SYSTEMS AND METHODS FOR DIAMETER LOAD BALANCING

摘要

The present disclosure is directed generally to systems and methods for Diameter load balancing. In some embodiments, an intermediary device may receive a diameter connection request from a client that includes a CER. The intermediary device may initiate a connection with a server of a plurality of servers and place the server protocol control block in a reuse pool. Responsive to opening the connection with the server, the intermediary device may forward the received CER. The intermediary device may then receive a CEA message from the server and establish an AVP-based persistent connection. The intermediary device may modify the received CEA message, and then forward the message to the client. When the intermediary device receives a diameter message from a client, the intermediary device may match an AVP of the message with an AVP associated with a persistent server connection, and forward the diameter message to the corresponding server.

1. A method of diameter load balancing via an intermediary device, comprising:
receiving, by a virtual server executing on a device intermediary to a client and a plurality of diameter servers, a message communicated from the client via a diameter protocol; selecting, by the device, a diameter server of the plurality of diameter servers based on an attribute-value pair in the message; and forwarding, by the device, the message to the selected diameter server of the plurality of diameter servers.
