Import a clean-room implementation of the VEGAS congestion control algorithm
based on the paper "TCP Vegas: end to end congestion avoidance on a global internet" by Brakmo and Peterson. It is implemented as a kernel module compatible with the recently committed modular congestion control framework. VEGAS uses network delay as a congestion indicator and unlike regular loss-based algorithms, attempts to keep the network operating with stable queuing delays and no congestion losses. By keeping network buffers used along the path within a set range, queuing delays are kept low while maintaining high throughput. In collaboration with: David Hayes <dahayes at swin edu au> and Grenville Armitage <garmitage at swin edu au> Sponsored by: FreeBSD Foundation Reviewed by: bz and others along the way MFC after: 3 months
