7.1 Frame synchronization: The beginning and end of each frame must be recognizable.
7.2 The function accomplished by a receiving entity to limit the amount or rate of data that is sent by a transmitting entity.
7.3 A flow control protocol in which the sender communicates a block of data and then awaits an acknowledgment before transmitting the next block.

• The buffer size of the receiver may be limited.
• On a shared medium, such as a LAN, it is usually sensible not to permit one station to occupy the medium for an extended period, thus causing long delays at the disparate sending stations.
7.5 A method of flow control in which a conveyance station may send numbered packets within a window of numbers.

(3) When traffic becomes heavy on a circuit-switching network, some calls are jammed; that is, the network refuses to accept additional connection requests until the load on the network diminishes.
9.5 In the datagram approach, each packet is treated independently, with no reference to packets that have been out before. In the virtual circuit method, a preplanned path is established before any packets are sent. Once the path is established, all the packets between a pair of communicating parties follow this same route through the network.
9.6 Packages are moved to several community segments simply by hubs located in different factors through the net. Routers are normally specific computers in which forwards boxes throughout the ideal paths, because based on this routing recursive rule being used for the system, towards areas shown by destination IP deals with from the box headers. Throughout transport in one sponsor completely to another, boxes might be routed from ordering in addition to all over a choice of paths to get at the desired
