Brocade Featured White Paper: Network Packet Brokers for Next-Gen Networks
A new class of network packet brokers is emerging to meet the demands of software-centric architectures and expanded feature sets.

IEEE Spectrum has a wonderful article series on Lessons From a Decade of IT Failures. It’s not your typical series in that there are very cool interactive graphs and charts based on data collected from past project failures. They are really fun to play with and I can only imagine how much work it took to put them together.
The overall takeaway of the series is:
Even given the limitations of the data, the lessons we draw from them indicate that IT project failures and operational issues are occurring more regularly and with bigger consequences. This isn’t surprising as IT in all its various forms now permeates every aspect of global society. It is easy to forget that Facebook launched in 2004, YouTube in 2005, Apple’s iPhone in 2007, or that there has been three new versions of Microsoft Windows released since 2005. IT systems are definitely getting more complex and larger (in terms of data captured, stored and manipulated), which means not only are they increasing difficult and costly to develop, but they’re also harder to maintain.
Here are the specific lessons:
Wind River Glenn Seiler defines "open" & gives his two cents on open NFV for TEMs.
Time for another fill-in-the-blanks survey: how many vendors support NETCONF and/or REST API in their data center switches, routers, firewalls and load balancers?
Please help me complete the tables by writing a comment – and do keep in mind that it only counts if it’s documented in a public configuration guide on vendor’s web site.
Also, I’m not aware of any vendor using standard NETMOD YANG models. If someone does, please let me know.
Read more ...Great news everyone. Some of you might have seen that I created a petition to increase the node limit in VIRL. I know there have been discussions within Cisco about the node limit and surely our petition wasn’t the single thing that convinced the VIRL team but I know that they have seen it and I’m proud that we were able to make a difference!
On November 1st the node limit will be increased to 20 nodes for free! That’s right, you get 5 extra nodes for free. There will also be a license upgrade available that gets you to 30 nodes. I’m not sure of the pricing yet for the 30 node limit so I will get back when I get more information on that.
When the community comes together, great things happen! This post on Cisco VIRL will get updated as I get more information. Cisco VIRL will be a much more useful tool now to simulate the CCIE lab and large customer topologies. I tip my hat to the Cisco VIRL team for listening to the community.
The post Network Simulation – Cisco VIRL Increases Node Count appeared first on Daniels Networking Blog.
Larry Ellison & Co. are serious about IaaS
Kolla provides production-ready containers and deployment tools for operating OpenStack clouds that are scalable, fast, reliable, and upgradable, using community best practices. Kolla entered the OpenStack Big Tent during the Liberty cycle by submitting Kolla to OpenStack technical committee oversight -- enabling the Kolla project and its contributors to have access to community resources such as marketing, technical resources, bi-yearly conference space and voting rights in the OpenStack Technical Committee election.
During the creation of the Kolla mission statement, we agreed as a community not to permit the selection of technology choices in our mission statement. Still: we knew we would choose Docker as our container runtime technology, and Ansible as our orchestration system. We made these choices not only because “that’s what all the cool kids are doing’ -- but also because they solve real technical problems for our problem domain. Docker solves our image management process and Ansible solves our multi-node deployment process. We could have chosen other technologies to solve these problems, but both Docker and Ansible do something orders of magnitude better than competitors: a complete and absolute focus on simplicity coupled with a high degree of capability.
Since a fundamental factor in outcome of Continue reading
