  Computer network tends to be subjected to the proliferation of mobile demands
and increasingly multifarious, therefore it poses a great challenge to
guarantee the quality of network service. By designing the model according to
different requirements, we may get some related indicators such as delay and
packet loss rate in order to evaluate the quality of network service and verify
the user data surface and capacity of the network environment. In this paper,
we describe an analytical model based on the measurement for the delay of each
packet passing through the single existing routers in the network environment.
In previous studies, the emulation of real network service behaviors was
generally under ideal condition. In our work, the test environment is built to
get the relevant test results of the actual network, and the corresponding
theoretical results are obtained by our model. The test results are compared
with the theoretical results, analyzed and corrected, in order to verify the
feasibility of our analysis model for the performance analysis of the actual
network. With this concern, calculation results are modified with different
schemes to realize more precise calculation of delay boundary with the
comparison with the experimental test results. The results show the analysis
methods after the amendment can realistically estimate the performance of
network element.
