Abstract: A method, non-transitory computer readable medium, and network traffic management apparatus that selects a first one of a plurality of Short Message Service Center (SMSC) servers based on a load balancing decision in response to an external short messaging entity (ESME) SMPP request message received from a first one of a plurality of ESMEs. A first sequence number is generated for the ESME SMPP request message. The first sequence number is stored in a first entry of a mapping table as associated with a sequence number included in the ESME SMPP request message and an indication of the first one of the plurality of SMSC servers. The sequence number included in the ESME SMPP request message is replaced with the first sequence number. The ESME SMPP request message is sent to the first one of the plurality of SMSC servers.

Abstract: Embodiments may be directed towards enabling one or more load balance servers to maintain connection flow persistence if the server initiates to the communication to a client. A packet traffic management device may (PTMD) intercept the request from the server and generate reverse persistence information. The PTMD may include a portion of the reverse persistence information in the request before forwarding the request to the targeted client device. The client device may send the response to the PTMD. The PTMD may employ reverse persistence information to identify the target server. The PTMD may remove the reverse persistence information from the response sent by the client and forward the response to the determined server. Removing the reverse persistence information may remove evidence that the PTMD intervened in the connection between the client and server.

Abstract: A traffic management device (TMD), system, and processor-readable storage medium directed towards automatically configuring an AAA proxy device (also referred to herein as “the proxy”) to load-balance AAA request messages across a plurality of AAA server devices. In one embodiment the proxy receives an AAA handshake message from an AAA client device. The proxy forwards the handshake message to each of the plurality of server devices and, in reply, receives an AAA handshake response message from each of the plurality of server devices. The proxy extracts attributes from each of the handshake response messages and automatically configures itself based on the extracted attributes. The proxy then load-balances, modifies and/or routes subsequently received AAA request messages based on the extracted attributes.
