Method and apparatus of routing convergence in control plane of an intelligent optical network |
摘要 |
<p>The embodiments of the present invention provide a method of routing convergence in a control plane of an intelligent optical network, which includes: a function unit perceiving a service link state transmitting an alarm notification message indicating a failure in a service link to a routing protocol unit when the service link is in failure; the routing protocol unit confirming a service link failure in the control plane according to the alarm notification message. The embodiments of the present invention also provide an apparatus of routing convergence in a control plane of an intelligent optical network. According to the embodiments of the present invention, the establishment of a new service or re-routing may be implemented within several seconds or even hundreds of milliseconds after the service link failure in the control plane occurs.</p> |
