Window Sliding Protocol

KeyPoints releated to the Window Sliding Protocol

-Piggybacking (security), when an authorized person allows (intentionally or unintentionally) others to pass through a secure door.

-Piggybacking, a practice in which a person with bad credit uses the seasoned trade line of credit of someone else.

-Piggybacking (data transmission), a bi-directional data transmission technique in network layer, sending data along with ACK called Piggybacking

-One bit sliding window protocol is also called Stop-And-Wait protocol. In this protocol, the sender sends out one frame, waits for acknowledgment before sending next frame

-The transport layer provides convenient services such as connection-oriented data stream support, reliability, flow control, and multiplexing..

-An acknowledgement (ACK) is a packet sent by one host in response to a packet it has received.

-A timeout is a signal that an ACK to a packet that was sent has not yet been received within a specified timeframe

-Propagation delay is defined as the delay between transmission and receipt of packets between hosts

-First role is to enable reliable delivery of packets

-Second role is to enable in order delivery of packets

-Third role is to enable flow control

-a pipeline is a set of data processing elements connected in series, so that the output of one element is the input of the next one
