With any legacy data network the consideration for real-time applications was never really an issue since most data packet would be re-transmitted if they did not arrive via TCP. With the use of UDP to handle VoIP and Video packets the need to manage the packet integrity became a mandatory issue to ensure the that real-time applications like VoIP and video did not have packet loss, jitter or latency on any of these important packets.
By pre-assessing your legacy data network with a VoIP or video generated load across your network to measure how these new applications will perform would provide the network administrator the valuable information on the capabilities of their legacy data network to fully support real-time applications. As with any engineering task, an assessment of the conditions and network infrastructure is very typical for most deployments on new applications. Why is it that most for go the pre-assessment and just deploy and wonder why they have some many issues and specialists on site to resolve problems that could have been identified before the applications were deployed.
When you decide to deploy a new mission critical application the need to assess the performance of your network should be tablestakes in the successful deployment. To ensure that every new real-time application is handled correctly the need for pre-assessments should never be overlooked.
By pre-assessing your data networks you will ensure that all new applications have the appropriate bandwidth and packet performance to deliver the quality your end-users expect.
