Embodiment Construction

[0039] refer to figure 1 , which illustrates a block diagram of system functionality and may include the following modules:

[0040] 1. The task receiving module receives the service parameters issued by the network management, specifically the source and destination IP or MAC addresses.

[0041] 2. The task analysis module receives the parameters sent from the task receiving module, and connects to the first-level database to analyze and process the business parameters through the function processing module.

[0042] 3. The task sending module receives the parameters of the task analysis module, and sends different types of parameters to the secondary control units of different hierarchical domains through the restful interface according to the business type.

[0043] 4. The link protection module is connected to the first-level database to obtain the link status in real time. When the switch or the link is disconnected, the task analysis and task delivery module is started ...

Abstract

The invention discloses a method for communicating a third-level domain and a second-level domain in a software-defined packet transport network (SPTN) and a system. The method comprises the following steps that a database collects external information; a primary control unit receives services, and performs path calculation according to a source address and a destination address of the services; and a secondary control unit issues a task after analyzing service parameters transmitted by the primary control unit. The system comprises the primary control unit and the secondary control unit, wherein the primary control unit comprises a task receiving module, a task analyzing module, a task issuing module, a link protection module, an alarm module, a primary database and a task uploading module; and the secondary control unit comprises a secondary task issuing module, a secondary database, a second-layer anti-looping module, an ARP module and a switch module. Through adoption of the method and the system, communications between the third-level domain and the second-level domain of an SPTN domain can be realized, namely, service flows can be transmitted from an Internet protocol (IP) layer to a media access control (MAC) layer and can be transmitted from the MAC layer to the IP layer. Moreover, link protection, alarm and quality of service (QoS) setting functions are provided, so that the reliability and robustness of the network are ensured.

Description

technical field [0001] The present invention relates to a software-defined packet transport network in the communication field, that is, an SPTN network, and is a method and system for intercommunication between a layer-3 domain and a layer-2 domain in a software-defined packet transport network. Background technique [0002] Since the data link layer is the second layer in the five-layer protocol of the computer network, corresponding to the two-layer header of the data packet, and the network layer is the third layer, corresponding to the three-layer header of the data packet, so in this patent , the area formed by devices matching MAC addresses is referred to as a Layer 2 domain, and the area formed by devices matching IP addresses is referred to as a Layer 3 domain. [0003] Software-Defined Packet Transport Network, or SPTN for short, has been widely used in Layer 2 domains. However, SPTN is not widely used in Layer 3 domains. As the idea of ​​software-defined networks...
