Network measurement method, device and system under internet protocol security (IPsec) mechanism

Abstract

The invention provides a network measurement method, a device and a system under an internet protocol security (IPsec) mechanism, and relates to the field of wireless communication. The network measurement method, the device and the system under the IPsec mechanism are used for resolving error generated by a network measurement because of the fact that receiving of a business data package is out of order under the IPsec mechanism. The network measurement method under the IPsec mechanism includes the steps: receiving conversation requesting information which comprises the quantity of IPsec data packages and sending time interval information; after a sending port establishing a conversation, receiving the IPsec data packages with measurement information; and conducting an error detection to the received IPsec data packages according to quantity and the sending time interval information in the received measurement information and the conversation requesting information. The network measurement method, the device and the system under the IPsec mechanism are used in the wireless communication.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a network testing method, device and system under the IPsec mechanism. Background technique [0002] After completing network planning and deployment, operators often pay more attention to subsequent network maintenance and fault location methods, such as link fault location, packet loss rate, delay, error and other parameter indicators. For the test method adopted on the IP layer, the IETF (Internet Engineering Task Force, Internet Engineering Task Force) standard specifically defines the IPPM (IP Performance Metrics, IP performance metrics, IP performance indicators) working group. IPPM is a set of protocol specifications defined by IETF. On the one hand, it defines the specific items of performance indicators and the definition of these performance items, and on the other hand, it defines the methods for measuring these indicators. [0003] The 3GPP (The 3rd Generation P...

Problems solved by technology

Therefore, if the security detection method is considered on the IP layer, it is necessary to process the maintenance and measurement after security encryption, because after the protection of IPsec is adopted, the interactive data flow between the base station and the security gateway must be transmitted in the form of encrypted messages , making it difficult to measure specific service data flows

[0004] The maintenance and measurement method for using the IPsec security tunnel to protect the transmission data flow is to use some OAM (Operation Administration and Maintenance, operation management and maintenance) packets to detect, because only business data is included in this OAM packet The information such as the number and size of flows cannot determine whether the OAM packet is out of order, so it is likely that there will be a measurement error caused by the out-of-order OAM data packet received by the IPsec receiver.
