General – Advice on Numbering Policies in Networking

There are several situations where we need to write some form of policy such as QoS, routing policies used in for example redistribution, filtering and policy-based routing, dot1x and so on. Lately I had to update a policy used by the master controller (MC) in an IWAN design. What are some important things to consider when writing the policy?

The number to start with – If you start with the number one then it won’t be possible to insert anything above this line at a later time. How certain are you that you will never have to put anything before the starting line? My recommendation is to start with a higher number such as 100.

Space between each line – Don’t number your lines 100, 101, 102, 103 and so on. Leave some more space between each line in case you have to insert something later between two lines. A spacing of 10 should be fine for most situations.

Go from most granular to least granular – The policy should go from as granular as possible to the least granular at the end. If you have a statement that is too broad you may catch more than you expected even Continue reading

Introduction to Next Generation Network Technology: IOT- Internet Of Things

Today I am going to talk about the next generation technology where we are going to connect many other infrastructure and electronic things and controlled and managed by single user or with group of the users. IOT is now the demand of many enterprise, Schools, Hospitals, Factories and many other places. IOT helps ease to work with the help of the latest technology.

IOT is the new technology where we automated the various appliances may be electronic and electric to make this world better. A aspect, within the internet of things, can be someone with a heart monitor implant, a farm animal with a biochip transponder, an car that has built-in sensors to alert the driver whilst tire pressure is low -- or every other natural or guy-made item that can be assigned an IP address and provided with the capacity to switch facts over a network.

The IoT permits objects to be sensed and managed remotely across current network infrastructure, developing opportunities for extra direct integration of the physical global into pc-based totally systems, and resulting in improved efficiency, accuracy and financial advantage.

What is the Basic Purpose of IOT ? How it will helpful for my Business ?

The Use of the Asymmetric routing

Today I am going to talk about the the concept of asymmetric routing and what is the purpose of the asymmetric routing in details. In simple words, Asymmetric routing is used when a packet takes one path to the destination and takes another path when returning to the source. It can be used of manual purposes where we want the sending and the receiving path will be different.

Asymmetric routing is common within most networks i.e. the larger the network, the more likely there is asymmetric routing in the network. Asymmetric routing is an undesirable situation for many network devices including, firewalls, VPNs, and Load Balancer appliances. These devices all rely on seeing every packet to function properly. 

Below is the example showing the asymmetric routing where we have two different paths for sending and receiving the packets or you can say traffic flow path are different for sending and receiving the packets. In the below topology, you can see that Site A sending the traffic to internet via Primary Router and then to ASA and then to internet Router while receiving from Internet router then secondary router and then to Site A via MPLS cloud. So this Continue reading

Hive Mind, Help Me Out with A10 AXAPI?

Dear Internet,

I am writing some automation code in Go to create client-ssl templates on an A10 load balancer running AXAPI version 2. It’s going as swimmingly as it can with the v2 API, but one area of non-complete API coverage has led to another issue and I’m wondering if anybody has seen the same thing.

Background – Disabling SSLv3

SSL access to VIPs on the A10 load balancer is controlled by means of client-ssl templates which define which certificates should be presented and the ciphers and protocols supported for the incoming connection. In this case therefore, disabling SSLv3 is accomplished in the client-ssl template (unfortunately there is no global switch to turn SSLv3 off by default). A typical template might look like this in the configuration:

slb template client-ssl mytemplate
   cert my_certificate
   key my_private_key
   chain-cert some_chain_cert
   disable-sslv3
!

As it turns out, all aspects of the client-ssl template are exposed via the API except for “disable-sslv3” which shows neither as a returned property of the template (highly annoying), nor as a property which can be set when creating a template (also annoying). Thus to replicate a template like the one above, I choose to set everything I can using the Continue reading

New IBM platform turns your data center into a cloud

What if you could flip a switch and turn your stodgy old data center full of legacy apps into a cloud-enabled one capable of migrating apps and data to the public cloud with ease by containerizing your legacy apps?IBM says it has just such an offering in IBM Cloud Private, a platform focused on assisting private data centers looking for a relatively simple way to move into the cloud. The idea is to offer a consistent way of managing your application stack, regardless of where they reside. Also on Network World: IBM’s latest private cloud is built on Kubernetes, and is aimed at Microsoft IBM Cloud Private takes middleware and other legacy applications, places them inside Kubernetes containers and transforms them into contemporary applications using Kubernetes container orchestration. The software itself is already containerized, including IBM tools and most major open source databases. To read this article in full or to leave a comment, please click here

Fujitsu, NetApp Tag Team For Converged Infrastructure

Converged and hyperconverged infrastructure, those tightly integrated systems that bring together compute and storage into pre-tested and pre-configured stacks, continues to be in high demand from enterprises that are looking to rework their datacenters to become private clouds that can more easily and, in the long run, more cheaply host fast-emerging technologies like analytics, mobile applications, Internet of Things telemetry, virtual and augmented reality, and various software-defined infrastructure. These CI and HCI platforms are designed to bring greater flexibility and scalability, ease deployment and management, and reduce costs in areas such as acquisition and power consumption.

IDC analysts have been …

I’m Planning to Change the World

Earlier this week, the Internet Society published the booklet Enabling Digital Opportunities in the Middle East. Using research created by the Internet Society, ESCWA, and Wamda, it shows what positive and practical steps can be taken to increase digital opportunity and spread its benefits to all of society. Layal Jebran is one person who’s helping to make a difference.

Layal Jebran is the type of person who can give an interview on the phone while giving directions to her friends while walking through the streets of New York City looking for Thai food. She’s the type of person who can start multiple companies while traveling the world giving motivational speeches and accepting awards. To call the 29-year-old woman, a multitasker would be an understatement. In the startup world, she’s more like a superhero.

“I started as an activist when I was 12 years old,” Jebran said. “And my first startup happened my second year in college.”

That successful startup used the Internet to connect freelance advisers to clients who needed them in the Middle East, but like many entrepreneurs, Jebran didn’t stop there. Lyl Big Designs led to other projects, and she continued developing several different ideas Continue reading
