Here we provide a detailed list of some of the Best Protocol Analyzers and Packet Sniffers including the features that each of them have on offer.Packet sniffers and network analyzers all have the same basic functionality however what makes each of them unique is ease of use, how well they function and how detailed the information they provide. Ultimately the choice of which packet sniffer or analyzer to use is entirely up to you and your network environment.
2) The Solarwinds Network Bandwidth Analyzer Pack.
The solarwinds network bandwidth analyzer pack is a fully featured network monitoring and analysis tool that makes it possible to detect, diagnose, and resolve network performance issues. The tool has an intuitive web based command centre that can be used to track response time, availability, and uptime of routers, switches, and other network devices that have the SNMP feature enabled.
Network bandwidth analyzer is a useful tool when you find yourself asking question such as “IS NETWORK TRAFFIC TO BLAME FOR PERFOMANCE ISSUES?” , “WHAT IS CAUSING PACKET LOSS ON THE NETWORK?” ,”WHY IS THE NETWORK VERY SLOW?” , “WHO IS USING UP ALL THE BANDWIDTH?”. All these questions can be answered with the help of two main features which are the NETWORK PERFOMANCE MONITOR and the NETFLOW TRAFFIC ANALYZER.
The NETWORK PERFOMANCE MONITOR provides detailed fault monitoring and perfomance management which helps with quick detection network issues thereby reducing network outages. The NETFLOW TRAFFIC ANALYZER provides bandwidth usage information by applications, protocols and IP addresses thereby allowing you to view both IPv4 and IPv6 flow records.
