Abstract

A method and system for increasing throughput of incoming data and outgoing data through buffer manipulation is described. A channel connection is provided for determining which buffers are used for reading incoming data. Buffer manipulation includes enabling the reading of a subset of the incoming data directly into an application buffer associated with an application when a first set of criteria is met and enabling the reading of existing data from an intermediate buffer and storing the subset of the incoming data in the intermediate buffer when a second set of criteria is met.

Claims

1. A method comprising:

receiving at a first peer computer incoming data from a second peer computer;

in response to receiving the incoming data, determining if an application buffer or an intermediate buffer is to be used;

enabling reading of a subset of the incoming data directly into the application buffer associated with an application when a first set of criteria is met; and

enabling reading of existing data from the intermediate buffer and storing the subset of the incoming data in the intermediate buffer when a second set of criteria is met.

2. The method of claim 1, further comprising notifying a first peer connection associated with the first peer computer when the incoming data arrives at the first peer computer.

3. The method of claim 1, wherein the first set of criteria includes that the intermediate buffer is empty.

4. The method of claim 1, wherein the second set of criteria includes at least one of a group consisting of:

data is found in the intermediate buffer; and

the application has not provided information associated with the intermediate buffer.

5. The method of claim 1, wherein enabling reading of the subset of the incoming data directly into the application buffer further comprising communicating with a channel connection associated with the application at the first peer computer to obtain memory location information of the application buffer.

6. The method of claim 5, further comprising passing the memory location information to a first peer connection associated with the first peer computer, wherein the first peer connection is used for connecting with the second peer computer.

7. The method of claim 1, further comprising enabling multithreaded access to the intermediate buffer.

8. The method of claim 1, wherein the intermediate buffer is a circular buffer associated with a channel connection for the application.

9. The method of claim 1, further comprising providing the first peer connection direct access to a respective application buffer that has outgoing data to access the outgoing data for transport from the first peer computer.

10. The method of claim 1, further comprising, when a decision is made to store the subset of the incoming data in the intermediate buffer, storing the subset of the incoming data in the intermediate buffer in a sequence that the subset of the incoming data is received.

11. A system for peer computer-to-peer computer communication, the system comprising:

at least one peer connection at a first peer computer of a plurality of peer computers, the at least one peer connection is in connection with a second peer computer when the first peer computer and second peer computer are in communication;

a plurality of application buffers associated with corresponding applications at the first peer computer;

a plurality of channel connections associated with corresponding applications at the first peer computer, the respective channel connection for determining if a first set criteria or a second set of criteria is satisfied and for enabling a respective subset of incoming data from a second peer computer to be read directly into a respective application buffer of the plurality of application buffers when the first set of criteria is satisfied; and

a plurality of intermediate buffers corresponding to the applications, wherein the channel connection enables the subset of the incoming data to be stored in a respective intermediate buffer when the second set of criteria is satisfied.

12. The system of claim 11, further comprising a read interface associated with a respective channel connection.
