Comments on using a TCP socket to discover the Path MTU to a fileserver, e.g. when an Rx connection is made, a connection to a TCP socket, presumably port TCP 7000, is made, and the discovered PMTU if any is applied to Rx connections to that fileserver? Notes: 1) this would not block establishment of a connection 2) this *would* use extra bandwidth as the path MTU needs to be established 3) this would require any firewalls allow the TCP connection (if not, no change) 4) even if a value is established, there's no guarantee it's accurate as routers could send UDP and TCP via different routes 5) routers may cheat and make the discovered value invalid anyway -- Derrick _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
