摘要:
Diversity constraints with respect to connections or links in a client layer are conveyed to a server layer where those links or connections are served by paths in the server layer. A network device in the server layer stores data associated paths in the server layer with identifiers for connections in the client layer. The network device in the server layer receives from a network device in the client layer a request to set up a path in the server layer for a connection in the client layer. The network device in the server layer receives information describing the diversity requirements associated with connections in the client layer. The server layer network device computes a route in the server layer for the connection specified in the request based on the diversity requirements.

摘要:
A network device routes data packets by storing the packets in a switching memory as a function of a destination address of the packet. The switching memory comprises switching memory queues that are mapped to ports of the device. A header of a received packet is examined to determine the network destination address to which it is to be routed, and a destination queue is assigned to the packet based on the destination address. Thereafter, the packet is divided into cells, and the cells are written to contiguous locations in the destination queue.
摘要:
A method and system for providing enhanced services for a network. The enhanced services use information about the network which is available to a subnet of communicating processors (such as a set of routers), collectively executing a common distributed technique for disseminating that network information. The router subnet collects network topology information and provides a service using that network topology information, responsive to requests from non-routers coupled to the network (such as a set of host processors). The router subnet also collects information advertised by hosts coupled to the network, and disseminates that host information to substantially all routers, using the common distributed technique for disseminating network topology information. The host information may comprise information about server processes available at the originating host (such as what services are available and to which users those services are available), or may comprise information about client processes operating at the originating host (such as which users are operating those client processes and which services they desire).
摘要:
A method for tracking a transmission status of one or more data elements to one or more devices. In one example, the method includes providing a list including one or more devices and one or more data elements; processing the list to determine a data element of the one or more data elements to transmit to a device of one of the one or more devices; and upon successfully transmitting the data element to the device, adjusting the list so that the list indicates that the device has received the transmitted data element. In this manner, the status of whether a particular data element has been sent to a particular device can be easily derived from the list.
