A system and method for fault notification in a data communication network. In accordance with the invention, notification of each fault occurring in the network is quickly and efficiently propagated throughout the network. In response, appropriate action can be taken to recover from the fault. Possible points of failure are identified in the network. Indicia of each identified possible point of failure is formed. The indicia of the identified possible points of failure are propagated within the network. The indicia of the identified possible points of failure are stored in network nodes. Whether a fault has occurred in the network is determined. When a fault has occurred, a fault notification is propagated by at least one of the network nodes that detects the fault to its neighboring network nodes. Propagation of the fault notification may include sending the fault notification by a label switched packet. The label switched packet may have a fault information label (FIL) that distinguishes the fault notification from data traffic.

A system and method for providing multiple levels of fault protection in a data communication network. Fault protection criteria for each of a plurality of resources in the network is stored in each of a plurality of nodes of the network. The fault protection criteria includes indicia of a type of fault protection available to the resource. Desired fault protection criteria is determined for a label-switched path between a node of the network that is a source for data and a node of the network that is a destination for the data. A candidate resource in the network for is selected for a communication path between the source and the destination. Whether the candidate resource provides at least the desired level of fault protection is determined from the fault protection criteria. When the candidate resource provides at least the desired level of fault protection, the candidate resource is selected for the communication path. The invention provides an improved technique for managing available types of redundancy to provide a minimum specified amount of fault protection for various data flows without wasting resources, such as by providing excessive redundancy.

A method and apparatus that makes it possible to have a single unified network where the devices at the edge are able to handle both wired and wireless traffic. Separate devices are not required to handle wired and wireless traffic. Instead the whole enterprise network comprises devices that are agnostic to the nature of the traffic and have all the features required by both wired and wireless traffic.

A network device for determining an optimal sampling phase for source synchronous data received on a data communications channel. The network device includes a transmitter clock domain for providing a data pattern along with a synchronous free-running clock. The network device also includes a plurality of phases of a core clock. The network devices further includes means, in a core clock domain, for sampling a data pattern generated by the received clock with the plurality of phases to determine the optimal phase for sampling the data received from the external device.

Systems and methods applicable to a unified wired/wireless network device are proposed to address quality of service issues and roaming support for wired and wireless clients in a unified wired/wireless network. The proposed solution can include a hierarchical scheduler and shaper mechanism that is able to flexibly support different quality of service disciplines, i.e., strict-priority, guaranteed bandwidth, deficit-round-robin, etc., to allow different levels of maximum and minimum bandwidth allocation to each user or group of users. The solution can also include a dynamic queue assignment mechanism that allows queues to be moved from one queue-group and/or port to another queue-group and/or port, without losing packets, when a wireless client roams between access points within the unified network.

A system and method for the fast re-routing of data in a data communication network. A protection label path is formed between a base node and an end node wherein the protection path avoids an intermediate node between the base node and the end node. Availability of protection provided by the protection path is advertised within the network. A protected path is formed for communicating data, the protected path passing through the intermediate node. When a fault is detected in the network, the fault is avoided by using the protection path for communicating data. Thus, alternate paths are defined for bypassing entire network nodes. As such, the protection paths allow data to be re-routed so as to avoid failed network nodes as well as failed network links.
