With the rapid development of the IP networks, the Optical Transport Network (OTN) andPacket Transport Network (PTN) become the two trends in the core networks, aggregationnetworks and access networks. Deploying networks at different levels can not only make use ofbig OTN containers to implement grooming of high granularity traffic, but also take advantageof the PTN

As the combination of Ethernet and Passive Optical Network technology, EPON has the same advantages of high bandwidth and passive components in PON. Meanwhile, there is no protocol conversion needed between EPON and the Ethernet device. EPON is universally viewed as the most appropriate solution to access network bandwidth bottleneck. How to allocate the bandwidth

With the expansion of services offered over the Internet, a dramatic increase of bandwidth has been facilitated both in the metro core network and the subscriber side. This results in a growing gap between the capacities of the core and local networks and the much lower capacities of the access networks inbetween, the so-called “first
