RFC5444 - Generalized Mobile Ad Hoc Network (MANET) Packet/Message Format
This document specifies a packet format capable of carrying multiple messages that may be used by mobile ad hoc network routing protocols. [STANDARDS-TRACK]
RFC5443 - LDP IGP Synchronization
In certain networks, there is dependency on the edge-to-edge Label Switched Paths (LSPs) setup by the Label Distribution Protocol (LDP), e.g., networks that are used for Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) applications. For such applications, it is not possible to rely on Internet Protocol (IP) forwarding if the MPLS LSP is not operating appropriately. Blackholing of labeled traffic can occur in situations where the Interior Gateway Protocol (IGP) is operational on a link on which LDP is not. While the link could still be used for IP forwarding, it is not useful for MPLS forwarding, for example, MPLS VPN applications or Border Gateway Protocol (BGP) route-free cores. This document describes a mechanism to avoid traffic loss due to this condition without introducing any protocol changes. This memo provides information for the Internet community.

RFC5441 - A Backward-Recursive PCE-Based Computation (BRPC) Procedure to Compute Shortest Constrained Inter-Domain Traffic Engineering Label Switched Paths
The ability to compute shortest constrained Traffic Engineering Label Switched Paths (TE LSPs) in Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks across multiple domains has been identified as a key requirement. In this context, a domain is a collection of network elements within a common sphere of address management or path computational responsibility such as an IGP area or an Autonomous Systems. This document specifies a procedure relying on the use of multiple Path Computation Elements (PCEs) to compute such inter-domain shortest constrained paths across a predetermined sequence of domains, using a backward-recursive path computation technique. This technique preserves confidentiality across domains, which is sometimes required when domains are managed by different service providers. [STANDARDS-TRACK]
RFC5440 - Path Computation Element (PCE) Communication Protocol (PCEP)
This document specifies the Path Computation Element (PCE) Communication Protocol (PCEP) for communications between a Path Computation Client (PCC) and a PCE, or between two PCEs. Such interactions include path computation requests and path computation replies as well as notifications of specific states related to the use of a PCE in the context of Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering. PCEP is designed to be flexible and extensible so as to easily allow for the addition of further messages and objects, should further requirements be expressed in the future. [STANDARDS-TRACK]
RFC5439 - An Analysis of Scaling Issues in MPLS-TE Core Networks
Traffic engineered Multiprotocol Label Switching (MPLS-TE) is deployed in providers' core networks. As providers plan to grow these networks, they need to understand whether existing protocols and implementations can support the network sizes that they are planning.

RFC5424 - The Syslog Protocol
This document describes the syslog protocol, which is used to convey event notification messages. This protocol utilizes a layered architecture, which allows the use of any number of transport protocols for transmission of syslog messages. It also provides a message format that allows vendor-specific extensions to be provided in a structured way.
RFC5423 - Internet Message Store Events
One of the missing features in the existing Internet mail and messaging standards is a facility for server-to-server and server-to- client event notifications related to message store events. As the scope of Internet mail expands to support more diverse media (such as voice mail) and devices (such as cell phones) and to provide rich interactions with other services (such as web portals and legal compliance systems), the need for an interoperable notification system increases. This document attempts to enumerate the types of events that interest real-world consumers of such a system.
RFC5422 - Dynamic Provisioning Using Flexible Authentication via Secure Tunneling Extensible Authentication Protocol (EAP-FAST)
The Flexible Authentication via Secure Tunneling Extensible Authentication Protocol (EAP-FAST) method enables secure communication between a peer and a server by using Transport Layer Security (TLS) to establish a mutually authenticated tunnel.

