  • Publication number: 20110173489
    Abstract: The present invention discloses a method for controlling failure recovery of Ethernet loop protection and an Ethernet loop node. The method comprises: when a node adjacent to a failed link detects recovery of the link, blocking a port just recovered, setting the port to be in a pre-forwarding state and starting a timer, and releasing the port temporarily blocked if the node adjacent to the failed link has not received a control protocol message sent by a master node during a timing period of the timer, and transferring the port from the pre-forwarding state to a forwarding state. The present invention allows a port of a node adjacent to a recovered link to enter into a forwarding state from the pre-forwarding state as early as possible on the premise that a corresponding control protocol message is unable to be received in time.

  • Publication number: 20110164613
    Abstract: A media negotiation method for an IP multimedia link is used in the process of establishing an IP multimedia link between a first entity and a second entity via an application server (AS) of an IP multimedia subsystem (IMS). AS sends the second entity an invite message, which includes media resource information of the first entity; When AS receives a message with media resource information from the second entity before an answer message is received or after it receives a response message with media resource information from the second entity, AS sends an IMS re-invite message without media source information to the first entity; the AS, after receiving the IMS signaling message with media resource information from the first entity, sends the first entity the media resource information returned by the second entity. The present invention is applicable to an IMS centralized service and may effectively reduce the number of steps and the time required after response for media resource re-negotiation.
