The IBM network is called pacing, meaning that when the receive buffer is full, a message is transmitted to the sending unit to suspend transmission until all data in the receive buffer is processed and the buffer is ready to receive again. =========================================================== =============== The area of ​​the possibility of being discarded. Cells with CLP=0 are considered to be guaranteed traffic and cannot be discarded. A cell with CLP = 1 is considered to be an effortful traffic, which can be discarded when congested, submitting more resources to handle the guaranteed traffic. Maximize the specification of running IP OVer ATV . Also known as "CIA" . A non-distributed backbone.

AppleTalk----Apple Communications Corporation is a communication protocol suite designed for use in the Macintosh environment. There are currently two versions. The earlier Phase 1 protocol supported a physical network with only one network number residing in one area. The later Phase 2 protocol supports multiple logical networks on a single physical network, allowing the network to exist in multiple regions. See zone .
