Problems solved by technology

[0005] 1. Analyzing the accuracy, Netflow sends flow information by the switching device, but the main function of the switching device is data exchange. Therefore, when the switching traffic is large, the switching device sends flow data by sampling in order to ensure the exchange of data, and the data cannot be guaranteed to be complete. ;
[0006] 2. The device needs to support Netflow. Netflow was invented by Cisco, so it is mainly supported by Cisco routers at present, but if some routers want to support Netflow function, they need to purchase additional support modules, and the standards are not consistent with other domestic switching devices;
[0007] 3. Application performance analysis cannot be performed. Since Netflow only sees flow log information, there is no way to analyze whether performance parameters such as data transmission path and response time are abnormal.

Embodiment 1

[0022] The embodiment of the present invention provides a device for diagnosing MPLS-VPN data packets, specifically as figure 1 As shown, the device is independent of the router and connected to the router. The device includes: a data collector 10 and a processor 20 .

[0023] The data collector 10 is configured to collect all MPLS data packets forwarded by the current router.

[0024] The processor 20 is configured to analyze the MPLS data message and determine whether the relevant parameters corresponding to the MPLS data message are abnormal, wherein the relevant parameters corresponding to the MPLS data message include at least one or more of the following: MPLS data message The actual destination router reached during transmission, the actual response time corresponding to the MPLS data packet, the transmission protocol actually followed during the transmission of the MPLS data packet, the actual source address of the data transmission, the actual destination address, th...

Embodiment 2

[0027] On the basis of the foregoing embodiments, when the relevant parameters corresponding to the MPLS data message include: the MPLS data message transmission path, the processor 20 is specifically used for:

[0028] Analyze the service type of the MPLS data message and the actual destination router that the MPLS data message reaches when it is transmitted. Then, according to the service type of the MPLS data message and the pre-stored BGP router protocol, match the preset target router that the MPLS data message arrives at when it is transmitted. The BGP router protocol here is actually the data collected and stored by the data collector when the collection device is just turned on.

[0029] According to the service type of the data message, it can be determined that in the BGP router protocol, the next target router (Router Target, RT for short) to which the data message should be transmitted, that is, the target router. However, when analyzing the data packet, it is pos...

Embodiment 3

[0057] In addition, the embodiment of the present invention also provides a computer-readable storage medium, on which computer program instructions are stored, and when the program instructions are executed by the processor 20, the device steps of the above-mentioned embodiment 1 are implemented.

Abstract

The invention discloses a device for diagnosing MPLS-VPN data messages. The device includes: the device is independent of the router and connected to the router, including: a data collector, which is used to collect all multi-protocol label switching MPLS packets forwarded by the current router. A data message; a processor, configured to analyze the MPLS data message and determine whether the relevant parameters corresponding to the MPLS data message are abnormal. The device for diagnosing MPLS-VPN data packets is independent of the router, it can be set flexibly, and does not depend on the model and function limitations of the router. Moreover, data packets can be collected in real time to ensure the integrity of the data packets. In addition, data packets can be analyzed anytime and anywhere to determine whether the relevant performance parameters corresponding to the data packets are abnormal, and general operation and maintenance personnel can take effective measures in a timely manner.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a device for diagnosing MPLS-VPN data messages. Background technique [0002] At present, MPLS VPN is an IP-VPN based on MPLS technology. It applies MPLS technology to network routers and switching devices to simplify the router selection method of core routers. It can be used to construct intranets and extranets, and can meet various flexible requirements. The transmission system required by the business configuration. [0003] For traffic analysis of MPLS VPN, Netflow analysis device is usually used. Netflow technology was first invented by Darren Kerr and Barry Bruins of Cisco in 1996. Netflow is mainly used for proprietary network devices (routers) to accelerate data exchange, and can simultaneously implement high-speed forwarding of IP data streams (Flow) A technique for making measurements and statistics. [0004] Using Netflow technology for MPLS VPN analysis ma...
