Abstract

Systems and methods for implementing communication in a multiprocessor are disclosed. In one exemplary implementation a first processor receives a request to provide a communication resource for an application executing on the first processor to communicate with a remote application. In response to the communication request, the first processor opens a communication resource on a second processor, and manages communication operations between the application executing on the first processor and the remote application using the communication resource on the second processor.

Claims

1. A computing system, comprising:

a first processor and a second processor;

first network communication resources operable on the first processor that enable network communication operations;

second network communication resources operable on the second processor that enable network communication operations;

inter-processor communication resources operable on the first processor and the second processor that enable communication between the first processor and the second processor; and

a demultiplexer module operable on the first processor that enables network communication operations between an application executing on the first processor and a remote application using the second network communication resources.

2. The computer system of claim 1, wherein the network communication between the resources on the first and second processors proceeds on a first channel and communications between the first processor and remote application proceeds on a second different channel.

3. The computer system of claim 2, wherein at least a portion of the communication required by the remote application travels from the second processor to the first processor and subsequently to the remote application.

4. The computing system of claim 1, wherein the first network communication resources comprises a local socket I/O API that provides an interface with an underlying communication protocol stack executing on the first processor.

5. The computing system of claim 1, wherein the second network communication resources comprises a local socket I/O API that provides an interface with an underlying communication protocol stack executing on the second processor.

6. The computing system of claim 1, wherein the inter-processor communication resources implement remote procedure calls to communicate via a shared memory module.

7. The computing system of claim 1, wherein the demultiplexer module assigns communication resources to communication requests.

8. The computing system of claim 1, wherein the demultiplexer module manages a plurality of data tables that provide a mapping between a communication resource and specific communication operations that may be implemented by the communication resource.

9. The computer system of claim 1, wherein a remote application comprises application module that creates an endpoint for communication with at least one external device.
