Abstract: Some embodiments of the invention provide a method for forwarding data messages between a client and a server (e.g., between client and server machines and/or applications). In some embodiments, the method receives a data message that a load balancer has directed from a particular client to a particular server after selecting the particular server from a set of several candidate servers for the received data message's flow. The method stores an association between an identifier associated with the load balancer and a flow identifier associated with the message flow, and then forwards the received data message to the particular server. The method subsequently uses the load balancer identifier in the stored association to forward to the particular load balancer a data message that is sent by the particular server. The method of some embodiments is implemented by an intervening forwarding element (e.g., a router) between the load balancer set and the server set.

Abstract: Some embodiments provide a novel method of performing health monitoring for resources associated with a global server load balancing (GSLB) system. This system is implemented by several domain name system (DNS) servers that perform DNS services for resources located at several geographically separate sites. The method identifies several different groupings of the resources. It then assigns the health monitoring of the different resource groups to different DNS servers. The method then configures each particular DNS server (1) to send health monitoring messages to the particular group of resources assigned to the particular DNS server, (2) to generate data by analyzing responses to the sent health monitoring messages, and (3) to distribute the generated data to the other DNS servers. The method in some embodiments is performed by a set of one or more controllers.
