Are We Seeing SD-WAN Washing?

You may have seen a tweet from me last week referencing a news story that Fortinet was now in the SD-WAN market:

It came as a shock to me because Fortinet wasn’t even on my radar as an SD-WAN vendor. I knew they were doing brisk business in the firewall and security space, but SD-WAN? What does it really mean?

SD Boxes

Fortinet’s claim to be a player in the SD-WAN space brings the number of vendors doing SD-WAN to well over 50. That’s a lot of players. But how did the come out of left field to land a deal rumored to be over a million dollars for a space that they weren’t even really playing in six months ago?

Fortinet makes edge firewalls. They make decent edge firewalls. When I used to work for a VAR we used them quite a bit. We even used their smaller units as remote appliances to allow us to connect to remote networks and do managed maintenance services. At no time during that whole engagement Continue reading

Lab makes data sharing easier so medical IoT devices can be smarter

A Cambridge, Massachusetts, research lab is addressing some of modern medicine’s most overlooked issues with cutting-edge IoT technology and an open-source approach, weaving aging devices and deeply siloed data into an accessible web of medical information.The Medical Device Interoperability Program, or MD PnP, in affiliation with Massachusetts General Hospital and Partners Healthcare, is a hub for research into making medical devices dramatically smarter by making it simpler for them to share the data they gather.[ For more on IoT see tips for securing IoT on your network, our list of the most powerful internet of things companies and learn about the industrial internet of things. | Get regularly scheduled insights by signing up for Network World newsletters. ] With more and more people being monitored by IoT devices in hospitals and monitoring themselves with Fitbits and Apple watches, there’s suddenly a lot more digital data than there was before in the world of healthcare.To read this article in full, please click here

Bounding data races in space and time – part II

Bounding data races in space and time Dolan et al., PLDI’18

Yesterday we looked at the case for memory models supporting local data-race-freedom (local DRF). In today’s post we’ll push deeper into the paper and look at a memory model which does just that.

Consider a memory store S which maps locations to values. For non-atomic locations it’s not enough just to store a single memory value at the location. Instead non-atomic locations are mapped to histories H, where a history is a finite map from timestamps to values, and timestamps are totally ordered.

Every thread has a frontier, F, which is a map from non-atomic locations to timestamps.

Intuitively, each thread’s frontier records, for each nonatomic location, the latest write known to the thread. More recent writes may have occurred, but are not guaranteed to be visible.

For atomic locations, the memory store records a pair (F,x), with a single data value x rather than a history. F is a frontier, which will be merged with the frontiers of threads that operate on the location. This is expressed in the rules READ-AT and WRITE-AT in the operational semantics below. The READ-AT rule, for example, should be Continue reading
