Log Analysis using Artificial Intelligence/Machine Learning [AI/ML] for Broadband   Whenever you hear about “Log analysis”, we picture a developer, going through 1000s of lines of logs to figure out a problem. Does it always have to be like this? Our topic of discussion is what can Artificial Intelligence/Machine Learning [AI/ML]do to help us in Log analysis. Need for Automated Log Analysis   In large-scale systems, the seemingly obvious way of log analysis is not so scalable. A  broadband network managed by an operator like Comcast, having 100s of Wi-Fi Access Points and Route ..read more

Cloud, cutting-edge web technologies and open source movement are helping us build, deploy and scale innovative and intuitive applications at a rate never seen before. However, the Networking world faces unique constraints, as a part of the applications have remained on devices/servers/gateways/Embedded Devices (On-Premises), while the core is still being driven from Cloud. In this blog, I will discuss how to package the On-Premises software application. In the blogs to follow, we will be touching on cloud applications and how to automate that. On-Premises software applications are platform s ..read more

As soon as someone mentions “Log analysis”, we picture a developer, going through 1000s of lines of logs to figure out a problem. Does it always have to be like this? Our topic of discussion is what can AI/ML do to help us in Log analysis. Need for Automated Log Analysis In large-scale systems, the seemingly obvious way of log analysis is not so scalable. Imagine a broadband network managed by an operator like Comcast, having 100s of WiFi Access Points and Routers/Switches and 4G/5G small cells, from multiple equipment providers, say Commscope, Aruba or CISCO. If we are collecting logs at mul ..read more

Introduction There is a constant threat to your network from various actors in the big bad networking world. These actors use various techniques to steal information (malware) or prevent your network from working normally (attacks). It is imperative that Network administrators take actions to protect our network from them proactively (ex: antivirus, firewall).  Wireless networks in unlicensed bands like Wi-Fi are more vulnerable because of their “open” or accessible “to all” nature, unlike a wired network in a building or an underground duct, where we can protect it by limiting the access ..read more

Introduction to WiCheck In the earlier post, we have discussed packet editors and how you can create your own packet sequence. In this article, we will explain in detail how to inject probe packets with WiCheck to test how well your AP can handle pre-defined packets – custom, malformed, malicious or normal from a single client or from 100s of clients at a time SWAT WiCheck is a modular and programmable Wi-Fi multi client simulator that can scale to 100s of 802.11 a/b/g/n/ac/ax clients. All the clients act exactly like real users with up to 8 spatial streams in the Wi-Fi6 variant. It runs real ..read more

What is Packet Injection? Every network equipment maker would want to test different features and also ensure that the equipment is not susceptible to (1) malicious attacks, (2) malfunctioning devices. Packet injection is one of the ways to replay these message sequences from the client side and check the stability and security of the device under test. For example, you can send directed probe requests from the clients so as to test how well an AP can handle probes from several clients or a single rogue client. Open nature of wireless networks makes it easier for an attacker who is within th ..read more
