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

A method and system for load balancing are provided. The method includes: receiving a tunnel frame from a traffic flow; determining whether the tunnel frame is one of a plurality of frames from a packet; if the frame is one of a plurality of frames, reassembling the plurality of frames associated with the packet to determine an inner IP header; load balancing the packet based on the inner IP header; and applying traffic policies to the packet. The system has: a traffic interface configured to receive a tunnel frame from the traffic flow; a subscriber load balancer configured to determine whether the tunnel frame is one of a plurality of frames from a packet; at least one IP reassembly engine configured to reassemble the plurality of frames associated with the packet to determine an inner IP header; and at least one flow policy engine configured to load balance the packet based on the inner IP header; and apply traffic policies to the packet.

System and method for load balancing in computer networks

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.
