    • Techniques are described for supporting end-to-end resource reservation protocols, such as the Resource Reservation Setup Protocol (RSVP), using Multi-protocol Label Switching (MPLS). A routing device, such as an edge router coupling a local network to another network, aggregates packet flow reservation requests, and maps the resource requests to Labeled Switch Paths (LSPs) capable of supporting the requested resources. Requests having common forwarding equivalence classes may be aggregated to flow through a single LSP having resources, such as bandwidth, capable of supporting the requests. Routers and other devices within the network need not monitor and support state information associated with the individual end-to-end packet flows. A method, for example, includes mapping requests for end-to-end packet flows through a network to LSPs within the network, and forwarding packets associated with the end-to-end packet flows along the LSPs based on the mapping.
    • 描述了用于支持端到端资源预留协议的技术,例如使用多协议标签交换(MPLS)的资源预留设置协议(RSVP)。 诸如将本地网络耦合到另一网络的边缘路由器的路由设备聚合分组流预留请求,并将资源请求映射到能够支持所请求资源的标签交换路径(LSP)。 具有公共转发等价类的请求可以被聚合以流过具有能够支持请求的诸如带宽的资源的单个LSP。 网络中的路由器和其他设备不需要监视和支持与单个端到端分组流相关联的状态信息。 例如,一种方法包括将网络中的端到端分组流的请求映射到网络内的LSP,并且基于该映射,沿着LSP转发与端到端分组相关联的分组流。

    • A technique for facilitating the management of a wireless database related to station records and radio-frequency (RF) information by reducing unnecessary sharing of the data among wireless switches, thus enhancing efficiency in a wireless network. A system constructed according to the technique includes a collection of wireless switches with each switch having associated access points (AP), an AP database distributed throughout the collection of wireless switches, and at least one station radio frequency (RF) database. The AP database includes data associated with ownership of the AP's by the switches, and the station RF database includes wireless station information and RF information. AP radio adjacency is determined by whether an AP owned by a specific switch can detect the other AP owned by another switch. The station and RF information database is shared only within the subset of switches that have AP radio adjacency.
    • 一种通过减少无线交换机之间数据的不必要共享来促进与台站记录和射频(RF)信息有关的无线数据库管理的技术,从而提高无线网络的效率。 根据该技术构造的系统包括无线交换机的集合,每个交换机具有相关联的接入点(AP),分布在整个无线交换机集合中的AP数据库以及至少一个站射频(RF)数据库。 AP数据库包括由交换机与AP的所有权相关联的数据,并且站RF数据库包括无线站信息和RF信息。 AP无线电邻接是由特定交换机拥有的AP是否可以检测另一个交换机拥有的其他AP来确定。 站和RF信息数据库仅在具有AP无线电邻接的交换机的子集内共享。

    • A router comprises a route resolution module to maintain routing information in accordance with a topology of a network, and an indirect next hop manager to maintain indirect next hop data that associates protocol next hops with forwarding next hops. The route resolution module invokes an application programming interface (API) of the indirect next hop manager for associating and disassociating protocol next hops and forwarding next hops. In response to a network event, the route resolution module can modify the indirect next hop data to reduce the time and resources necessary to perform route resolution.

    • A network system uses a management routing instance to route management information between elements involved in management of the system. The system registers each element in the management routing instance when the element comes on line. Based on the management routing instance, the system creates management forwarding tables. The system then uses the management forwarding tables to route management information between the elements. Multiple systems, for example systems connected by a network, may exchange management routing instance information to allow elements in different systems to communicate management information with each other.
