摘要： A system and method for electing a master switch includes a management port for coupling a first switch to a management system, a plurality of stacking ports for coupling the first switch to other switches in a stacked switch, and a control unit. The control unit detects one or more first connectivity settings of the management port, exchanges the first connectivity settings with the other switches using at least one of the stacking ports, exchanges second connectivity settings for the other switches using the stacking ports, and elects a master switch for the stacked switch based on the first and second connectivity settings. In some embodiments, the control unit further receives a first management configuration from the management system, exchanges the first management configuration with the other switches, exchanges second management configurations of the other switches, and further elects the master switch based on the first and second management configurations.

摘要： An apparatus and method for extending the scalability and improving the partitionability of networks that contain all-to-all links for transporting packet traffic from a source endpoint to a destination endpoint with low per-endpoint (per-server) cost and a small number of hops. An all-to-all wiring in the baseline topology is decomposed into smaller all-to-all components in which each smaller all-to-all connection is replaced with star topology by using global switches. Stacking multiple copies of the star topology baseline network creates a multi-planed switching topology for transporting packet traffic. Point-to-point unified stacking method using global switch wiring methods connects multiple planes of a baseline topology by using the global switches to create a large network size with a low number of hops, i.e., low network latency. Grouped unified stacking method increases the scalability (network size) of a stacked topology.

摘要： According to an example, a Controlling Bridge (CB) receives a VCF registration request packet sent by a Port Extender (PE) and sets interface state of a VCF interface receiving the VCF registration request packet from initial state to blocked state. The CB returns a VCF registration response packet to the PE and receives a VCF registration acknowledge packet returned by the PE after the PE receives the VCF registration response packet. The CB sets interface state of a VCF interface sending the VCF registration request packet from blocked state to forwarding state; sets interface state of the VCF interface receiving the VCF registration request packet as forwarding state, and establishing successfully a VCF link with the PE.

摘要： This application discloses a packet processing method and an LSR. The method includes: receiving, by an Ingress LSR of a first MPLS tunnel, a first notification packet that is based on an IGP, where the first notification packet includes an ELC flag, which is used to indicate that the first Egress LSR has ELC; after learning from the first notification packet that the first Egress LSR has ELC, inserting a label into a first packet, to generate a second packet, where the label forms an MPLS label stack, which includes, from bottom to top, a first EL, a first ELI, and a first TL; and sending the second packet to the first Egress LSR through the first MPLS tunnel. According to the solutions of this invention, a Transit LSR of the first MPLS tunnel may perform load balancing when forwarding the second packet.

摘要： Various techniques for partitioning a computer network is disclosed herein. In certain embodiments, control plane functions (e.g., computation of network routes) and/or forwarding plane functions (e.g., routing, forwarding, switching) may be partitioned and performed individually on per domain basis based on (1) a network configuration of a particular domain (e.g., end points and/or lower-level domains in the particular domain); and (2) one or more higher-level domains connected to the particular domain in the hierarchy. Thus, a particular domain can manage various network operations of the domain without concerns regarding end points or network nodes in other domains of the hierarchy. Thus, network configuration and operation may be partitioned to reduce hardware costs and operational complexity even as the size of the overall computer networks increases.
摘要翻译：本文公开了用于划分计算机网络的各种技术。在某些实施例中，可以基于（1）网络配置来对每个域分别执行控制平面功能（例如，网络路由的计算）和/或转发平面功能（例如，路由，转发，交换）特定域（例如，特定域中的端点和/或较低级域）; 和（2）连接到层次结构中的特定域的一个或多个更高级别的域。因此，特定的域可以管理域的各种网络操作，而不考虑层级结构的其他域中的端点或网络节点。因此，即使整个计算机网络的大小增加，也可以对网络配置和操作进行分区以降低硬件成本和操作复杂性。

摘要： A first processor assigns switches and/or switch ports to a virtual stack according to configuration information and stores the virtual topography of the virtual stack in a mapping table. The mapping table correlates switches, switch ports, computer processors, and virtual stacks. The first processor receives a data unit from a first switch that includes a source address and a destination address. The destination address identifies a switch and switch port. The first processor compares the destination address to the mapping table to determine a second computer processor and sends the data unit to the second computer processor, the second computer processor corresponding to a switch and/or switch port identified in the destination address of the data unit.
