Abstract

Switching between protocols based on environment is an elegant idea of enabling adaptation in distributed systems. Also self-stabilizing algorithms have been proposed as a mechanism to handle transient failures in distributed systems. In this work we illustrate self-stabilizing distributed protocol switching by proposing a self-stabilizing algorithm for dynamically switching between a BFS tree and a DFS tree. At low network load, the BFS tree may be used for broadcasting messages since it also minimizes delay. At higher network load, the DFS tree may be used to reduce the load on any one node. Both trees are rooted at the common broadcast source. Different properties relating to the delivery of broadcast messages under different failure conditions are investigated.
