The Switch has extended its multi-year partnership with Net Insight to build
100G network capacity across North America simultaneously integrated with
new cloud-based production and transmission service MIMiC...

or over a decade The Switch has
operated an extensive domestic
private fiber network built on Net
Insight Nimbra. This consists of more
than 50 primary nodes and a further
500+ connections into customer sites
at broadcasters and rights holders,
playout centers, major venues and
stadia.
To meet rising demand for more
flexible production and distribution
services, including remote
production, The Switch embarked
on a significant expansion of its
production network. Specifically, the
service provider wanted to create a
new 100Gbit fiber network, bringing
higher capacity
connectivity
to
key media and sports hubs in the
North American market. To further
facilitate evolving customer models,
The Switch launched MIMiC, an ondemand
cloud-based
quality
production
and
transmission service leveraging
the broadcast
redundancy
of its underlying fiber network with
the transmission powered by Net
Insight's Nimbra Edge.
Robert Szabo-Rowe, The Switch's
Senior Vice President of Engineering
and Product Management explains,
" Net
Insight's Nimbra equipment
has been at the center of our ability
to deliver seamless feeds to our
customers for many years. Nimbra is
our Swiss Army knife. It supports all
the main broadcast formats.
Most
Nimbra platform is
important, the
rock
solid and able to operate
the network at five 9s
reliability. It is
highly
resilient, extremely robust
and very deterministic which is
exactly what our customers need. "
In a significant expansion of its
network capacity, The Switch has
deployed 100Gbit connectivity once
again in partnership with Net Insight.
He adds, " Our network grows along
with the market and Net Insight is a
key part of our technology strategy. It
allows us to support a more diverse
range of production models
broadcasters,
that
enable
streaming
services, and other content providers
to be future-proofed in today's fastmoving
market. "
The MIMiC
Cloud
Transmission, powered
by Nimbra Edge, enables
sports
streaming services
other rightsholders to take
video feeds from anywhere in
the world and simultaneously
broadcasters,
and
deliver them to multiple - up to
hundreds - of destinations via the
internet, cloud networks and The
Switch's private network.
" We looked at a number of systems
and found that most
tend to be
based on one type of transmission
technology, usually SRT or Zixi, "
Szabo-Rowe says. " What
attracted
us to Nimbra Edge was its support
for multiple protocols. It is based
on RIST but has the advantage
of working with all standard ARQ
protocols to manage media over the
public internet. "
