Load balancing in a logical pipeline

摘要

A non-transitory machine readable medium storing a program that configures a managed forwarding element to perform logical L2 switching and L3 routing is described. The program generates a first set of flow entries for configuring the first managed forwarding element to perform (1) a first logical L2 processing for a first logical L2 domain, (2) a logical L3 processing, (3) a load balancing processing to select a second managed forwarding element from a plurality of managed forwarding elements to which to forward packets and (4) a logical ingress L2 processing for a second logical L2 domain on the packets. The program generates a second set of flow entries for configuring the second managed forwarding element to perform a second logical L2 processing for a second logical L2 domain on the packets.

1. A non-transitory machine readable medium storing a program which when executed by at least one processing unit configures a plurality of managed forwarding elements (MFEs) to implement a logical L3 router and a plurality of logical L2 switches that each logically couple to a plurality of machines, the program comprising sets of instructions for:
for each MFE of a set of MFEs that implement a particular logical L2 switch, generating a first set of data records for configuring the MFE to install a first set of flow entries that implement the particular logical L2 switch and the logical L3 router for processing packets sent to a network address that logically couples to the particular logical L2 switch; and for each MFE of the set of MFEs, generating a second set of data records for configuring the MFE to install a second set of flow entries that implement load balancing processing on a subset of packets sent to the network address that logically couples to the particular logical L2 switch, the second set of flow entries specifying to balance the subset of packets across a plurality of machines that logically couple to the particular logical L2switch and are physically coupled to a plurality of different MFEs.