This protocol includes an object (the SESSION_ATTRIBUTE object) that carries a Flags field used to indicate options and attributes of the LSP. That Flags field has eight bits, allowing for eight options to be set. Recent proposals in many documents that extend RSVP-TE have suggested uses for each of the previously unused bits.
RFC5419 - Why the Authentication Data Suboption is Needed for Mobile IPv6 (MIPv6)
Mobile IPv6 defines a set of signaling messages that enable the mobile node (MN) to authenticate and perform registration with its home agent (HA). These authentication signaling messages between the mobile node and home agent are secured by an IPsec security association (SA) that is established between the MN and HA. The MIP6 working group has specified a mechanism to secure the Binding Update (BU) and Binding Acknowledgement (BAck) messages using an authentication option, similar to the authentication option in Mobile IPv4, carried within the signaling messages that are exchanged between the MN and HA to establish a binding. This document provides the justifications as to why the authentication option mechanism is needed for Mobile IPv6 deployment in certain environments. This memo provides information for the Internet community.
RFC5418 - Control And Provisioning of Wireless Access Points (CAPWAP) Threat Analysis for IEEE 802.11 Deployments
Early Wireless Local Area Network (WLAN) deployments feature a "fat" Access Point (AP), which serves as a \%stand-alone interface between the wired and wireless network segments. However, this model raises scaling, mobility, and manageability issues, and the Control and Provisioning of Wireless Access Points (CAPWAP) protocol is meant to address these issues. CAPWAP effectively splits the fat AP functionality into two network elements, and the communication channel between these components may traverse potentially hostile hops. This document analyzes the security exposure resulting from the introduction of CAPWAP and summarizes the associated security considerations for IEEE 802.11-based CAPWAP implementations and deployments. This memo provides information for the Internet community.
RFC5417 - Control And Provisioning of Wireless Access Points (CAPWAP) Access Controller DHCP Option

RFC5416 - Control and Provisioning of Wireless Access Points (CAPWAP) Protocol Binding for IEEE 802.11
Wireless LAN product architectures have evolved from single autonomous access points to systems consisting of a centralized Access Controller (AC) and Wireless Termination Points (WTPs). The general goal of centralized control architectures is to move access control, including user authentication and authorization, mobility management, and radio management from the single access point to a centralized controller.
RFC5415 - Control And Provisioning of Wireless Access Points (CAPWAP) Protocol Specification
This specification defines the Control And Provisioning of Wireless Access Points (CAPWAP) Protocol, meeting the objectives defined by the CAPWAP Working Group in RFC 4564.

This document describes the base CAPWAP protocol, while separate binding extensions will enable its use with additional wireless technologies. [STANDARDS-TRACK]
RFC5414 - Wireless LAN Control Protocol (WiCoP)
The popularity of wireless local area networks (WLANs) has led to widespread deployments across different establishments. It has also translated into an increasing scale of the WLANs. Large-scale deployments made of large numbers of wireless termination points (WTPs) and covering substantial areas are increasingly common.
RFC5413 - SLAPP: Secure Light Access Point Protocol
The Control and Provisioning of Wireless Access Points (CAPWAP) problem statement describes a problem that needs to be addressed before a wireless LAN (WLAN) network designer can construct a solution composed of Wireless Termination Points (WTP) and Access Controllers (AC) from multiple, different vendors. One of the primary goals is to find a solution that solves the interoperability between the two classes of devices (WTPs and ACs) that then enables an AC from one vendor to control and manage a WTP from another.
RFC5412 - Lightweight Access Point Protocol
In recent years, there has been a shift in wireless LAN (WLAN) product architectures from autonomous access points to centralized control of lightweight access points. The general goal has been to move most of the traditional wireless functionality such as access control (user authentication and authorization), mobility, and radio management out of the access point into a centralized controller.
RFC5411 - A Hitchhiker's Guide to the Session Initiation Protocol (SIP)
The Session Initiation Protocol (SIP) is the subject of numerous specifications that have been produced by the IETF.

This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC5406 - Guidelines for Specifying the Use of IPsec Version 2
The Security Considerations sections of many Internet Drafts say, in effect, "just use IPsec". While this is sometimes correct, more often it will leave users without real, interoperable security mechanisms. This memo offers some guidance on when IPsec Version 2 should and should not be specified. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC5405 - Unicast UDP Usage Guidelines for Application Designers
The User Datagram Protocol (UDP) provides a minimal message-passing transport that has no inherent congestion control mechanisms. Because congestion control is critical to the stable operation of the Internet, applications and upper-layer protocols that choose to use UDP as an Internet transport must employ mechanisms to prevent congestion collapse and to establish some degree of fairness with concurrent traffic. This document provides guidelines on the use of UDP for the designers of unicast applications and upper-layer protocols. Congestion control guidelines are a primary focus, but the document also provides guidance on other topics, including message sizes, reliability, checksums, and middlebox traversal. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC5404 - RTP Payload Format for G.719

The MIP6 working group has specified a mechanism to secure the Binding Update (BU) and Binding Acknowledgement (BAck) messages using an authentication option, similar to the authentication option in Mobile IPv4, carried within the signaling messages that are exchanged between the MN and HA to establish a binding. This document provides the justifications as to why the authentication option mechanism is needed for Mobile IPv6 deployment in certain environments.

