3483 results about "Transmission delay" patented technology

In a network based on packet switching, transmission delay (or store-and-forward delay, also known as packetization delay) is the amount of time required to push all the packet's bits into the wire. In other words, this is the delay caused by the data-rate of the link. Transmission delay is a function of the packet's length and has nothing to do with the distance between the two nodes. This delay is proportional to the packet's length in bits, It is given by the following formula: DT=N/R seconds where DT is the transmission delay in seconds N is the number of bits, and R is the rate of transmission (say in bits per second) Most packet switched networks use store-and-forward transmission at the input of the link.
