Comparisions of network protocol performance?

» close window

The Question is:

 
Dear  Sir
 
       I would like to ask you about ther performance fo Decnet protocol
when compares to
another well known protocols like TCP , IPX on LAN and WAN. Moreover, which
concept
is better in the performance issue between transparent and non-transparent
task to task
especially WAN.  Thanks very much .

The Answer is :

 
  Network protocols are network protocols, and all network protocols must
  perform the same basic operations -- the performance of network protocols
  intended for similar purposes will all tend to be rather similar.
 
  You can use tools such as DTS/DTR to compare the performance of DECnet
  links, and tools such as the ICMP PING tool on IP networks.  Most (all?)
  modern network protocols will each provide similar portions of the
  available hardware bandwidth, typically closely tracking the available
  hardware bandwidth underlying the connections.
 
  Specific protocols have advantages and disadvantages, and a discussion
  of what application requirements are present will be required as part
  of any decision.  DECnet, for instance, supports remote file access via
  FAL, an application that is not available on other platforms.  UDP/IP,
  for instance, is well-suited to multipoint datagram communications.
 
  "Transparent" and "non-transparent" communications are DECnet concepts,
  and indicate little more than the level of involvement in the DECnet
  connection request and connection reception processing.
