File Transfer Services (FTS) is a general utility system that allows for the transmission of files between different computers on the same or different networks. FTS supports high speed bulk transfers, concurrent transmissions, automatic restart following failure, extensive security and monitoring, and allows for transfers between diverse system types including MVS, DOS, VM, MSP, FSP, PC's and TANDEM systems.
FTS supports the transmission of 16 concurrently to each of any number of SOLVE, NET/MASTER and Nonstop NET/MASTER systems and the receipt of up to 16 files concurrently.
Each potential transfer needs to have a transmission definition created for it that identifies the names and details of the files to be transferred and the location of the other system. There are a number of different ways to store FTS transmissions. Once a definition has been created the transmission can be executed whenever the content of the source file is to be transferred to the destination file (after any file allocations specified as part of the definition). After the transmission has successfully executed any subsequent jobs to be executed on either the source or destination machine (or both) that is specified in the definition will be run. Transmission requests are scheduled and will be handled by an FTS transmission initiator at the scheduled time or as soon afterwards as an initiator becomes available.
FTS uses sophisticated data compression and compaction algorithms that can result in significant reduction in transmission times and line traffic. Three types of compression may be selected. These are blank compression which eliminates string of blank characters, like string compression which compacts strings of like characters, and data compaction which uses a bit-orientated algorithm.
