摘要： Layer-7 application layer message (“message”) classification is disclosed. A network traffic management device (“NTMD”) receives incoming messages over a first TCP/IP connection from a first network for transmission to a second network. Before transmitting the incoming messages onto the second network, however, the NTMD classifies the incoming messages according to some criteria, such as by assigning one or more priorities to the messages. The NTMD transmits the classified messages in the order of their message classification. Where the classification is priority based, first priority messages are transmitted over second priority messages, and so forth, for example.

摘要： A method, computer readable medium, and system for implementing adaptive forward error correction in a network includes converting at a first computing device a number K of original data packets into a number N of error correction packets for forward error correction for a transmission to a second computing device. A subset number S1 of the number N of the error correction packets which is less than the number N of error correction packets is determined at the first computing device based on a loss rate for the transmission to the second computing device. The determined subset number S1 of the number N of the error correction packets is transmitted from the first computing device to the second computing device.

摘要： A method, computer readable, and apparatus for read-ahead prediction of subsequent requests to send data between a client coupled to a server via a network includes receiving at a traffic management device a request for a part of at least one of a data file and metadata. The traffic management device selects from two or more of a sequential prediction engine, an expert prediction engine and a learning prediction engine to predict a read-ahead of the at least one of the data file and metadata. One or more additional read-ahead parts of the at least one of the data file and metadata are determined with the traffic management device based on the selecting.

摘要： A method, system, machine-readable storage medium, and apparatus are directed towards upgrading a cluster by bifurcating the cluster into two virtual clusters, an “old” virtual cluster (old active cluster) and a “new” virtual cluster (new standby cluster), and iteratively upgrading members of the old cluster while moving them into the new cluster. While members are added to the new cluster, existing connections and new connections are seamlessly processed by the old cluster. Optionally, state mirroring occurs between the old cluster and the new cluster once the number of members of the old and new clusters are approximately equal. Once a threshold number of members have been transferred to the new cluster, control and processing may be taken over by the new cluster. Transfer of control from the old cluster to the new cluster may be performed by failing over connectivity from the old cluster to the new cluster.

摘要： A method, computer readable medium, and device that manages traffic in a multi-service environment including determining a self score for a front virtual service which is coupled to one or more inner virtual services. An aggregate score for the front virtual service is determined based on an aggregate score for each of the one or more inner virtual services and a number of connections between each of the one or more inner virtual services and the front virtual service. An advertised score for the front virtual service for load balancing is obtained based on the determined self score and the determined aggregate score.

摘要： A system, medium and method of automatically discovering a wide area network optimized route is disclosed. A client request is received at a second optimization device to access a server. The second optimization device is of a second local area network with respect to a wide area network (WAN) and is configured to communicate with the server. A probe request is received at the second optimization device from a first optimization device of a first local area network. The probe request establishes an optimization route with the first optimization device. A probe response is sent to the first optimization device, wherein the probe response provides identifying information of the second optimization device. A paired relationship is established, wherein configuration information of the first and second optimization devices are exchanged. An optimization route based on the configuration information is exchanged between the paired first and second optimization devices.

摘要： A system and method for improving TCP performance in a L2 tunneling environment by snooping TCP/IP packets from the tunnel interface, terminating TCP locally and proxying TCP data in separate TCP connections. In particular, the system and method detects an encapsulated outgoing packet utilizing a Layer 2 tunneling protocol, processes a Point to Point Protocol layer in the outgoing packet to establishing Layer 2 tunneling protocol for a connection. The system and method also removes the Point to Point Protocol layer from the outgoing packet and inspects the outgoing packet for TCP information in the packet. The system and method forwards the outgoing packet to a locally driven application protocol path if TCP information is present, wherein the outgoing packet is encapsulated in association with the application protocol path.
