Protocol Issues in Providing 64 kbps SATCOM Links
Defence Research Agency, DRA Defford.
1995
This project built upon earlier work analysing the performance of packet
data links for military satellite networks. Previous work had primarilly
considered data rates less than 64 kbps, this study extended the work to
cover transmission at or above 64 kbps. Such factors as design of EPM modems
were considered, together with the configuration requirements for the X.25
and TCP/IP protocols.
The work also assessed the need for a super-extended HDLC link window size,
and implemented such a scheme within a simulation environment. The architecture
of equipment needed to perform protocol conversion/enhancement was considered.
The concepts developed could be used within an enhancer as depicted below
which shows two users (u1, u2) using a pair of protocol enhancers (e1 and
e2) inserted between the terrestrial network interface (n1 and n2) and the
SATCOM terminal.
