Description

 Network route management method

Technical field

 The invention relates to a network route management method in the field of data communication. Background technique

 Today, as the Internet develops more and more, data communication has become the core of the entire Internet architecture. Data communication is the routing of data traffic, so routing can be said to be the core of data communication. Routes are typically carried by routing switching equipment, including routers and switches.

 The routes used now are generally implemented by static routes or dynamic routing protocols configured by the network planner. Static routing, as its name implies, is a statically configured route. The advantage is that it is simple to configure and easy to implement. However, the shortcomings are obvious. The configuration is large and cannot be dynamically adjusted. Once the network planning changes, all the routing switching devices involved, including routers and switches, Manual modification of configuration activities is very time consuming, laborious, and error prone. Therefore, in order to adapt to the rapid development of the modern Internet, dynamic routing protocols are generally used to generate and propagate routes. The advantage is flexibility and small configuration. Once the network changes, only a few configuration changes are required, and the dynamic routing protocol can automatically Route changes spread out, convenient and efficient.

With the increasing demand of network applications, network segmentation management has become a major trend. How to make the network design flexible and easy to control according to the needs of users has become the focus and difficulty of current network planning, and also for existing routing switching devices. Technology presents new challenges. FIG. 1 shows a typical campus network planning management diagram. A portion of the campus network is planned into four zones, and is connected to the campus backbone network through the same router 10. In control needs, network planning hopes to achieve time-sharing management. For example, in the 0 to 6 o'clock time every day, the network 21 of the A area can access the Internet, and the network of the B area 22 can access the Internet from 6 to 12 o'clock, and the C area of the 12 o'clock to the 18 o'clock. The network 23 can access the Internet; the D zone network 24 can access the Internet from 18 o'clock to 24 o'clock. The requirement that the network of each zone can access the Internet is realized by the router 10 notifying the network segment where the zone is located to the campus backbone network. However, the existing routing control technology does not automatically implement this function. Instead, the administrator needs to manually adjust the interface validity of the router 10 and the four areas manually, or manually adjust the router 10 when the management personnel handovers every time period. The policy is to route the change advertisement to the network segment where the Internet access area is located. Either way, you need someone For the manual adjustment, the workload is extremely complicated and error-prone, and the user needs are not well realized. In the above, in order to achieve accurate subdivision management, routing can work according to certain established policy rules. Only using existing dynamic routing technology is not enough to fully meet the requirements. It is necessary to provide an automatic route management method to solve This technical flaw.

 2 is a schematic view showing the steps of an embodiment of the method of the present invention.

Preferred embodiment of the invention The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and embodiments, in which the present invention can be applied to the technical problems, and the implementation of the technical effects can be fully understood and implemented.

 The main idea of the present invention is: The user plans and formulates a control policy according to network requirements, and applies to applications such as dynamic routing protocols. The routes on the routing switching device are dynamically adjusted according to the control policy, without manual intervention and complicated configuration, thereby reducing network management and The workload and complexity of the configuration.

 FIG. 2 is a schematic flow chart of an embodiment of a method according to the present invention, including the steps of:

 Step 210: The user performs network planning according to requirements, and formulates a control policy according to the plan, and configures the established control policy to the routing switching device.

 The user first clarifies the network planning needs, and then performs the network planning and formulates the control strategy. According to the campus network planning management shown in Figure 1, the above control policy is the time policy formulated by the user, and the user can clarify the routes to be advertised on each network segment, and Configured on the routing switch device, that is, in the order of B, C, and D, every 6 hours from 0 o'clock, the route is automatically transferred to the next zone to achieve the purpose of user segmentation management.

 To configure the control policy on the routing switch device, you can use the route map (Route-Map). The route map contains a number of policy configurations. The user configures multiple entries of the route map to correspond to the control policy. For example, the application instance of the time policy can be configured to make different entries take effect at different times. Settings.

 Step 220: The routing switching device dynamically adjusts the route in real time according to the configured control policy. The routing switching device configures the control policy to be applied to the dynamic routing protocol, and the routing is dynamically adjusted according to the control policy according to the application.

 The configuration of the control policy to the dynamic routing protocol described herein is a common technical means by those skilled in the art. Generally, a control name such as a route map (Route-Map) is introduced into the protocol, and the configuration command can be According to the operation of each manufacturer, the logical form is basically the same.

If you continue to use the dynamic routing protocol to advertise the zoning route, you can configure the time policy to the dynamic routing protocol, for example, using BGP (Border Gateway Protocol). You can configure the BGP peer-to-peer routing policy as the time policy. If the time policy changes periodically, you can affect BGP. The neighboring route is advertised to the neighbors, and the automatic execution of the time policy is completed. In the above example, the router 10 automatically reports the route of the network segment where the Internet accessable area is located to the backbone network in different time periods.

 In addition to the BGP protocol described above, the dynamic routing protocol may be an OSPF (Open Shortest Path First) protocol, an ISIS (Intermediate System-Intermediate System) protocol, or a RIP (Routing Information Protocol). Routing Information Protocol).

 Step 230: When the network planning is adjusted, the user can adjust the established control policy as needed, so that the route dynamically changes with the new control policy.

 If the network planning is adjusted, the user only needs to adjust the established control policy to advertise the bearer of the route. For example, the dynamic routing protocol related settings mentioned here can be left unchanged. The route can be advertised according to the dynamic routing protocol according to the control policy, and the adjustment is automatically performed. , so that the new time policy is automatically executed.

 For the foregoing time policy application example, the user adjusts the established time policy and advertises the bearer of the route. The BGP protocol related settings can be left unchanged. The route advertisement dynamically changes according to the time policy, and the user's network time-sharing management purpose is realized.

 While the embodiments of the present invention have been described above, the described embodiments are merely for the purpose of understanding the invention and are not intended to limit the invention. Any modification and variation of the form and details of the invention may be made by those skilled in the art without departing from the spirit and scope of the invention. It is still subject to the scope defined by the appended claims.
