Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] In this embodiment, a method for establishing a cross-domain connection is provided. image 3 is a flowchart of a method for establishing a cross-domain connection according to an embodiment of the present invention, such as image 3 As shown, the process includes the following steps:

[0034] Step S302, storing the actual path queried from the path computation unit PCE of the domain to which the node belongs to the node locally;

[0035] Step S304, establishing a cross-domain connection according to the actual path stored locally by the node.

[0036] Through the above steps, the actual path stored on the PCE is stored locally on the node, which not only solves the problem in the related a...

Abstract

The present invention discloses a cross-domain connection establishment method and device. The method comprises a step of storing an actual path inquired from a path calculation unit PCE of a node belonging domain to a node local, and a step of establishing a cross-domain connection according to the actual path stored in the node local. The problem of the burden of the PCE caused by a condition that the PCE needs to store a large amount of path information in the related technology is solved, thus the actual path is stored in the node local, the cross-domain connection is carried out according to the actual path stored by the node local, and the burden of the PCE is reduced greatly.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for establishing a cross-domain connection. Background technique [0002] With the continuous development of Automatically Switched Optical Network (ASON) technology, more and more service providers begin to use optical network equipment to build networks, and network services based on a single autonomous domain (hereinafter referred to as domain) have become Can not meet the needs of practical applications. Since the ASON control plane technology basically complies with a unified standard, for example, the link management module (Link Management Protocol, referred to as LMP) protocol, the signaling module (Resource Reservation Protocol, referred to as RSVP) protocol, the path calculation module (Path ComputationElement Communication Protocol, referred to as PCEP) agreement, etc., make it possible to realize the collaborative work between different domains. ...
