example 1

[0187] SPTN includes: APP layer, control layer and forwarding layer.

[0188] APP is application software;

[0189] The control layer is layered, including: SC control layer and DC control layer. SC is the super controller, and DC is the domain controller. The SC needs to understand the actual physical topology controlled by the DC, and needs to divide each layer of topology into different domains, and each domain is controlled by a different DC.

[0190] The forwarding layer includes: NE. Such as Figure 9 As shown, NE1, NE2, NE3 and NE8, NE9, NE10 belong to the miniaturized PTN. NE4, NE5, NE6, and NE7 belong to the MAN SPTN. The miniaturized PTN and the metropolitan SPTN here belong to different domains. exist Figure 9 It also shows an element management system (Element Management System, EMS) for network management.

[0191]If two tunnels need to be established, one tunnel enables transparent transmission of service data from NE1 to NE9; the other tunnel enables tr...

[0201] Similarly, if the current SC needs to create a service tunnel corresponding to the UNI or NNI interworking mode, the following steps can be taken:

[0202] 1. Divide the physical DC of a domain into multiple logical DCs, and configure one IP address for each logical DC. For example, logical DC1 is configured with IP1 and logical DC2 is configured with IP2.

[0203] 2. The SC issues routing calculation requests, and sends routing requests to the involved DCs and physical DCs in other domains respectively. In this case, the physical DC of the miniaturized PTN will receive two routing requests, and the physical DC of the MAN will only receive routing requests. After receiving a routing request, the DC returns the routing calculation result.

[0204] 3. The SC establishes and sends the tunnel creation message. The physical DC of the same miniaturized PTN will receive the tunnel creation message twice, and will perform the tunnel creation message twice. The physical DC of t...

Abstract

The embodiment of the invention discloses a cross-domain service intercommunication method, network equipment and a storage medium. The cross-domain service intercommunication method applied to the super controller SC can comprise the following steps: when detecting that two ends of a service source sink are located in the same domain and no intra-domain communication link exists, creating a cross-domain logic link; And creating a service tunnel communicated with the two ends of the service source sink on the basis of the logic link.

Description

technical field [0001] The invention relates to synchronization technology in the field of communication technology, and in particular to a cross-domain service intercommunication method, network equipment and storage media. Background technique [0002] In the prior art, if two forwarding devices belonging to the same domain serve as the source and sink of data, the super controller (Super Controller, SC) will be regarded as a transmission service in the same domain, that is, a single-domain service. Generally, single-domain services are transmitted between two devices in the domain. In the prior art, the SC only issues the tunnel once to the domain controller (Domain Controller, DC) and supports only one tunnel establishment. This will result in the inability to communicate between two devices located in the same domain but not connected to the link; thus leading to the problem of poor interoperability of the network. Contents of the invention [0003] In view of this,...
