摘要： The present invention provides a method and apparatus for improving transmission of control information within a network device and between multiple connected network devices. Specifically, a control path is included within a network device that is independent of the data path and dedicates control path resources to each distributed processor within the network device. Dedicating resources insures that each processor has sufficient bandwidth on the control plane to transmit control information at high frequencies. This may prevent starvation of data transmissions during periods of high control information transfers and may also reduce the likelihood or further spreading of control information storms when one or more network devices in a network experiences a failure.

摘要： The present invention provides a network device, such as a network switch or a router, having a high degree of modularity and reliability. The network device includes a data plane and a control plane. The data plane relays datagrams between a pair of receive and transmit network interface ports. The control plane runs management and control operations, such as routing and policing algorithms which provide the data plane with instructions on how to relay cell/packets/frames. Further, the control plane includes an internal control device that is primarily responsible for managing the internal resources of the network device, and a separate external control device that is primarily responsible for operations relating to the interfacing of the network device with an external environment.

摘要： The present invention reduces the cost of a minimally configured network device by providing a network device with a distributed switch fabric. Such a network device locates a portion of the switch fabric functionality on each forwarding card allowing the minimal network device configuration to include less than the entire switch fabric functionality. The cost of the minimal configuration is, therefore, reduced allowing network service providers to more quickly recover the initial cost of the network device. As new services are requested, additional functionality, including both forwarding cards and universal port cards may be added to the network device to handle the new requests, and the fees for the new services may be applied to the cost of the additional functionality. Consequently, the cost of the network device more closely tracks the service fees received by network providers.
摘要翻译：本发明通过向网络设备提供分布式交换结构来降低最低配置的网络设备的成本。这样的网络设备在每个转发卡上定位交换结构功能的一部分，允许最小的网络设备配置包括少于整个交换结构功能。因此，最小配置的成本降低，允许网络服务提供商更快地恢复网络设备的初始成本。当请求新服务时，可以向网络设备添加包括转发卡和通用端口卡的附加功能来处理新的请求，并且新服务的费用可以应用于附加功能的成本。因此，网络设备的成本更加紧密地跟踪网络提供商接收的服务费用。

摘要： The present invention provides a network device that fully utilizes the available space in a standard telco rack through the use of multiple mid-planes. Full utilization of available space allows a high switching capacity network device including both physical layer switch/router subsystems and upper layer switch/router subsystems to be fit in one telco rack. Inter-mid-plane connections may be provided by connecting switch fabric cards and/or control processor cards to each of the mid-planes. Providing a multi-layer network device in one telco rack allows for intelligent layer 1 switching (for example, dynamic network connection set up), allows for one network management system to control both layer 1 and upper layer networks and eliminates grooming fees. Compared with separate layer 1 and upper layer network devices or a multi-layer network device occupying multiple telco racks, a single network device saves valuable telco site space and reduces expenses by sharing overhead such as the chassis, power and cooling.
