The performance of interconnection networks is measured on the below parameters.
1) Bandwidth: It determines maximum transfer rate between any two nodes. It is measured in MB per second or GB per second.
2) Functionality: It refers how interconnections network maintains synchronization, interrupt handling, request/message combines, coherence and data routing.
3) Latency: In interconnection networks different nodes can be at different distances depending on the topology. The network latency indicates to the worst-case time delay for unit message when transferred via the network between farthest nodes.
4) Scalability: It indicates to ability of interconnection-networks for modular expansion with a scalable performance with rising machine resources.
5) Hardware Complexity: It denotes to the cost of hardware logic such as switches, wires, connectors, arbiter which are needed for implementation of interconnection network.
