Network resource planning

In a 2006 Reuters interview, John Roese, CTO of Nortel, pointed out that YouTube almost destroyed the Internet,[2] and in a keynote speech at Cisco’s C-Scape analyst conference in December 2006, John Chambers, CEO of Cisco Networks said, “Things like YouTube are just the baby steps of the impact video will have on networks.” Since every video transmission requires roughly 150 times the bandwidth of a voice transmission, it is estimated that a one percent adoption of the Verizon Wireless V CAST service required a 400 percent increase in Verizon’s corresponding network capacity.

The bandwidth-intense nature of next generation services has required traditional network planning to evolve.

The dramatic swings in bandwidth demand that slight variances in subscription rates bring to bear on networks carrying services such as video can no longer be adequately planned for with these traditional methods.

Furthermore, the importance of coordinating infrastructure investment activities across organizations is addressed to ensure that network capacity is provided when and where it is needed, and that human and operational support system resources are appropriately included in the planning process.

The fact that IP can drop or delay packets during overload conditions introduces new complexity to the system.

Interactive services such as voice, two-way video, and gaming are particularly susceptible to the resultant digital jitter and delay.
