摘要: The present invention provides a high switching capacity network device in one telco rack including both physical layer switch/router subsystems and an upper layer switch/router subsystem. Instead of providing a single physical layer switch/router subsystem, multiple physical layer switch/router subsystems are provided. Segmenting the physical layer switch/router into multiple, for example, four, subsystems better utilizes routing resources by allowing etches for the physical layer subsystems to be moved away from the center of the mid-plane/back-plane of the network device. Moving the physical layer subsystem etches away from the center of the mid-plane enables the network device to include an upper layer/switch router subsystem with etches toward the center of the mid-plane. 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 run 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.

摘要: The present invention provides a method and apparatus for supporting multiple redundancy schemes in a single network device. In one network device, various redundancy schemes are supported including 1:1, 1+1, 1:N, no redundancy or a combination of redundancy schemes. In addition, the redundancy scheme or schemes for physical network device cards (i.e., universal port cards) or ports may be different from the redundancy scheme or schemes for forwarding network device cards. For example, a network manager may want to provide 1:1 or 1+1 redundancy for all universal port cards and/or ports but only 1:N redundancy for each N group of forwarding cards. As another example, the network manager may provide certain customers with 1:1 redundancy on both universal port cards (or ports) and forwarding cards to ensure that customer's network availability while providing other customers, with lower availability requirements, with various other redundancy scheme combinations, for example, 1:1, 1+1, 1:N or no redundancy for port cards or ports and 1:N or no redundancy for forwarding cards. The present invention allows customers having different availability/redundancy needs to be serviced by same network device.

摘要: The invention provides a method for fault isolation in a computer system, such as a network device. The method calls for providing a plurality of modular processes, and forming groups, based on hardware in the computer system, of one or more of the plurality of modular processes. A fault within a group is detected, and recovery from the detected fault is accomplished without affecting processes or hardware in other groups.
