ARCHITECTURE FOR STRETCHING LOGICAL SWITCHES BETWEEN MULTIPLE DATACENTERS

摘要

Some embodiments provide a system for implementing a logical network that spans multiple datacenters. The system includes, at each of the datacenters, a set of host computers that execute (i) data compute nodes (DCNs) belonging to the logical network and (ii) managed forwarding elements (MFEs) that implement the logical network to process data messages for the DCNs executing on the host computers. The system also includes, at each of the datacenters, a set of computing devices implementing logical network gateways for logical forwarding elements (LFEs) of the logical network. The logical network gateways are connected to the logical network gateways for the LFEs at the other datacenters. The MFEs executing on the host computers in a first datacenter communicate with the MFEs executing on the host computers in a second datacenter via the logical network gateways of the first and second datacenters.
