| 摘要: |
| EPON(以太无源光网)作为一种新的接入技术,利用VLAN(虚拟局域网)可以满足用户对多种业务的需求,同时也可优化网络性能和满足同一EPON系统多运营商接入的需求。本文首先介绍了EPON中交换芯片对VLAN的支持,接着从用户空间、内核空间和芯片驱动三个层面描述了VLAN的设计,从而实现VLAN的配置与动态管理。 |

| Abstract: |
| As a new access technology,EPON(Ethernet Passive Optical Network),not only meets multi-service requirement from subscribers via VLAN(Virtual Local Area Network),but optimizes network performance and multi-carrier access requirement at the same time.First,this paper introduces the ASIC in EPON supporting VLAN,then depicts three aspects of VLAN design: user space,kernel space and chip driver,consequently implements configuration and dynamic management of VLAN. |
