摘要： The invention integrates a plurality of separate stack switches into a unified system of switches under a common configuration and management architecture. The switches, preferably stack switches, may be distributed throughout a local area network (LAN) and need not be co-located. One preferred embodiment supports fail-safe operations to minimize the disruption caused when a stack switch becomes inoperative. In another preferred embodiment, the stack switches are enabled with a system-wide address table and quality of service mapping matrix with which each switch can effectively provision system bandwidth.

摘要： A stack switch for performing pass-through forwarding operations, assigning stack switch identifiers to a plurality of stack switches, temporarily disabling supervision messages exchanged by stack switches, and electing a primary master stack switch is disclosed. In the pass-through mode, the stack switch automatically forwards packets between stack ports independent of their destination address to maintain connectivity between adjacent stack switches while conventional bridging and routing operations are disabled. The sequential identifiers are also preferably assigned in accordance with the sequential position of the various stack switches to better reflect the topology of those switches. The switch is also preferably adapted to temporarily disable the transmission of supervision messages between stack switches to prevent re-assignment of network management functions when switch resources are low. The switch may execute a stack switch identifier numbering scheme based on the time the switch became operational.
摘要翻译：公开了一种用于执行传递转发操作的堆叠交换机，向多个堆叠交换机分配堆叠交换机标识符，临时禁用由堆叠交换机交换的监督消息，以及选择主主堆栈交换机。在直通模式下，堆叠交换机自动在堆栈端口之间自动转发数据包，而不依赖于目标地址，以保持相邻堆叠交换机之间的连通性，而传统的桥接和路由操作被禁用。顺序标识符还优选地根据各种堆叠交换机的顺序位置来分配，以更好地反映那些交换机的拓扑。交换机还优选地适于暂时禁用堆叠交换机之间的监督消息的传输，以防止当交换机资源较低时重新分配网络管理功能。交换机可以根据交换机的运行时间执行堆叠交换机标识符编号方案。

摘要： Aspects for processing data in a server may include receiving a packet and determining a function associated with the packet. A blade server handling the function associated with the packet may be determined and the packet may be steered to that blade server. At least one association may be generated or created between a particular characteristic of a packet and a particular function associated with that packet. At least one blade server may be assigned to handle the particular function associated with a packet. The particular characteristic of the packet may include, for example, a packet type, a field within the packet and/or a flag within a portion of the packet. Steered packets may be processed by one or more blade servers that may be adapted to handle the function associated with the packets. A switch blade may be utilized to control steering of the received packets.

摘要： Methods and systems for routing messages between a mated pair of routing nodes with a distributed processing architecture and one or more redundantly connected remote applications are disclosed. A mated pair of routing nodes uses private point codes to distribute messages destined for remote applications among internal processing modules and between the routing nodes. The routing nodes replace the private point codes with a shared point code before sending the messages to one of the remote applications. When communicating with external PSTN nodes, the mated pair of routing nodes uses the shared point code.

摘要： A router with a routing layer that supports single or multiple routing protocols. The routing layer has at least two routing protocol computing entities, namely a first and a second routing protocol computing entities. Each routing protocol computing entity includes a CPU, a data storage medium in communication with the CPU and a program data stored in the data storage medium for execution by said CPU. The program data in each routing protocol computing entity implements different or the same routing protocols. This routing layer architecture is highly scalable.

摘要： Router line cards are partitioned, separating packet forwarding from external or internal interfaces and enabling multiple line cards to access any set of external or internal data paths. Any failed working line card can be switchably replaced by another line card. In particular, a serial bus structure on the interface side interconnects any interface port within a protection group with a protect line card for that group. Incremental capacity allows the protect line card to perform packet forward functions. Logical mapping of line card addressing and identification provides locally managed protection switching of a line card that is transparent to other router line cards and to all peer routers. One-for-N protection ratios, where N is some integer greater than two, can be achieved economically, yet provide sufficient capacity with acceptable protection switch time under 100 milliseconds. Alternatively, protect line cards can routinely carry low priority traffic that is interruptible, allowing the protect line card to handle higher priority traffic previously carried by a failed working line card. This approach renders unnecessary engineering a network for less than full capacity to allow rerouting in the event of individual line card failure. Consequently, all data paths can be fully utilized. If a particular interface module on one data bus needs removal for maintenance, a duplicate data bus is available intact, allowing hot replacement of any working or protect interface module, even while a line card protection switch is in effect.
