Industry redesign necessary for the growth of Broadband networks

By George Mattathil – There are two fundamental network technologies:

• Circuit switching
• Packet switching

Each has its own unique advantages and limitations. Neither of them can replace the other without performance and/or service impairments.

Better (in terms of performance and cost) systems can be developed by using either or both, depending on requirements — rather than preselecting packet technology.

Packet-centric approach creates inertia with premature obsolescence of circuit infrastructure and products.

Transfer Network^tm is redesign of the access network — taking into account functionality, performance, cost, compatibility with existing infrastructure, minimizing interoperability and upgrade problems. more> StrategyGroup.net/redesign/

By Linda Musthaler – For the past five years, Network Instruments, the network and applications performance monitoring vendor, has surveyed network managers to get a sense of how emerging technologies will impact service delivery and IT operations management. The results were recently published in the Fifth Annual State of the Network Global Study.

• Video has finally gone mainstream in the enterprise, especially for videoconferencing, training, and sales and marketing.

Challenges remain:

• difficulty with allocating and monitoring bandwidth (47%)
• lack of tools to manage video performance (47%)
• lack of standardized metrics to monitor video quality: latency (76%), packet loss (69%), and jitter (60%)
