What is web-scale networking?
If you’ve heard the buzz in the networking world lately, or if you’ve been paying attention to the back-to-back launches by Cumulus Networks as of late, then you’ve probably heard the term, “web-scale networking.” But what does that actually mean?
The term web-scale networking is inspired by data center giants like Facebook and Google. The industry looked at data centers like theirs and asked, “what are they doing that we can mimic at a smaller scale?” By analyzing these organizations and the benefits they receive from their tactics, the term “web-scale” was born. Essentially, web-scale refers to the hyperscale website companies that have built private, efficient and scalable cloud environments.
Web-scale networking: a definition
Web-scale networking is simply a modern architectural approach to infrastructure. The differentiating components are taken from the key requirements that large data center operators use to build smart networks. Businesses can design cost-effective, agile networks for the modern era by adhering to these three constructs:
- Open and modular
- Intelligence in software
- Scalable and efficient
These three constructs essentially comprise web-scale networking.
While compute has advanced through leaps and bounds with the convergence to private, public and hybrid clouds, networking has notoriously lagged behind. An Continue reading

The latest ransomware threat: Doxware
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
As if ransomware wasn’t bad enough, there is a new twist called doxware. The term "doxware" is a combination of doxing — posting hacked personal information online — and ransomware. Attackers notify victims that their sensitive, confidential or personal files will be released online. If contact lists are also stolen, the perpetrators may threaten to release information to the lists or send them links to the online content.
Doxware and ransomware share some similarities. They both encrypt the victim's files, both include a demand for payment, and both attacks are highly automated. However, in a ransomware attack, files do not have to be removed from the target; encrypting the files is sufficient. A doxware attack is meaningless unless the files are uploaded to the attacker's system. Uploading all of the victim's files is unwieldy, so doxware attacks tend to be more focused, prioritizing files that include trigger words such as confidential, privileged communication, sensitive or private.
