Embodiment Construction

[0029] The network address translation equipment among the present invention comprises the network address translation / network address port translation (NAT / NAPT) equipment used for intercommunication between private network and public network, and the network address translation-protocol used for IPv4 network and IPv6 network intercommunication Translation (NAT-PT) device. In this embodiment, the present invention is described in detail by taking passive measurement of network performance in a private network and a public network environment with NAT devices as an example.

[0030] The NAT device is used to translate the internal IP address used in the internal network into a legal external IP address for use on the Internet. There are three types of NAT: static NAT (staticNAT), NAT pool (pooledNAT, also called dynamic NAT) and NAPT. Static NAT is the easiest to set up. Each host in the internal network is permanently mapped to a legal address in the external network; a NAT ...

Abstract

The invention discloses a network performance measurement method to solve the problem of available technologies that the same measured stream can't be positioned at both sides of switching equipment due to the changing of network address, and unable to fulfill the reactive measurement for the network performances; this method may obtain the measured stream network address binding relationship from the network address switching device, and configure the measured stream description and the network address binding relationship to the measurement point; the measurement point may extract the objective message of measured stream, and generate the conformable message identifier for the same message for different measurement point with the network address binding relationship, and generate the message abstract data according to the stream identifier and message identifier and submit; calculate the relevant network performance indexes according to the message abstract data submitted from the measurement point. The invention may still disclose a network system.

Description

technical field [0001] The invention relates to measurement technology in the communication field, in particular to a network performance measurement method and system. Background technique [0002] With the rapid development of Internet (Internet) technology and network services, users' demand for network resources has increased unprecedentedly, and the network has become more and more complex. The ever-increasing network users and applications lead to heavy network load and overloading of network equipment, resulting in network performance degradation. This requires extraction and analysis of network performance indicators to improve and improve network performance. Therefore, network performance measurement emerges as the times require. Discover network bottlenecks, optimize network configuration, and further discover potential dangers that may exist in the network, manage network performance more effectively, provide verification and control of network service quality,...
