Low-latency Hard Real-Time Communication over Switched Ethernet

Ethernet, the most widely used commodity network, increasingly moves toward switches as implementation technology thus replacing busses. This allows to use traf£c shaping techniques to implement hard real-time distributed systems on commodity networks. However, because Ethernet switches lack build-in policing features, nodes connected by Switched Ethernet need to be cooperative. Although the th...

Towards Automatic Close Low Latency Real Time Broadcas

In this paper, we present a low latency real-time Broadcast News recognition system capable of transcribing live television newscasts with reasonable accuracy. We describe our recent modeling and efficiency improvements that yield a 22% word error rate on the Hub4e98 test set while running faster than real-time. These include the discriminative training of a feature transform and the acoustic m...

It's Time for Low Latency

The operating systems community has ignored network latency for too long. In the past, speed-of-light delays in wide area networks and unoptimized network hardware have made sub-100μs round-trip times impossible. However, in the next few years datacenters will be deployed with low-latency Ethernet. Without the burden of propagation delays in the datacenter campus and network delays in the Ether...

1 Real - Time Programming With Time - Stamped Event

Assertions on time-stamped event histories (TEHs) have been used in real-time theory for specifying, analyzing, and verifying requirements and designs, and also have been proposed for monitoring implementations. This paper investigates the direct use of TEHs for programming. We define some language and system support mechanisms, show by example the potential benefits of programming with TEHs, a...
