We present the design, implementation, and evaluation of B4, a private WAN connecting Google’s data centers across the planet. B4 has a number of unique characteristics: i) massive bandwidth requirements deployed to a modest number of sites, ii) elastic traffic demand that seeks to maximize average bandwidth, and iii) full control over the edge servers and network, which enables rate limiting a...

A Runge–Kutta method takes small time steps, to approximate the solution to an initial value problem. How accurate is this approximation? If the error is asymptotically proportional to hp, where h is the stepsize, the Runge–Kutta method is said to have “order” p. To find p, write the exact solution, after a single time-step, as a Taylor series, and compare with the Taylor series for the approxi...

Editorial: Structured abstracts.

From Volume 45 (1992) this Journal, in common with a growing number of others, will require authors to submit structured abstracts. The decision to follow the example of the Annals ofInternal Medicine, the New England Journal of Medicine, and our own mother publication, the British Medical Journal, has been taken because we subscribe to the belief that a simple but rigid template for abstracts ...

For the purposes of this trial, German was picked as the native language. The Editors and Publishers have over the years observed that nuances, which sometimes are very important, can be lost or obscured if the author of a ...
