NEWS UPDATE: The impact of COVID-19 on public networks and security

As the coronavirus spreads, public and private companies as well as government entities are requiring employees to work from home, putting unforeseen strain on all manner of networking technologies and causing bandwidth and security concerns.  What follows is a round-up of news and traffic updates that Network World will update as needed to help keep up with the ever-changing situation.  Check back frequently!UPDATE: 3.26 Week over week (ending March 23) Ookla says it has started to see a degradation of mobile and fixed-broadband performance worldwide. More detail on specific locations is available below. Comparing the week of March 16 to the week of March 9, mean download speed over mobile and fixed broadband decreased in Canada and the U.S. while both remained relatively flat in Mexico. What is the impact of the coronavirus on corporate network planning? Depends on how long the work-from-home mandate goes on really. Tom Nolle, president of CIMI Corp. takes an interesting look at the situation saying the shutdown “could eventually produce a major uptick for SD-WAN services, particularly in [managed service provider]    Businesses would be much more likely to embark on an SD-WAN VPN adventure that didn’t involve purchase/licensing, Continue reading

ROLLING UPDATE: The impact of COVID-19 on public networks and security

As the coronavirus spreads, public and private companies as well as government entities are requiring employees to work from home, putting unforeseen strain on all manner of networking technologies and causing bandwidth and security concerns.  What follows is a round-up of news and traffic updates that Network World will update as needed to help keep up with the ever-changing situation.  Check back frequently!UPDATE 3.27Broadband watchers at BroadbandNow say users in most of the cities it analyzed are experiencing normal network conditions, suggesting that ISP’s (and their networks) are holding up to the shifting demand. In a March 25 post the firm wrote: “Encouragingly, many of the areas hit hardest by the spread of the coronavirus are holding up to increased network demand. Cities like Los Angeles, Chicago, Brooklyn, and San Francisco have all experienced little or no disruption. New York City,  now the epicenter of the virus in the U.S., has seen a 24% dip out of its previous ten-week range. However, with a new median speed of nearly 52 Mbps, home connections still appear to be holding up overall.”To read this article in full, please click here

How enterprise networking is changing with a work-at-home workforce

As the coronavirus spreads, public and private companies as well as government entities are requiring employees to work from home, putting unforeseen strain on all manner of networking technologies and causing bandwidth and security concerns.  What follows is a round-up of news and traffic updates that Network World will update as needed to help keep up with the ever-changing situation.  Check back frequently!UPDATE 4.3 In an April 2nd call with the Federal Communications Commission chair, the nation’s largest telecom and broadband providers reported network usage during the COVID-19 pandemic had risen about 20-35% for fixed networks and 10-20% for cellular networks in recent weeks. In general, company representatives reported that their networks were holding up quite well, and they expected that resilience to continue. In their conversation with Chairman Ajit Pai, no providers expressed concern about their networks’ ability to hold up to increased and changing demand. To read this article in full, please click here

Day Two Cloud 041: Practical Automation In The Cloud And On Premises

On today's Day Two Cloud, we discuss practical automation, including tools and tips to make automation work. In particular, we focus on deploying consistent builds for VMs across public cloud providers and on premises. We also examine key issues such as the need to close the loop on automation processes, and how to ensure that one person doesn't become irreplaceable. Our guest is Larry Smith, Senior DevOps Engineer.

Working with APRICOT to Improve Routing Security

We’re pleased to announce that the Internet Society and the Asia Pacific Network Operators Group Ltd (APNOG) signed a Memorandum of Understanding (MoU) to cooperate in supporting the MANRS initiative in the Asia-Pacific region.

APNOG is the non-profit entity that runs the annual APRICOT conference, also called the Asia-Pacific Regional Internet Conference on Operational Technologies. APRICOT is the largest meeting of the technical community in the region.

The agreement will see the two undertake initiatives and activities to promote the security of the Internet’s global routing system and Mutually Agreed Norms for Routing Security (MANRS). MANRS is a global initiative, supported by the Internet Society, that provides crucial fixes to reduce the most common routing threats.

We agree to tackle routing-related cybersecurity incidents such as route hijacking, route leaks, IP address spoofing, and other harmful activities that can lead to DDoS attacks, traffic inspection, lost revenue, reputational damage, and more.

APRICOT draws many of the world’s best Internet engineers, operators, researchers, service providers, and policy enthusiasts from around the world to share the technical knowledge needed to run and expand the Internet securely. The partnership will allow MANRS to better leverage the platform to promote routing security to conference participants, Continue reading

Comparing Internet Connection used in AWS and LISP Based Networks


Forewords

This post starts by discussing the Internet connection from the AWS VPC Control Plane operation perspective. The public AWS documentation only describes the basic components, such as an  Internet Gateway (IGW) and a subnet specific Implicit Routers. However, the public AWS documentation does not describe the Control Plane operation related to distributing the default route from IGWs to IMRs. The AWS VPC Control Plane part in this post is based on my assumptions, so be critical of what you read. The second part of this post shortly explains the Control-Plane operation of the Internet connection used in LISP based network. By comparing the AWS VPC to LISP based network I just want to point out that even though some might think that cloud-based networking is much simple than traditional on-premise networking, it is not. People tend to trust network solutions used in clouds (AWS, Azure, etc.) and there is no debate about (a) what hardware is used, (b) how the redundancy works, (c),  are solutions standard-based and so on. Now it is more like, I do not care how it works as long as it works. Good or bad, I do not know.
