Description

Description: A service scheduling method and network convergence device thereof

[1] The present invention relates to the field of data communication technologies, and in particular, to a service scheduling method and a network convergence device thereof.

[2] The prior art provides a service scheduling method in a dual-edge or multi-edge network architecture in an Ethernet environment, as shown in FIG. 1 , which is a flowchart of an existing service scheduling method. The core content of the method is as follows:

[3] S01, listening for multicast messages of services managed on the network convergence device;

[4] S02: Perform parameter adjustment on the service according to the multicast message that is heard;

[5] S03. Perform traffic control on the service according to the adjusted parameters.

[6] In the process of implementing the prior art, the inventors found the following problems:

[7] The aggregation device can only schedule the services managed by the aggregation device. When the services carried by the aggregation device are offloaded to other network devices, the aggregation device cannot uniformly schedule the service.

[8] As shown in Figure 2, in the triple play (Triple Play) typical networking, high-speed Internet access service (High

Speed Internet Access Service (HSI) is provided by Broadband Access Server (BRAS), and Triple Play service is provided by Service Router (Service).

Router, SR) is provided. Generally, the service router transmits the traffic of the HSI service to the BRAS through Layer 2 switching or transparent transmission according to the VLAN/QinQ information. Therefore, the SR cannot uniformly schedule the services of the same home or the same user. For example, a home has three services: voice (VoIP), video (Video), and HSI. The VoIP service and the video service are terminated on the SR and processed by the SR, and the HSI service is transparently transmitted from the SR to the BRAS. Since the SR only transparently transmits traffic to the HSI service and does not perform any processing, the services of the same family are distributed on different devices (such as SR and BRAS). The SR has no way to uniformly schedule the three services.幵 Technical solution

[9] The embodiment of the invention provides a service scheduling method and a network convergence device thereof. Unified service scheduling can be performed on all services carried in the network aggregation device.

[10] In order to achieve the above effects, the embodiment of the present invention provides a service scheduling method, where the method includes: [11] acquiring user service information of service data;

[12] Perform unified traffic control on the service data according to the user service information.

[13] Correspondingly, an embodiment of the present invention further provides a network convergence device, where the device includes:

[14] a service identification unit, which is used to obtain user service information of service data;

[15] The service processing unit is configured to perform unified traffic control on the service data according to the user service information.

Embodiments of the invention

Referring to FIG. 3, the figure is a specific implementation process of an embodiment of a multi-level service scheduling method provided by the present invention. Specifically, the process of implementing a service scheduling is as follows:

[22] 11: Obtain user service information of the service data carried in the aggregation device, where the service data includes service data that is terminated by the aggregation device and the aggregation device.

[23] 12. Perform unified traffic control on the service data according to the user service information.

[24] Specifically, the user service information mainly includes user line information and a service category.

[25] Referring to FIG. 4, the specific implementation, 11 may specifically include:

[26] 111. Obtain a service identifier that ends the service data transparently transmitted by the aggregation device and the aggregation device;

[27] 112. Identify user line information and service category of the service data according to the service identifier.

[28] Referring also to Figures 3 and 12, the following may specifically include:

[29] 121, determining, according to the user line information and the service category, service data belonging to the same subscriber line Business priority. The correspondence between the service type and the service priority is shown in Table 1: Table 2 Table of correspondence between service type and service priority

[31]

[32] Among them, the priority is arranged in descending order, that is, priority 1>priority 2>priority 3.

[33] 122. Allocate corresponding bandwidth to the service data in the aggregation device according to the service priority.

[34] Specifically, the network convergence device generally refers to a broadband network gateway or a service router.

Router, SR), the service categories carried in the aggregation device include audio, video, and data access services.

[35] The service identifier can be the following two types:

[36] 1, VLAN / QinQ tag

[37] Generally, the traffic of different service terminals of the same user is marked with the same virtual local area network (Customer Premises Equipment (CPE) (such as RG).

The Net _WO rk, VLAN) tag, as shown in Table 2, the audio, video, and data access services of User 1 are labeled V LAN1001, and the audio, video, and data access services of User 2 are labeled VLAN 1002. Digital Subscriber Line Access Multiplexer (Digital Subscriber Line Access)

Multiplexer, DSLAM) or Ethernet Collection (Ethernet

At the Aggregation point, different outer VLANs are marked for different services. As shown in Table 3, the audio, video, and data access services of User 1 and User 2 are added with VLANs 101, 102, and 103, respectively, so that User 1 arrives at SR. The packets of the three services are (101, 1001), (102, 1001), (103, 1001), and the packets of user 2 arriving at the SR service are (101, 1002), (102, 1002), (103). , 1002).

[42] Among them, the outer VLANs are 101 and 102 audio and video services in Service

The data access service with the outer VLAN of 103 is transparently transmitted to the broadband access server (BRAS) through the SR and terminated by the BRAS.

[43] 2. DHCP Option82/PPPOE Circuit ID

[44] Another alternative is through Dynamic Host Configuration (Dynamic Host Configuration)

Protocol, DHCP) Option 82/Point to Point Protocol over Ethernet (PPPOE) Circuit

ID to identify the traffic of the same user. The principle is in DSLAM or Ethernet

The Aggregation point hits the corresponding corresponding identifier in the user-initiated signaling packet, and the SR identifies whether it belongs to the same user according to the identifier.

[45] For example, on the switch as a DHCP Relay (or with DHCP)

Snooping can also do the same thing) 吋 DHCP

The Request message is rewritten, plus the user's line information, and then reported to the SR or BRAS. PPPOE Circuit

The ID is the line identification information in the PPPOE application environment. For example, if different terminals of user 1 initiate a DHCP request, the switch acts as DHCP.

Relay, add the same DHCP to the DHCP signaling packets of the three terminals according to the subscriber line. If the mapping between the user source MAC address (and/or the subsequent IP address) and the Opti ₀ n82 is recorded, the terminal with the same Option 82 information belongs to the same user. Similarly, SR can be similarly processed when transparently transmitting PPPOE traffic.

[46] Based on the above two line identification methods, the SR associates the corresponding services of all terminals belonging to the same user, regardless of whether the service of the terminal is terminated or transparently transmitted, and unified service-based scheduling is performed, thereby ensuring the user. Ensure that multiple applications are running simultaneously while the line bandwidth is constant.

[47] For example, User 1 currently has audio, video, and data access services with a line bandwidth of 10 Mbps, audio services requiring 128 Kbps of bandwidth, video services requiring 4 Mbps, and data access services using line bandwidth, due to service priority: Audio > Video > Data access. When there is no audio or video service, the data access can use the line 10Mbps.

Bandwidth, when there is audio and video traffic, data access uses the remaining 6Mbps bandwidth of the line.

[48] When the network is congested, DiffServ scheduling is performed on the packets according to the service priority. The data access service can be discarded preferentially to ensure video services. In the solution provided by the embodiment of the present invention, the service is scheduled based on the user line information and the service class priority on the SR. To ensure the audio and video services, the user 1 performs scheduling and discards the data access service. It affects the data access services of other users.
