What Does Convergence Mean?
Integrate and transport voice, fax, video and
data traffic on single, IP-based network
One structure, one architecture to support all
forms of information media on all forms of
network technology
Convergence is the term for combining personal
computers, telecommunications, and television
into a single user device
An integrated communications and IT
infrastructure, based on Internet Protocol (IP)
networking with guaranteed quality of service
(QoS)
Business combined with entertainment traffic
IP convergence refers to the integration and
transfer of voice, fax, video and data traffic on
a single, IP-based network.
Wired combined with wireless transmission
Convergence is all about merging voice and data
onto a single IP-based network
All information media on one network
Now, Ive got it. That was simple.
The coming together of two or more disparate
disciplines or technologies.
Convergence refers to the trend for some set of
technologies initially having distinct
functionalities to evolve to having those that
overlap.
