Rough Guide to IETF 99: Scalability & Performance
In this post I'll highlight some of the Internet Engineering Task Force (IETF) and Internet Research Task Force (IRTF) groups meeting during the IETF 99 meeting in Prague next week. These groups are working to explore and address more sophisticated ways to use and share available bandwidth, improve Internet performance, and otherwise efficiently get Internet content to where it needs to be.

Rough Guide to IETF 99: Internet of Things
The Internet of Things (IoT) is a buzzword around the Internet industry and the broader technology and innovation business. We are often asked what the IETF is doing in relation to IoT and in this short post I'd like to highlight some of the relevant sessions scheduled during the upcoming IETF 99 meeting in Prague. Check out the IETF Journal IoT Category or the Internet Society's IoT page for more details about many of these topics.

Rough Guide to IETF 99: Back to Prague
Time to get ready for IETF 99! Starting a week from today, on Sunday, 16 July, the Internet Engineering Task Force will be in Prague, Czech Republic, where about 1000 engineers will spend a week discussing the latest issues in open standards and protocols. As usual, the agenda is packed, and the Internet Society is providing a ‘Rough Guide’ to the IETF via a series of blog posts all this week on topics of mutual interest:

Why Do You Still Blog?
After recording an excellent session on social media at Cisco Live with The Network Collective (@NetCollectivePC), I started thinking about blogging and where it stands in the grand scheme of information sharing. With the rise of podcasting and video blogging now in full swing, I was even asked by my friend Michael Stump “Do you see blogging as a dying form of content?” For obvious reasons, I said “no”, but I wanted to explain two major reasons why.
Needle In A Haystack
One of the major reasons why I still blog through written form is searchability. When I started blogging almost seven years ago I wanted to create a place where I could put down my thoughts about topics and share them with everyone. More by accident than design, many of those thoughts became popular topics of conversation. Even today, some of my posts are being used to help people figure out problems and address issues that aren’t well documented in other places.
But why? How can posts many years old still be relevant to audiences today? Because of searching. Use of Google, DuckDuckGo, and even Bing allow people to search for specific error messages Continue reading

Amazon Delivery, Not a Fully Implemented Process
Those of us who work in technology see the need to take expensive, time consuming and/or mundane activities and convert them to streamlined automated processes. Ideally we improve these to the point that they improve accuracy, provide a better experience and can [mostly] be forgotten about. However, not every process fits all of the intended use cases. Maybe a more accurate statement might be that every process isn’t developed to fit every use case. For those of us who are outliers and find ourselves in those process deficiencies, these incomplete processes can create a lot of frustration.
A Little Background
I’ve been an Amazon Prime user for some period of time. I have also been free of a home mailbox for about 18 months and only used a PO Box to receive general mail. As a Prime customer, I regularly place orders with Amazon. Anyone else that has had the experience I’m about to share can probably finish my story.
The Problem
The problem with this scenario is that each order can only have one delivery address. When the order is placed, there is no way to select the delivery mechanism. So if I list my physical home address, I have Continue reading

Comparison: Cisco Catalyst 9500 Vs Cisco Catalyst 4500 Vs Cisco 3850 Switches
Today I am going to talk about the fixed core chassis Cisco catalyst 9500 which Cisco released a month back. Cisco 9500 is actually enhanced version of Cisco catalyst 4500 chassis and also Cisco 3850 Switch. There are lot of other best features in Cisco 9500 Chassis as some of the features are just amazing in this device.
So we have Cisco 3850, Cisco 4500 Catalyst Switches, Cisco 6500 Catalyst switches, Cisco 6800 Catalyst switches and now Cisco 9000 catalyst switches with 3 flavours ( Cisco 9300 catalyst switches, Cisco 9400 catalyst switches and Cisco 9500 Catalyst switches)
How topology and the demand changes, below is the example topology showing the changes which leads to the next generation fabric network with cloud ready solutions and automation. CLI is gone for the campus fabric, All policy is driven with the SDN controller.
If we have Cisco 4500 and Cisco 3850 fixed chassis why we required Cisco 9500 chassis ?
I knew this is one of the question which you actually thinking and for this i would like to say that you need to understand the next generation campus requirements where customer wants to be Continue reading

Hit Pause: Take a Moment to Reflect on the Repercussions of the Recent Ransomware Attacks
As these devastating global ransomware attacks illustrate, cybersecurity is not an issue that can be ignored. Any time a device or system is connected to the Internet, it is a potential target. What was once just another lucrative means of extorting money from Internet users, ransomware is emerging as a preferred tool for causing widespread disruption of vital services such as hospitals, banks, shipping, or airports. Attacks are growing more sophisticated and more enduring, with longer term damaging effects and wider impact. Ransomware exploits the slow pace of security patching, systems that are dependent on old software, and poor backup practices.
