Description: 摘要：基带传输与同轴网络。
随着运营商带来经济效益和社会效益。
从技术上讲有三种方式突破接入网瓶颈，一是甚高速数字用户线路(VDSL)；二是基于无源以太网的无源光网络技术，继承了以太网的低成本和易用性以及光网络的高带宽，是实现FTTH众多技术中性价比最高的一种。随着EPON国际标准——IEEE802.3ah在2004年正式发布，EPON的产业联盟已经吸引了众多厂商的积极参与，从EPON的核心芯片、光模块到系统，EPON的产业链已经日趋成熟。
-Abstract: The base-band transmission and coaxial networks. As the operators bring economic benefits and social benefits. Technically speaking there are three ways to break through bottlenecks in the access network, first, even the high-speed digital subscriber line (VDSL) 2 is based on passive Ethernet passive optical network technology, inherited the low cost and ease of use of Ethernet as well as the high-bandwidth optical networks is to achieve cost-effective FTTH technology, the highest number of one. With the EPON international standards- IEEE802 .3 ah in 2004, released, EPON industry alliance has attracted the active participation of many companies, from the core of EPON chips, optical modules to the system, EPON of the industry chain is becoming more mature.

Description: Optical Burst Switching (OBS) network is seen as a promising solution as it directly transports Internet-Protocol over Wavelength Division Multiplexing (IP over WDM) networks. OBS network uses a one-way resource reservation mechanism to set up the resources for each data burst transmission. Therefore, the performance of OBS networks depend on contention resolution strategies to reach acceptable levels for bandwidth utilization efficiency. This paper proposes the use of burst segmentation as a proactive contention resolution technique at ingress nodes of OBS network as well as reactive contention resolution policy at core nodes for reducing the probability of burst drop in the network in order to increase the performance of the network. -Optical Burst Switching (OBS) network is seen as a promising solution as it directly transports Internet-Protocol over Wavelength Division Multiplexing (IP over WDM) networks.
