Thinking of implementing SDN in your MPLS WAN ? without a forklift ? Look no further ! as BGP-LS ( BGP-Link State) and PCE ( Path computation Element) give a right combination. In this Blog, I talk about an evolutionary ( not the revolutionary approach) to SDN in WAN. SDN-based MPLS network, running PCE and […]
The emerging Docker containers have potential to revolutionalize NFV. After all, they are lightweight compared to virtual machines; they need less overhead and resources; and, they can provide application isolation running in the same operating system, they live in. That means, if a Virtual Network function (VNF) in NFV can run in a Docker container […]
If you are a traditional optical/DWDM vendor, then be prepared for a shock! Because some of you believe that Optical/DWDM box can be the most closed platform in networking. After all, an optical signal is analog (not digital) therefore it is difficult to understand it. And since vendors use proprietary enhancements to carry signals; therefore, it is […]
So you are in a sprint mode for deploying virtual CPE ( Customer Premises Equipment)? You, as an operator, want it FAST. As you want to cut your CAPEX/OPEX or perhaps you want to provision services faster. But, something is holding you:
In April 2002, a nationwide disruption hit AT&T that lasted 3 hours because of the misconfiguration of OSPF in a backbone router. In February 2009, a misconfigured router from SuproNet, a Czech ISP, caused internet services outages worldwide. In 2014, a misconfigured router in China affects 618 Million internet users for 8 hours. All above […]
The large web scale companies like Facebook, Amazon and Google love them. The traditional networking vendors hate them as they consider them a threat. The truth is that they have become significant in this age of SDN , thanks to their “Open Platform” concept. Therefore it is important to understand the basic concept of a […]
A beginner of NFV journey faces two obstacles when trying to understanding NFV Management & Orchestration (NFV MANO): First, he knows already that a traditional network needs just one management system i.e. an EMS (or an NMS) or at most supported by an OSS. The NFV network, on the other hand, needs multiple managers i.e. […]
Short on time? Need a quick refresher on NFV (Network Functions Virtualization) terminology/ architecture in easy to understand language? Then find below a summary of SEVEN key blocks in NFV architecture, which is all you need to know to get started with the NFV architectural framework. Follow the block numbers and definitions below. But before […]
Honestly yes! One router may kill the other router, sooner or later. The “Virtual Router” is showing the performance and power required for carrier grade networks. So, if you are planning to acquire routers, read on, as you will get useful information on the options you have at hand, now. In this blog, I question […]
So you have your next appointment with a Transport/optics vendor for a presentation on its Transport SDN roadmap. And you are all set to explore the rosy picture the vendor wants to present about its Transport SDN’s roadmap. Therefore, it’s time to do some homework, so you can ask right questions from the vendor […]
