Abstract
In one embodiment, a scheme is disclosed for managing network traffic load upon outage of a network node disposed in a wireless packet data network, wherein the network node is adapted to serve a substantially large number of mobile nodes using respective data connections. Upon encountering an outage-causing condition, the network node releases the data connections and generates session termination messages for transmission to the mobile nodes. Responsive to receiving the session termination messages, the mobile nodes variably delay their data session reconnect requests based on randomization.
