Embodiment 1

[0135] In this embodiment, the access network side equipment includes BRAS, and the core network side equipment includes metropolitan area core network equipment, provincial core network equipment, and backbone network equipment. In this embodiment, in the mobile communication network system, the method for monitoring the uplink traffic array of the device port of the mobile communication network system, such as Figure 5 Shown, including:

[0136] Step 501: The access network side device judges the service type according to the access port of the service in the data stream.

[0137] Step 502: The access network side device fills in the last three bits used to characterize the service type in the DSCP in the data stream according to the three binary numbers corresponding to the service type, and sends the data stream corresponding to the filled DSCP to Core network side equipment.

[0138] Step 503: The core network side device receives the data stream sent by the access side device...

Embodiment 2

[0146] In this embodiment, the access network equipment includes BRAS and domain core network equipment, and the core network equipment includes urban and provincial core network equipment and backbone network equipment. In a mobile communication network system, a method for monitoring the downlink flow array of the device port of the mobile communication network system. Such as Image 6 Shown, including:

[0147] Step 601: The border router determines the service flow direction according to the access port of the service in the data flow.

[0148] Step 602: The border router fills in the first three bits of the DSCP in the data stream to characterize the service flow direction according to the binary number corresponding to the preset service flow direction, and sends the data flow corresponding to the filled DSCP to the metropolitan area. Backbone network equipment.

[0149] Step 603: The metro core network device associates different service types with different BGP routing comm...

Abstract

The invention provides port uplink and downlink traffic array monitoring methods, devices and systems. The port uplink traffic array monitoring method comprises the following steps: core network side equipment receives a data flow sent by access network side equipment, wherein the DSCP in the data flow is used for characterizing that the bit of the service type is filled in by the access network side equipment according to the binary number corresponding to a preset service type; the bit, used for characterizing the service flow direction, in the DSCP of the data flow is filled in according to the determined flow direction of service in the data flow and the binary number corresponding to a preset service flow direction; and when a request for acquiring port uplink traffic array information is received, the filled-in DSCP in the data flow flowing through a port at the current moment is sent to network management equipment in order to enable the network management equipment to monitor the port uplink traffic array according to the filled-in DSCP. Port traffic array monitoring can be realized without additionally deploying DPI equipment.

Description

Technical field [0001] The present invention relates to the technical field of network communication, and in particular to a method, device and system for monitoring the uplink and downlink flow arrays of ports. Background technique [0002] There are multiple communication system (network) operators, including communication systems of mobile operators, communication systems of China Unicom operators, and communication systems of telecommunication operators. Each communication system includes multiple types of services, such as broadband services and mobile phone users. Internet business, etc. [0003] No matter which operator's communication system, its network traffic is forwarded through routing tables and network device ports. [0004] The network management system outside the communication network can obtain port traffic of network devices (such as switches, routers, etc.) in the communication system through SNMP (Simple Network Management Protocol) and MIB (Management Informan...
