PACKET I/O SUPPORT FOR A LOGICAL SWITCH ROUTER ARCHITECTURE

摘要

A tool for packet transmission and delivery in a distributed system. The tool determines one or more packets is classified as a L3 packet. The tool determines translation of the one or more packets classified as L3 packets to one or more corresponding net devices. The tool sends the one or more packets classified as a non L3 packet to a user space packet dispatcher service.

主权项

1. A computer system having a logical switch architecture supporting a layered architecture for packet I/O in a distributed system, the computer system comprising:
one or more computer processors; one or more computer readable storage media; program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising: a first software module configurable to determine a first level packet classification for one or more packets destined in the distributed system; a second software module configurable to determine a second level packet classification for the one or more packets in the distributed system; and a third software module configurable to register one or more applications included within one or more logical switch routers in the distributed system with the second software module to filter the one or more packets in the distributed system.
