Described embodiments provide systems and methods for inferring a network type and network conditions. The system includes a packet capturing engine configured to capture a plurality of network packets from a plurality of TCP network connections. The system includes a packet analyzer configured to analyze the plurality of network packets to generate a plurality of metrics. The system includes a network classifier configured to infer network types of the plurality of TCP connections based on the plurality of metrics and at least one classification model. The system also includes a conditions ranking engine configured to estimate a level of network congestion for each TCP connection based on the plurality of metrics and the network types.

Inferring radio type from clustering algorithms

Inferring congestion and signal quality

A computer network appliance may include a memory and a processor cooperating with the memory to run a classification kernel module performing traffic shaping on data packets based upon a first set of queuing disciplines (qdiscs). The processor may further run at least one virtual device also performing traffic shaping on the data packets based upon a second set of qdiscs different than the first set of qdiscs, and provide the data packets to a network interface.

Large scale bandwidth management of IP flows using a hierarchy of traffic shaping devices

A network environment includes a client station coupled to a proxy server via a first network and one or more content servers coupled to the proxy server via a second network. A plurality of connections are established between the client station and the proxy server over the first network. Requests are dynamically interleaved over any of the connections to the proxy server by the client station. Content is retrieved for the requests from any of the content servers over the second network by the proxy server. Responses including retrieved content for respective requests are dynamically interleaved over any of the connections by the proxy server to the client station.

Method and system for dynamic interleaving

A cache server includes a memory, and a processor to acquire segments of media data associated with a first request, with the first request being generated by a client device. The segments associated with the first request are stored in the memory. Keys for the segments associated with the first request are generated, with each segment having a respective key associated therewith that is a unique identifier for that segment.

Systems and methods for partial video caching

Described herein are approaches for shaping traffic within a data network. In particular, methods and systems herein describe devices configured to classify packets based on particular criteria. Based on a classification associated with a packet, a packet can be queued at a subscriber mux device, one of a plurality of subscriber devices, and an application device. In addition, the subscriber devices and the application device include qdiscs to shape traffic. Once the traffic is shaped, it is queued based on properties associated with packets.

A cache server, a method, and a non-transitory computer-readable medium storing a set of instructions are disclosed. The apparatus comprises a memory and one or more processors configured to acquire one or more segments of media data associated with a first request, the first request being generated by one or more client devices, store the one or more segments associated with the first request, generate a key for each segment of the one or more segments associated with the first request, and generate a first set entry and a first set key for the one or more segments associated with the first request.

A system and method is provided for controlling multimedia data transmission to a communication device via a network. The system comprises a de-muxer configured to obtain a first multimedia data for transmission and a flow controller configured to evaluate an estimated buffer time associated with the communication device. If the estimated buffer time satisfies a first threshold condition, the flow controller updates a current transmitting state to be a pacing state. And if the estimated buffer time satisfies a second threshold condition, the flow controller updates the current transmitting state to be a bursting state. The system also comprises a muxer configured to transmit the first multimedia data at a transmitting rate corresponding to the bursting state or the pacing state.

Methods and systems for optimal delivery of internet video over wireless networks

A system and method is provided for determining a client device identity. In one implementation, a method is provided that can include receiving a request from a client device. The method can also include determining, based on the client device request, a subscriber identification. After determining the subscriber identification, the method can include acquiring, from a transactional history database, transactional device data associated with the subscriber identification. In some embodiments, the transactional device data can include one or more counts associated with one or more device types. The method can also include determining, based on the transactional device data, the client device identity. In some embodiments, the determination of the client device identity can include selecting a device type of the one or more device types with the maximum count and setting the client device identity to the selected device type.

Systems and methods for detecting device identity at a proxy background

Systems and methods are described for using a client agent operating in a virtual private network environment to intercept HTTP communications. Methods include: intercepting at the network layer, by a client agent executing on a client, an HTTP request from an application executing on the client; modifying the HTTP request; and transmitting, via a transport layer connection, the modified HTTP request to a server. Additional methods may comprise adding, removing, or modifying at least one cookie in the HTTP request. Still other methods may comprise modifying at least one name-value pair contained in the HTTP request. Corresponding systems are also described.

Systems and methods for using an HTTP-aware client agent

Systems and methods for reducing file sizes for files delivered over a network are disclosed. A method comprises receiving a first file comprising sequences of data; creating a hash table having entries corresponding to overlapping sequences of data; receiving a second file comprising sequences of data; comparing each of the sequences of data in the second file to the sequences of data in the hash table to determine sequences of data present in both the first and second files; and creating a third file comprising sequences of data from the second file and representations of locations and lengths of said sequences of data present in both the first and second files.

Systems and methods for enhanced delta compression

An appliance and method for authorizing a level of access of a client to a virtual private network connection, based on a client-side attribute includes the step of establishing, by an appliance, a control connection with a client upon receiving a client request to establish a virtual private network connection with a network. The appliance transmits, via the control connection, a request to the client to evaluate at least one clause of a security string, the at least one clause including an expression associated with a client-side attribute. The client transmits, via the control connection, a response to the appliance comprising a result of evaluating the at least one clause by the client. The appliance assigns the client to an authorization group based on the result of evaluation of the at least one clause.
