPv4. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC5962 - Dynamic Extensions to the Presence Information Data Format Location Object (PIDF-LO)

This document defines PIDF-LO extensions to convey information about moving objects. Elements are defined that enable expression of spatial orientation, speed, and heading of the presentity. [STANDARDS TRACK]
RFC5961 - Improving TCP's Robustness to Blind In-Window Attacks
TCP has historically been considered to be protected against spoofed off-path packet injection attacks by relying on the fact that it is difficult to guess the 4-tuple (the source and destination IP addresses and the source and destination ports) in combination with the 32-bit sequence number(s). A combination of increasing window sizes and applications using longer-term connections (e.g., H-323 or Border Gateway Protocol (BGP) [STANDARDS-TRACK]
RFC5960 - MPLS Transport Profile Data Plane Architecture

RFC5987 - Character Set and Language Encoding for Hypertext Transfer Protocol (HTTP) Header Field Parameters
By default, message header field parameters in Hypertext Transfer Protocol (HTTP) messages cannot carry characters outside the ISO- 8859-1 character set. RFC 2231 defines an encoding mechanism for use in Multipurpose Internet Mail Extensions (MIME) headers. This document specifies an encoding suitable for use in HTTP header fields that is compatible with a profile of the encoding defined in RFC 2231. [STANDARDS-TRACK]
RFC5986 - Discovering the Local Location Information Server (LIS)
Discovery of the correct Location Information Server (LIS) in the local access network is necessary for Devices that wish to acquire location information from the network. A method is described for the discovery of a LIS in the access network serving a Device. Dynamic Host Configuration Protocol (DHCP) options for IP versions 4 and 6 are defined that specify a domain name. This domain name is then used as input to a URI-enabled NAPTR (U-NAPTR) resolution process. [STANDARDS-TRACK]
RFC5985 - HTTP-Enabled Location Delivery (HELD)

