Abstract

Computer communication networks employing a subset of fixed routing schemes known as "explicit Path Routing" [1,2,3] need mechanisms to keep track of the status of these routes, i.e., whether they are inoperative, operative, or active. The most frequent reasons for status changes are temporary link and node failures, and operative path activations. For networks of moderate size the status notification employed presently [2,3] seems to be adequate. For large networks consisting of many nodes the status notification traffic thus generated represents a significant additional load for transmission links and processors which can lead to substantial performance degradations or require additional resources.
