摘要： Differentiated services for network traffic using weighted quality of service is provided. Network traffic is queued into separate per flow queues, and traffic is scheduled from the per flow queues into a group queue. Congestion management is performed on traffic in the group queue. Traffic is marked with priority values, and congestion management is performed based on the priority values. For example, traffic can be marked as "in contract" if it is within a contractual limit, and marked as "out of contract" if it is not within the contractual limit. Marking can also include classifying incoming traffic based on Differentiated Service Code Point. Higher priority traffic can be scheduled from the per flow queues in a strict priority over lower priority traffic. The lower priority traffic can be scheduled in a round robin manner.

摘要： A method or corresponding apparatus in an exemplary embodiment of the present invention determines how many copies of a multicast packet are to be sent, as copies, to multiple destinations based on information in the multicast packet and a group (e.g., bridge node) with which the packet is associated. The copies of the multicast packets are then generated. After generating the copies, an action to take for each copy is determined. This determination is made using the information in the multicast packet and based on the group with which the packet is associated. After the action is determined for each copy, the action is performed on each copy. Through use of an embodiment of the present invention, memory space is conserved, allowing for continued use of a device in a multicast environment of an ever growing network, such as the Internet.

摘要： A device having circuit bundles and a method of configuring the network device to provide resiliency and protection for network circuits. A circuit bundle provides the ability to group multiple circuits of the same type for resiliency/protection. There is an active virtual circuit that is selected based on a user configured priority value defining priority for carrying circuit traffic. When the active virtual circuit fails, alternative virtual circuits are selected to carry the circuit traffic, again based on user configured priority. Virtual circuits included in the circuit bundle can have different destinations, and include at least multipoint virtual circuits.

摘要： A network layout between network elements and routers using network redundancy to improve reliability of network communication is disclosed. Upon detecting a link failure associated with a primary link between an access switch and a primary router by the access switch via a connectivity verification protocol, the access switch sends a message to the primary router indicating connection defect via the connectivity verification protocol such as IEEE 802.1 ag standard. After enabling protection switching mechanism to activate a secondary link between the access switch and a backup router for network communication, routing data streams are routed between the access switch and the router via the secondary link. In one aspect, the protection switching mechanism is operated in accordance with G.8031 under International Telecommunication Union (“ITU”) standard.

摘要： An apparatus and a method for enhancing digital processing implementation using non-power-of-two even count Gray coding are disclosed. The even count encoding device includes a first circuit, a second circuit, and a coding circuit. The first circuit, in one embodiment, is configured to identify a first portion of entries in a table in response to an input number. The second circuit is capable of determining a second portion of entries in the table in response to the input number, wherein the number of the first portion of entries and the number of the second portion of the entries are substantially the same. The coding circuit is operable to concatenate the second portion of the entries to the first portion of the entries to form an output table, which includes a sequence of even count integers wherein the difference between two adjacent integers is one bit position.

摘要： An exemplary method for circuit emulation over a multi-packet label switching (MPLS) network comprises the steps of receiving a time division multiplexed data stream at an ingress end, dividing the data stream into a set of fixed sized packets, adding a service header to each of the packets, adding an additional header on top of the service header in accordance with MPLS protocols, removing the additional header after each packet has been processed by the MPLS network, and using the service header to recover the data stream at an egress end.

摘要： Embodiments of the present invention relate to portions of a switch fabric having a single logical stage and at least one physical stage. In addition, the data paths and the control paths of the switch fabric can be decoupled thereby allowing additional processing to be performed than would otherwise be the case with control rates that matched the high data rates. In other words, data cells received on high speed links can be spread over many lower speed links; consequently, the data cells can transit the switch fabric at that high speed while the control information associated with the data can be processed at that lower speed. Because the control information can be processed at a lower speed (associated with the control path), the control information can be processed over a greater period of time.
摘要翻译：本发明的实施例涉及具有单个逻辑级和至少一个物理级的交换结构的部分。此外，交换结构的数据路径和控制路径可以去耦合，从而允许执行额外的处理，否则与匹配高数据速率的控制速率的情况相反。换句话说，在高速链路上接收的数据信元可以分散在许多低速链路上; 因此，数据单元可以以高速度传送交换结构，同时可以以较低的速度处理与数据相关联的控制信息。由于可以以较低的速度（与控制路径相关联）来处理控制信息，所以可以在更长的时间段内处理控制信息。
