IEEE spec aims to ease mobile congestion
The P2200 specification is a protocol for stream management in client devices supported and to some extent managed by a new ad hoc industry group called the High Quality Mobile Experience (HQME) Steering Committee.
The P2200 spec will provide a "mechanism to queue content for later delivery rather than initiate the stream immediately, and to time-shift streams so they are not as dependent on the network conditions," said David Koren, who will chair the IEEE working group, speaking in an IEEE press release.
“P2200 will intelligently route and replicate content over heterogeneous networks to mobile devices with local storage, without disrupting content providers’ direct relationships with end users,” Koren said.
The proposed standard will view memory on a mobile device as the last node on the network. As such it will call for compliant applications to download content when the mobile device is connected to AC power and Wi-Fi rather than over cellular nets during peak hours. It may also facilitate preemptively downloading content to the device’s local storage to avoid mobile network congestion during peak hours.
According to figures from Cisco Systems, overall mobile data traffic is expected to grow at a 92 percent compound rate from 2010-2015. At that rate mobile users will access 6.3 exabytes per month by 2015, a 26-fold increase over 2010.
“This issue affects all members of the mobile ecosystem,” said Flint Pulskamp, research director for wireless and wired communications semiconductors at International Data Corp. “The proposed solution requires an industry-wide approach so that it is both effective and sustainable,” he said, speaking in the IEEE release.
The IEEE committee includes representatives from AT&T, Broadcom, Google, Nokia, Orange, SanDisk and Texas Instruments. According to an IEEE press release, the HQME Steering Committee "will oversee the coordination of the working group and the development of business models that implement the standard."
An IEEE spokeswoman said the HQME group would not directly manage the P2200 effort in any way, but it does plan to oversee in an informal way implementations of the technology.
Members of the HQME Steering Committee include Orange, SanDisk, SoftBank Mobile, and Sony Pictures Entertainment.
“Solving the problem takes an industry-wide effort, and that’s the purpose behind the HQME steering committee,” said Robert Khedouri, general manager of software and solutions at SanDisk, in an IEEE release. “The HQME initiative will take some time, but progress has already been made by putting our collective heads together to propose a standardized solution aimed at increasing customer satisfaction," he added.
