1. Research of Routing Protocol
It is a fundamental principle of network
that high network performances rely on appropriate application of route protocol.
Route protocols are important components of the computer network because they
determine the network resources are used efficiently and network robustness is
maintained. Our research approach focuses on how to choose one kind of route protocol
that is adapt to a network, how to compare the characteristic of different route
protocols such as the difference between OSPF and IS-IS, how to Obtain performance
data for the route protocol, and so on. We use OPNET to simulate and analyze these
projects and we have obtained many good results. This
project is going on with the development of difference routing protocol.We plan
to continue to do with it in this year. 2.
Research of Traffic Analysis
In today's rapidly
evolving networking environment, increasingly more mission critical traffic is
transported over network, so traffic engineering and traffic analysis are the
key to achieve mission critical networking. Our applications of OPNET also care
the ability to efficiently map traffic onto a network topology model as to get
factors of optimizing the utilization of network resources. And we have explored
the methods of using OPNET to simulation the MPLS network and importing the MPLS
traffic into the OPNET to found traffic model, These tasks can be accomplished
by great effort and simulation of OPNET. We
are planning to buy the new license of MPLS and after that,we are going to research
it in these 2 years. 3.
Research of IP Multicast
IP Multicast routing
protocols generally follow one of two basic approaches, depending on the expected
distribution of multicast group members throughout the network. OPNET can support
the PIM-SM, but commonly IP multicast routing protocols used in all kinds of network
include CBT, PIM-DM, DVMRP. Now our research group are interested in developing
and implementing different IP Multicast routing protocol for OPNET multicast research,
it can help us know more about the essential of application of higher level protocols
used with IP Multicast and create new way to develop protocol. Now
we are researching Multicast,perhaps in this year we can obtain some good results
about it. 4.
Research of Web Service Performance
Internet
in China has developed very quickly . People are using Internet and web-based
services as a primary means for conducting business. Services such as e-mail have
become critical to communication within and across organizations. As reliance
on these services increases, so do customers expectations for availability, reliability,
and responsiveness of the services. But the current situation of the networking
is not satisfying. Customers always complain about the poor performance of the
networks. There are three factors affecting the performance of web service: network
performance, server processing ability and protocols in use. What we are doing
now is to study how these three factors affect the performance of web service
and then to find out methods to improve the service performance by changing the
three factors. By
now we have done a lot of study on the protocol factor and we are going to pay
more attention to study any other factors affected the performance of web service.
