Optical IP Switching - Wikipedia
Optical IP Switching (OIS), is a novel method of creating transparent optical connections between network nodes using a flow-based approach. An IP flow is a collection of IP packets going from the same source to the same destination: the exchange of IP packets is the mechanism that allows the transport of information over the Internet. Recent studies have shown that Internet traffic presents a heavy tail distribution, where a small number of flows carries a huge amount of data. This suggests the possibility of dynamically adapting the optical connections to carry these heavy flows. Currently a packet has to traverse a certain number of routers, before reaching its destination and the network routers must analyze each packet and forward it towards the direction of the destination node. However, since a flow is defined as a sequence of packets going from the same source to the same destination, if the router recognises the flow it could create a short-cut by creating a “switched” connect
