校园网宽带接入设备的稳定性对于整个网络系统的稳定与业务至关重要,为了确保校园网宽带接入设备的稳定运行,通常采用传统的冗余备份技术,然而这些技术需要复杂的配置而且存在不同的局限性.文中比较了PADO DELAY、冗余TRUNK和虚拟化技术三种冗余备份技术的优缺点,结合学校实际,采用了网络宽带接入设备的虚拟技术,将多台在软硬件相似的网络核心设备结合在一起,虚拟成一个设备,从而使网络配置问题大大简化,而且从系统架构的高度根本上解决了上网用户状态的热备份需求.
校園網寬帶接入設備的穩定性對于整箇網絡繫統的穩定與業務至關重要,為瞭確保校園網寬帶接入設備的穩定運行,通常採用傳統的冗餘備份技術,然而這些技術需要複雜的配置而且存在不同的跼限性.文中比較瞭PADO DELAY、冗餘TRUNK和虛擬化技術三種冗餘備份技術的優缺點,結閤學校實際,採用瞭網絡寬帶接入設備的虛擬技術,將多檯在軟硬件相似的網絡覈心設備結閤在一起,虛擬成一箇設備,從而使網絡配置問題大大簡化,而且從繫統架構的高度根本上解決瞭上網用戶狀態的熱備份需求.

The stability of the broadband access network equipment in campus is essential for the stability of the entire network system and business,in order to ensure the stable operation of the network of broadband access equipment in campus,usually adopt the traditional re-dundant backup technique,however,these techniques require complex configuration and have different limitations. It compares the advan-tages and disadvantages of the PADO DELAY,redundant TRUNK and virtualization technology,three redundant backup technology. Combined with the actual school,use virtual technology for broadband access network equipment,multiple hardware and software similar to the core of the network equipment will be combined into a virtual device,which greatly simplifies network configuration and from the system architecture of a high degree solves the hot backup needs of Internet users state.
