ARCHITECTURE
• Networks are used to interconnect computer sub-systems
to construct multiprocessors or multicomputer.
• These networks are used to provide internal connections
among processors, memory modules and I/O ports in a
computing sub-system.
• Various generalised topologies are used for building these
networks for efficient communication to give best parallel
computing performance.

3. 1. Functionality : Data routing, Interrupt Handling, Synchronization,
Requests, etc.
2. Network Latency : Worst-case time delay for a unit message
transfer.
3. Bandwidth : Maximum data transfer rate.
4. Hardware Complexity : Implementation Cost for wires, switches,
connectors, etc.
5. Scalability : Ability to expand with increase in resources.
Factors affecting the network
performance :
