When it comes to network based systems and applications, more likely than not, your organization has run into performance or functional issues that are difficult to resolve. Precious operational cycles are lost as the problem is passed from one team to the next, each team doing their best to isolate components. With today's multi-tier or distributed systems, a silo approach to problem resolution may not get to the root cause of all issues in a timely manner. This is where a skilled, end-to-end network analysis approach can pinpoint problem areas, providing quantitative, detailed data on performance and functional issues.
Here is just a sampling of the types of services PBM IT provides in this area of expertise:
- Application Network Troubleshooting – We specialize in troubleshooting performance or functional issues with distributed or client-server applications. Through packet analysis, fault isolation, data gathering and validation; we can assist in identifying the root cause of complex issues that plague enterprise applications.
- Application Network Analysis – We provide analysis focused on understanding and describing the properties of an application, as it pertains to the network. Data can be used to address an issue or to assist in understanding the impact of a change or anomaly within a system. For example:
- You need to understand why this application is performing poorly or why an application is failing.
- You need to make changes to your environment and want to understand the network aspects of the current systems in order to make the right choices for the effort as well as to identify potential risks or constraints to the effort.
Network packet analysis that is application-aware is critical to solving these types of issues. Additionally, a network analysis approach must be able to factor in multi-tier and distributed applications. PBM IT has extensive experience troubleshooting and identifying complex issues. We understand Web, Application, and Database interaction with the network. In addition, we have proven solutions that address WAN impact as well as application scalability.
Example
In the following example, we have a Three Tier application. There is a Client Browser, a Web Application Server, and a Database Server. In the OPNET ACE Bound Diagram, you can see packet interchange between each tier, along with client and server processing dependencies.
