Network Structure In IP Over WDM And Pretection Mode Research

In order to adapt the development of operation network, this article would aim to simplify the network layer, decrease the overlapping function and save investment. Furthermore, we try to achieve the combination between IP grouping transform technique and light network transform technique, and research the evolvement policy for the intra-province main stream and the urban transform network's core layer. We also perform the test and verification to instruct the intra-province and urban network's construction.The article includes following contents:(1) In IP over WDM mode, analysis and compare the techniques and applications of the framework and protect mode with multiple company's WDM system, research the IP over WDM's framework mode for second province main stream and urban core layer.(2) Analysis the multiple system protection mode among multiple WDM's mixture network, research the requirement for above protection mode.(3) Analysis the IP network's framework and protection mode, and research the cooperative protection pattern between IP and WDM layer.(4) Perform test to verify the IP over WDM framework and the cooperative protection pattern between IP and WDM layer.
