TCP Problem Finder

Thinking Inside The Box

TCP Problem Finder

TCP Problem Finder allows you to see patterns in TCP, UDP, or ICMP traffic. As serious systems programmers know, many problems in the stack, network, or devices can be found this way. TCP Problem Finder finds errors or inefficiencies in configuration or performance of TCP, UDP, socket applications, interfaces, network hardware, or routes.

You can use TCP Problem Finder to:
  • Identify congestion or network traffic errors on subnets
  • Identify TCP configuration errors
  • Identify misconfigured network devices (window size, max segment size, DNS, etc)
  • Identify routes and applications with packet fragmentation
  • Identify excessive idle or hanging connections


Our products can speed up diagnostics tremendously. When you have problems requiring protocol- and packet analysis, our products can save you time. Our Problem Finder products import a Wireshark trace into our rule-based expert system to produce recommendations and reports based on years of networking expertise.
