[Olsr-dev] [PATCH v1 0/3] Use bandwidth during gateway selection
Fri Jul 27 14:24:03 CEST 2012
Are these (A)DSL links double asymmetric, e.g. 2Mbps/2Mbps and 4Mbps/512kbps and 20Mbps/64kbps?
I hope to have multipath implemented one day, where MPTCP will use the best links (with s !!). It takes utilization, loss rations etc. into account. Directing MPTCP to make use of multiple SamrtGW tunnels & the local exit links is still a raw sketch. It would pick best links for uplink and downlink separately.
My experience with 2G - 3G (no 4G in NLD) and satcom is that good feedback of data rates is hard to get. For fixed lines, human configuration could be error-prone.
