Multi-Path TCP (MPTCP) is an effort towards enabling the simultaneous use of several paths by a modification of TCP that presents a normal TCP interface to applications, while in fact spreading data across several subflows. Benefits of this include better resource utilization, better throughput obtained thanks to the resulting pooling of network resources, and smoother reaction to failures. An IETF working group has recently formed to develop that protocol, and UCLouvain, together with other partners from the Trilogy project, has started implementing the protocol.

Shim6 is a multihoming protocol that has been designed by the IETF to suit the requirements of the new version of IP, IPv6. Currently BGP is used to provide multihomed connectivity to sites, but this technique is already now responsible for part of the growth of the BGP routing tables, and it could be even worth with the very long IPv6 addresses. This presentation explains the motivations that led to the design of Shim6, and goes through its functional and security challenges. We conclude with some open research areas.

The growth of the Internet is causing some stress on the Internet control plane and BGP in particular. The IRTF Routing Research Group has been chartered to explore architectural alternatives to the current Internet routing architecture. Several of these alternatives rely on separating the identifier and locator roles of IP addresses. In this talk, we'll review the key principles of these proposals and explain the main challenges that need to be solved.

LinShim6 0.8 has been released.

LinShim6 is an implementation of the Shim6 protocol, that provides host-centric multihoming capabilities to IPv6.
The major new feature present in version 0.8 is the support for locator updates, that is, the peer is now informed when new locators become locally available.
