RFC6356 - Coupled Congestion Control for Multipath Transport Protocols
Often endpoints are connected by multiple paths, but communications are usually restricted to a single path per connection. Resource usage within the network would be more efficient were it possible for these multiple paths to be used concurrently. Multipath TCP is a proposal to achieve multipath transport in TCP.
RFC6355 - Definition of the UUID-Based DHCPv6 Unique Identifier (DUID-UUID)
This document defines a new DHCPv6 Unique Identifier (DUID) type called DUID-UUID. DUID-UUIDs are derived from the already-standardized Universally Unique IDentifier (UUID) format. DUID-UUID makes it possible for devices to use UUIDs to identify themselves to DHC servers and vice versa. UUIDs are globally unique and readily available on many systems, making them convenient identifiers to leverage within DHCP. [STANDARDS-TRACK]
RFC6354 - Forward-Shifted RTP Redundancy Payload Support
This document defines a simple enhancement to support RTP sessions with forward-shifted redundant encodings, i.e., redundant data sent before the corresponding primary data. Forward-shifted redundancy can be used to conceal losses of a large number of consecutive media frames (e.g., consecutive loss of seconds or even tens of seconds of media). [STANDARDS-TRACK]
RFC6353 - Transport Layer Security (TLS) Transport Model for the Simple Network Management Protocol (SNMP)
This document describes a Transport Model for the Simple Network Management Protocol (SNMP), that uses either the Transport Layer Security protocol or the Datagram Transport Layer Security (DTLS) protocol.

This document lists a set of functional requirements that served as input to the design of Label Distribution Protocol (LDP) extensions for setting up point-to-multipoint (P2MP) Label Switched Paths (LSP), in order to deliver point-to-multipoint applications over a Multiprotocol Label Switching (MPLS) infrastructure.
RFC6347 - Datagram Transport Layer Security Version 1.2
This document specifies version 1.2 of the Datagram Transport Layer Security (DTLS) protocol. The DTLS protocol provides communications privacy for datagram protocols. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the Transport Layer Security (TLS) protocol and provides equivalent security guarantees. Datagram semantics of the underlying transport are preserved by the DTLS protocol. This document updates DTLS 1.0 to work with TLS version 1.2. [STANDARDS-TRACK]
RFC6346 - The Address plus Port (A+P) Approach to the IPv4 Address Shortage
We are facing the exhaustion of the IANA IPv4 free IP address pool. Unfortunately, IPv6 is not yet deployed widely enough to fully replace IPv4, and it is unrealistic to expect that this is going to change before the depletion of IPv4 addresses. Letting hosts seamlessly communicate in an IPv4 world without assigning a unique globally routable IPv4 address to each of them is a challenging problem.
RFC6345 - Protocol for Carrying Authentication for Network Access (PANA) Relay Element
This document specifies Protocol for carrying Authentication for Network Access (PANA) Relay Element functionality, which enables PANA messaging between a PANA Client (PaC) and a PANA Authentication Agent (PAA) where the two nodes cannot reach each other by means of regular IP routing. [STANDARDS-TRACK]
RFC6344 - Operating Virtual Concatenation (VCAT) and the Link Capacity Adjustment Scheme (LCAS) with Generalized Multi-Protocol Label Switching (GMPLS)
This document describes requirements for, and the use of, the Generalized Multi-Protocol Label Switching (GMPLS) control plane in support of the Virtual Concatenation (VCAT) layer 1 inverse multiplexing data plane mechanism and its companion Link Capacity Adjustment Scheme (LCAS).

