PeSIT is an open file transfer protocol often associated with Axway.
Like Sterling Commerce’s proprietary NDM file transfer protocol, PeSIT has now been written into the standard communication specifications of several industry consortiums and government exchanges, thus ensuring a high degree of long-term dependence on Axway technology. PeSIT is required far more often in Europe than in the United States due to Axway’s French roots and home turf advantage.
Also like NDM, PeSIT is normally used in internal (or trusted WAN) transfers; other protocols are typically used for transfers across the Internet.
PeSIT stands for “Protocol d’Echanges pour un Systeme Interbancaire de Telecompensation” and was designed to be a specialized replacement for FTP to support European interbank transactions in the mid-1980’s. One of the primary features of the protocol was “checkpoint restart”.
BEST PRACTICE: PeSIT, NDM and other protocols should be avoided in new deployments unless specifically mandated by industry rule or statute. The interesting capabilities these protocols offer (e.g., checkpoint restart, integrity checks, etc.) are now also available in vendor-neutral protocols, and from vendors who allow wider and less expensive licensing of connectivity technology than Axway and Sterling Commerce (now IBM).