RFC5418 - Control And Provisioning of Wireless Access Points (CAPWAP) Threat Analysis for IEEE 802.11 Deployments
Early Wireless Local Area Network (WLAN) deployments feature a "fat" Access Point (AP), which serves as a \%stand-alone interface between the wired and wireless network segments. However, this model raises scaling, mobility, and manageability issues, and the Control and Provisioning of Wireless Access Points (CAPWAP) protocol is meant to address these issues. CAPWAP effectively splits the fat AP functionality into two network elements, and the communication channel between these components may traverse potentially hostile hops. This document analyzes the security exposure resulting from the introduction of CAPWAP and summarizes the associated security considerations for IEEE 802.11-based CAPWAP implementations and deployments. This memo provides information for the Internet community.
RFC5417 - Control And Provisioning of Wireless Access Points (CAPWAP) Access Controller DHCP Option

RFC5416 - Control and Provisioning of Wireless Access Points (CAPWAP) Protocol Binding for IEEE 802.11
Wireless LAN product architectures have evolved from single autonomous access points to systems consisting of a centralized Access Controller (AC) and Wireless Termination Points (WTPs). The general goal of centralized control architectures is to move access control, including user authentication and authorization, mobility management, and radio management from the single access point to a centralized controller.
RFC5415 - Control And Provisioning of Wireless Access Points (CAPWAP) Protocol Specification
This specification defines the Control And Provisioning of Wireless Access Points (CAPWAP) Protocol, meeting the objectives defined by the CAPWAP Working Group in RFC 4564. The CAPWAP protocol is designed to be flexible, allowing it to be used for a variety of wireless technologies. This document describes the base CAPWAP protocol, while separate binding extensions will enable its use with additional wireless technologies. [STANDARDS-TRACK]
RFC5414 - Wireless LAN Control Protocol (WiCoP)
The popularity of wireless local area networks (WLANs) has led to widespread deployments across different establishments. It has also translated into an increasing scale of the WLANs. Large-scale deployments made of large numbers of wireless termination points (WTPs) and covering substantial areas are increasingly common.
RFC5413 - SLAPP: Secure Light Access Point Protocol
The Control and Provisioning of Wireless Access Points (CAPWAP) problem statement describes a problem that needs to be addressed before a wireless LAN (WLAN) network designer can construct a solution composed of Wireless Termination Points (WTP) and Access Controllers (AC) from multiple, different vendors. One of the primary goals is to find a solution that solves the interoperability between the two classes of devices (WTPs and ACs) that then enables an AC from one vendor to control and manage a WTP from another.
RFC5412 - Lightweight Access Point Protocol
In recent years, there has been a shift in wireless LAN (WLAN) product architectures from autonomous access points to centralized control of lightweight access points. The general goal has been to move most of the traditional wireless functionality such as access control (user authentication and authorization), mobility, and radio management out of the access point into a centralized controller.
RFC5411 - A Hitchhiker's Guide to the Session Initiation Protocol (SIP)

RFC5406 - Guidelines for Specifying the Use of IPsec Version 2
The Security Considerations sections of many Internet Drafts say, in effect, "just use IPsec". While this is sometimes correct, more often it will leave users without real, interoperable security mechanisms. This memo offers some guidance on when IPsec Version 2 should and should not be specified. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC5405 - Unicast UDP Usage Guidelines for Application Designers
The User Datagram Protocol (UDP) provides a minimal message-passing transport that has no inherent congestion control mechanisms. Because congestion control is critical to the stable operation of the Internet, applications and upper-layer protocols that choose to use UDP as an Internet transport must employ mechanisms to prevent congestion collapse and to establish some degree of fairness with concurrent traffic. This document provides guidelines on the use of UDP for the designers of unicast applications and upper-layer protocols. Congestion control guidelines are a primary focus, but the document also provides guidance on other topics, including message sizes, reliability, checksums, and middlebox traversal. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
RFC5404 - RTP Payload Format for G.719