RFC5982 - IP Flow Information Export (IPFIX) Mediation: Problem Statement
Flow-based measurement is a popular method for various network monitoring usages. The sharing of flow-based information for monitoring applications having different requirements raises some open issues in terms of measurement system scalability, flow-based measurement flexibility, and export reliability that IP Flow Information Export (IPFIX) Mediation may help resolve. This document describes some problems related to flow-based measurement that network administrators have been facing, and then it describes IPFIX Mediation applicability examples along with the problems. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC5981 - Authorization for NSIS Signaling Layer Protocols
Signaling layer protocols specified within the Next Steps in Signaling (NSIS) framework may rely on the General Internet Signaling Transport (GIST) protocol to handle authorization. Still, the signaling layer protocol above GIST itself may require separate authorization to be performed when a node receives a request for a certain kind of service or resources. This document presents a generic model and object formats for session authorization within the NSIS signaling layer protocols. The goal of session authorization is to allow the exchange of information between network elements in order to authorize the use of resources for a service and to coordinate actions between the signaling and transport planes. This document defines an Experimental Protocol for the Internet community.
RFC5980 - NSIS Protocol Operation in Mobile Environments
Mobility of an IP-based node affects routing paths, and as a result, can have a significant effect on the protocol operation and state management. This document discusses the effects mobility can cause to the Next Steps in Signaling (NSIS) protocol suite, and shows how the NSIS protocols operate in different scenarios with mobility management protocols. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC5979 - NSIS Operation over IP Tunnels
NSIS Quality of Service (QoS) signaling enables applications to perform QoS reservation along a data flow path. When the data flow path contains IP tunnel segments, NSIS QoS signaling has no effect within those tunnel segments. Therefore, the resulting tunnel segments could become the weakest QoS link and invalidate the QoS efforts in the rest of the end-to-end path. The problem with NSIS signaling within the tunnel is caused by the tunnel encapsulation that masks packets' original IP header fields. Those original IP header fields are needed to intercept NSIS signaling messages and classify QoS data packets. This document defines a solution to this problem by mapping end-to-end QoS session requests to corresponding QoS sessions in the tunnel, thus extending the end-to-end QoS signaling into the IP tunnel segments. This document defines an Experimental Protocol for the Internet community.
RFC5978 - Using and Extending the NSIS Protocol Family
This document gives an overview of the Next Steps in Signaling (NSIS) framework and protocol suite created by the NSIS Working Group during the period of 2001-2010. It also includes suggestions on how the industry can make use of the new protocols and how the community can exploit the extensibility of both the framework and existing protocols to address future signaling needs. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC5977 - RMD-QOSM: The NSIS Quality-of-Service Model for Resource Management in Diffserv
This document describes a Next Steps in Signaling (NSIS) Quality-of-Service (QoS) Model for networks that use the Resource Management in Diffserv (RMD) concept. RMD is a technique for adding admission control and preemption function to Differentiated Services (Diffserv) networks. The RMD QoS Model allows devices external to the RMD network to signal reservation requests to Edge nodes in the RMD network. The RMD Ingress Edge nodes classify the incoming flows into traffic classes and signals resource requests for the corresponding traffic class along the data path to the Egress Edge nodes for each flow. Egress nodes reconstitute the original requests and continue forwarding them along the data path towards the final destination. In addition, RMD defines notification functions to indicate overload situations within the domain to the Edge nodes. This document defines an Experimental Protocol for the Internet community.
RFC5976 - Y.1541-QOSM: Model for Networks Using Y.1541 Quality-of-Service Classes
This document describes a QoS-NSLP Quality-of-Service model (QOSM) based on ITU-T Recommendation Y.1541 Network QoS Classes and related guidance on signaling. Y.1541 specifies 8 classes of Network Performance objectives, and the Y.1541-QOSM extensions include additional QSPEC parameters and QOSM processing guidelines. This document defines an Experimental Protocol for the Internet community.
RFC5975 - QSPEC Template for the Quality-of-Service NSIS Signaling Layer Protocol (NSLP)
The Quality-of-Service (QoS) NSIS signaling layer protocol (NSLP) is used to signal QoS reservations and is independent of a specific QoS model (QOSM) such as IntServ or Diffserv. Rather, all information specific to a QOSM is encapsulated in a separate object, the QSPEC. This document defines a template for the QSPEC including a number of QSPEC parameters. The QSPEC parameters provide a common language to be reused in several QOSMs and thereby aim to ensure the extensibility and interoperability of QoS NSLP. While the base protocol is QOSM-agnostic, the parameters that can be carried in the QSPEC object are possibly closely coupled to specific models. The node initiating the NSIS signaling adds an Initiator QSPEC, which indicates the QSPEC parameters that must be interpreted by the downstream nodes less the reservation fails, thereby ensuring the intention of the NSIS initiator is preserved along the signaling path. This document defines an Experimental Protocol for the Internet community.
RFC5974 - NSIS Signaling Layer Protocol (NSLP) for Quality-of-Service Signaling
This specification describes the NSIS Signaling Layer Protocol (NSLP) for signaling Quality of Service (QoS) reservations in the Internet. It is in accordance with the framework and requirements developed in NSIS. Together with General Internet Signaling Transport (GIST), it provides functionality similar to RSVP and extends it. The QoS NSLP is independent of the underlying QoS specification or architecture and provides support for different reservation models. It is simplified by the elimination of support for multicast flows. This specification explains the overall protocol approach, describes the design decisions made, and provides examples. It specifies object, message formats, and processing rules. This document defines an Experimental Protocol for the Internet community.
RFC5973 - NAT/Firewall NSIS Signaling Layer Protocol (NSLP)
This memo defines the NSIS Signaling Layer Protocol (NSLP) for Network Address Translators (NATs) and firewalls. This NSLP allows hosts to signal on the data path for NATs and firewalls to be configured according to the needs of the application data flows. For instance, it enables hosts behind NATs to obtain a publicly reachable address and hosts behind firewalls to receive data traffic. The overall architecture is given by the framework and requirements defined by the Next Steps in Signaling (NSIS) working group. The network scenarios, the protocol itself, and examples for path-coupled signaling are given in this memo. This document defines an Experimental Protocol for the Internet community.
RFC5971 - GIST: General Internet Signalling Transport
This document specifies protocol stacks for the routing and transport of per-flow signalling messages along the path taken by that flow through the network. The design uses existing transport and security protocols under a common messaging layer, the General Internet Signalling Transport (GIST), which provides a common service for diverse signalling applications. GIST does not handle signalling application state itself, but manages its own internal state and the configuration of the underlying transport and security protocols to enable the transfer of messages in both directions along the flow path. The combination of GIST and the lower layer transport and security protocols provides a solution for the base protocol component of the "Next Steps in Signalling" (NSIS) framework. This document defines an Experimental Protocol for the Internet community.
RFC5970 - DHCPv6 Options for Network Boot

RFC5968 - Guidelines for Extending the RTP Control Protocol (RTCP)
The RTP Control Protocol (RTCP) is used along with the Real-time Transport Protocol (RTP) to provide a control channel between media senders and receivers. This allows constructing a feedback loop to enable application adaptation and monitoring, among other uses. The basic reporting mechanisms offered by RTCP are generic, yet quite powerful and suffice to cover a range of uses. This document provides guidelines on extending RTCP if those basic mechanisms prove insufficient.
