Abstract
One embodiment of the present invention provides a method for processing a remote interrupt signal or a remote event. Another embodiment of the present invention provides a system for issuing a raw packet over a network in response to a remote interrupt or a remote event. Another embodiment of the present invention provides a network interface system configured to issue interrupt requests over a network.
Claims22
A method for processing a remote interrupt signal, the method comprising:
- storing a plurality of raw packets in a raw packet buffer, each raw packet including an identity of an interrupt signal source;
- receiving an interrupt signal from a first interrupt signal source at a remote node;
- selecting a raw packet from the raw packet buffer based on the received interrupt signal, the selected raw packet including the identity of the first interrupt signal source;
- and
- issuing the selected raw packet over the network from the remote node to a host node.
A system for issuing a raw packet over a network in response to a remote interrupt, the system comprising:
- a host node including a processing unit, the host node operatively coupled to the network and for receiving an issued raw packet;
- and
- a remote node including a network interface module, an interrupt signal source, and a raw packet buffer for storing a plurality of raw packets, each raw packet including an identity of an interrupt signal source, the network interface module for issuing to the host node a raw packet selected from the raw packet buffer based on an interrupt signal received from the interrupt signal source.
In a remote node, a network interface system comprising:
- a raw packet buffer for storing a number of raw packets, each raw packet containing an identity of a corresponding interrupt signal source, and in response to an interrupt signal source providing an interrupt signal to the network interface system, the network interface system selecting a corresponding raw packet from the raw packet buffer and issuing the corresponding raw packet from the remote node to a host node via a network.
