I am doing a survey on available TCP/IP implementations over DDN Standard X.25 and would appreciate any and all information on the following aspects (the vendor guide form the NIC doesn't go into sufficient detail): 1) which implementations negotiate precedence for a DDN Standard X.25 call as defined on page 1-481 (volume 1) of the DDN Protocol Handbook and the mapping of precedence from IP to DDN Standard X.25 as defined on 1-494 of the same. Additionally, what mechanisms are provided allow a user or application process (i.e. FTP, Telnet, etc) to specify the precedence of a session so that the precednce level is passed down to the IP layer? 2) which implementations can utilitize DDN X.25 Logical addressing as specified in pages 1-495 thru 1-498 of the DDN Protocol Handbook - which includes mapping from IP addresses (either fully implemented or partially implemented)? many thanks for your help!
