Wire data analytics AND Traffic Optimization
Given the evolution of communication networks, their administration and supervision tasks usually lead the responsible team to work reactively, trying to solve application performance problems that have been reported by users. It is not easy in a distributed environment, with applications hosted in the private cloud, and others in the public cloud, to be able to identify where the problem is. Is it in any of the elements that are part of the communication chain? Is it in the SaaS provider? Is it in my communications service provider? Is it a problem at the network level, internal or in the Internet exit?
Consequently, many organizations have adopted Wire Data solutions. This consists of network probes capable of identifying all applications using DPI (deep packet inspection), measuring their performance, and providing metrics of their quality of experience. Once the behavior of the network at level 7 is understood, we should move to the next level: if we identify network issues, latencies, bottlenecks, or low quality of experience, we must be able to act and improve the network performance In the first place, it is vitally important to have an application control and management system. In order to avoid bottlenecks, it is necessary to grant different quality of service policies to different applications according to their nature. What’s more, nowadays, given the new scenario caused by the Covid-19, there is a need to ensure that all video call applications have the necessary assured bandwidth to operate in real-time. Similarly, if there is saturation in the network, it is convenient to decrease the priority of other less critical flows such as email applications, system updates, etc. and even block unwanted traffic on the network such as Thor, Netflix, etc. All these functionalities can be achieved with Viewtify QoS, the latest generation of bandwidth management products.
Secondly, part of the internet's success is due to the TCP protocol. However, in its initial design, it was not taken into account how the networks were going to be in the future. As a result, the TCP protocol is very conservative answering to discards, high latency or congestion, causing performance limitations. Until now, optimization solutions were understood to improve WAN performance and required one instance at each of the sides of the communication. This is because the approach was to tunnel the traffic in a different protocol. Therefore, this kind of implementations leads to extremely complex and expensive projects. Viewtinet, with Viewtify TCPO, provides a disruptive technology, that allows optimizing TCP flows from a single point of communication. It does not break the TCP protocol, making it work even for HTTPS. That is why in environments where all users are connected by Wi-Fi, such as hotels and universities, it is turning out to be a tremendously effective technology, optimizing up to 200% the performance of many flows.
Taking all of the above into account, Viewtinet proposes a unique solution where, from a single appliance, all these needs can be met:
- Network probe, Viewtimon, capable of identifying applications, providing network KPIs, and measuring the quality of experience. Besides, it can work as a sniffer to capture packets continuously 24x7.
- Bandwidth manager, Viewtify QoS, to grant different priorities and quality of service rules to guarantee the efficiency of critical applications.
- TCP optimization, Viewtify TCPO, capable of accelerating all TCP flows, increasing flow speed, and improving the quality of experience.
