Abstract
A method, system and apparatus for improving network performance of a multiprocessor system that has a limited number of physical network interfaces by using virtual IP addresses are provided. When a processor of the multiprocessor system determines that it is processing network data, it uses a virtual IP address to transmit the data. The virtual IP address is associated with a buffer; and thus the data is sent to the buffer. This allows the processor to be free to process other data, network or otherwise. The buffer, with the help of a controller, then contends for the use of one of the limited physical network interfaces to transmit the data.
Claims20
A method of improving performance in a multiprocessor system that uses a limited number of physical interfaces to transact network data comprising the steps of:
- determining whether data being processed is network data;
- and
- transacting, if the data is network data, the data using a virtual Internet protocol (IP) address.
A computer program product on a computer readable medium for improving performance of a multiprocessor system that uses a limited number of physical interfaces to transact network data comprising:
- code means for determining whether data being processed is network data;
- and
- code means for transacting, if the data is network data, the data using a virtual Internet protocol (IP) address.
An apparatus for improving performance of a multiprocessor system that uses a limited number of physical interfaces to transact network data comprising:
- means for determining whether data being processed is network data;
- and
- means for transacting, if the data is network data, the data using a virtual Internet protocol (IP) address.
A multiprocessor system having means for improving performance comprising:
- at least one memory device to store code data;
- and
- using one of the processors processor for processing the code data to determine whether data being processed is network data and to transact, if the data is network data, the data using a virtual Internet protocol (IP) address.
