Software defined networking is advanced technology and if implemented it will be revolutionary.

I gather from the document that SDN will not replace IP network but will use in conjunction with IP for upgradation

SDN indeed frees us from learning numerous network protocols.

Did Huawei introduced the concept of SDN>

Softwarizing the network will make network prone to attacks and hack, i hope SDN caters and include protection

Is SDN just a concept or is it deployed already?

This document http://support.huawei.com/huawei ... iewthread&tid=75723 defines the migration steps.

Its good that all this information is formulated but imo it still needs to be studied further for seamless migration to total SDN architecture.

Very well implemented document

like it, good

Necessary information
