TCP Algebra speeds up wireless networks and eliminates packet loss2012-10-23 09:43 by DanielaTags: TCP, networks
A new way for boosting the performance of wireless networks by up to 10 times has been discovered by a team of researchers from MIT, Caltech, Harvard, and other universities in Europe. This was achieved without increasing transmission power, adding more base stations, or using more wireless spectrum. It is expected to have huge repercussions on the performance of LTE and WiFi networks. The innovation — called coded TCP — is based on complete elimination of packet loss. In wired networks, packet loss is rare, but in wireless networks it's one of the biggest issues affecting throughput. According to Technology Review, MIT's WiFi networks generally lose 2% of packets — while on a fast train, packet loss is nearer 5%. A single dropped packet causes a spike in latency. However, the researchers' creation, is a novel way of transmitting data so that lost packets don’t result in higher latency or re-sent data. It has already been licensed by several companies. In testing, the coded TCP resulted in some dramatic improvements. MIT found that campus WiFi (2% packet loss) jumped from 1Mbps to 16Mbps. On a fast-moving train (5% packet loss), the connection speed jumped from 0.5Mbps to 13.5Mbps. Read more -here-
