Point-to-point protocol Van Jacobson (VJ) packed data reduction method

Abstract

The invention provides a point-to-point protocol Van Jacobson (VJ) packed data reduction method which aims at solving the problem in the prior art of potential safety hazards and the like on the stability of a system, wherein the problem is caused by increasing of system collecting ports and repeated collecting total flow when signaling data is collected and analyzed from an R-P port and simultaneously business data is collected and analyzed from a port Pi between a packet data support node (PDSN) and the internet. Point-to-point PPP data is collected from the R-P port, and a mapping relation table among a connective number, a generic routing encapsulation protocol (GRE) Key, a GRE lower layer source internet protocol (IP), a GRE lower layer destination IP, a PPP upper layer source IP, a PPP upper layer destination IP, a source port number and a destination port number. The connective number, the GRE Key, GRE lower layer source IP and the GRE lower layer destination IP are combination index keys. The point-to-point protocol VJ packed data reduction method has the advantages of being capable of collecting the PPP data at the R-P port and achieving monitoring and analysis of the signaling and business data simultaneously, enabling network monitoring results to be close to reality and be representative.

Description

[0001] technical field [0002] The invention relates to the technical field of network monitoring of the third-generation mobile communication system, in particular to a point-to-point protocol VJ compressed data recovery method in the third-generation mobile communication system. Background technique [0003] CDMA 2000 1x / EV-DO is one of the third-generation mobile communication standards (hereinafter referred to as C network), and C network is divided into circuit domain CS (hereinafter referred to as CS) and packet domain PS (hereinafter referred to as PS), CS provides voice services and low-speed data services, and PS provides high-speed Internet services. With the increasing popularity of data services, the traffic growth rate exceeds 100% every year. Therefore, the monitoring of PS network quality and service content in the packet domain and traffic analysis are getting more and more attention from operators. [0004] The R-P interface is the core network interface o...
