- the best-effort services of traditional IP networks can no longer meet the needs of applications. Such as VoIP business, If the message transmission delay is too long, it will be unacceptable to the user.
- service level agreements service level agreements
- SLA service level agreement
- a special platform called a policy server (PS) is also needed. It applies for and issues QoS policies with devices at the network backbone layer and convergence layer through a special protocol—a public open policy service protocol (Cobandon Open Policy Service, COPS, RFC2748).
- COPS Cobandon Open Policy Service
- the purpose of the present invention is to provide a method of network management based on quality of service, which can organically combine network service quality management with user management and business management, and improve the quality and efficiency of network service quality.
- the method for network management based on quality of service includes the following steps:
- Step 1 The authentication and accounting server (radius server) customizes the corresponding quality of service (QoS) policy for the specific network application;
- Step 2 The user applies to the network data center (IDC) for the quality of service and permissions to be obtained, and provides service selection information.
- the I DC stores the above information and sends the information to the radius server;
- Step 3 The radius server authenticates the user and determines the QoS policy provided for the user based on the user's attributes and the type of service requested.
- the specific QoS policy is delivered to the convergence layer.
- configure the corresponding QoS policy for the convergence layer device and at the same time configure the convergence layer device with the access layer device for the QoS policy formulated for the access layer device;
- Step 4 According to the user's service, the radius server combines the access layer, convergence layer, and backbone layer equipment with a pre-built QoS policy to serve the user.
- the service quality and authority obtained by the user from step 2 in the network data center (IDC) are obtained through a portal page provided to the user by the IDC.
- the step 3 further includes the following steps:
- Step 31 The radius server selects a message based on the user service, and Service pre-made QoS policy, determine the QoS policy provided for the user, and send the policy and the corresponding device port information to the convergence layer device. At the same time, the radius server also sets the user's charging policy based on the user's personal information and the applied service. ;
- Step 32 After the convergence layer device receives the above policy and corresponding device port information, it sets a corresponding QoS processing method on the corresponding device port, and sends a QoS policy that sets the user's corresponding port and priority usage mark to the layer 2 device;
- Step 33 The convergence layer device and the access layer device respectively send back a Q0S policy configuration success message to the upper layer device, and the backbone layer device directly performs queue scheduling according to the priority flag marked for the IP packet on the convergence layer device, and then all devices are successfully configured. After that, specific services are started to be executed, and at the same time, the radius server starts to charge users according to the established charging policies.
- the step 31 further includes: if the user's service is a two-way service, sending the QoS policy provided for the user to the convergence layer device of the called party.
- Setting the corresponding QoS processing method on the corresponding device port as described in step 32 includes formulating a flow classification rule to distinguish specific user traffic, and formulating a QoS policy for the traffic.
- step 32 if the user terminal marks the priority of the QoS policy by itself, the corresponding user port is configured to trust the priority of the user traffic as a high priority.
- the present invention uses the radius server of the existing network to customize the corresponding quality of service (QoS) policy for specific network applications, when authenticating a user, the QoS policy provided for the user is determined according to the user's attributes and the type of service requested And deliver specific QoS policies to the convergence layer and access layer devices, and finally according to the user ’s business, It integrates the access layer, convergence layer, and backbone layer equipment and uses pre-made QoS policies to serve users. By adopting the above solution, it can make full use of existing network equipment, simplify the policy configuration process, and combine business management and network management.
- QoS quality of service
- FIG. 1 is a flowchart of an embodiment of a method according to the present invention
- FIG. 2 is a network structure diagram to which the method of the present invention is applied.
- the essence of the present invention is to use the existing authentication and accounting server (radius server) and broadband access server (BAS) and other equipment on the network to make information related to QoS policies through a set of interactive processes to enable network service quality management and users.
- authentication and accounting server radio server
- BAS broadband access server
- business management are combined organically, and the complicated control method of the policy server is omitted, which reduces the complexity of the network and solves the problems caused by the separation of business and control.
- FIG. 2 is a network structure diagram to which the method of the present invention is applied.
- the backbone layer is generally implemented using a Gigabit Switch Router (GSR). It requires a large-capacity, high-speed, high-efficiency, and powerful routing capability.
- the access layer generally uses low-cost devices, such as Layer 2 switches and ADSL (asymmetric user loop) access devices. It requires management management.
