ULASAN 1 - Network Convergence

NETWORK CONVERGENCE

My name is Luthfan Rasyad Maulana and this particular blog will be about Network Convergence explained in a video by Eli the Computer Guy with a duration of 46 minutes and 23 seconds. The link can be found -->

Network convergence is a huge issue in the modern world and could cause you major problems if you do now know what it is. Network convergence is where all types of technology systems are being changed and migrated so they they work on TCP/IP networks instead of their own dedicated infrastructure like cctv's and telephone systems using their own protocols like they used to. This can be a great thing but can face some problems. 

Back in the day everything used their own infrastructure. It used its own hardware and protocols. There were 4 silos which are cctv, telephones, PC, and access control. Everything had to have its own infrastructure with its own quirks and problems. Instead of having multiple different silos, network convergence converges all those silos into one. Separate types of cables are no longer needed and ethernet is now used for everything. In a lot of ways this is an amazing thing, you dont have to run multiple types of cables all over a building. One thing from a business stand point is that when you build out an infrastructure,  you always have to over-provision. The reason is the flexbility going in to the future and before convergence, it would have been much more of a hassle. All of these devices can now communicate with each other in new and interesting ways.

The things that have to be thought through with convergence are:

-Network capacity --> The speed of the network has to be able to account for the data being used by everyone using the network

-Service capacity --> More load can be weighted on the services being on this convergence and this has to be taken into account.

-Criticality of infrastructure: How critical an infrastructure can be

The problems with convergence are:

-Bandwidth issues --> if the network infrastructure is still the old one, and the amount of devices has multiplied by 4 of 5 times, you can shut down the network very fast even with simply 1 incorrectly configured device.

-Hacking issues --> with the old silos, even if someone hacks into one, they cannot reach the other silos, but now if everything is one on one infrastucture you can have problems with hacking.

-Compliance issues --> with boxed networks before convergence, communication was secure, but with convergence over one network, communication has to be ensure it is encrypted.

-Random issues --> Like overheating network cables. If a lot of power in run through ethernet, heat can start to form and overheat and cause accidents. 

Mitigating convergence issues:

-increase network/ ISP Capacity

-Qos

-Bandwidth Throtting

-Parallel Networks

-Pushing Intelligence to the Edge

I think that the more connected the world becomes, the more problems it faces. However, in my opinion, the benefits of a vastly connected world outweigh the problems and we should strive to achieve greater things without fearing the drawbacks. In this modern world something called the IoT(Internet of Things) has been forming and will lead to the ultimate converged world.
