lost packet

lost packet

A packet of data that never reaches its destination. For example, if the network becomes congested and the traffic exceeds the momentary holding capacity (buffer space) of the router, packets will be lost.

This is heightened because of the huge requests from subscribers coupled with the variation of the unicast packet rate of transmission and ability to the recover lost packet. Chase [5] summarizes that IP multicast is used as a countermeasure because it provides huge bandwidth efficiency over the unicast delivery.
Different lost packet from different receiver are merged to retrieve the lost data packets in one transmission by a multiple receiver [9].
Packet loss ratio is described as the ratio of lost packet and the total packet per unit of time.
TCP fast re-transmission [7] mechanism reduces the time that a sender waits before re-transmitting a lost packet. Thus when receiver receive abnormal data or out of order data then it immediately sends the duplicate ACK to the sender and if sender receives three ACK that means packet loss, then the sender immediately re-transmit the lost segment to the receiver without any wait.
In this article we use the terms lost packet or packet error as general terms for all situations when the received packet has any bit errors, including complete transmission channel failure.
Miguel Cristobal, CEO of SAPEC, Our engineers were very impressed with it as, over a period of a month, every lost packet was recovered and this was over a standard 6Mbps ADSL connection with no Quality of Service (QoS) in place.
Since packet error rate is the same, compared to shorter packet length, the lost packet number will be less.
If the protocol like RED [15] which is based on the TCP protocol is used for QoS, each packet needs to be confirmed and every lost packet needs to be retransmitted.
(ii) There are periods without any lost packet and periods with many losses (bursts).
