925.0. "IP packet switching" by CHEFS::16.43.128.170::WorkBenchUser () Thu Feb 13 1997 04:48

A question on IP packet switching on the GS/FDDI, (IPPS).   How does IPPS
handle hunt groups between gs/fddi ? Can we define ipsubnets to the virtual 
ports.  Also if we have a large number of gs/fddi connected together does this 
affect ipps.  Basically how does this scale.

    IP packet switching deals with bridge ports, not physical port, so it
    considers a hunt group to be one port.  You can define an IP address
    range for a hunt group port just as you can for a plain old bridge
    port.  (The IP address range is a generalization of subnets; to define
    a subnet 16.20.xx.xx, you would set up a range of 16.20.0.0 to
    16.20.255.255.)
    
    IP switching should not significantly affect flooding performance, and
    that's the only performance impact I could forsee.  Aside from that,
    the only scaling issue I can imagine is that configuration might become
    cumbersome if you have a large switched network, at least until we
    implement dynamic links.  That would allow IP address range information
    to be distributed network-wide; until then every IP address range will
    have to be configured at all switches.
