What Does Source Routing Mean?
Source routing is a specific routing process where senders can specify the route that data packets take through a network. This allows for troubleshooting and various transmission goals. Source routing is an alternative to traditional routing where packets just move through a network based on their destination.
Techopedia Explains Source Routing
There are two different types of source routing – loose and strict. In loose source routing, the packet has to pass through specific listed hops, but in strict source routing, the sender specifies every step on a hop-by-hop basis.
