1882.0. "Multicast rate for ASE?" by RDMCS3::STUART (Scott Stuart - NPB SE - 410.315.9954) Thu Feb 13 1997 10:32

    It is my understanding that ASE systems use a multicast message to
    communicate with each other.
    
    1) Is this correct?
    
    2) What is the multicast and broadcast rate, both in packets and bytes per
    second, for two ASE systems?
    
    3) Where can I find details on the structure of this multicast message?
     
     I am supporting the Digital network infrastructure at AOL where 
    multiple pairs of ASE systems are all on one large extended FDDI LAN.
    What I would like to do is to filter these multicast  messages so that 
    they only go to the appropriate partner system.  There is some evidence
    that the overall broadcast/multicast rate is high on the extended LAN.
    
    Thanks for your help.
    
    regards,
    scott

    ASE does not use multicast addresses.  The network interface test code
    in ASE will use broadcast only if DLI functionality is not configured
    into the running kernel.  This is configured in by default.  So out of
    the box, no multicast or broadcast should be produced by ASE.

    Thanks.  I do have a few other questions to make sure I understand.
    
    On a large extended LAN with each ASE servers on a separate segment, 
    there should be no extra broadcast or multicast traffic due to ASE?  
    
    In other words, there would be no benefit to filtering certain 
    multicast or broadcast traffic between switch ports at least as far as 
    ASE traffic is concerned?
    
    What type of message is sent between two ASE servers?  Unicast via a
    MAC address or IP address? other?
