作为光纤接入的重要组成部分,高性能的光纤转换器的地位日益突出。长城网络新近推出的GEC-2500M 光纤转换器10/100M 自适应模块,内置一块两端口的高放交换芯片,采用存储转发机制,除提供以太网光电转换外,还在网络传输效率,可靠性方面有了提高。该芯片的功能主要有:能够隔离冲突:当用户的以太网段上产生侦听用数据包和发生冲突的数据包时,可以直接处理侦听包和发生冲突的数据包,决定应答还是抛弃,保证接入交换机收到有效负载,从而提高了网络的传输效率;能够隔离广播:用户段内部进
As an important part of fiber access, high-performance optical fiber converter has become increasingly prominent. Great Wall Network recently introduced GEC-2500M optical fiber converter 10 / 100M adaptive module, built-in a two-port high-density switching chip, using storage forwarding mechanism, in addition to providing Ethernet optical conversion, but also in the network transmission efficiency and reliability Have improved. The chip’s main functions are: to be able to isolate the conflict: When the user’s Ethernet segment to generate a packet with the packet snooping and conflict, you can directly deal with the packet sniffing and conflict, decided to answer or abandon, To ensure that the access switch receives the payload, thus improving the network transmission efficiency; to be able to isolate the broadcast: the user segment internal
