Embodiment 1

[0140] Compared with Embodiment 1, the control device in this embodiment can simplify the algorithm for calculating packet loss.

[0141] For ease of understanding, a practical application scenario is used below to describe the packet loss statistics method of the embodiment of the present invention.

[0142] Such as image 3 as shown, image 3 It is a schematic structural diagram of an embodiment of a transmission path of a target service flow. The user configures the characteristic value of the target service flow on the control device 30 . The control device 30 acquires the transmission path to the target service flow according to the characteristics of the target service flow. On the transmission path, the IP packet of the target service flow is sent from the origin 38 to the fragmentation device 32 after passing through the source edge device 31 . The IP packet is fragmented by the fragmentation device 32, and different fragments are respectively sent from the first p...

Abstract

The embodiment of the invention discloses a packet loss statistics method, a control device, a fragmentation device and a reassembly device. The method in the embodiment of the present invention includes: the control device obtains the source border device, fragmentation device, reassembly device, and destination border device of the target service flow in the network topology; the control device obtains the IP packet of the target service flow sent by the source border device obtain the number of IP packets of the target service flow received by the destination border device; obtain the number of IP packets received by the fragmentation device for the target service flow, the number of IP packets expected to be fragmented, and the number of IP packets sent Quantity; obtain the number of IP packets received by the recombination device for the target service flow, the number of IP packets expected to be reassembled, and the number of IP packets sent; the control device calculates the target service flow according to the obtained data. The number of dropped packets on the path. The embodiment of the present invention can realize statistics on packet loss of fragmented messages in communication transmission.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for counting packet loss, a control device, a fragmentation device and a reassembly device. Background technique [0002] In the existing physical network, the length of the data frame is limited, and the upper limit of the length of the data frame in the physical network is called the maximum transmission unit (English: maximum transmission unit, abbreviation: MTU) of the physical network. For the MTU, the Internet Protocol (English: Internet Protocol, abbreviation: IP) adopts a strategy of fragmentation and reassembly. [0003] In this fragmentation and reassembly strategy, when an IP packet enters a new network, if the length of the IP packet is greater than the MTU of the network and cannot be encapsulated into a frame, the IP packet will be divided into several lengths less than Fragmentation of the MTU of the network, and each fragmentation is encapsulated ...
