发明名称 Enabling Hardware Switches to Perform Logical Routing Functionalities
摘要 A managed hardware forwarding element (MHFE) that performs packet forwarding operations for a logical network is described. The MHFE receives configuration data for the logical network that defines a logical router and a set of logical switches for logically connecting several end machines that operate on different host machines to several physical machines that are connected to the MHFE. The logical router also includes multiple routing components. The MHFE also receives a first forwarding table and a second forwarding table. The first forwarding table stores linking data for each logical port of each logical switch in the set of logical switches that identifies a corresponding routing component in the logical router. The second forwarding table stores a set of routes for each routing component of the logical router. The MHFE uses the first and second forwarding tables to perform packet forwarding operations at the MHFE.

主权项 1. A method for using a managed hardware forwarding element (MHFE) to perform packet forwarding operations for a logical network, the method comprising: receiving, at the MHFE, configuration data for the logical network that defines a logical router and a set of logical switches for logically connecting a plurality of end machines operating on a plurality of host machines to a plurality of physical machines that are connected to the MHFE, the logical router comprising a plurality of routing components; receiving, at the MHFE, a first forwarding table and a second forwarding table, the first forwarding table storing a linking data for each logical port of each logical switch in the set of logical switches, wherein the linking data for a logical port of a logical switch is for identifying a corresponding routing component in the logical router,the second forwarding table storing a set routes for each routing component of the logical router; and using the first and second forwarding tables to perform packet forwarding operations at the MHFE.
