Going the last meter.
Going the last meter.
Before the ATOMIC LAN, the bottleneck was in the LAN. Host interfaces, file servers, and gateways could support a significant portion of the available LAN bandwidth (line widths are proportional to BW).
The presumed solution is to install a faster LAN, e.g., Fast-Ethernet, FDDI, ATM, or the ATOMIC LAN (again, line widths are proportional to BW):
The problem is that LAN bandwidth gets you only so far. Interfaces have limitations, due to driver software and hardware design. OS interactions further limit available bandwidth at the application layer.
ATOMIC-2 is aimed at addressing these remaining limitations. In telephony, it is well-recognized that the majority of costs and complexity lie in the local loop, the last mile to the customer's phone. In the ATOMIC-2 project, we are addressing the equivalent networking concept...
