The teaching version of Kelai s network analysis system

The transformation of Internet technology is accelerating, and the introduction and evolution of new technologies such as 5G, cloud computing, big data, Internet of Things, and artificial intelligence have made the value of data higher and higher.

Combined with nearly 20 years of technical precipitation and practical experience accumulation in the field of network traffic analysis, Kelai and CSNA Network Analysis Certification jointly launched a series of public courses in 2021.

Through the combination of theory and practice, this open course takes network traffic analysis technology as the core, through the systematic and systematic teaching of network-related knowledge, and at the same time conducts in-depth analysis and summary of typical cases such as network troubleshooting, business performance management, APT attack confrontation, zombie Trojan horse worm, etc., so that students can master network analysis technology and have the idea of solving network operation and maintenance and network security problems.

The 2021 series of Kelai open courses are completely free, and each session can be directly at station B**, and most of the lecturers are senior experts and senior lecturers in the field of network technology, with national network security experience. In the course, there are not only knowledge explanations and dry goods sharing, but also rich classroom questionnaires and ** links. I hope that those who are interested in network analysis will sign up to participate and make progress together.

Traffic analysis: Up to 42 types of traffic analysis data, which can statistically analyze the entire network, a single department, a single VLAN, a single IP and a single MAC.

Kelai network analysis system provides a comprehensive and reliable data basis for network management, which can help users troubleshoot network faults, avoid network risks, improve network performance, improve fault handling capabilities, reduce fault losses and reduce management costs, therefore, Kelai network analysis system is a necessary product in network management.

Kelai network analysis system is a network management solution that allows network managers to prescribe the right medicine in various network problems, which detects, analyzes and diagnoses all the transmitted data in the network, helps users eliminate network accidents, avoid security risks, improve network performance, and increase the value of network availability.

Managers no longer have to worry about network accidents that are difficult to solve, Kelai network analysis system can help enterprises minimize network failures and security risks, and network performance will be gradually improved. It brings to the table for network managers:

1.Quickly find and troubleshoot network faults; 2.Find network bottlenecks and improve network performance; 3.

Discover and solve various network anomaly crises to improve security; 4.Manage resources, count and record the traffic and bandwidth of each node; 5.Regulate the network, view the connections of various applications, services, hosts, and monitor network activity; 6.

Analyze various network protocols and manage the quality of network applications; Kelai network analysis system integrates the industry's leading expert analysis technology to provide accurate analysis of the current complex network, and provides the most comprehensive and in-depth data basis in network security, network performance, and network faults, which is a key product required for network management of enterprises, schools, etc.

Analytics Engine. Storage Engine.

Decoding engine. The storage performance is greatly improved, and it can support real-time collection and analysis of up to 2000M network traffic.

It supports multiple types of data storage and circulation at the same time, and supports multiple storage areas. The server is responsible for the collection, analysis, and storage of traffic on the target network. At the same time, the communication port is provided to interact with the console and the analysis center respectively, which is the core of the whole system.

Servers are divided into low-end, mid-end, mid-high-end, and high-end according to different hardware configurations, which are described as follows:

The low-end servers, including RAS1000 series and RAS2000 series, are the entry-level series of Kelai network analysis systems, aimed at small and medium-sized enterprises that egress to networks with 100M bandwidth.

The RAS3000 series of mid-range servers provide wire-rate capture of up to 1000Mbps traffic and storage capacity of up to 8TB for medium-sized enterprise networks.

The mid-to-high-end servers refer to the RAS5000 series, which provide wire-rate capture of up to 1000Mbps traffic and storage capacity up to 32TB, targeting enterprise-scale networks.

High-end servers include the RAS6000 series and RAS7000 series, which support wire-rate capture of up to 10Gbps traffic. Storage capacity up to 72TB for large-scale enterprise networks. The console provides a human-computer interface through which you can monitor and backtrack the network links on the specified server in real time, and also perform playback analysis of local packets.

The real-time monitoring of the console can display the traffic trend chart, real-time data, top network segments, top hosts, top applications, alarm logs, and matrices of the network link in real time, so as to understand the operation status of the network in a timely manner.

The backtracking analysis of the console can display the traffic situation and the statistical data of various statistical objects within a specified time period, and can filter the data according to different filter conditions, and mine and analyze the data. Through retrospective analysis, users can reproduce historical fault phenomena and reproduce fleeting problems in detail, helping users quickly find and solve network problems.

The analysis center is a standard rack-mounted hardware device, which adopts an integrated design of software and hardware, provides a unified network monitoring and network analysis management platform, and provides centralized data display by regularly collecting and statistically reporting data from servers deployed in each network link.

Through the analysis center, users can view the data communication of the entire network in real time, and realize the configuration and management of servers and network links. The analysis center integrates network fault diagnosis, network performance analysis, network protocol analysis, network communication connection analysis and other functions into a unified analysis platform to expand the scope of analysis and provide fast and efficient network management.

Kelai Network Analysis System 2010 (Portable).

Kelai Network Analysis System 2010 is a second-generation network analysis engine designed and developed by itself, which provides massive data collection and high-performance real-time diagnostic analysis, and comprehensively monitors and analyzes network data through the decoding and analysis of protocol packets. It can quickly diagnose network errors, accurately identify potential hidden dangers, determine the severity of harm in a timely manner, and provide analysis and support for network security defense. Effectively evaluate network performance, find network bottlenecks, ensure network communication quality and network operation health, and build a continuous, efficient, and secure network.

Kelai Network Analysis System 2010 is a portable, desktop-level network analysis system. It can be installed on a mobile laptop and can analyze network data instantly wherever there is a problem. Collect network packets in a variety of ways for real-time troubleshooting, or replay packet archives to achieve retrospective analysis of historical network problems.

Accurate analysis through the application analysis solution can more effectively help users solve problems found in the network, and achieve accurate positioning and efficient analysis.
