1292.0. "DECnet over Frame Relay" by HGOVC::SHUMCF () Tue Apr 08 1997 12:15

    We have a difficult situation to explain why DECnet perform badly than
    other protocols such as IP over Frame Relay when using DECbrouter. We
    understand the problem is not on the DECbrouter because we ever tested
    it with Cisco router 2501 and RouteAbout Access EW. The test is
    conducted by using Pathwork file transfer between two PC on each end.
    The network connection is created by Frame Relay circuit using two
    routers (either DECbrouter or Cisco 2501 or RouteAbout). We found the
    file transfer of 2MB file cannot saturate the 64k Frame Relay circuit
    but IP with larger frame size can. Nevertheless, RouteAbout is doing a 
    little better than DECbrouter and Cisco.
    
    Could anyone kindly explain the protocol limitation of DECnet in more 
    technical details because I'm not an expert in DECnet.
    
    Thanks in advance,
    cf

1292.1What version if IOS?FOUNDR::SHEEHANFri May 16 1997 14:1910
 Hi cf,

 From what I've been told... This is the nature of Cisco's
 implemention of DECnet routing over a Frame Relay circuit.
 However newer code may be more efficient. What version of
 the IOS are you running?
