Technology is always evolving. However, in recent time, two significant changes have emerged in the world of networking. Firstly, the networking is moving to software that can run on commodity off-the-shelf hardware. Secondly, we are witnessing the introduction and use of many open source technologies, removing the barrier of entry for new product innovation and rapid market access.
Networking is the last bastion within IT to adopt the open source. Consequently, this has badly hit the networking industry in terms of slow speed of innovation and high costs. Every other element of IT has seen radical technology and cost model changes over the past 10 years. However, IP networking has not changed much since the mid-’90s.
