My Current IWAN Analogies

I use analogies. Just how my brain works…. and how I sometimes learn and teach.  Token-ring source-route bridging analogy was “breadcrumbs thru the network”. Analogy for DLSw+ was a boat getting the breadcrumbs over water between 2 islands.

I think I like analogies cause…. to be superbly honest… when I came to work at Cisco back in 1996 I only knew SNA.  I did NOT know IP.  I was quickly immersed into learning IP. But I mean seriously… using acronyms to explain other acronyms you don’t understand? Don’t get me started!

Ready to play? Yea yea… my brain jumps around with varying analogies. If one doesn’t hit ya maybe the next will.  :)  Happy nerding!

 

Waze on Steroids

wazeImagine you own a rental car agency with 2 locations across town from each other. Your employees are constantly driving the cars back and forth between the two locations to balance out inventory.

If the employees hit issues during the drive (potholes, glass, mud, sand, dirt, major traffic, construction) this is going to cost your company.

So you can see how knowing what is going on via the varying paths between your locations is critical to your Continue reading

Microsoft’s ‘blue screen of death’ is getting more descriptive with QR codes

The Windows Blue Screen of Death isn't known for being particularly descriptive, but Microsoft may be looking to change that in a future version of Windows 10.  A Reddit user posted a picture last week that shows a new version of the dreaded blue screen, one with a QR code and a link where users can get more information about the error that caused their computer to crash.  Right now, the code and the link take users to a webpage that discusses generic fixes for errors that might cause a crash. In the future, though, Microsoft could provide a QR code that leads to more specific information about what caused the computer freeze up.To read this article in full or to leave a comment, please click here

Microsoft endorses EU-US Privacy Shield data sharing pact

Microsoft is throwing its weight behind the EU-U.S. Privacy Shield agreement, which is intended to safeguard the privacy of European Union citizens when their personal information is exported to the U.S. for processing.But a document leaked late last week suggests the proposed agreement does not have the backing of EU data protection authorities, who are meeting this week to finalize their position on it.Microsoft will seek approval to conduct data transfers under the agreement, its Vice President for EU Government Affairs, John Frank, wrote in a blog post Monday.To read this article in full or to leave a comment, please click here

Taipei: CloudFlare’s 77th Data Center is Now Live

台北：CloudFlare的第七十七個數據中心已經上線喔！

alt

We are excited to announce the launch of our Taipei data center, which is our 28th data center in Asia, and our 77th data center globally. Millions of websites which were previously served from Hong Kong are now served locally from Taipei.

我們高興地宣布CloudFlare的的台北機房建置完成。這是我們在亞洲的第二十八個，在全球的第七十七個數據中心。從現在起台灣的網民可以直接從CloudFlare在台北的節點訪問數以百萬計的網站，不再繞道到香港。

Taipei today
今天的台北

Taipei, home to many renowned tech companies, is famous not only for its vibrant night markets, but also for its warm and welcoming people. From soup dumplings to computer peripherals to Kangsi Coming, its contribution to the world is enormous.

科技重鎮台北，不單擁用充滿活力的夜市，台北人的熱情而友善的人情味也是舉世聞名的。從小籠包、電腦周邊零件到康熙來了，台北對世界的貢獻碩大無朋。

Improved availability and performance
更進一步的可用性和性能

Taipei has one of the fastest Internet speeds. Yet, being located far away from other Internet interconnect centers makes for some unique challenges. When traffic is delivered to local eyeballs from Hong Kong, Tokyo, Singapore or worse-still Los Angeles, it is often subject to long latency and the constraints of limited capacity before arriving in Taipei. Additionally, traffic flowing on undersea cables around Taipei have been subject to cable cuts over the years, mainly because of the active fault lines around the island.

台北有世界上首屈一指的網路速度。可是，因為台北和其他互聯網交換中心的距離，來自香港，東京，甚至洛杉磯的流量往往要通過高延時和有限的頻寬才能傳送到台北。另外，台北位於板塊交界處，地震發生頻繁，海底電䌫中斷時有發生。

With the launch of our Taipei data center, visitors to millions of CloudFlare websites will experience a 4x improvement in performance and Continue reading

Spark On Superdome X Previews In-Memory On The Machine

As readers of The Next Platform are well aware, Hewlett Packard Enterprise is staking a lot of the future of its systems business on The Machine, which embodies the evolving concepts for disaggregated and composable systems that are heavy on persistent storage that sometimes functions like shared memory, on various kinds of compute, and on the interconnects between the two.

To get a sense of how The Machine might do on in-memory workloads that normally run on clusters that have their memory distributed, researchers at HPE Labs have fired up the Spark in-memory framework on a Superdome X shared …

Spark On Superdome X Previews In-Memory On The Machine was written by Timothy Prickett Morgan at The Next Platform.

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

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

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
