Network Consultancy.


 



Using state of the art network test equipment and software we can drill down and analyze all the network parameters to establish the root cause of any problem.
When an end user complains that an application is performing badly we can determine .

 

• Whether it is a network or server issue
• Whether it really is performing badly/ worse than normal
• Who is affected single or multiple users
• Where in the network the problem exists
• Whether other applications or traffic types are responsible
• Is the other traffic relevant or desirable
• What is running over the network
• What other requests are being issued to the server
• How much delay is there on the workstation side of the network
• How much delay is there on the server side of the network
• How much delay comes from the application
 

Our analysis systems simply plug into your network and non-intrusively monitors all the traffic passing it , including requests and responses to business applications.
By time stamping each data packet we can measure the response times and latency in each transaction and the equipment involved so all diagnostic and management information can be displayed in any form required ie
 

• Server (application response time)
• Client Network Response Time ( Originator Side Network Response Time)
• Server Side Network Response Time for each application ( Destination Network Response Time)
 

Network Environment Emulation

 

If you really need to know any of the following

 

• How will my applications perform when placed in a real network?
• Will increased bandwidth really increase performance?
• How will the application perform over long distance in a WAN?
• Can I reduce bandwidth without affecting performance?
• How robust is the application to packet loss , damage or reordering?
• Is it possible to simulate all the above without the cost of creating a “real” network?
 

Yes ! using the Environment Emulator we can emulate the conditions likely to be encountered in a live application rollout reducing the potential for costly failure. The Environment Emulator is a network in a box which can be configured to emulate any parameter you will meet in the “real” world including multiple physical interface emulation with the following configurable parameters.

 

• Bandwidth (bits per second)
• Bandwidth Allocation (packet shaping)
• Delay ( latency through the emulation system)
• Queue Length ( buffer size if data cannot be passed in time packets will be dropped as they would in the real world)
• Intercepted Dropped ( selected percentage and actual number of packets that will be dropped)
• Intercepted Eroded ( percentage and actual number of packers that will be eroded)
• Packet Order ( packets can be transported in the order they were sent or the order can be jumbled)
• Quality ( selected traffic can be prioritized for preferential delivery)
 

Using the configurable interfaces on the Environment Emulator will enable you to

 

• Create a profile of current network characteristics and performance in a single unit
• Establish a benchmark model to test and verify against
• Test over the emulated network from an off-line environment
• Identify potential disruptions to application performance by emulating a decreasing quality of connection
• Fine tune application and network requirements before implementation
• Test using prioritized traffic
 

I T is so critical to the management and profitability of business today that it can no longer be a suck it and see or slap it together and hope it works process. Business processes are becoming more mission critical and vital to profitability so you must be sure they will work and your network is adequate to support them and has the flexibility to expand with your business.
