Up to this point, our loss networks have all had the following salient characteristic: An arriving call is admitted into the network if and only if there is sufficient bandwidth in each of the links along its predefined route. The models have conspicuously lacked alternative routes on which a call can be established when the predefined route is unavailable. Due to this absence of alternative routes, these loss networks are said to have fixed routing. Being simple to implement, fixed routing is employed in many regional and private circuit-switched networks. Moreover, it will be employed in many initial implementations of ATM.
