Abstract
Day by day Internet communication and services are experiencing an increase in variety and
quantity in their capacity and demand. Thus, making traffic management and quality of service
(QoS) approaches for optimization of the Internet become a challenging area of research;
meanwhile flow control and congestion control will be considered as significant fundamentals
for the traffic control especially on the high speed Metro Ethernet.
IEEE had standardized a method (IEEE 802.3x standard), which provides Ethernet Flow
Control (EFC) using PAUSE frames as MAC control frames in the data link layer, to enable or
disable data frame transmission. With the initiation of Metro Carrier Ethernet, the conventional
ON/OFF IEEE 802.3x approach may no longer be sufficient. Therefore, a new architecture and
mechanism that offer more flexible and efficient flow and congestion control, as well as better
QoS provisioning is now necessary.
