Smart networks, above all others, simply have no option than to deploy DPI in order to face with amount of traffic, security concerns, or the most challenging service chain service operated and controlled by the service provider/ enterprise. Not simply traffic statistics, but Sino-Telecom’s DPI can present service intelligence with real-time, feasible actions, so as to build up visible, visible and enforceable smart network.
What Is DPI's Role in Intelligent Network Operation
DPI in networking is comparable to the eyes of smart operation of a network. Traditional monitoring technologies can provide link utilization counters, percentages and simple flow records, whereas DPI can provide application-level intelligence on each packet. This intelligence isn't merely to be found in monitoring. What applications are using the network/bandwidth? If streaming to the server: Are the streams buffering because of latency or server problems? Are there sensitive business data or viruses being sent from one stream to another via encryption? Would it be nice if latency sensitive applications were getting the priority that they deserve? DPI decodes protocols, reconstructs transactions and extracts metadata and provides answers to questions like the above. DPI is used as a data source for an intelligent network operation for analytics engines, automation systems and closed loop control. DPI is not only reacting to the facts, it is providing networks with the intelligence they need – at the time – off the application.
How DPI Supports Intelligent Network Management
In order to be intelligent when managing networks, the following three skills are required: firstly, to be able to observe what is happening in the network; secondly, to be able to determine what is not happening, and; thirdly, to take action to correct the problem. All of these capabilities are supported directly by DPI. DPI keeps a real-time map of the types of applications being used, application performance and security status of all traffic traversing the network. DPI will be able to see all the packets, unlike sampling based tools which will not see the bursts and anomalies – observations complete and accurate. DPI provides in-depth metadata to be used for machine learning models. These models are trained based on the typical traffic for an application, a subscriber group and an hour of the day, and search for any anomalies that may be traffic congestion, security issues or misconfigurations. Action is also possible with integrated policy enforcement points, provided by DPI. Smart network management revolves around the full Observe-Analyze-Act cycle, driven by Deep Packet Inspection (DPI). So if a problem occurs-a large spike in video traffic that leads to network congestion, for example-DPI spots the abnormal behavior and can trigger an automatic remediation. The network can then take a step like rate limiting or prioritizing traffic to alleviate the problem.
Simple Operation of DPI in Network Management
Modern DPI combines ease of use with sophisticated capabilities. The complexity is handled behind the scenes, not by your team. Signature updates, performance tuning, and report interpretation are automated — so your specialists can focus on higher-value tasks instead of routine maintenance. The following are DPI platforms that alleviate the usage today. For signature changes it will be sent automatically and new app recognitions will be available within a couple of hours after the publication of the application. When integrated with machine learning, classification engines can automatically classify new protocols without having to wait for signatures to be updated. Application specific views of dashboards show relevant metrics such as good quality video streaming, voice calls, time to load a web page, file transfer throughput. Alerts are contextually enabled – not only are these alerts available to alert you that you've hit a threshold, but they tell you which application they're about, and who your subscribers are. DPI can be deployed and configured in hours – not weeks – for routine operations. Continuous management allows the same visibility to be used to provide easy control: during business hours, the network manager can easily identify and prioritize video conferencing traffic with a couple of clicks; the details of identifying applications and marking traffic are left to DPI.
How DPI Optimizes Network Operation Efficiency
Having teams that spend less time finding issues and more time in solving issues would make them more efficient in the operations of the network. DPI's efficiency is due to quicker root cause analysis (RCA). If a subscriber reports to DPI that an application is not performing as desired, DPI can immediately determine the cause: network related (congestions, packets lost or high latency) or otherwise. This can save hours of troubleshooting time and decrease time to the root cause. DPI also decreases false positives. If there is a lot of traffic, but it is normal traffic, an alert may be generated by a traffic surge as a result of a popular software update or event. DPI differentiates between normal traffic and traffic that is causing problems, which helps to alleviate alert fatigue and allows operations staff to concentrate on real problems. The optimization of capacity planning is also carried out. The operator no longer needs to guess at what links to upgrade and when to expect peaks of load, or how much performance is required. Rather, they use DPI data to target specific links that are increasing and what their performance needs are. Last but not least, DPI minimizes the need for special skills. A single platform offers visibility in all applications and network layers, so you can monitor video, Web performance and security from one platform instead of having to use a separate platform for each function.
Sino-Telecom DPI Solutions for Intelligent Operation
Operators can now realize intelligent network operation with deep packet inspection (DPI) solution provided by Sino-Telecom. DPI platforms provide line rate speeds up to 100G.These DPI platforms support up to 1200 Gbps traffic processing per system, featuring native support for 400GE ports and their DPI signature files can process thousands of apps, and are constantly updated to support the latest apps and protocols. They keep up to date with application recognition by automatically updating signatures and machine learning that identifies new protocols without manual intervention. The interface can be tailored for dashboard views, alarming can be context-aware and our REST API can be integrated into your automation system. The platforms can be easily deployed Inline, Out-of-Band, or as virtual instances to scale elastically as required. Operators realize the great benefit of Sino-Telecom DPI for intelligent operation, with 240+ patents, 150+ software copyrights and deployments in more than 30 countries such as France, Indonesia, Brazil and Australia. An open architecture is included so that the platform will interoperate seamlessly with current network management systems and simple operation cuts training and allows for quicker time-to-value.
Conclusion
DPI has become a key component to intelligent operation. Only DPI can give you the real-time, application-aware visibility needed to effectively follow the observe-analyze-act loop for intelligent operation of your network. Faster root cause analysis, reduced false positives, efficient capacity planning and simplified operations are just a few examples of the benefits that the detailed granular information provides. Proactive operation is no longer an added feature for networks that want to be proactive but a prerequisite.
