<p>In an embodiment, a method is disclosed for minimizing soft preemptions of LSPs. Upon receiving a reservation message for an LSP whose requested bandwidth that exceeds the available bandwidth of downstream links, a network node may select a set of LSPs for soft preemption and share the selection with other nodes along their paths, both upstream and downstream. By coordinating the selection of LSPs to soft-preempt among nodes on the path, fewer LSPs may require soft preemption, which may result in minimizing excessive network disruptions, and thus, allowing the network to function more efficiently.</p> |
