Abstract
The employment of the existing protocols such as Transmission Control Protocol (TCP) cannot achieve the requirements of high-speed networks such as long term evolution advanced (LTE-A) due to the large-bandwidth and low-latency links used in this network. LTE-A network is the continuation of 3GPP-LTE (3GPP: 3rd Generation Partnership Project) and it is targeted to advanced development of the requirements of LTE in terms of throughput and coverage. Then, LTE-A is not new as a radio access technology, but it is an evolution of LTE to enhance the performance. Therefore, it is necessary to enhance the TCP variants such as improving the congestion control performance over LTE-A to make these variants fulfills the needs of the huge data which transferred over the secured links. This article offered comparative evaluation and estimation of the queue size performed by different TCP source variants over traffic model of LTE-A system using the Network Simulator 2 (NS-2).The queue size measurement proved that TCP Vegas performed better than TCP Tahoe and TCP Reno that are used in the simulation scenario. Keywords: Long Term Evolution Advanced (LTE-A), queue size, Transmission Control Protocol (TCP), Network Simulator 2 (NS-2).

(ITU) systems, represented by LTE with Release 10 and beyond to be the appraised and the candidate toward
The methodology of this research is based on using three Transmission Control Protocol (TCP) variants, Vegas, Reno, and Tahoe over a traffic model of long term evolution advanced (LTE-A) network and measuring the queue size in packets when a loss packet injected in a simulation scenario using Network Simulator 2 (NS-2) simulator
Which that serving as a base for the next-generation systems. This identification specified two main work objects, called LTE and System Architecture Evolution (SAE) that leading to the description of the Evolved Packet Core (EPC), Evolved Universal Terrestrial
Summary
(ITU) systems, represented by LTE with Release 10 and beyond to be the appraised and the candidate toward. The contributions approved by this research are providing a new comparison for the performance evaluation in queue size for some standard TCP source variants.
