TCP acc Part 1

​Data and application optimisation is nowadays a given – or at least it should be – for any form of remote connectivity.
Why would you not accelerate traffic and reduce bandwidth consumption if you can? However, much of the development in optimisation in recent years has focused on specific application acceleration; the issue here is that the end-to-end nature of the optimisation means that endpoints need to be able to see and decode that data being transferred. For this reason, each protocol - for example, http, ftp and others – has specific support developed for it. In a world where, ever increasingly, the focus is on secure, encrypted connections, this level of visibility often no longer applies. If it’s encrypted, you can’t see what it is – simple as.
The popular data deduplication relies on data not being random, so that duplicate segments can be compressed into shorter references rather than being sent multiple times, While the Aritari technology can do this if necessary, given that most data is encrypted and therefore appears to be random as far as the network is concerned, this technique is not effective in a modern scenario. The Aritari solution can be deployed on virtual machines, so for example you could spin up a “head end” in Azure and use unencrypted connections within a tunnel, using Aritari to encrypt data as it’s sent over the public network - this way, data deduplication can be used successfully and still securely.
But generic TCP traffic, not least for Internet browsing, is still the primary data traffic for optimisation. However, this requires a different approach in the modern, secure connected world. Aritari has the solution in that our TCP Acceleration (TCPA) will accelerate all such traffic significantly, whether encrypted or not. 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. It has the ability to support any public or private cloud application deployment globally so, regardless of whether the approach is hybrid or pure-cloud, the solution is in place. Moreover, the increase in remote users globally means many will be using less than perfect Internet connectivity. The Aritari technology is designed to be more effective the more challenging the connections, so as common problems such as latency and packet loss increase, so too does the effectiveness of the Aritari solution.
So, viewed from an Aritari perspective, generic TCP acceleration applies to all TCP traffic – that being most network-based traffic - without needing to be aware of the application or information contained within it. As noted, TCPA will accelerate all such traffic significantly, whether encrypted or not, but especially in certain, common circumstances, such as:

• Where many small items are transferred, common to almost all web traffic.
• Any packet loss is present, as is the case at some point in almost all Internet connections and especially so in the “new normal” with bandwidth contention being more prevalent as traffic becomes ever-increasing.
• When multiple, mixed traffic transfers are taking place simultaneously, again as is the case on most Internet links.
• As latency increases - Aritari makes a noticeable difference even at lower latencies, but the positive effect increases as latency itself increases.
• Where there are what we might call “long fat pipes” – i.e. when bandwidth times latency is a high value. Examples of this scenario are fast international connections (whether private circuit or Internet-based) and bonded connections, with multiple, aggregated links.

Web browsing speed is further increased because of the fact that the client believes it connects to the server much more quickly than it would otherwise (and so can send the initial request far more quickly). From a user perspective this happens in the order of a few milliseconds, rather than experiencing the entire latency of the link to the server.
So, 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, being completely flexible and scalable.
