Differentiating Congestion Vs. Random Loss: A Method For Improving TCP Performance Over Wireless Links

The new UC technology provides the following benefits: Accurately determines random wireless losses Provides quick and efficient error-recovery Provides high throughput and low end-to-end delay and delay variance over networks with a simple bottleneck link

Wireless internet communications

University of California scientists have developed a breakthrough method that can identify network losses as either random or congestive. In addition, this new method responds appropriately to all network losses. By identifying random losses at the TCP source, the revolutionary system eliminates the need to reduce the TCP’s transmission rate for non-congestive losses.
