摘要： In general, techniques are described for reducing response times to retrieve content in an intermediate network device. In particular, the intermediate network device receives a packet from a client device of a first network that requests content from a remote network device of a second network, inspects the packet to determine whether the requested content has been previously cached to either of a first and a second memory of the device, issues a request to load the requested content from the second memory to the first memory based on the determination and queues the packet within in the queue. After queuing the packet, the intermediate network device then processes the packet to assemble a response that includes the content from the memory.

摘要： A method includes receiving a data unit, determining whether a current state, associated with a deterministic finite automata (DFA) that includes a portion of states in a bitmap and a remaining portion of states in a DFA table, is a bitmap state or not, and determining whether a value corresponding to the data unit is greater than a threshold value, when it is determined that the current state is not a bitmap state. The method further includes determining whether the current state is insensitive, when it is determined that the value corresponding to the data unit is greater than the threshold value, where insensitive means that each next state is a same state for the current state, and selecting a default state, as a next state for the current, when it is determined that the current state is insensitive.

摘要： In general, techniques are described for efficiently implementing application identification within network devices. In particular, a network device includes a control unit that stores data defining a group Deterministic Finite Automata (DFA) and an individual DFA. The group DFA is formed by merging non-explosive DFAs generated from corresponding non-explosive regular expressions (regexs) and fingerprint DFAs (f-DFAs) generated from signature fingerprints extracted from explosive regexs. The non-explosive regexs comprise regexs determined not to cause state explosion during generation of the group DFA, the signature fingerprints comprise segments of explosive regexs that uniquely identifies the explosive regexs, and the explosive regexs comprise regexs determined to cause state explosion during generation of the group DFA. The network device includes an interface that receives a packet and the control unit traverses first the group DFA and then, in some instances, the individual DFAs to more efficiently identify network applications to which packets correspond.

摘要： In general, the invention is directed to techniques of dynamically balancing network traffic load among multiple paths through a computer network. The techniques distribute and redistribute flows of network packets between different paths based on dynamically measured path bandwidth and loads of each flow. In distributing the flows, Quality of Service (QoS) bandwidth requirements of the flows may be maintained.

摘要： A data communication system 10 is provided that allow for the efficient management of data communication sessions requested from a plurality of packet data servicing nodes (22-28) which are organized in a cluster 32, each member of the cluster 32 manages a cluster session table which contains data identifying mobile units 12 and packet data servicing nodes (22-28) which are servicing data sessions with the mobile unit 12. As a mobile unit 12 moves from one portion of the system 10 to another, a network element such as a base station controller 40 will request a data session from a packet data servicing node 28, the packet data servicing node 28 is then able to access the cluster session table to determine if the data session is already being served by another member of the cluster 32. If the data session is already in existence, the base station controller 40 will be directed to request a data session from the packet data servicing node 32 which is already servicing that session. In this manner, the hand off of data communication sessions between packet data servicing nodes is reduced or eliminated.
