Protocol Analyzers
Any device that captures and interprets the network traffic between two or more connected computer systems. The traffic can then be decoded so that it is possible to see what processes are occurring. By examining the flow of traffic, protocol analysers can be used to find out where problems (such as bottlenecks or the failure of a network device) are on a LAN .Advanced protocol analysers can also provide statistics on the traffic that can help to identify trends that may in future lead to further problems with the network.

Netasyst

 

Network Associates Inc

http://www.asl-netasyst.co.uk/

This analyzer captures frames, simultaneously building a database of network objects from observed traffic to detect network anomalies. Once Netasyst has isolated, analyzed, and categorized a problem it alerts you, explains the problem, and recommends corrective action.

Netasyst™ Wireless + LAN bundles provide the flexibility to monitor Wireless and LAN networks simultaneously. Netasyst bundles enable the simultaneous monitoring of both the LAN and Wireless interface to provide full visibility from the Wireless network all the way to the LAN. Full visibility ensures that you can identify problems quickly.

NetBoy Suite

 

HCL Communications

http://www.snmp.co.uk/netboy/index.htm

PacketBoy is a sophisticated protocol analyser capable of decoding a large variety of commonly used networking protocols. It provides an intuitive display of captured packets   along with their decoding. Facilities are provided to filter incoming network traffic and decode and display monitored packets. It will allow you to select either the real-time monitor or capture console from the tools menu on the PacketBoy screen. You can also choose to display both. The real-time monitor provides an accurate representation of the load on your network (as a percentage of total available bandwidth). It is displayed as the load chart on the real time monitor window. The other window you can display is the capture console (selected from the tools menu) which is central to primary functions of PacketBoy. The capture console allows you to start, pause, stop and view packet captures, as well as setting packet triggers and filters. The menu bar also provides access to these functions, as well as the ability to load and save captures.

EtherPeek NX

 

WildPackets Inc

http://www.wildpackets.com/

EtherPeek NX allows multiple, simultaneous capture sessions to be active at the same time and from different segments of the network. Multiple capture buffers can be used for a single adapter to separate different types of traffic (ie: TCP/IP into one buffer, NetWare into another). Also, in order to analyze traffic from different network segments, multiple LAN and/or WAN adapters can be used simultaneously. If RMONGrabber is employed, packet data from remote segments can also be accessed. The EtherPeek NX Peer Map is drawn as a vertically-oriented ellipse, able to grow to the size necessary to show all communicating nodes within your network. Reading the peer map is easy: the thicker the line between nodes, the greater the traffic; the bigger the dot, the more traffic through that node. The number of nodes displayed can also be limited to the busiest and/or active nodes, or to any EtherPeek NX filters that may be in use. It also provides over 100 real-time conditions tracked by the alarm system. The expert system has added the ability to set 3 conditions - Suspect, Problem, and Resolved - providing finer control over when a particular condition should be considered informational, minor, major, or severe.
