Method for dynamically providing end-to-end connections in an asynchronous transfer mode (ATM) network
Abstract
A method for routing data cells in a computer network having a number of nodes and network resources, each node and network resource having a memory, the memories of the network resources each having routing software, storing a number of node connections in each of the memories of each of the nodes, storing a plurality of network resource connections in each of the memories of each of the network resources, selecting a first node, the first node having data cells to transmit, selecting in the first node a first node connection, transmitting the cells on the first node connection to a first network resource, receiving the cells in the first network resource, selecting in the first network resource a first network resource connection, and transmitting the cells on the first network resource connection.

Dobbins, et. al. Sept. 14, 1999

Network interconnecting apparatus having a separate forwarding engine object at each interface
Abstract
An interconnecting apparatus includes one or more interfaces. Each interface connects to a network. The interconnecting apparatus interconnects the networks attached to the interfaces. The device utilizes distributed autonomous forwarding engines on each interface in that each interface has a forwarding engine corresponding to it. Each forwarding engine only knows the configuration information and how to receive and transmit packets on the one interface to which it corresponds. Each forwarding engine acts independently to process packets, yet each interacts together to collectively provide packet forwarding which is protocol independent, interface independent, and scalable.
