- 32. Challenges – Data Network Slow Applications due to congestion Video broadcast or conferencing may have bad picture quality or appear jerky Voice sessions may have bad voice quality or periods of silence Critical transactions may take too long (too many seconds) Bulk transfers take too long (too many hours) Poor performance of real time applications which are sensitive to delay, jitter and packet loss. Customer using voice, video, and data application traffic demand varying service requirements. Business Critical Data and Non Business Data treated with same priority at service provider network. No priority for Voice or video traffic. How to meet these Challenges ??

Editor's Notes
- #19: What happened in Mumbai recently on 26/7 is critically similar to 9/11 in New York whereby the business had come to a stand-still. Many enterprises were greatly affected which also lead to complete destruction of business. This has given rise to the facts that emergencies have no boundaries, disasters are unavoidable and the need to establish Disaster Recovery Solution. This is of prime importance for enterprise customers who are dependent on data communication for business requirements. All this has forced all of us to do some rethinking.
