MPTCP v0.90 Release
The MPTCP v0.90 release is based on the Linux Kernel Longterm Support release v3.18.x. Its new features compared to the v0.89 release are:
- MPTCP Balia congestion control by Jaehyun Hwang and Anwar Walid (Bell Labs).
- TCP Fastopen support for Multipath TCP - draft-barre-mptcp-tfo (Gregory Detal and Sébastien Barré)
By using the same TFO-API as for regular TCP, you will be able to send data together with the SYN-segment. - Improved support for TCP socket-options (e.g., TCP_CONGESTION by Gregory Detal)
You can now correctly configure the congestion-control of the subflows by using the TCP_CONGESTION socket-option. - Support for stateless connection establishment (aka TCP SYN-Cookies)
Busy webservers can now use SYN-cookies to protect against SYN-flooding attacks. - Addition of MIB/SNMP counters for statistics-tracking and debugging
Monitor the state of your MPTCP-host by looking at the statistics with "netstat -s" (use of our own net-tools package is required) - The usual performance improvements and bug-fixes.
- Lots of cleanup from Octavian Purdila and his team at Intel (Doru Gucea,...)
This release has seen a total of 112 commits.
