About the custom-built approach becomes even less cost effective


In recent years, building, maintaining, and evolving proprietary network systems for telecom-grade applications that are highly available and "always on" have become increasingly prohibitive from the perspective of cost, risk management, time to revenue, and so on. The custom-built approach becomes even less cost effective as Communications Service Providers (CSPs) move toward offering cloud-based services, where they have to compete with non-traditional providers that offer such services on networks built using Commercial Off-The-Shelf (COTS) building blocks.

A change in market dynamics is causing a fundamental paradigm shift in industry's
thinking: Instead of continuing to invest precious Research and Development (R&D) resources and dollars to build expensive, special-purpose proprietary systems with the hope that they will never fail, industry leaders are now assuming that there will be hardware and software failures and thus designing systems and applications that continue to provide end-user service in the presence of such failures. State-of-the-art software and related standards have made significant advances in recent years to support sophisticated schemes and quick implementation of highly available applications and services that can run on relatively inexpensive COTS hardware systems.

Plug-and-play, it's gaming!

Industrial computer, Panel PC, networking appliance











Today HomePlug devices gaming account for more than 90 percent of the world’s broadband-speed power line communications market. The HomePlug standards family includes HomePlug AV for broadband applications such as HD video streams, HomePlug GP for smart grid applications, and soon HomePlug AV2, the next-generation Gigabit-class broadband standard – all fully interoperable with each other and the IEEE 1901 power line standard.
Regarding HDTV support, HomePlug AV enables a broadband-strength network gaming connection via electrical wiring for high-demand applications such as gaming  movies or online gaming. Since the introduction of the HomePlug AV standard back in 2006, its purpose has been to provide high-quality, multistream, entertainment-oriented networking over existing AC wiring within the home. HomePlug AV employs advanced PHY and Medium Access Control (MAC) technologies that provide a 200 Mbps class power line network for video, audio, and data.
