Abstract

In a multinode network of store and forward data switching exchanges-- for switching and communication of data messages relative to communication links (or channels) in multibit packet units--the problem of congestion due to overloaded links can be eased by providing more efficient handling of bulk traffic (e.g., large numbers of messages having common origin and destination).

Efficient Data Transfer in Packet Switched Networks

In a multinode network of store and forward data switching exchanges-- for switching and communication of data messages relative to communication links (or channels) in multibit packet units--the problem of congestion due to overloaded links can be eased by providing more efficient handling of bulk traffic (e.g., large numbers of messages having common origin and destination).

Such traffic may be identified in control communications and utilized for allotment of buffer and channel capacity (at origin and destination nodes and intermediate nodes) sufficient to permit uninterrupted handling of the entire bulk message aggregate, without intervening control communications between individual message segments.

Transfers of message constituents of a bulk aggregate between source and intermediate nodes and between successive intermediate nodes can be carried out concurrently. Thus, the delays and communication cost overhead associated with transmission of control information for single messages can be effectively reduced or curtailed for bulk aggregates, thereby reducing the loading of the network.