This document revisits the dual-stack model and introduces the Dual- Stack Lite technology aimed at better aligning the costs and benefits of deploying IPv6 in service provider networks. Dual-Stack Lite enables a broadband service provider to share IPv4 addresses among customers by combining two well-known technologies: IP in IP (IPv4- in-IPv6) and Network Address Translation (NAT). [STANDARDS-TRACK]
RFC6332 - Multicast Acquisition Report Block Type for RTP Control Protocol (RTCP) Extended Reports (XRs)
In most RTP-based multicast applications, the RTP source sends inter- related data. Due to this interdependency, randomly joining RTP receivers usually cannot start consuming the multicast data right after they join the session. Thus, they often experience a random acquisition delay. An RTP receiver can use one or more different approaches to achieve rapid acquisition. Yet, due to various factors, performance of the rapid acquisition methods usually varies. Furthermore, in some cases, the RTP receiver can do a simple multicast join (in other cases, it is compelled to do so). For quality reporting, monitoring, and diagnostic purposes, it is important to collect detailed information from the RTP receivers about their acquisition and presentation experiences. This document addresses this issue by defining a new report block type, called the Multicast Acquisition (MA) report block, within the framework of RTP Control Protocol (RTCP) Extended Reports (XRs) (RFC 3611). This document also defines the necessary signaling of the new MA report block type in the Session Description Protocol (SDP). [STANDARDS-TRACK]

RFC6329 - IS-IS Extensions Supporting IEEE 802.1aq Shortest Path Bridging
802.1aq Shortest Path Bridging (SPB) has been standardized by the IEEE as the next step in the evolution of the various spanning tree and registration protocols. 802.1aq allows for true shortest path forwarding in a mesh Ethernet network context utilizing multiple equal cost paths. This permits it to support much larger Layer 2 topologies, with faster convergence, and vastly improved use of the mesh topology. Combined with this is single point provisioning for logical connectivity membership, which includes point-to-point, point-to-multipoint, and multipoint-to-multipoint variations. This memo documents the IS-IS changes required to support this IEEE protocol and provides some context and examples. [STANDARDS-TRACK]
RFC6328 - IANA Considerations for Network Layer Protocol Identifiers

This document provides NLPID IANA considerations. This memo documents an Internet Best Current Practice.
RFC6327 - Routing Bridges (RBridges): Adjacency
The IETF TRILL (TRansparent Interconnection of Lots of Links) protocol provides optimal pair-wise data forwarding without configuration, safe forwarding even during periods of temporary loops, and support for multipathing of both unicast and multicast traffic. TRILL accomplishes this by using IS-IS (Intermediate System to Intermediate System) link state routing and by encapsulating traffic using a header that includes a hop count. Devices that implement TRILL are called Routing Bridges (RBridges).
RFC6326 - Transparent Interconnection of Lots of Links (TRILL) Use of IS-IS
The IETF has standardized the Transparent Interconnection of Lots of Links (TRILL) protocol, which provides transparent Layer 2 forwarding using encapsulation with a hop count and IS-IS link state routing.

They achieve these goals using IS-IS routing and encapsulation of traffic with a header that includes a hop count.
RFC6324 - Routing Loop Attack Using IPv6 Automatic Tunnels: Problem Statement and Proposed Mitigations
This document is concerned with security vulnerabilities in IPv6-in- IPv4 automatic tunnels. These vulnerabilities allow an attacker to take advantage of inconsistencies between the IPv4 routing state and the IPv6 routing state. The attack forms a routing loop that can be abused as a vehicle for traffic amplification to facilitate denial- of-service (DoS) attacks. The first aim of this document is to inform on this attack and its root causes. The second aim is to present some possible mitigation measures. It should be noted that at the time of this writing there are no known reports of malicious attacks exploiting these vulnerabilities. Nonetheless, these vulnerabilities can be activated by accidental misconfiguration. This document is not an Internet Standards Track specification; it is published for informational purposes.

RFC6311 - Protocol Support for High Availability of IKEv2/IPsec
The IPsec protocol suite is widely used for business-critical network traffic. In order to make IPsec deployments highly available, more scalable, and failure-resistant, they are often implemented as IPsec High Availability (HA) clusters. However, there are many issues in IPsec HA clustering, and in particular in Internet Key Exchange Protocol version 2 (IKEv2) clustering. An earlier document, "IPsec Cluster Problem Statement", enumerates the issues encountered in the IKEv2/IPsec HA cluster environment. This document resolves these issues with the least possible change to the protocol.
