The 5th Africa Domain Names System (DNS) Forum was successfully closed on 28 July after three days of insightful reflections on the Africa DNS Industry and the business opportunities it can provide. This forum follows on the success of previous fora that have taken place in Africa over the past few years – namely South Africa in 2013, Nigeria in 2014, Kenya in 2015, and Morocco in 2016.
The hybrid cloud sits at the core of compute and storage efforts.
Founded by Kunihiro Ishiguro and Yoshinari Yoshikawa the founders of GNU Zebra, came together to form IP Infusion back in 1999 as a commercial-grade, hardware-independent networking software company. If you’re not familiar with Zebra, you probably know it’s little brother Quagga which powers everything from Cumulus Linux to Vyatta and even my old digs.. Imagestream routers. Ishiguro and Yoshikawa took Zebra, and built ZebOS, which has been working behind the scenes in products we all use every day for years. IP Infusion’s ZebOS powers everything from F5 LTM’s and Citrix Netscaler’s to Plexxi, SK Telecom, and Huawei networking products.
Today IP Infusion is selling two variants of ZebOS to OEMs, OcNOS and VirNOS. OcNOS is a full featured network OS built specifically for White Box OEMs looking for switching, routing, MPLS, and SDN support. It can support a hybrid, centralized, or distributed network framework which provides a scalable, modular, and robust framework that can be deployed on merchant silicon. VirNOS is their NFV solution that can be used for distributed or cloud based vCPE, vPE, or vRouters in your data center.
Whitebox networking is a really exciting market that I have been looking into since the SDN craze started. Continue reading
In this post, I’m going to explain how we can use an SDN controller to provision traffic-engineered MPLS LSPs between PE nodes situated in different traffic-engineering domains.
The SDN controller that we’re going to use is NorthStar from Juniper Networks running version 3.0. For more information regarding NorthStar check here. There is also a great Day One book available: NorthStar Controller Up and Running.
Typically, in order to provision traffic-engineered MPLS LSPs between PE nodes, it is necessary for the PEs to be situated in a common TE domain. There are some exceptions to this such as inter-domain LSP or LSP stitching. However, these options are limited and do not support end-to-end traffic-engineering as the ingress PE does not have a complete traffic-engineering view. I personally haven’t seen many deployments utilising these features.
So, what’s the use case? Many service providers and network operators are using RSVP to signal traffic-engineered LSPs in order to control how traffic flows through their environments. There are many reasons for doing this, such as steering certain types of traffic via optimal paths or achieving better utilisation of network bandwidth. With many RSVP deployments, you will see RSVP used in the core of Continue reading
What is Layer 0 in the OSI layers ? Isn’t OSI (Open Systems Interconnection) seven layers? Yes it is. In the standard, seven layers have been defined. Just let’s remember the seven layers of OSI. Layer 7: The application layer. Layer 6: The presentation layer. Layer 5: The session layer. Layer 4: The […]

Nonprofit takes innovative, cost-effective approach to handle higher densities in older facilities.
People have always been quick to blame the network.
You wouldn’t believe it – after almost 22 years (yeah, it’s been that long since RFC 1883 was published), IPv6 became an Internet standard (RFC8200/STD86). No wonder some people claim IETF moves at glacial speed ;)
Speaking of IPv6, IETF and glacial speeds – there’s been a hilarious thread before Prague IETF meeting heatedly arguing whether the default WLAN SSID should be IPv6-only (+NAT64). Definitely worth reading (for the entertainment value) over a beer or two.
Late last month (wow, has it been that long already?!) I had the honor of attending Tech Field Day Extra …
