Fast packet switch architectures for broadband integrated services digital networks

Article Abstract:

The design in networks is moving from devising efficient ways to use the bandwidth of transmission facilities to devising ways to support new high bandwidth applications and to design a single communications system to support all services. Networks are based on two principal switching techniques: circuit switching and packet switching. Packet switching divides the data into blocks of a specified maximum length and then transmits the block over the network. The challenge with ISDNs is to develop a packet switch capable of handling 100,000 to 1,000,000 packets per second per input line. Photonic switches which handle optical signals without the need to convert the optical signal to electronic signals are under development. Considerable work remains to be done on switches.

Issues in packet radio network design

Article Abstract:

There are several common issues involved in the design of packet radio networks: sharing the common radio channel; methods of determining connectivity routing data through the networks; and methods for managing and controlling the distributed network. Decisions in developing packet radio networks depend on environment, performance requirements, and cost. These design issues, decisions, and examples of existing and developing networks are discussed.
