We are happy to announce the release of INET Framework 2.3. This version adds spanning tree support to Ethernet switches (both STP and RSTP), several new routing protocols (RIP, GPSR, DYMO), a NetFilter hook API to facilitate the implementation of reactive routing protocols and several other tasks; an improved DHCP model; CMT, NAT and IPv6 support for SCTP; and contains many other improvements and bug fixes.

INET is an open-source communication networks simulation package for the OMNeT++ simulation environment. It contains models for several wired and wireless networking protocols, including UDP, TCP, SCTP, IP, IPv6, Ethernet, PPP, 802.11, MPLS, OSPF, and many others.
