3). Intro to SDN (Software Defined Networking) Basics–SDN & Openflow Architecture [VIDEO]
Software defined networking (SDN) SDN (software defined networking) is highly correlated with NFV. SDN is a big deal in IT and Telecom. NFV is all about building up virtual platforms. SDN is about making IP networks more flexible, more customizable, more programmable so that packet routing is possible with lots of flexibility and agility. Imagine a router, a physical piece of hardware, specifically designed and manufactured for implementing software functions that allow us control over the delivery of our data packets at its core. SDN now allows us to extract the software function from the actual piece of hardware. Now, we can take this extracted software function and apply it…

2). Intro to NFV (Network Functions Virtualization) Basic Concepts–NFV Architecture [VIDEO]
Network functions virtualization (NFV) Network functions virtualization (NFV) is a procedure that increases and improves network function by managing networks. NFV is an architectural framework providing a reference model where network functions are delivered through software…. The NFV framework was first developed by the ETSI (European Telecom Standards Institute) NFV Industry Specification Group set up in 2012. [1] There’s a lot of info on the internet about NFV and we culled together some sources through this post. Also, included is a great series of videos on YouTube giving a quick intro to telecommunication cloud basics. The videos feature Vikas Shokeen and are available in short 4-video series, with the second…

1). Intro to Telco (Telecommunications Company) Cloud Basics, NFV, SDN, Architecture of Cloud Networks [VIDEO]
There’s a great series of videos on YouTube giving a quick intro to telecommunication cloud basics. The videos feature Vikas Shokeen and are available in short 4-video series. The first one is below with some basic notes. Architecture of Cloud Network for Telcos Telco–a telecommunications company (informal) Telecom–general telecommunications (informal) (Note: As with many terms in the tech industry, “telco” and “telecom” are sometimes used interchangeably in common-day speech. Don’t get too twisted up over it. Dig deep into what’s underneath.) Telco Cloud: Basics Introduction Why cloud? Mobile Operators Benefits Overview Cloud–a network “out there”. Properties of cloud networks Properties of cloud networks include: No Dedicated Hardware Shared Resources Convenient…

What is “Vendor Neutral”?
What does it mean to be Vendor Neutral? To be Vendor Neutral, or Vendor Neutrality, seems like it should mean no specific preference to any certain vendor or no bias towards any certain particular vendors, or not favoring one vendor over another. Indeed, vendor neutral means a “product or specification that is not proprietary and controlled by one company. Open source software was conceived to avoid allegiance to a single vendor”[14]. PC Mag encyclopedia goes on to make note, “However, an ‘open system’ is not entirely vendor neutral as the foundation platform may be controlled by one company”.

What is a Tier 1 network?
What is a Tier 1 network? A Tier 1 network is “an IP (Internet Protocol) network that can reach every other network on the Internet solely via settlement-free interconnection”[2] (that is, they can reach the entire internet via settlement-free peering). You can think of Tier 1 networks as having a kind of “golden VIP pass” with each other, and each Tier 1 network can exchange traffic with other Tier 1 networks without paying any fees for the exchange of traffic in either direction. (This contrasts with some Tier 2 networks and all Tier 3 networks which must pay to transmit traffic on other networks.) Universally recognized Tier 1 networks include…

What is a data center? And Why Are They So Important??
Many people may have heard the term “data center” but most don’t really know what that means. Nonetheless, these data centers are incredibly important to our everyday way of life. What is a data center? Data centers are these vast, huge, sometimes-sprawling buildings dedicated to holding the back-end computer systems, machinery and associated components needed to help run what we consumers know of as “the internet”. In a way these data centers are “the cloud” that we think of when we say our info is “stored out there…in the cloud”, and these data centers can use as much electricity as a small town. What is colocation? A colocation data center…

What is “the cloud”? #Cloud #CloudComputing #CloudNetworking
The cloud. Conjures up all kinds of memories of looking toward the sky and gazing at these constantly evolving, ephemeral, floating objects. In the tech world some terms are flexible and can be a bit tricky, or hard to contain to one concrete definition. The “cloud” is a network “out there”. Indeed the very internet itself can be the cloud in some ways. Many consumers quickly warmed up to cloud with the easy adoption of web-based email like “Gmail” which is essentially “email in the cloud”. Instead of being stored on our local machines, we became used to storing our email with Google in their “cloud”. But a “cloud” has…

What are the Different Types of Computer Networks?
Well, first, what a great question! There are NUMEROUS different types of networks, just speaking of the technical kind specifically! While all computers essentially need DATA to be useful, it is when two (or more!) computers are connected to each other, that they can exchange/share data and thus compounding/magnifying their usefulness. CAN—Campus Area Network LAN—Local Area Network MAN—Metropolitan Area Network WAN-Wide Area Network SD-WAN—Software Defined Wide Area Network

What is Blockchain Technology?
Cryptocurrency a medium of exchange; a digital asset. its created & stored electronically in the blockchain, using encryption techniques to control the creation of monetary units and to verify the transfer of funds. (Bitcoin is the most widely know example.) Cryptocurrency has no intrinsic value (meaning not redeemable for another commodity, such as gold). It has no physical form (and exists only in the network). Cryptocurrency is DECENTRALIZED. It’s supply is not determined by a central bank; the network is completely decentralized. Blockchain–a distributed ledger technology; a database that is shared, replicated and in-sync. Blockchain–a blockchain is a decentralized ledger of all transactions across a peer-to-peer network. By using blockchain…
