The Challenges
Multimedia needed to build a network that could be scaled to cover the entire country of Poland.
Additionally, Gigabit Ethernet was required, to provide the necessary throughput for video, high
definition video and data. In order to maintain the network, similar products needed to be
deployed in multiple locations, allowing the approved trial network to be extended across the
country with the minimal amount of effort.The network also had to be compatible with the
existing SDH backbone network that inter-connected all the cities. All this had to be achieved,
whilst also staying within a price limit that allowed Multimedia to return a profit on their
investment.
The Solution
To meet their requirements, Multimedia selected a solution based on multicast routing. Choosing
multicast routing, as opposed to unicast, lessened the total amount of traffic, whilst also simplifying
their equipment requirements. However, this meant that the routers selected had to be able to
use Internet Group Management Protocol (IGMP) and be capable of routing multicast packets
extremely well under high load conditions, whilst also maintaining excellent latency for the video
traffic.This was especially important for the HD television streams.
After evaluating a number of vendors, Multimedia selected two products from Allied Telesis - the
AT-9924T, a 24 copper port Gigabit Layer 3 switch, and the AT-9924SP switch, an SFP port version
that is compatible with a wide range of optical modules. A local System Integrator,Tritech
performed the installation and commissioning of the equipment.
With Gigabit Ethernet capability on every port, the highly-featured AT-9900 Series switches bring
performance and value to a variety of networks.Versatile and adaptable, AT-9900 series switches
are ideal for organizations whose bandwidth needs will grow and change with their business needs.
With a bullet-proof design for maximum service uptime, the AT-9900 series transport Ethernet-
based services quickly and accurately to the most critical destination - the end user.
