Hardware life cycle approaches to save money, ensure network reliability

High-quality, reliable network hardware and data center cabling are requirements for a high-performing technology infrastructure and for a successful IT team that helps drive more business. It’s the life cycle for your network.However, in these days of shrinking budgets and rising demands, CIOs, IT professionals, and buyers are being pressured to do more while reducing costs. How can this be done?Having the right approach when it comes to network hardware and data center cabling is a powerful way to enable your IT organization to do a lot more while optimizing your budget. [ Read also: How to plan a software-defined data-center network ] The IT value within the life cycle There are many nuances to a hardware investment that some organizations don’t take into account. The opportunity to reduce capital expenditure (CAPEX) spends exists, but it requires incorporating pre-owned hardware into the equation.To read this article in full, please click here

From Imagination to Action: In Latin America, Building the Internet That Women Want

In 1843, Ada Lovelace published “Sketch of the analytical engine invented by Charles Babbage” in the book Scientific Memoirs. But because of her “condition” as a woman she, like many women who were pioneers in their time, was forgotten by history. Women could not access education or the sciences and, for that reason, history forgot them, just as we forgot that many women were mothers of the Internet.

“History drove us out of the digital industry, we stopped being important and a male industry was created.”
– Kemly Camacho, Sula Batsú

Every day many people ask us, where are the women? Why don’t they participate? I tell them to look at the immense number of initiatives that women are doing in Latin America and the Caribbean.

With the cold of Buenos Aires, between its tall buildings and its warm people, our friends at the Tierra Violeta Cultural Center received us after four months of planning the FemHackParty LAC. In December 2016, at the Internet Governance Forum that took place in Guadalajara, Mexico, we organized with a group of women the first FemHackParty, within the framework of 16 days of activism against violence against women. We had the chance to learn Continue reading

How to pin a pile of addresses onto a Google map

Turning a list of names, addresses and related information into a Google map is a lot easier than you might think. The effort required depends, as you might imagine, on the information that you starting with. But if the format is fairly consistent, it’s relatively easy to massage the information into a form that can be uploaded into a format that works.First, what you can expect Once you’ve loaded a list of names and addresses into a Google map, you will be able view the location of each person and set up your map such that clicking on any of the map markers displays the information collected for that address.To read this article in full, please click here

Last Month In Internet Intelligence: August 2018

During August 2018, the Oracle Internet Intelligence Map surfaced Internet disruptions around the world due to familiar causes including nationwide exams, elections, maintenance, and power outages. A more targeted disruption due to a DDoS attack was also evident, as were a number of issues that may have been related to submarine cable connectivity. In addition, in a bit of good news, the Internet Intelligence Map also provided evidence of two nationwide trials of mobile Internet services in Cuba.

Cuba

On August 15, the Oracle Internet Intelligence Twitter account highlighted that a surge in DNS queries observed the prior day was related to a nationwide test of mobile Internet service, marking the first time that Internet services were available nationwide in Cuba’s history. The figure below shows two marked peaks in DNS query rates from resolvers located in Cuba during the second half of the day (GMT) on the 14th. Paul Calvano, a Web performance architect at Akamai, also observed a roughly 25% increase in their HTTP traffic to Cuba during the trial period.

This testing was reported by ETECSA (the Cuban state telecommunications company) in a Facebook post in which they noted:

The Telecommunications company of Cuba S.A. Continue reading

Valley-Free Routing

Reading academic articles about Internet-wide routing challenges you might stumble upon valley-free routing – a pretty important concept with applications in WAN and data center routing design.

If you’re interested in the academic discussions, you’ll find a pretty exhaustive list of papers on this topic in the Informative References section of RFC 7908; here’s the over-simplified version.

BiB 053: Mode.net’s Cloud Private Network For Your SD-WAN

Mode briefed Ethan Banks about their cloud private network. Whoa! Thought Mode was an SD-WAN company? Not quite. Mode partners with several SD-WAN platforms so that it's easy to stand up a tunnel from your SD-WAN forwarders to Mode's private network. That makes Mode a network alternative to private MPLS that integrates with your SD-WAN fabric.

IDG Contributor Network: What’s wrong with Cisco running SD-WAN on your routers?

Cisco’s announcement earlier this month that it will add the Viptela SD-WAN technology to the IOS XE software running the ISR/ASR routers will be a mixed blessing for enterprises.On the one hand, it brings SD-WAN migration closer to Cisco customers. On the other hand, two preliminary indicators —  one-on-one conversations and Cisco’s refusal to participate in an SD-WAN test —  suggest enterprises should expect reduced throughput if they enable the SD-WAN capabilities on their routers.Cisco’s easy migration to SD-WAN By including the SD-WAN code with IOS XE, Cisco will provide a migration path for the more than one million ISR/ASR edge routers in the field. There’s been a lot of conversation as to whether or not SD-WAN is going to kill the router performance. Delivering SD-WAN code on the ISRs is Cisco’s answer: routers are here to stay but they’ll morph into SD-WAN appliances.To read this article in full, please click here
