Connection Management and File Transfer Protocols for the DTNSRDC (David Taylor Naval Ship Research and Development Center) Hyperchannel Network

摘要

This report describes two sets of protocols implemented on DTNSRDC's Hyperchannel based local area network. The first protocol set facilitates local area network connections among arbitrary processes running on computers attached to DTNSRDC's Hyperchannel network. The second protocol set provides a mechanism for allowing local area network hosts (computers connected via the Hyperchannel) to store, retrieve, and delete files on other network hosts. The base protocol implemented on the Hyperchannel is a general purpose network connection management protocol. The network connection protocol (NCP) is intended to allow any network host to support up to 255 simultaneous logical connections between itself and remote hosts. This protocol makes no specific provisions to ensure data integrity or flow control. Instead, the Hyperchannel hardware is relied upon to provide these services. In most cases this will be sufficient.
