摘要： Session persistence storage schemes are provided. These schemes may include identifying a change in a session attribute for an application client session, querying a session persistence table associated with the application running in the application-server environment, and updating an attribute in the record identified by the query of the session persistence table, where the query is made to a session persistence table with session attributes grouped by common traits.

摘要： Embodiments are directed towards managing persistence of network traffic using deep packet inspections of network response packets from an application server. In one embodiment, the network packets are associated with SIP messages. A traffic management device (TMD) interposed between client devices and a plurality of application servers receives messages from the client device and/or the application servers. The TMD performs a deep packet inspection to determine if a defined key value pair that includes a session identifier is detected. If so, and the message is from the application server, the session identifier is then mapped to an application server identifier to persistently refer each subsequent inbound packet from a client device having the same session identifier to the application server mapped to the session identifier.

摘要： A capability is provided for statelessly load balancing Transmission Control Protocol (TCP) connections across a set of servers. A load balancer receives a TCP SYN packet from a client, selects a server for a TCP connection for the client, forms a modified TCP SYN packet including an address of the client, and propagates the modified TCP SYN packet toward the server. The server receives the modified TCP SYN packet, forms a TCP SYN+ACK packet including an identifier (e.g., n bits of an address, an n-bit server index based on mapping information of the load balancer, or the like) of the server, and propagates the modified TCP SYN+ACK packet toward the load balancer. The load balancer receives a TCP packet from the client on the TCP connection, determines a server associated with the TCP connection based on information included within the TCP packet, and propagates the TCP packet toward the server.

摘要： An exemplary network gateway is capable of accepting a session-related message having a session identifier field; the network gateway is adapted to extract a host identifier from a value populating the session identifier field and to perform a routing operation for the session-related message using the host identifier. For an exemplary media implementation, processor-executable instructions direct a device to perform actions including: ascertaining a host identifier from a session identifier field of a session message; and routing the session message responsive to the ascertained host identifier. An exemplary apparatus includes: at least one processor; and one or more media including processor-executable instructions that are capable of being executed by the at least one processor to direct the apparatus to perform actions including: receiving a session message having a session identifier including a host identifier; and routing the session message responsive to the host identifier.
