Abstract
A technique increases the efficiency of functions performed by an intermediate device of a computer network by encoding a portion of a routing information field (RIF) of a token ring frame transported over the network with information for use by the device. The maximum number of route descriptor (RD) hops in the network is altered to provide a predetermined portion of the RIF for storing encoded information. Each intermediate device configured in accordance with the technique identifies this predetermined portion as that portion of the RIF immediately following its matching RD.
