A system for steering network traffic to service functions in a service function chain, the system including: a processor; a data storage module; an input interface; an output interface; a classifier configured to determine a path for a data packet in the service function chain; and a forwarder configured to determine the next location to which the data packet will be sent based on the path. A method for steering network traffic to service functions in a service function chain, the method including: classifying a data packet to determine a path for a data packet in the service function chain; and forwarding the data packet to a next location to which the data packet will be sent based on the path.

System and method for traffic steering and analysis

There is provided a system and method for diverting established communication sessions, which includes: receiving at least one packet from a communication session; determining the state of the communication session; if the state of the communication session is diverted, bridging the at least one packet to a service chain; if the state of the communication session has been prohibited from being diverted, forwarding the at least one packet to an endpoint; and otherwise, if the state of the communication session is a state prior to the divert decision, saving the at least one packet and determining whether the communication session is a candidate to be diverted to the service chain.

System and method for diverting established communication sessions

The present invention is related to a system and method for examining a communication stream between two nodes for a protocol of interest. If a protocol of interest is found, the communication stream is diverted to a divert host. If a protocol of interest is not found, the stream passes without diversion. By way of example, the invention is shown to work with TCP and UDP.

System and method for diverting established communication sessions on the basis of content

A system and method for subscriber aware network monitoring is provided. The method includes: determining subscriber and session data, wherein the subscriber has a non-unique IP (Internet Protocol) address; retrieving identifying data from a packet; and comparing the identifying data with the determined subscriber and session data to determine the subscriber associated with the packet. The system includes: at least one network probe configured to determine subscriber and session data, wherein the subscriber has a non-unique Internet Protocol (IP) address; at least one traffic probe configured to retrieve identifying data from a packet; and a processing module configured to compare the identifying data with the stored subscriber and session data to determine the subscriber associated with the packet.

System and method for subscriber aware network monitoring

The present disclosure provides a system and a method for managing network traffic. The traffic management system has a quality of experience (QoE) measurement module configured to monitor a QoE metric in real-time. A control module is configured to periodically receive the QoE metric and determine a traffic management action based on the QoE metric. A traffic management module is configured to apply the traffic management action to the network traffic.

Systems and methods for traffic management

A system and method for automatically configuring a network so that each switch in the network is aware of the Multiple Spanning Tree Instances (MSTI) of each other switch and the Virtual Local Area Network (VLAN) that each switch uses. This is achieved through the use of controllers connected to each switch. A master switch is elected and the master switch monitors messages to determine if a switch should be using an alternative MISTI. If so, the master switch instructs a switch to use an alternative MSTI. Either a switch or a node connected to the switch may determine which VLAN to use in sending messages, subject to configuration from the controller of the master switch. Messages are periodically sent by each controller to educate other controllers to aid in learning which node is part of a group connected to a switch, the switch in turn connected to a controller.

Automatically maximizing network link utilization using virtual networks

A computer based system and method for distributing a global shaper rate implemented across multiple traffic processing devices. A controller distributes credits according to the demand (amount of traffic, or offered load) of each device, in such a way to achieve global targets, including the shaper rate, strict prioritization of traffic, WFQ weights and fairness between cloned channels, iteratively updated as changes occur in the quantity and makeup of the traffic across the devices.

Method and apparatus for distributing credits to multiple shapers to enable shaping traffic targets in packet communication networks

The present invention discloses how a transcoder may be used to reduce the bit rate of an MPEG-2 stream by transmitting only the visible area of the movie specified by pan-scan directives. Because the pan-scan conversion is performed prior to transmission, not immediately before display, the non-viewed portion of video does not need to be transmitted.

System and method for improving transrating of MPEG-2 video

The invention disclosed is a Transmission Control Protocol (TCP) transport handler for a network intermediary. The handler examines all segments in a TCP/IP data stream between two nodes The handler maintains a list of changes made by an application module to a data segment within a data stream and utilizes that list to ensure that the sequence numbers for both receiver and transmitter refer to the same segments of data. The list of changes is also used to reapply changes to retransmitted packets. Data segments are not acknowledged until the receiver acknowledges a segment, eliminating the requirement of buffering data segments.
