Problems solved by technology

[0014] Since layer 4 and layer 5 are oriented to the flow of the application layer, by adding sequence numbers in layer 4 and layer 5, only the packet loss of the application layer flow can be obtained, but the packet loss of the IP link cannot be obtained

Embodiment Construction

[0038] Embodiment 1 of the present invention provides a method for measuring IP link packet loss, as shown in Figure 1, comprising the following steps:

[0039] Step s101, the receiver device receives a delimited packet from the sender device, the delimiter packet carries the number of IP data packets sent by the sender device, and the number is the number of IP data packets sent by the sender device before sending the delimiter packet.

[0040] The specific implementation process includes: the sending end device sends a delimitation packet to the receiving end device according to a preset statistical cycle. The delimited packet carries information such as the packet sequence number and the number of IP data packets sent by the sending end device, for example: the number of IP data packets sent in the previous one or more statistical periods, or the total number of IP data packets sent cumulatively. When a sending device needs to send IP data packets to multiple receiving devi...

Abstract

The invention discloses a method for measuring an IP link loss situation. The invention comprises the following steps that a bound packet from a sending end equipment is received; IP data packet number from the sending end equipment is carried in the bound packet; the received IP data packet number is calculated with statistics; the IP link loss situation is determined by the comparison between the received IP data packet number and the IP data packet number in the bound packet. The invention also discloses an equipment for measuring the IP link loss situation. The implementing case of the invention determines the IP data packet number, which is supposed to be received through sending the bound packet and compares the number with the actually received IP data packet number, thereby acquiring the IP link loss situation.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and equipment for measuring IP link packet loss. Background technique [0002] Multiple interfaces are included between network elements of the radio access network, such as: Abis and A3 / A7 interfaces of the CDMA (Code Division Multiple Access) 2000 network, and Iub and Iur interfaces of the WCDMA (WidebandCDMA, broadband CDMA) network. interface etc. Among them, the Abis interface in CDMA 2000 is used to connect BTS (Base Transceiver Station, base station) and BSC (Base Station Controller, base station controller); the A3 / A7 interface is used to connect BSC and other BSCs. The Iub interface in WCDMA is used to connect RNC (Radio Network Controller, radio network controller) and NodeB (base station); the Iur interface is used to connect RNC with other RNCs. [0003] The transmission bearer mode of the wireless access network is gradually evolving towards IP. ...
