Description: "Ethernet in the First Mile" (EFM) is an upcoming standard currently being drafted by the 802.3ah task force in the IEEE organization. One of the tracks in the standard deals with Ethernet over Passive Optical Network (EPON), a centralized point-to-multi-point network with a shared upstream channel. This paper deals with the problem of upstream bandwidth allocation in EPON networks. We suggest, analyze, and compare several bandwidth allocation algorithms. As a novel type of network, EPON presents many new challenges, and one of the main goals of this project was to get a feel for the network in order to decide on the next steps in its exploration. To that end, we have constructed an OPNET model of an EPON network based on the IEEE - "Ethernet in the First Mile" (EFM) is an upcoming standard currently being drafted by the 802.3ah task force in the IEEE organization.

Description: 802.3ah 协议的英文原文。IEEE 802.3ah 负责制定的 APON 是由 FSAN/ITU 定义，以 ATM 协议为载体，下行以 155.52Mbps 或 622.08Mbps 的速率发送连续的 ATM 信元，同时将物理层 OAM 信元插入数据流中；上行以突发的 ATM 信元方式发送数据流，并在每个53字节长的 ATM 信元头增加3字节的物理层开销，用以支持突发发送和接收。
-802.3ah the original English text of the agreement. APON is the IEEE 802.3ah responsible formulated defined by FSAN/ITU, the ATM protocol for the carrier, a downlink ATM cells in order to send a continuous rate of 155.52Mbps or 622.08Mbps, while the physical layer OAM cell is inserted into the data stream uplink The burst of ATM cells transmit data streams, and physical layer overhead increase of 3 bytes in each ATM cell header is 53 bytes long, to support the burst transmission and reception.
