Embodiment 1

[0032] Such as figure 2 As shown, the present invention provides a structural block diagram of a preferred connection establishment device, which includes: a receiving unit 202, configured to receive a call establishment request; an acquisition unit 204, configured to obtain the head node on the link in response to the call establishment request The constraint information of the first node and the constraint information of the tail node on the link; the processing unit 206 is used to judge whether the constraint information of the first node and the constraint information of the tail node meet a predetermined condition, and if so, establish a connection.

[0033] In the preferred embodiment above, the system judges whether the conditions for establishing a connection are met by obtaining the constraint information of the first node and the constraint information of the tail node on the link before establishing the connection, and establishes the corresponding connection only w...

Embodiment 2

[0051] based on figure 2 The shown connection establishment device, the present invention also provides a preferred connection establishment method, such as image 3 As shown, it includes the following steps:

[0052] S302: Receive a call establishment request;

[0053] S304: Obtain constraint information of the head node on the link and constraint information of the tail node on the link in response to the call setup request;

[0054] S306: Determine whether the constraint information of the first node and the constraint information of the tail node meet a predetermined condition, and if so, establish a connection.

[0055] In the preferred embodiment above, the system judges whether the conditions for establishing a connection are met by obtaining the constraint information of the first node and the constraint information of the tail node on the link before establishing the connection, and establishes the corresponding connection only when the conditions are met . In th...

Embodiment 3

[0072] The present invention also provides another preferred connection establishment device, such as Figure 4 As shown, the device includes: a connection controller 402 , a call manager 404 and a local transport resource adapter 406 . Wherein, the call manager 404 includes: a connection judging unit 4041 , a network call allowing unit 4042 , a user call processing unit 4043 , a local restriction query unit 4044 , and a network call processing unit 4045 .

[0073] based on Figure 4 , the present invention also provides another preferred connection establishment method, such as Figure 5 shown. However, it should be noted that this preferred embodiment is only for better describing the present invention, and does not constitute an improper limitation of the present invention.

[0074] This preferred embodiment describes the process of completing service establishment under the condition that both the head and tail nodes use optical forwarding single boards to access client...

Abstract

The invention discloses a method and device for establishing a connection, wherein the method includes: receiving a call establishment request; obtaining constraint information of the first node on the link and constraint information of the tail node on the link in response to the call establishment request; judging the constraint information of the first node Whether the constraint information and the constraint information of the tail node meet a predetermined condition, and if so, establish a connection. The invention solves the problem of connection establishment failure caused by constraint information not satisfying the conditions in the prior art, ensures the normal establishment of the connection for business, and improves the control ability of ASON on the transmission plane.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for establishing a connection. Background technique [0002] With the increasing demand for bandwidth and scheduling capabilities of network services, the optical network is gradually evolving to the third-generation digital transport network based on the Optical Transport Network (OTN). The DWDM system provides ultra-large-capacity bandwidth, and provides flexible scheduling capabilities, networking capabilities, and protection capabilities through optical data unit (ODUk) switching at the electrical layer. At the same time, by introducing the concept of Automatically Switched Optical Network (ASON for short), three planes of management, control and transmission are formed, making the optical network more intelligent. [0003] For the establishment of ASON services in OTN equipment, from the perspective of the transmission plane, it is from the client-side...
