The OS 2200 communications management system includes CPComm and MCB along with many programs that provide communications related functions such as file transfer, e-mail, and distributed transaction processing protocols. center == CPComm == CPComm executes as a real time program in a background run.〔Unisys Corporation (2013). Communications Platform Configuration and Operations Guide. (Unisys publication 7844 8438). Roseville, MN. http://public.support.unisys.com/2200/docs/cp14.0/pdf/78448438-017.pdf〕 CPComm implements the protocol stacks. CPComm communicates with the CIOP (Communications I/O Processor) to connect to networks. CPcommOS is a variant for 2200 Series systems implemented on Intel architectures. In the most recent systems only various speeds of Ethernet communications are supported. Previous systems supported ATM and FDDI but these were dropped through lack of interest. CPComm and the Exec jointly handle authentication of connection requests and authorization for users and terminals to connect to time-sharing, and the various transaction application groups. SSL is supported for every connection. CPComm has software implementations of the encryption algorithms required for SSL. CPComm includes the protocols and connections to time-sharing and transaction message queues. One of the most heavily used legacy protocols is INT1 which is a TCP/IP variant of the UNISCOPE/UTS green-screen terminal protocol. TCP/IP v4 and TCP/IP v6 along with SNMP v1 and v3 are supported by CPComm. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Unisys OS 2200 communications」の詳細全文を読む スポンサード リンク
