Abstract: The embodiments of the 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 invention also provide an apparatus of routing convergence in a control plane of an intelligent optical network. According to the embodiments of the 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.

Abstract: A method and apparatus for adjusting timeslot fragments of multiple links in an Automatically Switched Optical Network (ASON). The method includes the steps of: obtaining link information of multiple links necessary for timeslot fragment adjustment, calculating adjusted link information of each link according to the link information, and adjusting a timeslot allocation of each link according to the adjusted link information.

Abstract: The present invention relates to a method and an apparatus for consistency verification of traffic engineering link timeslot status, including: the transmitting end transmits a timeslot status verification request message containing the timeslot status object class of a local end of a corresponding traffic engineering link to the receiving end; the receiving end compares and verifies the timeslot status object class of the transmitting end of the corresponding traffic engineering link with the timeslot status object class of the local end after the receiving end receives the message, and notifies a local end link resource manager of the result of verification and the timeslot status object class of the opposite end. With the method according to the embodiments of the present invention, the consistency of traffic engineering link timeslot statuses can be periodically detected, the inconsistency of traffic engineering link timeslot statuses can be discovered as early as possible.
