Failover Mechanism Part-1

Redundancy is must for ISP in Core and also its equally important for Enterprise
to have network up always thus resulting in zero business impact due to network outage.
There are  different scenarios of failover mechanism  depending upon the  requirement.
First of its kind is Dual POP Dual last mile Dual CE (DPDLDC). It provides redundancy both for WAN connectivity as well as LAN connectivity.

DUAL POP—customer  primary and secondary link terminated on different PE router.

DUAL LAST MILE—last mile connectivity between PE and CE is different for primary and secondary

DUAL CE -Primary and secondary terminated on different CPE device.

I would be sharing Multiple Scenarios of Fail over Mechanism in coming  posts.

ISP is very much transparent in this scenario, traffic control is being done from CPE end.

Considering the below  topology

Failover Mechanism —

1. Outgoing Traffic from CPE wan is controlled using HSRP + IP SLA
2. Incoming traffic to CPE is controlled using AS Path Prepend attribute of BGP at secondary( lower as path count , better path)
Normal Scenerio
1)Primary WAN link is up .HSRP running towards LAN is active state. Secondary link is having AS-Prepend so primary link is preferred with having less number Continue reading

IDC: Cloud is eating legacy systems

New research from IDC shows that spending on infrastructure to run public and private clouds continues to grow at leaps and bounds as spending on non-cloud infrastructure decreases.  +MORE AT NETWORK WORLD: 10 Best Cloud SLA practices + IDC’s Worldwide Quarterly Cloud IT Infrastructure Tracker tracks spending patterns of users and service providers, along with revenues of vendors to paint a picture of cloud adoption trends. Infrastructure spending on public and private cloud technology – which includes servers, storage and Ethernet switching – grew 21.9% in 2015 to be a $29 billion industry. Cloud technology made up almost one-third (32%) of all IT infrastructure sales; that’s up from $28.6% in 2014.To read this article in full or to leave a comment, please click here

The battle between LTE and Wi-Fi may have left LTE-U out in the cold

After more than a year of rancor over whether it would hurt Wi-Fi, a technology that lets LTE networks use unlicensed spectrum may have already missed its window of opportunity.LTE-Unlicensed is designed to improve cellular service by tapping into some of the frequencies used by Wi-Fi and other unlicensed technologies. But almost as soon as LTE-U was proposed in late 2014, Wi-Fi supporters pounced. They charged that it would drown out Wi-Fi signals because LTE didn’t know how to make room for other users.+ PRIMER: LTE-U: A quick explainer +To read this article in full or to leave a comment, please click here

Worth Reading: ‘net Morality

I have come to the conclusion that “net neutrality” is an ethical issue at heart, one about the appropriate constraint of unfair ISP power. Some people are (I pray unintentionally) on the wrong side of a now-clear moral divide. They are claiming to prevent harmful abuse of power, when in reality their actions create fresh harm.

How to manage IT in a growing business: Implementing IT policies

Although vendor-written, this contributed piece does not promote a product or service and has been edited and approved by Network World editors. As business leaders grow their companies, corporate assets should always be top of mind. As such, business leaders should be implementing IT policies early on in order to set standards and expectations for employees when it comes to the use of corporate technology and managing corporate data. In parts one and two of this three-part series, I rolled out a playbook on when companies should hire their first IT consultant and what to keep in mind when appointing a CIO. In this third and final part of this series on the IT Lifecycle I’ll discuss when companies should start rolling out formal IT policies and how to do so.To read this article in full or to leave a comment, please click here

How to manage IT in a growing business: Appointing a CIO

Although vendor-written, this contributed piece does not promote a product or service and has been edited and approved by Network World editors. Timing is everything when hiring a CIO. The primary function of a CIO is to be forward-looking for developing and implementing IT initiatives, but it can be difficult for a CIO to fulfill this duty if he or she is brought in too late and provided with inadequate technologies and processes. The earlier a company invests in a CIO, the earlier everyone can be in tune with what will make the business most efficient. But most companies don’t know when it’s too early and when it’s too late. In the first article of this three-part series on the IT Lifecycle, I discussed recommendations for when to hire an IT consultant, and what to consider when doing so. During this process, it’s important to recognize when a CIO will be a valuable addition. In this second part of the series, I will continue to follow Joe’s Widget Shop, a hypothetical software development company, as they move onto the next stage in the IT lifecycle. I’ll provide you with insight on what to look for when appointing a CIO Continue reading

DARPA moves toward spacecraft that can fly 10X in 10-days

DARPA this month will explain what it wants in the next development phase of its reusable Mach 10 satellite taxi capable of carrying and deploying a 3,000- 5,000 lb. satellite into low earth orbit (LEO) at a target cost of less than $5M per launch.+More on Network World: DARPA: Show us how to weaponize benign technologies+DARPA’s Experimental Spaceplane (XS-1) system would have a reusable first stage that would fly to hypersonic speeds at a suborbital altitude. At that point, one or more expendable upper stages would separate and deploy a satellite LEO. The reusable first stage would then return to earth, land and be prepared for the next flight. Modular components, durable thermal protection systems and automatic launch, flight and recovery systems should significantly reduce logistical needs, enabling rapid turnaround between flights.To read this article in full or to leave a comment, please click here

Although vendor-written, this contributed piece does not promote a product or service and has been edited and approved by Network World editors. Few companies are founded with a CIO. For many, the first IT “hire” is the company’s founder, whose job description may include activities like IT purchasing, networking and IT support, alongside planning, marketing and business development. Eventually, that changes. But when? And how? In my role as a chief operations officer, I’ve helped many companies build out their IT operations as they grow from startups to SMBs and beyond.

FishNet: Single Page Resources for all Things Fishy on the Net

Introducing to Networking with Fish a new page —- “FishNet”. 

What is FishNet? Imagine “casting a net” out on the Internet for all “Fishy IPv6” – in other words… for all the stuff I’ve written, taught (CiscoLive), or YouTube’d that is IPv6 that is somewhere out on the internet.

Topics thus far that I’ve cast a net out hauled in thus far are BGP, DMVPN, IPv6, IWAN, Multicast, and Troubleshooting.      I’ll be keeping them current as a “single source” for all things “Fishy” out on the internet for those topics.

Happy nerding!

This little robot wants to help you shop

SoftBank's Pepper robot may still be the better-known contender, but a new humanoid device from Hitachi aims to be the in-store sales rep of the future.Called EMIEW3, the roughly 3-foot-tall unit can determine when customers need help and then approach them autonomously, Hitachi said on Friday. Using what it calls "remote brain" technology, the company developed the robot with customer service in mind for use in stores and other public venues.EMIEW3 is actually the latest iteration in a series following Hitachi's introduction of the original EMIEW back in 2005.

Free Google Fiber is not in Kansas anymore

The free ride is over for new Google Fiber subscribers in Kansas, as Google drops the free “Basic Internet” option from its plans.Google has offered the free plan since Fiber first launched in July 2012. Compared to Google’s $70 per month Gigabit Internet offering, the free plan was considerably slower, with just 5 Mbps download speeds and 1 Mbps upload speeds. It also required a hefty $300 construction fee, which Google waived for paying customers who signed on for at least a year of service.According to Recode, that plan is now going away for new subscribers, suggesting that existing customers can hang onto their service for now.
