摘要： A method, computer readable medium, and apparatus for managing server resources includes receiving at a traffic management device one or more requests in a message based protocol. The traffic management device determines a difference between a level of utilization of resources maintained by a server that handles the one or more received requests and a threshold level of utilization of resources that can be maintained by the server; and randomly delays the one or more requests based upon the determined difference.

摘要： A system, machine readable medium and method for utilizing protocol conversions in policy changing enforcement is disclosed. A message, in a first protocol, is received from a network gateway device including identifying information unique to a client attempting to access a resource from a server. The message is processed using one or more portions of the client identifying information as a unique key identifier. A policy access request is generated, in a second protocol, and includes at least the unique key identifier. The policy access request is sent to a policy server, wherein the policy server is configured to provide policy enforcement information of the client associated with the policy access request. The policy enforcement information is received and one or more policies from the policy enforcement information are enforced to network traffic between the client and the server.

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 method, computer readable medium, and device for dynamic DNS implementation, comprises receiving, at a network traffic management device, a first DNS response from a DNS server, wherein the first DNS response is compliant with Internet Protocol version 4 (IPv4). The first DNS response corresponds to a first DNS request from a client device being compliant with Internet Protocol version 6 (IPv6). The first DNS response is converted into a DNS second response that is compliant with IPv6, by attaching a prefix that identifies a network gateway device which is to handle receive subsequent non-DNS requests from the client device. The second DNS response is routed to the client device. Subsequent non-DNS requests from the client device that contain at least a part of the prefix allow the network traffic management device to route the non-DNS request through the designated network gateway device.

摘要： A system and method for message based load balancing comprises receiving, at a network traffic management device, an encapsulated request from a client device to a destination server for an established session. The request is encapsulated in accordance with a first connection-oriented protocol. The encapsulated message is segmented into a plurality of encapsulated data segments in accordance with a message boundary parameter. Identifying information of a first payload data packet of a first TCP encapsulated data segment is extracted and the first payload data packet is converted into a first connection-less protocol datagram. A message-based load balancing decision is performed on the datagram to assign the datagram to a first server. The first connection-less protocol datagram is converted into a first encapsulated data packet in accordance with a second connection-oriented protocol and is sent from a first virtual server to the first server based on the message-based load balancing decision.
