Thread card --- warp and weft yarn are all stranded yarn

 1. Thread cards belong to khaki fabrics. If the Longitude direction is a thread and the latitude direction is a yarn, they are called half-thread cards. If the longitude and latitude direction are all threads, instead of yarn, they are called full-thread cards. ban xian ka and quan xian ka twill the direction is right oblique. This is twill the biggest difference. The style of all-cotton line card is similar to that of yarn card, both of which have the characteristics of uniform and smooth cloth, plain and soft texture, stable shaping, moisture absorption and wear resistance. Most of them are casual pants, especially after ironing-free, soft and comfortable, the characteristic of non-creasing is more prominent, and it has become the preferred fabric for casual long shorts.

 2. The line card for a switch, router or a device interface between the access line of other network devices and the access device. Digital and analog line cards with multiple rates can be used to connect cable or optical fiber line. Digital line cards provide data packet forwarding, ping response, and packet sharding for data networks. Line cards mainly focus on the following aspects:

 3. Such as FIFO and MDRR congestion control, such as weighted random early detection ( WRED: Weighted Random Early Detection) other features, such as Access list (ACLs:Access Lists) and guaranteed Access rate ( CAR: Committed Access Rate) and data stream statistics. Each digital packet line card can be divided into three main parts:

 4. Physical Layer Interface Module (Physical Layer Interface Module) is a hardware Module used to terminate Physical connections (related media, asynchronous transmission mode ATM, SONET  on the data packet <POS:Packet-over-SONET>, Ethernet) Switching Engine-the forwarding Engine is the Switching Fabric data packets are provided in advance during the LC transmission process to the destination. Processes data packet search, rewriting, buffering, and congestion control. Exchange Interface (Fabric Interface)-The exchange Interface ASIC(FIA) provides data packets in advance for the transmission process from the switch Fabric to the LC on the destination. It is mainly responsible for the exchange of authorization requests, exchange queuing, multicast replication, and other operations.
