Specific descriptions based on embodiment described in Fig. 1 and Fig. 2, refer to Fig. 3, Fig. 3 be the present invention based on
The network quality evaluating method one embodiment schematic flow sheet of bypass；As it is shown on figure 3, base of the present invention
Network quality evaluating method in bypass comprises the following steps:
Between step S01, primary nodal point and secondary nodal point in network link, bypass observation station is set.
When network quality is evaluated and tested, can set between any two node in network link
Put bypass observation station；Such as, in the application scenarios shown in Fig. 1, can be at client and router
Between bypass observation station is set, can be to arrange bypass observation station between router and service end, also

Observation station；The present embodiment specifically arranges position to bypass observation station and specifically arranges number and do not do
Limit, it will be understood to those skilled in the art that in concrete network design, bypass observation
Point can the most arbitrarily be arranged.
Step S02, when described primary nodal point and secondary nodal point carry out data interaction, the number of recording interactive
Arrive the time of described bypass observation station according to bag, and obtain described primary nodal point respectively to described side
Second net of the first network time delay of road observation station and described bypass observation station extremely described secondary nodal point

It will be understood to those skilled in the art that from the statistic of network packet, TCP(Transmi
Ssion Control Protocol, transmission control protocol) most ack(ackno
Wledgement character, confirms character) reply bag, the master that its service end self produces
Machine time delay, much smaller than network delay, negligible；For small part owing to " TCP time-out is fixed
Time device wait ", and the service end time delay produced is bigger
Bag, can be eliminated by statistic sampling.Meanwhile, TCP three-way handshake process do not exist "
TCP overtime timer waits ", suitably increase the time delay proportion of the packet of TCP handshake procedure,
Reduce the time delay proportion of general data bag, also make network delay more accurate.

To the packet of service end through bypassing the moment T1 of observation station, the number of responses responded to service end
The time that consumed of moment T2 again passing by bypass observation station according to bag ack (ignores service end self
The time delay produced), it is simply that the distance of bypass observation station to service end comes and goes time-consuming A, divided by 2 i.e.
Can obtain servicing side propagation delay time t1, i.e. t1=(T2-T1)/2=A/2.Because, service end
The time delay self produced is compared with network delay, and the time is the shortest, is negligible, and logical
In the case of Chang, response data packet ack that service end produces is all instant reply.Likewise it is possible to
Calculating PC to the network bypassing observation station is time-consumingly PC side propagation delay time t2, i.e. t2=(T3-
T2)/2=B/2.

As a example by the concrete application scenarios that a bypass observation station is set between client and service end,
Refer to Fig. 5, Fig. 5 is in present invention network quality evaluating method based on bypass, obtains bypass
Observation station and the schematic diagram of corresponding node data retransmission rate；As it is shown in figure 5, when client sends number
During according to bag to service end, bypass observation station can be got to the number of service end in bypass observation station
According to bag retransmission rate, because in bypass observation station it can be seen that all observation stations are to the path of service end
On the packet lost, the packet of the most original transmission and the re-transmission bag resend can be seen
Examine and obtain.But do not observe the packet that client is lost to bypass observation station, because this
If section lost data packets, bypass observation station can only see the packet after re-transmission, it is impossible to accurately
Judge whether re-transmission occurred.Same reason, can issue client by observing service end
The packet of extreme direction, obtains the packet of original transmission and resends
Retransmit bag, such that it is able to obtain the client retransmission rate to bypass observation station path.
