Persistent connections in high speed internets

The authors examine persistent connections as a part of the very high speed internet (VHSI) abstraction proposed by G.M. Parulkar (see ACM SIGCOMM Computer Communications Review, p.18, 1990). An important component of the VHSI is a novel multipoint congram-oriented high-performance internet protocol (Mchip). The congram is the basic service primitive of Mchip which incorporates strengths of both connection and datagram approaches. Mchip supports two types of congrams: the user congram (UCon) and the persistent internet congram (PICon). The authors evaluate the need for PICons, and their place in the VHSI model. They focus on the PICon control packet organization and present examples of PICon setup and use. Future research directions are identified.<>
