TCP Acceleration solutions on the journey from QoS to 5G

QoS (Quality of Service) was first defined by ITU (International Telecommunication Union at the year 1994. QoS became a standard in Layer 3 (IP) ve Layer2 (LINK) of ISO Stack Layers, developing from that time on and internet was mainly operating on IP during that period. Starting from that time, problems started arising from the fact that IP was mainly operating on best-effort basis for media applications. In order to overcome these problems, people realised that ethernet which was used to connect to printers in offices could also be used for transport purposes. Thanks to the efforts of MEF (Metro Ethernet Forum) this proposal had become a product and QoS gained its place in ethernet. In order to make this transition, that is to make QoS an internet standard, the problems arising from using QoS in the framework of IP and Ethernet were solved at those times.

But, QoS concepts could not cope when mobile communication usage had become widespread. It was almost impossible to use QoS in transfer from one base station to another in GSM because of problems in managing “Mobile data and transaction”. That was because during this transfer from one base station to another, neither the capacity nor the loading rate of the new base station was known. This phenomenon resulted in “not providing service” decisions that had to be taken because of “outage probability”and “co-channel interference” caused by excessive loading. But today, innovative solutions which will be provided by 5G are expected to be able to cope with increased demand and to improve the service quality.

When one looks back into the history of mobile communications, 3G was mainly designed for voice communications, whereas 4G was intended to be a long-term and flexible solution (LTE-Long Term Evolution). But, the user applications and experience showed that it was not so. It seems that 4G which was started with the dream of endless lifespan and continuous improvement will be replaced by 5G in the near future. So, what can be done, without renewing the hardware intended for the voice and data traffic, in the time period required for the huge investment needed for creating the fiber infrastructure along with 5G investment? New technologies will emerge from the solution proposals which will try to solve the paradoxes resulting from requirements contradicting with each other. The widespread usage of 5G in relative to 4G will probably extend beyond 2025 and require tens of billions to hundreds of billion dollars. In the meantime, the chaotic web problems caused by the limited bandwidth can only be solved by the product “SpeedUpBOX TCP Acceleration” while solutions are sought for these paradoxes.

Today, millions of cellphone and internet users send and receive simultaneous data, voice and video increasing the overall data traffic. This day-by-day increasing data traffic, makes it critical to be able to provide an infrastructure which does not create packet loss and latency. Our “SpeedUpBOX” solution, while speeding up the TCP traffic between the end user and the senderreciever providing the service the end user needs, also speeds up the internal TCP traffic of the ISP system. The reliable and fast realization of this traffic will directly benefit the end user. Our “SpeedUpBOX” solution being placed at the output of eNodeB Retransmission of the Service Provider, will increase the traffic efficiency and the speed of the TCP data traffic independent of the eNodeB operating systems.
