Quintuple bill synthesis method and device in asymmetric condition

Abstract

The invention discloses a quintuple bill synthesis method and a device in the asymmetric condition, which solves the following technical problems in the prior art: due to the current routing strategy, uplink and downlink messages are transmitted through different links; when the outlets of two links occur in different machine rooms, only uplink messages or only downlink messages reach DPI equipment; the single acquisition of a dialog is adverse in effect and a portion of the service information is not full; time delay indexes cannot be calculated, and some services cannot be accurately identified. According to the invention, the quintuple bill synthesis method in the asymmetric condition comprises the steps of feeding the bidirectional messages of a quintuple into same telephone bill collecting and processing terminal through mirror messages mirrored by DPI equipment in the same machine room, outputting symmetric telephone bills for treatment, and subjecting all telephone bills in a large data platform to merging treatment with the quintuple as a Key.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for synthesizing five-tuple CDRs under asymmetric conditions. Background technique [0002] DPI (Deep Packet Inspection) equipment detects and analyzes the traffic and message content at key points of the network, and can filter and control the detection traffic according to a pre-defined strategy, and can complete the fine-grained identification and service flow of the link. Flow analysis, business traffic proportion statistics, business proportion shaping, application layer denial of service attacks, filtering of viruses and Trojans, and control of abuse of P2P. Unified DPI refers to a set of DPI equipment that collects and recognizes the traffic on the link, and distributes the traffic or analysis statistics required by other systems to the third-party application system servers. All kinds of traffic management-related application systems in the netwo...

Problems solved by technology

[0005] The embodiment of the present invention provides a method and device for synthesizing quintuple bills under asymmetric conditions, which solves the current situation that due to routing strategies, uplink and downlink messages are transmitted through different links. When exporting to different computer rooms, the packets arriving at the DPI device will only have uplink packets or only downlink packets, which will cause adverse effects on dialog ticket collection, incomplete information on some services, inability to calculate delay indicators, and inaccurate accuracy on some services Identify technical issues
