Introduction to GET VPN
GET VPN is a Cisco proprietary technology aimed for private WAN designs where there is a need to encrypt the traffic. This may be due to regulatory requirements or just a need to keep traffic private. GET VPN is common deployed over private WAN topologies such as MPLS VPN or VPLS.
GET VPN uses IPSec to encrypt the traffic but the main concept of GET VPN is to use group security association (SA) as opposed to the standard LAN to LAN tunnels where the SA is created in a point to point fashion.
Technologies such as DMVPN requires overlaying a secondary routing infrastructure through the tunnels while GET VPN can use the underlying routing infrastructure. Traditional point to point IPSec tunneling solutions suffer from multicast replication issues because the replication must be performed before tunnel encapsulation and encryption at the router closest to the source. The provider will see all traffic as unicasts due to the overlay which means that replication can not performed in the provider network.
In GET VPN, all group members (GMs) share a common SA which is also known as the group SA. A GM can then decrypt traffic that was encrypted Continue reading

You just finished watching a CiscoLive session from the online CiscoLive On Demand Library and now you want to run and start figuring out the alphabet soup of choices and decisions that is High Availability (HA) and Fast Convergence (FC) – NSR, NSF, GR, BFD, SSO…
Happens all the time whether it be from reading, classes, discussions with fellow engineers, or in my backyard in the Cisco Customer Proof of Concept lab (CPOC)… You take the proverbial magnifying glass and pair it up with your new found knowledge and proceed to give your network a good looking at while asking the question:
“What can be done with this network so that when a failure occurs the transition from failure to recovery happens as quickly as possible?”
So once you figure that out for your network, and implement changes, you are done. Right? My opinion? No, no, no and Continue reading
If you’ve made it this far, hopefully you’ve already completed steps similar to those outlined in my previous two posts…
If you have, we’re now ready to start installing OpenStack itself. To do this, I’ve built a set of installation scripts. All of the files are out on Github…
https://github.com/jonlangemak/openstackbuild
I suggest you pull them from there into a local directory you can work off of. There is a folder for each VM that needs to be built and each folder has a file called ‘install’. This file contains all of the steps required to build each on one of the three nodes. The remaining files are all of the configuration files that need to change in order for OpenStack to work in our build. We’ll be copying these files over to the VMs as part of the install.
A couple of notes before we start…
-The beginning of each each install file lists all of the packages that need to be installed for this to work. I suggest you start the package install on each VM at the same time as it can take some time Continue reading

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 organizations work to make big data broadly available in the form of easily consumable analytics, they should consider outsourcing functions to the cloud. By opting for a Big Data as a Service solution that handles the resource-intensive and time-intensive operational aspects of big data technologies such as Hadoop, Spark, Hive and more, enterprises can focus on the benefits of big data and less on the grunt work.
The advent of big data raises fundamental questions about how organizations can embrace its potential, bring its value to greater parts of the organization and incorporate that data with pre-existing enterprise data stores, such as enterprise data warehouses (EDWs) and data marts.
