One of the solutions, as an example, is
to attach a subscriber identification code (not
open to the public) to a packet at source
nodes, to transport the code over several
different operators network, to detach the
subscriber identification code at destination
node, and to keep the origin-record during
predetermined period at the destination node.

Delay Variation for Realtime Packets
An advantage of the Short Length packet
Switching/Routing is to minimize the delay at a
node.
Better QoS for realtime service
