Ware Wan Lan Bandwidth Traffic Monitoring
A Survey of Network Traffic Monitoring and Analysis Tools A Survey of Network Traffic Monitoring and Analysis Tools Chakchai So-In, Abstract: From hundreds to thousands of computers, hubs to switched networks, and Ethernet to either ATM or 10Gbps Ethernet, administrators need more sophisticated network traffic monitoring and analysis tools in order to deal with the increase. These tools are needed, not only to fix network problems on time, but also to prevent network failure, to detect inside and outside threats, and make good decisions for network planning. This paper surveys all possible network traffic monitoring and analysis tools in non-profit and commercial areas.
Network traffic monitoring and accounting software solution that supports 10 Gbps Packet Sniffing,Port Mirroring,Network TAP,NetFlow,sFlow,jFlow and IPFIX. End-to-End Network Monitoring Software for LAN. Critical LAN and WAN infrastructure with traffic analysis. Are hogging bandwidth and which apps are. How to monitor WAN traffic? There are several software tools that can do what you want. Is there a way to monitor network throughput under Windows XP?
The tools are categorized in three categories based on data acquisition methods: network traffic flow from NetFlow-like network devices and SNMP, and local traffic flow by packet sniffer. The popular tools for each category and their main features and operating system compatibilities are discussed. The feature comparisons on each category are also made.

Introduction Network monitoring and measurement have become more and more important in a modern complicated network. In the past, administrators might only monitor a few network devices or less than a hundred computers. The network bandwidth may be just 10 or 100 Mbps (Megabit per second); however, now administrators have to deal with not only higher speed wired network (more than 10 Gbps (Gigabit per sec) and ATM (Asynchronous Transfer Mode) network) but also wireless networks.
They need more sophisticated network traffic monitoring and analysis tools in order to maintain the network system stability and availability such as to fix network problems on time or to avoid network failure, to ensure the network security strength, and to make good decisions for network planning. When a network failure occurs, monitoring agents have to detect, isolate, and correct malfunctions in the network and possibly recover the failure.
Commonly, the agents should warn the administrators to fix the problems within a minute. With the stable network, the administrators' jobs remain to monitor constantly if there is a threat from either inside or outside network. Moreover, they have to regularly check the network performance if the network devices are overloaded. Before a failure due to the overload, information about network usage can be used to make a network plan for short-term and long-term future improvement There are various kinds of tools dealing with the network monitoring and analysis, such as tools used by Simple Network Management Protocol (SNMP), Windows Management Instrumentation (WMI), Sniffing, and Network flow monitoring and analysis. Given the data packet and network traffic flow information, administrators can understand network behavior, such as application and network usage, utilization of network resources, and network anomalies and security vulnerabilities. In this paper, we survey all possible network traffic monitoring and analysis tools in both public and commercial areas.

In section 2, we classified the tools in three categories based on how to retrieve the network flow information: network traffic flow information from network devices (NetFlow-like in section 2.1 and SNMP in section 2. Lounge Lizard Ep 4 Serial Number. 2) and from local traffic network (by packet sniffer in section 2.3). The popular tools for each category with main features and operating system compatibilities are given.
