Abstract: In one embodiment, a list of source identifiers is maintained at a virtual switch. These source identifiers are allowed to send packets through the virtual switch to ports in a private virtual local area network (PVLAN). When a packet is received at the virtual switch from a particular source destined for a particular port in the PVLAN, the virtual switch determines whether a particular identifier associated with the particular source matches one of the source identifiers in the list. If that particular source identifier is not on the list, the packet is prevented from being forwarded to the particular port in the PVLAN.
Abstract translation: 在一个实施例中，在虚拟交换机上维护源标识符的列表。 允许这些源标识符通过虚拟交换机发送到私有虚拟局域网（PVLAN）中的端口。 当虚拟交换机从虚拟交换机接收目的地为PVLAN中的特定端口的分组时，虚拟交换机确定与特定源相关联的特定标识符是否与列表中的一个源标识符匹配。 如果该特定源标识符不在列表中，则阻止该数据包转发到PVLAN中的特定端口。

Abstract: A blade switch for increased interface scalability is provided. The blade switch may address interface scalability by having each of the switch linecards manage its interfaces locally and may use the concept of virtual and local interfaces for intelligent forwarding. The blade switch may appear as a single network switch having a single bridge ID from the network perspective during operation and from the customer perspective during configuration.
Abstract translation: 提供了一种用于增加接口可扩展性的刀片式交换机。 刀片交换机可以通过使每个交换机线路卡在本地管理其接口来解决接口可扩展性，并且可以使用虚拟和本地接口的概念进行智能转发。 在操作期间，刀片交换机可以从网络的角度出发，具有单个桥接ID，并且在配置期间从客户的角度出发。

Abstract: A method is disclosed for performing message payload processing functions in a network element on behalf of an application. According to one aspect, a network element intercepts data packets comprising network layer or transport layer headers having an address of a destination which destination differs from the network element. The network element determines whether information contained in layer 2-4 headers of the data packet satisfies specified criteria. If the information satisfies the specified criteria, the network element directs the data packets to a blade of the network element that performs processing based on an application layer message at least partially contained in the data packets. If the information does not satisfy the specified criteria, the network element forwards the data packets towards the destination without sending them to the blade.
Abstract translation: 公开了一种代表应用程序在网络元件中执行消息有效载荷处理功能的方法。 根据一个方面，网络元件拦截包括网络层或传输层报头的数据分组，其具有目的地与网络元素不同的目的地地址。 网元确定包含在数据包的第2-4层头中的信息是否满足指定的标准。 如果信息满足指定的标准，则网络元件将数据分组引导到基于至少部分地包含在数据分组中的应用层消息执行处理的网元的叶片。 如果信息不符合规定的标准，则网络单元将数据包转发到目的地，而不将其发送到刀片。

Abstract: In one embodiment, an apparatus can include a service broker configured to: (i) register a service classifier, and to provide context information to the service classifier; and (ii) register a plurality of service nodes. The service broker can also receive capability and service requests from the service classifier. Further, the context information can include a service header, a reachability indication, and an encapsulation, where the service header and the encapsulation may be attached or related to a packet in the service classifier. In addition, the service classifier can use this information to redirect the packet to a first service node.
