摘要
A method for performing bulk rerouting in a transport network includes pre-computing routing paths for traffic between multiple source-destination pairs for different time slots and pre-computing an order in which changes of the routing paths are carried out across different time slots, pre-provisioning the routing paths and the order to the respective forwarding network nodes, and generating free network resources according to predefined rules that take into consideration traffic preemption and exploiting the free network resources to bootstrap and/or to facilitate a rerouting sequencing of routing path switching and/or swapping in bulk rerouting across different time slots.
