From: Curtis Villamizar <curtis@ans.net> LQM on non-PPP links sure would be great. A number of times I've suggested we consider LQM on bcast, with a set of LQM parameters per ARP entry. This way one end sends a LQM packet that serves as a time marker, counts packets, then includes the count in the next LQM time marker. The receiver needs only count packets between LQM packets and compare the local count against the count sent by the other end. This is an enormously oversimplified summary of LQM, but it just to make the point that LQM is Good Stuff.
Yes, but a bit tough on broadcast, as you would need all nodes sending a history of all the other LQM counts it heard. Quite a big packet or set of packets with many nodes participating. What might be a better idea is to add it to BGP-n. Say between routing peers. That's what I did for IPng, in my (now mangled) Neighbor Discovery.
In the absence of LQM we have the DS3 MIB (poor substitute)
Hey, the original PPP LQM was designed and built for DS3 (at Network Systems). NSFnet was very interested at the time. Aren't we already running PPP LQM for all the DS3's? PPP LQM was one of the reasons for PPP/FrameRelay, too. Bill.Simpson@um.cc.umich.edu Key fingerprint = 2E 07 23 03 C5 62 70 D3 59 B1 4F 5E 1D C2 C1 A2
