VIRTUAL MEMORY PROTOCOL SEGMENTATION OFFLOADING |
摘要 |
Methods and systems for a more efficient transmission of network traffic are provided. According to one embodiment, payload data originated by a user process running on a host processor of the computer system is fetched by an interface of the computer system by performing direct virtual memory addressing of a user memory space of a system memory of the computer system on behalf of a network processor of the computer system. The direct virtual memory addressing maps a physical address of the payload data to a virtual address. The payload data is segmented by the network processor across one or more packets. |

1. A method of performing segmentation offloading, the method comprising:
fetching, by an interface of a computer system, payload data originated by a user process running on a host processor of the computer system by performing direct virtual memory addressing of a user memory space of a system memory of the computer system on behalf of a network processor of the computer system, wherein said direct virtual memory addressing maps a physical address of the payload data to a virtual address; and segmenting, by the network processor, the payload data across one or more packets. |
