The keyword above is "may". Without network buffering, ongoing TCPÂ connections "may" be hung, depending on whether any communicationÂ

from no-network buffering as it eliminates the latency overhead introduced by buffering every packet [ 0.5 x checkpoint-interval + RTT between primary-backup].  Ian. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
