Dialogic is exhibiting at Connecting West Africa, taking place at the
Radisson Blu Hotel in Dakar, Senegal tomorrow and Wednesday 11th of June.
Jim Machi is the Vice
President of Product Management at Dialogic. Today he shares his views on Network Interconnect Chaos.
A while back, I spoke at the US Telecom
“Voice Innovation Summit”. I was placed in the part of the conference titled
“From POTS to Communication Free-For-all”. My point of view is that even though
yes, there are many, many, many, many, many, many, many, many different types
of IP Networks, it really doesn’t have to be a free-for-all. First of all,
connectivity is happening today, so it’s fine in a certain respect. But it can
clearly get better, and if you are running a business and need to connect from
one country to another, IPX is one such framework to stop the chaos.
This blog is not going to be a treatise on
IPX and if you want to learn more about it, please read our
whitepaper here.
What I spoke about is that because of
different types of signaling on IP networks (because of SIP variants for
instance) and because of different types of media for the IP networks
(different voice and video codecs), and that fact that the IP networks still
need to connect to the PSTN, you get into a need to translate all of these
things when crossing network boundaries. This is no different than before, and
why gateways exist. However, in the IP centric world, this is why Session
Border Controllers exist.
But carriers don’t want to run their
services over the public internet. There isn’t any control over the quality,
nor the security. So the IPX framework deals with this. It’s essentially a very
large private IP network. So if you are IPX enabled, then as you cross network
boundaries the signaling and media conversion is taken care of, and the
security as well. One can join and participate just as a pipe (called bilateral
transport), or be service aware and charge for minutes for instance (called
bilateral service transport) or be a multilateral service hub, which is where
the QoS and this differentiated, premium services can live.
I then gave some examples of different
networks and their needs when crossing boundaries, such as fixed networks to
mobile networks (even if both are IP), etc.
If one thinks of the IPX as a big “cloud”
then you can put IPX aware equipment in there that can accommodate transcoding,
etc. I gave an example of a live press conference demo we did at the past CTIA
– where we demonstrated mobile video conferencing on the Verizon network where
we had a few people on the LTE network in New Orleans, one on the 3G network in
Times Square, one on a WiFi network and one on a wired IP network, all with
differing endpoints. It worked. But imagine if we had tried this from different
countries! No way at this time. But if IPX was in place, it definitely could
have worked.
So in summary, if you don’t know about IPX
and want to learn more, go read something J But IPX is a mechanism that can
provide for internetworking with IP and legacy networks, can be a platform for
enabling value added offerings that enhance the user experience, and can be a
common platform for cost efficient optimal global routing of IP traffic. A way
to end pending chaos.
