Abstract
A system and method for communicating messages between nodes of a packet switched communications network, with each message having a defined message type and including message content. The system includes one or more second level channel interface devices connected with a first node for tracking information relating to bi-directional communication of packets over a communications channel established between the first and second network nodes; a device for receiving packets associated with messages from the first node and generating message flits associated with the messages for communication over the channel based on message content associated with the received message packets; a device for receiving message flits associated with messages communicated from a second node and received via the channel and generating corresponding message packet content for storage at the first node; and, one or more first level channel interface devices associated with one or more second level channel interface devices and interfaced to a network switch device at each first and second node for communicating flits to and from a respective first and second node via the channel, wherein the communication…
