All-optical switch with double switched ports based on semiconductor optical amplifier 基于半導(dǎo)體光放大器的雙端口全光光開關(guān)
The network engineer uses a portable integrated analyzer to drill into the switch and view the activity on each switch port 網(wǎng)絡(luò)工程師使用便攜式集成分析儀深入交換機觀察每一個交換機端口上的活動情況。
Layer 2 switches can improve performance by dividing lans into smaller segments and by providing dedicated connections between workstations and switch ports for high-power users 第二層交換機通過把局域網(wǎng)分成小段并為實力強大的用戶提供工作站與交換機端口之間的專用連接而提高了性能。
You can connect an ethernet hub into a switch port and then connect multiple ethernet hosts into the hub, but you can't mix token ring hosts in with the ethernet gang on the same segment 這段話好像是說不能在同一個借口上連接不同的網(wǎng)絡(luò)類型,那交換機能不能在一個接口連接以太網(wǎng),在另外一個接口連接令牌環(huán)?
The other one is pppoe ( point-to-point protocol over ethernet ), which is fit for adsl ( asymmetric digital subscriber line ) users . we succeeded in the control of the switch ports and the traffic accounting under dhcp mode, and in the user's authentication, authorization and accounting under pppoe mode 本文給出了在寬帶網(wǎng)上采用radius(遠程撥號用戶認證服務(wù))協(xié)議結(jié)合pppoe(以太網(wǎng)上的點對點協(xié)議)實現(xiàn)用戶鑒別、授權(quán)和計費管理的解決方案和實現(xiàn)方法。
This paper gives the general design of the administration system in the broadband man . it also explains the detail implementation, such as the modules of the traffic accounting and radius ( remote authentication dial in user service ) programs, the control of the layer 2 switch ports, the distribution of ip address, and so on . during the building of the system, we greatly unproved the efficiency of snmp ( simple networks manage protocol ) trap and achieved the access control hi the broadband man 對以太網(wǎng)方式接入的用戶,利用802.1q、pvlan(私有虛擬局域網(wǎng))等新技術(shù)實現(xiàn)了用戶數(shù)據(jù)隔離和安全性保證,并對用戶端口資源進行了統(tǒng)一管理和遠程自動控制,采用snmp(簡單網(wǎng)絡(luò)管理協(xié)議)采集端口流量的方式實現(xiàn)了以太網(wǎng)用戶的按流量計費,詳細設(shè)計了具體的流量采集程序模塊組成和各部分的功能。
