Requests result in the fax pages being delivered to the chosen fax and the subscriber charged a fee. Typical applications of FDDI are in the area of high speed LAN backbones. This lets the file server regulate communications among the workstations connected to it across the LAN, and to manage shared resources available on the file server, such as hard disk storage and printers. Flow control - The procedures for controlling the rate of transfer of data between two points in a data network, such as between a protocol converter and a printer. This avoids data loss when a recipient device's buffer is full.
Buffers play an essential role in overall flow control in a network.
The FNC coordinates research and engineering. NetView is IBM's key implementation of the focal point. Defined in IEEE 802.3 and implemented over two fiber links, transmit and receive, this medium may be up to 500m and 1 kilometer long depending on the number of repeaters in the network. Frame - A group of bits sent over a link. CRC information - and forward error correction information.
