Your Design Should Be Usable!

Whatever you design , it should be usable first. Computer network design is not an exception.You are not designing a network to support one service only such as VPN or Internet.It should give enough functionality for today and future needs.

Your design should be usable today and the future !

It was so common to use TDM and Ethernet, IP or MPLS as a transport mechanism at the Access and Aggregation network and for the mobile backhaul. TDM is for the real time , delay , loss, jitter sensitive traffic, Ethernet is for the general data applications.

Building a TDM based network is good for real time applications but expensive at the same time. Thus if you will design a converge transport network, you need to understand your business requirements first.

Which services business want to offer ? What are the trends ?

Network Complexity

Network complexity plays a very important role during network design. Every network designer tries to find the simplest design.

Although there is no standard definition for the network complexity yet, there are many subjective definitions.

In today network designs decisions are taken based on an estimation of network complexity rather than absolute, solid answer.

If you are designing a network, probably you heard many times a KISS (Keep it simple and stupid) principle.

We said that during a network design you should follow this principle. As you will see in the later in the article ,if you want to have robust network you need some amount of  complexity.

Today I throw a new idea which we should use as a principle for the network design.

“SUCK” it is the abbreviation of “SO UNNECESSARY COMPLEXITY IS KEY”.

People refuse to have network complexity and believe that network complexity is bad. But this is wrong !

Every network needs complexity, network complexity is good !

Let me explain: Read more
