OpenFlow Supports IPv6 Flows
Software Defined Networking systems are gaining IPv6 capabilities
Promise Theory
The way we have created IT systems over the years has been very linear with each individual component being statically configured. If a human makes an error in any one of the many configurations, then the whole system breaks down. ...
Software Containers: Used More Frequently than Most Realize
Whether you have considered trying to secure an application by putting it into a “sandbox” or wondered how a Software as a Service (SaaS) provider keeps your application and data isolated from other customers, you have been...
ARIN Enters Phase 4 of IPv4 Exhaustion
After IANA allocated the final IPv4 addresses to the five Regional Internet Registries (RIRs) on February 3, 2011, the RIRs have been running out of IPv4 addresses over the past three years. APNIC ran out on April 15, 2011; RIPE NCC...
Windows XP: Goodbye and Good Riddance
There has been much written recently about the end of support for Windows XP on April 8, 2014. There are concerns about security vulnerabilities that will be used after Microsoft stops patching the operating system. However, if...
Not your Father’s Flow Export Protocol (Part 2)
In the previous article we covered how NetFlow, IPFIX and the variety of other flow export protocols can be used to give us some application traffic visibility. However, nothing gives as much detail as raw packet decode. A new...
Your Father’s Flow Export Protocol (Part 1)
You may be familiar with NetFlow, IPFIX and other similar protocols like J-Flow and sFlow. These protocols provide useful insight into traffic mix and communities of interest. However, these protocols do not contain the...
The erosion of IT's middle class
As new technologies continue to emerge in the network, the need for highly skilled IT administration resources will grow just as well.However, the advent of Software Defined Networking (SDN), cloud systems, and orchestration software...
Clos Networks: What's Old Is New Again
Clos networks were first created in the mid-1950s as a method to switch telephone calls. Clos networks evolved into crossbar topologies and eventually into chassis-based Ethernet switches using a crossbar switching fabric. Now Clos...
Using SDN to Create a Packet Monitoring System
Because of the limitations of SPAN/monitor ports on switches, organizations have turned to using taps and packet monitoring switches. These solutions can be expensive which has lead companies to look for alternatives. Establishing...
gogoNET LIVE 4! IPv6 Conference Recap
There have been many IPv6-related conferences, seminars, and events over the past decade. These events have aimed to educate the attendees about IPv6 and the potential of the maturing Internet protocol. This year’s gogoNET IPv6...
Dual-Protocol Routing with Raspberry Pi
Network Engineers are always looking for new ways to gain some low-cost network testing capabilities. Few companies sufficiently fund networking labs for their networking teams to learn on prior to deployment. Many have use Cisco...
