View network traffic history data in Ossim

View historical data for network traffic in OssimEstablishing a baseline in a monitoring network segment is an important measure in network monitoring, and there is no baseline flow without a comparison criterion, which can be used to detect the traffic changes that cause the problem. By sniffing packets, conducting protocol analysis (implemented through NTOP), and providing Sflow/netflow monitoring sample data under the Ossim platform, the data is mo

instances.Open VSwitchOpen VSwitch is a production quality, multilayer Virtual Switch licensed under the Open Source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard manage ment interfaces and protocols (for example NetFlow, SFlow, SPAN, RSPAN, CLI, LACP, 802.1ag).Path MTU Discovery (PMTUD)Mechanism in IP networks to detect end-to-end MTU and adjust packet size acc

solution is as follows. Figure 3 system protection Overview Now, if the server in the Shanghai IDC center is under heavy DDoS attacks, the protection process is as follows. 1,Attack DetectionIn the event of a DDoS attack, the attack traffic monitoring device deployed inside the core network and at the exit of the IDC center sends the Netflow data collected in real time to the security management platform, after judging whether a DDoS attack has occ

How to recognize the Cisco Switch Model in one minute

connected using Ethernet Channel Technology (Fast EtherChannel, FEC or Gigabit EtherChannel, GEC), logically achieving a port rate of 16 Gbps, you can also implement port aggregation across modules. Multi-layer switching: multi-layer switching modules of the C6000 series can be used for line-rate IP, IPX, and IP-multicast routing. Good Fault Tolerance: C6000 series with redundant super engine, redundant Load Balancing power supply, redundant fan, redundant system clock, redundant uplink connect

Discussion on user behavior analysis methods of IP Networks

Internet, the demand for user behavior analysis is constantly changing. Second, users' online habits may change due to the network control and Business Development Strategies of telecom operators and information providers. Thirdly, user behavior analysis sometimes does not have a clear vision, the actual analysis requirements may be gradually improved in the data analysis and processing process. Therefore, a complete set of models is required for user behavior analysis to adapt to the dynamic a

Layer-3 Switching Technology and Its Application in VLAN subnet Planning

. When the network switches transmit data between different ports, they are also the destination MAC address based on data packets. The realization of a vswitch usually adopts a full hardware structure and is fast, but it does not have the ability to isolate broadcast data packets like a bridge. LAYER3SWITCHING is an emerging network interconnection technology that integrates the advantages of the above two technologies, also known as layer-3 switching technology. If you only consider IP, it is

New features and new features of cloud firewall

Cloud Firewall is a new concept, the first by the IT giant Cisco proposed, their approach is: upgrade their firewalls to the "cloud" firewall, to achieve dynamic prevention, active security. Cisco believes that the emergence of the cloud firewall means the emergence of the fifth generation of firewalls (the first four generations are: software firewalls, hardware firewalls, ASIC firewalls, UTM). The 4 characteristics of cloud Firewall include: Anti-Zombie network/trojan, prevent network interna
