Carrier Ethernet – Definition | Service Types | Requirements

CARRIER ETHERNET DEFINITION

Carrier Ethernet is an attempt to expand Ethernet beyond the borders of Local Area Network (LAN), into the Wide Area Networks (WAN).

With Carrier Ethernet, customer sites are connected through the Wide Area Network. Carriers have connected the customers with ATM (Asynchronous Transfer Mode) and Frame Relay interfaces in the past. (User to Network Interface/UNI).

Carrier Ethernet is not about the Ethernet within the Local Area Networks.

Driver of Carrier Ethernet is; since Ethernet is the de-facto protocol on the Local Area Network, why not to use Ethernet everywhere, and not only within LAN. When any other Wide Area Network protocol is used such as ATM, customer Ethernet frame is encapsulated into another protocol.

This reduces the overall efficiency of customer service, consumes more network bandwidth, makes troubleshooting harder and many other drawbacks.

Carrier Ethernet is also known as Carrier Class Ethernet and Carrier Grade Ethernet.

Another reason for Carrier Ethernet is; Ethernet interfaces and the devices are cheaper compare to the other technologies. This result cheaper service to the customers.

CARRIER ETHERNET REQUIREMENTS  

Traditional Ethernet lacks many features which are required to transport critical services, time sensitive applications and voice services.

These are:

  • Traffic Engineering
  • Bandwidth Guarantee
  • Quality of Service
  • OAM
  • Decoupling of Providing and Customer Networks
  • Continue reading

What is Colocation, POP , Carrier Hotels and Meetme Room ?

What is Colocation, POP , Carrier Hotels and Meetme Room ?

If you are working in operator domain or a network engineer who wants to learn what is colocation , what is POP (Point of Presence) , how POPs are physically connected , POP terminology , understand meetme room and carrier hotel, this post is for you.

POP locations can be located in the Datacenter or in very small buildings , meetme room and the carrier hotel is placed in the datacenter.

Colocation is provided by the datacenters.

But there are other details which you should be aware.

I explained these details in the below video. This video is one of the 20 topics from the network interconnection module of Service Provider Design Workshop. You can take this workshop and watch the on demand 10+hours service provider technology videos right away.

A Roadmap for Building Modern Applications

Photo by Alvaro Reyes on Unsplash

No matter what industry you’re in, your application modernization strategy matters. Overlooking or downplaying its importance is a quick way for customers to sour and competitors to gain an edge. It’s why 91% of executives believe their revenues will take a hit without successful digital transformation.

The good news is modern applications offer a clear path forward. Creating a roadmap for your modern application strategy is a critical step toward a more agile and continuous model of software development and delivery – one that’s centered on delivering perpetually expanding value and new experiences to customers. 

This is the first of a series of blogs where we will look at industry viewpoints, different approaches, underlying platforms and real-world stories that are foundational to successful modern application development in order to provide a roadmap for application modernization.

What’s in Your Environment? 

The technology inventory at companies today is as diverse, distributed and complex as ever. It includes a variety of technology stacks, application frameworks, services and languages. During a modernization process, new Open Source technologies are often integrated with legacy solutions. Existing applications need to be maintained and enhanced, modern applications need to be Continue reading

Social Media Crisis Drives Ongoing Decline In Global Internet Freedom

Global Internet freedom declined for the ninth consecutive year in 2019, largely as a result of social media increasingly being used by governments around the world as a conduit for mass surveillance and electoral manipulation. The Freedom on the Net 2019 report, the latest edition of the annual country-by-country assessment of Internet freedom, was released on November 5 by Freedom House, and highlights the shift in social media from a level playing field for civic discussion to an instrument of political distortion and societal control.

The Freedom on the Net 2019 report analyzed Internet freedom in 65 countries worldwide, covering 87% of global Internet users. Surveyed countries are designated as ‘Free’, ‘Partly Free’, or ‘Not Free’ based on an examination of, and scoring against, three categories: obstacles to access, limits on content, and violations of user rights.

Of the 65 countries assessed, 33 of them saw Internet freedom decline over the last year, with the biggest drops observed in Sudan and Kazakhstan. The longtime presidents of both countries were ousted, leading to widespread blocking of social media platforms, disruptions of Internet connectivity, and the increased use of electronic surveillance to undermine free expression.

The report called digital platforms Continue reading

SEC 2. Data plane and control plane protection in the networking (Nokia, Cisco and Mellanox/Cumulus) for IPv6.

Hello my friend,

After the release of the previous article outlining the data and control plane security for IPv4 in Cisco, Nokia and Mellanox/Cumulus (link) I’ve got several requests about the security in IPv6. The requests were fair enough and with this article we close this gap.

Arista targets cloud networking with CloudEOS software

Arista this week rolled out software it hopes will help customers more easily fuse enterprise-class networking with on-premises and hybrid-cloud services.The company rolled out two new packages. One, CloudEOS Multi Cloud, normalizes the network connectivity to and between private clouds or public clouds. The package sets up a virtual machine and can redirect traffic across the most effective and efficient networking path using real-time topology, in-band telemetry and other attributes, the company said. It also automatically encrypts all traffic on those paths as well. To read this article in full, please click here

Cheap IoT satellite network gets approval

Space communications start-up Swarm Technologies will begin delivering commercial, bi-directional Internet of Things (IoT) data early next year, according to the company, which has just received its regulatory go-ahead to launch its satellites and transmit.“Swarm will begin rolling out its commercial, two-way data offerings in early 2020,” Sara Spangelo, co-founder and CEO told me in a recent e-mail. The company aims to deploy 150 satellites before the end of 2020, she says. The FCC, in October, granted Part 25 approval for the startup to deploy and operate 150 non-geostationary, Low Earth Orbit (LEO) satellites, for non-voice purposes.To read this article in full, please click here
