The design of an ASIC, which is capable of connecting multiple Ethernets by SDH links through complex network topology, is given here. A closed-loop congestion control mechanism over the entire network is put forward, a scheduling algorithm for traffic of four differenct priorities is suggested and the requried buffer size under self-similar traffic is calculated.

The structure of a chip, which maps 10/100 Mbit/s Ethernet fames into SONET/SDH virtually concatenated VC-12 payloads, is put forward. The required link capacity to satisfy the desired QoS is calculated. A closed-loop flow control mechanism for both local and remote ends is suggested and the buffer size under self-similar traffic is estimated

An algorithm to improve the bandwidth utilization for EPON by using dynamic bandwidth distribution is put forward. System performance, such as queuing delay under self-similar traffic, is simulated by using OPNET.

As is known, SDH has become the backbone of today's communication networks. Meanwhile, Ethernet remains the dominating technology in LAN (Local Area Network) for data transmission. Therefore, how to exchange data among separate 10M/100M Ethernets over SDH has become very attractive. This paper gives a single chip solution, which provides an interface between a 10M/100M Ethernet and N E1 links (or a high-speed link) and consequently transmits the inter-Ethernet frames onto the backbone. In addition, this paper sets up the queueing model for the buffer and analyzes the performance of FIFO under self-similar traffic. Also suggestions on congestion control are given.
