摘要： Provided are a computer program product, system, and method for updating zone information in a distributed switch of data forwarders. For each data forwarder, a sequence number is maintained for zone distribution messages sent to the data forwarder. A change to the ports in the network is detected comprising at least one of an allocation or deallocation of at least one port in the network. The sequence number for each data forwarder is incremented in response to detecting the change. For each data forwarder, a zone distribution message is generated indicating the at least one port allocated and/or deallocated, port information indicating each port in the network that may communicate with each other port, and the sequence number for the data forwarder. The generated zone distribution message is transmitted for each data forwarder to the data forwarder for which the zone distribution message was added.

摘要： Provided are methods and apparatus that enforce zoning rules by separately employing source and destination information. In certain embodiments, information uniquely identifying network destinations is provided on a destination CAM. In these embodiments, each destination identified in the destination CAM has an associated zoning decision vector provided in a results memory. The vector provides specific zoning decisions (permit or deny transmission) for specific sources on the network. The specific zoning decision to be applied to a frame under consideration is selected from a zoning decision vector by using source information taken from the frame.
摘要翻译： 提供通过单独采用源和目的地信息来执行分区规则的方法和装置。 在某些实施例中，在目的地CAM上提供唯一地标识网络目的地的信息。 在这些实施例中，在目的地CAM中标识的每个目的地具有提供在结果存储器中的相关联的分区决定向量。 该向量为网络上的特定源提供特定的分区决定（允许或拒绝传输）。 通过使用从帧获取的源信息，从分区判定向量中选择要应用于正在考虑的帧的具体分区决定。

摘要： Methods and apparatus are provided for improving the configuration, management, and distribution of quality of service information in a fibre channel fabric using zoning mechanisms. Configuration of Quality of Service (QoS) information is made easy by using zones as a classifier for flows. QoS information is included in zone objects, thereby using the existing zone distribution mechanism to distribute QoS information. Devices not part of any zones are placed automatically in the default zone with a default QoS priority level. QoS information for a particular packet is available as soon as the zoning information is obtained.

摘要： Embodiments of the present invention are related to a device and a method for more efficiently processing Ethernet communications that include FCOE communications. In some embodiments the device is a single device including a combination of an aggregator, a filter and a gateway. Such a combination can be more practical, affordable and efficient than the usual arrangement of a several separate devices. In other embodiments, the device of the present invention can be a combination of a switch and a gateway. In yet other embodiments other types of devices can be used. More generally, embodiments of the present invention can apply to a device or method for processing communications involving a set of two network protocols (first and second protocols) as well as a third protocol, the third protocol being compatible with the first protocol and used to define how to tunnel the second protocol over the first protocol.
