Data Transmission Performance Enhancement in Multi-gigabit Wide Area Networks

Over the past few years amount of produced data and WAN users experienced rapid growth, e.g. according to IBM Cloud Marketing research amount of Internet Users was grown from 2.4 billion in 2014 to 4.4 billion by 2019. Over 90% of worldwide data was generated since 2016 with the every-day replenishment of 2.5 quintillion bytes. Consequently, the demand for technologies capable of handling such amounts of traffic increases as well. At the same time, the requirements for quality, provided by those technologies changed. Partially due to changes in types of Internet traffic, for example, a larger part of modern networks is filled with media traffic, some new technologies like IoT require low-latency transmission. Another part of the issue is efficiency as with the increase in data rates, overall losses from inefficient architecture increase as well, which may lead to financial losses. While these issues could be solved with specialized hardware, such an approach is less flexible and requires massive financial investments. Thus, many service providers want a solution that would utilize a provider’s existing hardware infrastructure. This article presents an overview of software solutions developed for handling these issues without significant changes in existing architecture. The complex of solutions aims at different parts of the general problem and consists of algorithms that handle network congestion, acceleration of packet processing, efficient transport protocol, methods of traffic distribution and network analysis.
