TLDR
In this paper, a packet switching communication network (10) includes a number of switching nodes (16) and at least one data processor (20), each of which is configured to perform a network processing function, such as packet broadcasting (74) or error correction (60).
Abstract
A packet switching communication network (10) includes a number of switching nodes (16). The switching nodes include a switch (18) and at least one data processor (20). When selected packets (34), as identified by routing codes (40), arrive at one of the switching nodes (16), they are passed (58) to the data processor (20). The data processor (20) is configured to perform a network processing function, such as packet broadcasting (74) or error correction (60). In performing these functions, user data (38) conveyed by the selected packets (34) are processed to generate processed packets. The processed packets are re-introduced to the switch (18) and routed onto their destinations.

System for communicating labeled routing trees to establish preferred paths and source routes with local identifiers in wireless computer networks

TL;DR: In this paper, a routing tree (LRTS) is produced at a router of a computer network according to a shortest path determination made over a partial topology graph of the network, which graph is produced according to knowledge of adjacent links of the router and one or more LRTs of neighboring routers.

Network apparatus for switching based on content of application data

TL;DR: In this paper, a content-based message director (e.g., XML director) is used to route or direct messages received from the network to one of the processing nodes based upon application data, including business transaction information.

Generating and navigating streaming dynamic pricing information

TL;DR: In this paper, an interactive linkage between a search engine and dynamic pricing content available on a computer network can be provided by organizing links to dynamic pricing information (e.g., bid/ask pricing information) on the computer network into a predetermined taxonomy, and providing to the search engine a mapping between search requests and the taxonomy.

Patent

System for routing and switching in computer networks

TL;DR: In this paper, a protocol for a computer network in which routing operation codes (ROCs) in headers of packets transmitted within the network specify to a receiving router which of a number of routing or switching methods to apply to forward associated packets.

Non-blocking packet switching network with dynamic routing codes having incoming packets diverted and temporarily stored in processor inputs when network ouput is not available

Tony Walker
TL;DR: In this article, a plurality of packet switches distributed throughout the network for transmitting data between a data source and destination is identified and a path created through the network to said destination based on the destination.

System and method for providing multiple loss and service priorities

TL;DR: In this article, a system and method for implementing quality of service features in a packet switch calculates QoS parameters, and inserts these parameters into the packet header before the packet reaches the switch fabric itself.

Method and system for routing information between nodes in a communication network

TL;DR: In this paper, a routing code list (RL) is proposed for routing packets from a first end node to a second end node in a communication network comprising a plurality of nodes having input/output ports, through which the packets are routed.