- the environment adaptability is strong; the convergence layer, as the boundary between the second and third layer of the metropolitan area network, should have intelligent features and user management capabilities, which is the key to achieving network management characteristics based on quality of service.
- IDC Network Data Center
- IDC Network Data Center
- FIG. 1 is a flowchart of an embodiment of a method according to the present invention.
- the invention is implemented according to FIG. 1.
- the radius server is first expanded to serve as a service management platform, and a corresponding QoS policy is customized for a specific network application.
- the user attributes and service types are distinguished.
- the formulation of specific policies should refer to the user's traffic classification method, the bandwidth requested by the user, the bandwidth upper and lower limits, delay jitter, the priority of the user service, and traffic monitoring parameters , The length of the service that can be provided, whether it is a two-way service, and the corresponding charging policy; for the charging policy, different services usually have different charging policies, and the same service has different service levels and different service hours. There can also be different charging policies.
- the broadband access server (BAS) at the convergence layer performs basic network access authentication on the user, assigns a network address to the user, and the user obtains basic access to the network; at the same time, through the standard radius protocol Record the basic information of the online user on the service management platform.
- BAS broadband access server
- any traffic of the user is processed according to the best effort principle (bas t effort).
- IDDC network data center
- the user selects the QoS service method to be obtained, such as the QoS level, and enters the corresponding user name and password to provide the service to be completed.
- the B AS device will obtain the user's personal information, service selection information, and the user's belonging The device port is forwarded to IDC.
- IDC stores the above information and sends the information to the radius server.
- the radius server authenticates the user in step 3.
- the QoS policy provided for the user is determined according to the user's attributes and the type of service requested.
- the specific QoS policy is issued to the convergence layer.
- the BAS configures the QoS policy of the corresponding service for the access layer device to the access layer device, such as configuring the priority of the relevant user access port. 3. Configure the priority of related user service flows.
- the Radius server uses the pre-built QoS policies to serve users in combination with the access layer, convergence layer, and backbone layer devices according to the user's service.
- IDC judges whether it is a legitimate user according to the user's subscription information. If yes, the user authentication information is sent to the radius server through the interface with the radius server. At the same time, the service type selected by the user and the device port to which the user belongs are also sent to the radius server. Second, IDC does not verify the validity of the user. Instead, all the information of the user is directly sent to the radius server, and the radius serever checks the contracted user information recorded to determine whether the user is legitimate.
- the radius server uses the user service selection message obtained from IDC and combines the QoS policies pre-made for this type of service on the service management platform, such as the bandwidth and delay required by VoD services. , Priority parameter Etc.) Determine the user's QoS service policy, and send the policy and corresponding device port information to the BAS device together with the radius message that the user has passed. If it is a two-way service flow (such as a conference TV), the service management platform also needs to issue a similar policy to the BAS device of the called party. At the same time, the radius server also needs to set the user's billing policy according to the user's personal information and the application for the service.
- the BAS at the aggregation layer can set the corresponding QoS processing methods on the corresponding device ports, such as: formulate flow classification rules to distinguish the traffic of specific users; formulate QoS policies (bandwidth restrictions, priority) for the traffic Changes in the level flag, how to handle default traffic, etc.).
- the BAS at the aggregation layer delivers a QoS policy that sets the user ’s corresponding port and priority to use the marked QoS policy to the second layer, that is, the access layer device. For example, if the port traffic is set to a high priority, if the user terminal marks the priority of the QoS policy itself, You can also configure the corresponding user port to trust the priority of user traffic as high priority
- the convergence layer devices that is, the BAS, and the access layer device respectively send back a Q0S policy configuration success message to the upper layer device.
- the backbone layer device does not need to do any configuration for specific users, and directly according to the convergence layer Priority marks marked for IP packets on the device are used for queue scheduling, and then after all devices are successfully configured, specific services are started, and the radius server starts to charge users according to the established charging policy.
- the radius server notifies the aggregation layer device to delete the QoS policy related to the user, and at the same time, the user's service flow is not affected. Then do QoS processing.
- the aggregation layer notifies the user-accessed Layer 2 switch port to delete the related QoS policy. If the QoS policy is deleted successfully, the devices at all levels respectively send back a Q0S policy deletion success message to the upper device.
- the service management platform performs charging operations according to the type of user, the type of service (bandwidth, priority) provided to the user, and the specific charging policy. If the BAS performs charging, the service management platform needs to notify the BAS to end the charging, in addition to sending a delete QoS policy message to the BAS.
