  • Description

                       线卡---经纬纱均为股纱

    1.线卡类属于卡其织物,如果经向是线,纬向是纱,则称为半线卡;如果经纬向都是线,而不是纱,则称为全线卡。半线卡和全线卡的斜纹方向都是右斜。这是与纱卡的最大区别。全棉线卡和纱卡风格相似,均具有布面匀整光洁,质朴柔和,定型稳定,吸湿耐磨等特点,多为休闲裤选料,尤其是经过免熨烫处理后,柔软舒适、无折痕的特点更加突出,成为目前休闲类长短裤面料。

     2.线卡用于交换机、路由器或其它网络设备的访问线路与访问设备间的一种设备接口。具有多种速率的数字和模拟线卡,都可以用来连接电缆光纤线路。数字线卡主要为数据网络提供数据包转发、 ping 响应以及数据包分片等功能。线卡主要关注以下几个方面:

      3.如先进先出(FIFO)、MDRR(Modified Deficit Round Robin) 拥塞控制,如加权随机早期检测(WRED:Weighted Random Early Detection) 其它特性,如访问列表(ACLs:Access Lists)、承诺访问速率(CAR:Committed Access Rate)以及数据流统计。 每种数字数据包线卡可以分为三个主要部分:

      4.物理层接口模块(Physical Layer Interface Module) ― 属于硬件模块,用于终止物理连接(相关媒体、异步传输模式 ATM、SONET 上的数据包<POS:Packet-over-SONET>、以太网) 交换引擎(Switching Engine) ― 该转发引擎为从交换结构(Switching Fabric)到目的地上 LC 的传输过程预先提供了数据包。主要负责处理数据包的查找、改写、缓冲以及拥塞控制等操作。 交换接口(Fabric Interface) ― 交换接口 ASIC(FIA)为从交换结构(Switching Fabric)到目的地上 LC 的传输过程预先提供了数据包。其主要负责交换授权请求、交换排队、组播复制等操作。
