摘要： A method is described for sending frames of data from at least two sending nodes via one or more forwarding nodes to one receiving node in an ATM network. Each frame of data is partitioned into cells and includes a VPI field and a VCI field. The sending nodes include a first label into the VPI field of each of the cells representing an identification of the routing of the cell. Furthermore, the sending nodes include a second label into the VCI field of each of the cells representing an identification of the source of the cell. The forwarding node swaps the first and the second label according to a swapping table. With respect to the second label, the forwarding node enters the swapping table in the column of the output labels and reads the corresponding input label.

摘要： A method and system for data traffic management in telecommunications networks is presented. End user data streams are aggregated to achieve more efficient use of a communication channel. Bandwidth is dynamically allocated to the data streams of the various users, effectively reducing their communications costs. The system includes a class of service selector and a plurality of stream selectors. Each stream selector is associated with a single budget category. Data is placed into queues according to a priority assigned by the end user. Data packets are transmitted from their queues through the class of service selector and through one of the stream selectors in response to the traffic provided by the end users and the budget category subscriptions of the end users.

摘要： Efficient protection mechanisms for ring based label-switching networks are designed to protect point-to-point label switching paths (LSPs) while preventing misconnection and mismerge situations. The protection switching is performed by nodes adjacent to the point of failure. The switching decision is based on a locally detected signal fail condition. The operation of the protection mechanisms does not require the use of any protection switching protocol. In one embodiment of the present invention, the protection is achieved by assigning an exclusive label to each LSP. In another embodiment, the protection is achieved by providing a closed-loop protection tunnel and assigning a tunnel label for each such protection tunnel. In yet another embodiment, the protection is achieved by establishing a mirror path for each protected LSP.

摘要： Efficient protection mechanisms for ring-based label-switching networks, such as multi-protocol label switching (MPLS) networks. The protection mechanisms are designed to protect point-to-multipoint label switching paths (LSPs). In steering ring protection embodiments, the nodes of the ring network are provided with pre-configured tables that enable each node to operate in both working mode and protection mode. The information required for each node to switch between the two modes in included in its respective table during the pre-configuration of the ring network. In wrapping ring protection embodiments, the wrapping is performed by assigning a unique LSP label to each LSP and further configuring each intermediate node in the ring network to transparently pass data packets including the unique LSP label. Upon detecting a failure in a network node, the data packets including the unique LSP label are switched to a protection ring.
