Wired Network Performance Troubleshooting and Audit

Our Mission

Network troubleshooting is the collective measures and processes aimed at identifying, diagnose and resolve problems in computer networks. It is equally effective to optimize the network.

For over twenty years, COMCERT specializes in troubleshooting for small and large businesses and organizations. Whether you have a basic local area network (LAN), sophisticated wide area network (WAN), virtual private network (VPN), wireless network, or a hosted networking solution, our specialists are here to help.

We offer a large selection of onsite and managed network services covering the complete range of network operations.


Our Philosophy

We at COMCERT understand that anytime the network goes down or a service becomes unavailable, a business is profoundly and financially affected. We are committed in helping our customers to identify the root cause of the problem, whether it be the network, the server or the application.

We believe that our ability to offer impartial diagnose and reengineering advice is a direct result of our commitment to never sell network equipment. It allows us to work in close collaboration with our customer’s existing service partners and hardware suppliers.

Close partnerships with major players in the field of network instrumentation such as Fluke Networks and Netscout has led to a vast and up to date arsenal of test and measurement devices allowing us to identify and remediate the problem fast and accurately in both physical and virtual environments.


Wired Network Performance Troubleshooting and Audit

Our NPT service is aimed at identifying, diagnose and solving problems whenever that problem is expected to be part of the first three layers of the OSI model (cable, Ethernet, IP). It is equally effective as a network auditing service, providing the foundation for enhancing and reengineering the network.

Service Process

  • You describe any problems, recent changes, unusual events and key system components
  • We discuss the purpose and goals of the service
  • We determine what equipment we need to visualize the problem and what is required for successful installation. This usually implies providing SNMP read access to all interconnecting devices such as routers and switches
  • We start our long-term and short-term analysis under your supervision and with minimal disruption of your business
  • In some cases – especially when the problem is intermitting - you will be asked to create a journal that can lead us to proper identification of the network symptoms, relating them to user-level complaints
  • We keep you up to date on our progress and findings
  • We draft a comprehensive and customer-specific report that is presented live to your team; you can ask questions and even challenge our conclusions

Fault Domain and Report

After many years of service and hundreds of use cases, we reached the conclusion that every project is unique and requires a personalized approach.

Each troubleshooting exercise starts without prejudice.  When doing business with COMCERT, there's no such thing as a standardized approach let alone a standard report. Our reports have a reasonable length; they are intense and never boring to read. 

When auditing the network in the absence of a problem noticeable at user-level, these are just a few topics that merit our attention:

  • Structured cabling infrastructure
  • Device health, port errors and - utilization
  • Network topology and documentation
  • Configuration anomalies and vulnerabilities
  • Traffic shaping, wide area capacity planning and class of service
  • Virtual switch performance
  • Service availability
