Software defined networking able to controls varies brands driven snmp and it will be lead by central software management. Is it better compared to autonomic networking or the concept are equally identical.
I want to distinguish those two term: SDN and automatic computing. SDN enables flxible management and operation, which could be hard to be provided in the current network architecture where many numbers of control protocol for building a routing table and managing resource/access/mobility, so on. over the networks. But the automatic computing could be taken, enabling automated operation and management where some complicated computing jobs are required.
IMHO, Autonomic Computing is a concept and SDN is just one of the possible standard/technologies to materialize/manifest the concept of autonomic computing.
This is a rather confused question. Let's clarify it
Software Defined Networks (SDN) and Autonomic Computing (AC) cannot be compared. They are completely different things.
SDN is a way of abstracting the physical infrastructure of a network so that it can be generalized to be able to provide connectivity without having to get into the network elements themselves. In other words, SDN allows a network infrastructure to be able to behave in much the same way as a computing infrastructure does with an operating system and applications.
On the other hand AC is a concept where a system is able to parametise itself, and learn how to do this itself.
It turns out that SDN holds out the hope that networks can be made to exhibit some Autonomic behaviour.
SNMP is a whole different thing and cannot be put in this mix itself. It is a protocol for managing agents to connect with network elements. It is just nowhere similar to SDN or AC.
