Cross network bridging

A cross-network bridging apparatus, comprising:

• a bus interface for connecting to a first system bus;
• and
• bridging circuitry, to:
• receive, over the first system bus, one or more outbound system-bus transactions that are intended for transfer to a second system bus coupled to a remote processor or device, the remote processor or device being located across a network from the apparatus;
• translate the one or more outbound system-bus transactions into one or more outbound network packets to be transferred over the network, for injecting the one or more outbound system-bus transactions to the second system bus;
• receive one or more inbound network packets that arrive over the network and that convey one or more inbound system-bus transactions produced by the remote processor or device;
• extract the one or more inbound system-bus transactions from the received one or more inbound network packets;
• and
• inject the one or more inbound network packets to the first system bus.

• and
• a network adapter to send the one or more outbound network packets over the network,
• wherein the bridging circuitry is to send the one or more outbound system-bus transactions to the network adapter by writing the one or more outbound system-bus transactions to a memory accessible to the network adapter.

A cross-network bridging method, comprising:

• in a Cross-Network Bridge (CNB), monitoring system-bus transactions that are communicated on a first system bus coupled locally to the CNB;
• identifying, from among the monitored system-bus transactions, one or more outbound system-bus transactions that are intended for transfer to a second system bus coupled to a remote processor or device, the remote processor or device being located across a network from the CNB;
• and
• translating the one or more outbound system-bus transactions into one or more outbound network packets to be transferred over the network, for injecting the one or more outbound system-bus transactions to the second system bus.

• sending the one or more outbound network packets over the network using a network adapter, by writing the one or more outbound system-bus transactions to a memory accessible to the network adapter.
