摘要： Network switches may be configured using flow tables. Flow table entries may contain header fields and associated actions. When a packet is received by a network switch, the network switch can compare fields in the packet to fields in the flow table entries and can take corresponding actions when matches are detected. A controller server can determine the topology of a network and can gather information on the capacities of network switches and other network switch capabilities. Based on this information and network configuration rules, the controller server can generate flow tables for the network switches that direct the switches to forward packets along desired paths through the network. The flow table entries for switches that are nearer the network core can be provided with more wildcarding than switches nearer the network edge. Traffic can be forwarded through encapsulation and deencapsulation engines to allow tunneling between isolated network domains.
摘要翻译：网络交换机可以使用流表配置。流表条目可能包含头字段和相关联的动作。当网络交换机收到数据包时，网络交换机可以将数据包中的字段与流表项中的字段进行比较，并在检测到匹配时采取相应的动作。控制器服务器可以确定网络的拓扑结构，并可以收集关于网络交换机的容量和其他网络交换机功能的信息。基于该信息和网络配置规则，控制器服务器可以为网络交换机生成流表，以指示交换机通过网络沿着所需路径转发数据包。更接近网络核心的交换机的流表条目可以比靠近网络边缘的交换机提供更多的通配符。流量可以通过封装和解封装引擎转发，以允许在隔离网络域之间进行隧道传输。

摘要： A network node or corresponding method of performing link aggregation reduces a number of Content Addressable Memory (CAM) entries required to make a forwarding decision for a given ingress flow, reducing cost, size, and power consumption of the CAM and accompanying static RAM. In one embodiment, an ingress flow is mapped to an egress flow identifier. Subsequently, the egress flow identifier is mapped to a member of an aggregated group associated with an egress interface based on information available in a given ingress flow. Finally, the given ingress flow is forwarded to the member of the aggregated group associated with the egress interface. A hashing technique or two lookups may be used alone or in combination in mapping the ingress flow to the egress flow identifier to reduce CAM memory usage.

摘要： A network relay device capable of shortening retrieval time for an address table or reducing a capacity of the address table is provided. When a transmission-source address of a frame received at first and second port groups is learned, a frame processing unit performs a hash calculation by using the transmission-source address and a first internal identifier 0.1. Then, an internal identifier etc., corresponding to the receiving port is registered in an entry inside an address table obtained by the hash calculation. On the other hand, when a transmission-destination address of a frame received at the first and second pot groups is retrieved, the frame processing unit performs a hash calculation by using the transmission-destination address and 0.1, reads out an entry inside the address table obtained by the hash calculation, and compares the internal identifier inside the address table with an internal identifier corresponding to the receiving port.

摘要： A console is provided and includes a switch and a network device. The network device includes a switch port, first network ports, and a controller. The switch is separate from the network device. Each of the first network ports receives a frame of data, and inserts source information into the frame of data. The source information in each frame of data identifies the first network port that received the frame of data. The controller transfers each frame of data, including the source information, to the switch via the switch port. The switch: adds to each frame of data, destination information identifying one or more of the first network ports; and transfers each frame of data, including the source and destination information, to the switch port. The controller transfers each frame of data, received from the switch port, to the first network ports.

摘要： An input/output (I/O) switch fabric includes input physical ports that convey packets associated with at least a first network flow. Moreover, virtual routers in the I/O switch fabric, which have associated routing tables, provide types of service and/or routes for different source-destination pairs based on link-layer information and network-layer information in the packets. Note that different virtual routers can provide different types of service and/or different routes. For example, a type of service associated with a first virtual router may include changing packet headers when crossing service domains in a global network, and a type of service associated with a second virtual router may avoid changing packet headers when providing connectivity in the network. Furthermore, the I/O switch fabric includes output physical ports that convey packets associated with at least a second network flow. The virtual routers may facilitate InfiniBand inter-subnet crossing.
摘要翻译：输入/输出（I / O）交换结构包括传送与至少第一网络流相关联的分组的输入物理端口。此外，具有关联路由表的I / O交换结构中的虚拟路由器基于分组中的链路层信息和网络层信息，为不同的源 - 目的地对提供类型的服务和/或路由。注意，不同的虚拟路由器可以提供不同类型的服务和/或不同的路由。例如，与第一虚拟路由器相关联的一种服务可以包括在跨越全局网络中的服务域时改变分组报头，并且与第二虚拟路由器相关联的服务类型可以避免在网络中提供连接时改变分组报头。此外，I / O交换结构包括传送与至少第二网络流相关联的分组的输出物理端口。虚拟路由器可能有助于InfiniBand跨子网跨越。
