TCP Acceleration Part II - How it works

Aritari’s TCP acceleration is designed to mitigate the performance issues latency and packet loss that impact upon both general internet use and application performance and delivery. Importantly, it has the ability to support any public or private cloud application deployment globally.
How, then, does the technology work? Basically, by removing the inefficiencies in the TCP protocol responsible for determining the amount of bandwidth in a single user session, managing window sizes regardless of latency conditions and packet loss. In this way, performance is both optimised and consistent with the company claiming up to 20x improvement in bandwidth usage and performance. From a security perspective, Aritari replaces the need to create additional overhead in the form of an encrypted tunnel, such as when using IP Sec. In addition to removing a layer of complexity, it also removes the performance hit associated with traditional encryption technologies which, according to Steve Broadhead, director of Broadband-Testing labs, has regularly been measured at up to 50% overhead.
Broadband-Testing recently concluded a series of tests on the Aritari TCP acceleration [insert link to report here] which involved simulating generic web and website access, including dialling in specific latency and packet loss values, in order to simulate different, real-world conditions. While the Aritari technology is designed to optimise all manner of links, including those with extreme latency issues (such as satellite with 500ms+ typical), the report looked more specifically at creating some typical generic Internet environments, based around quiet, regular and peak, with latency values ranging between zero and 300ms, with packet loss similarly set between zero and 2%. Broadband-Testing ran a series of back to back tests, first without the acceleration – native Internet – and then with the Aritari technology engaged to measure the benefits offered by the Aritari technology.
As was observed during the testing, the acceleration benefits were noted equally during general browsing, as well as during more intensive usage, such as file transfers, typical of a contemporary collaborative, online work session. The first test focused on the kind of initial response times that users often find frustrating when using the Internet, whether browsing or using Internet-based applications – the test measuring response time for an Internet connection, bidirectional (send and receive) and then added increasingly challenged conditions and a broad range of simulated user environments.
While at Aritari, we conservatively claim up to 20x acceleration, Broadband-Testing recorded acceleration levels of up to 64x, noting that even these results could be significantly improved upon by testing in more challenging Internet connectivity conditions. In combination with its patented VoIP optimisation, Aritari now offers a genuinely unique offering in the world of Internet optimisation, supporting both traditional optimisation and redundancy methods, but equally designed to optimise the “new normal” world of connectivity, securely and regardless of the network type, so is completely flexible and scalable.
