Embodiment Construction

[0022] The solution recorded in the embodiment of the present invention is to pre-judgment when the path is calculated before the new service is opened, and judge whether the Bypass operation of the path will be triggered after the new service is opened according to the transmission path of the original service, and if so, first Do not perform service provisioning, but instead calculate the Bypass path. After the bypass path is successfully established, directly carry the new service on the Bypass path; otherwise, activate the new service according to the original service transmission path.

[0023] in the same figure 1 In the network environment shown, combined with the attached figure 2 The present embodiment is described in detail:

[0024] Step 201: Receive a new service establishment request;

[0025] Specifically, after receiving the establishment request of the new service SP4, request to establish the LSP4 service path; the new service establishment request carries ...

Abstract

The embodiment of the invention discloses a bypass processing method, which comprises the following steps: receiving a new service establishment request message, and acquiring bandwidth resource information required by new service; according to the bandwidth resource information required by the new service, judging whether Bypass operation of a transmission path can be triggered if the new service is loaded according to the prior service transmission path; if so, loading the new service according to a Bypass path after establishing the Bypass path; and otherwise, loading the new service according to the prior service transmission path. The embodiment of the invention also discloses a bypass processing device, a bypass processing system and a router. The bypass processing method, the bypass processing device, the bypass processing system and the router reduce interruption times of the service in the process of opening the new service, and improve service experience.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a bypass processing method, device, system and router. Background technique [0002] In the general MLN (Multi-Layer Network) model, the upper and lower networks are client / service models, and the lower network establishes FA tunnels to construct the node topology connection relationship of the upper network. Generally, the higher the upper layer, the smaller the granularity of service exchange, and the lower the exchange, the larger the granularity of service exchange. Due to the complexity of circuit design, for the same capacity of business switching, the smaller the granularity of the switching, the more complex the technology, the higher the process requirements, and the more expensive the cost. Therefore, in network deployment and traffic control, a basic principle is to try to forward the business to the lower-layer nodes, so that the total network processing cost will b...
