Insight into Telefonica’s Tecnopolis Project
We are very fortunate to be able to bring you this interview with Hector Menjivar, LATAM Sales Director for Telco Systems on the recent announcement that Telco Systems’ Ethernet demarcation and aggregation products were chosen by Telefonica Argentina.
Ethernut: Telco Systems just announced a high-profile project with Telefonica. Can you tell us more about it?
Menjivar: Telefonica Argentina was tasked by the Argentinean government to build the network for a new technology park in which the government could share developments in technology- and specifically communication technology – with the Argentinean people.
Telefonica was looking for a solution that could be used to carry multiple services – voice, video, surveillance, music, wireless (WiFi) and mobile on the same devices while giving each a different quality of service. Telefonica has been working with Telco Systems for years and they knew that our product could provide them with what they needed.
However, because of the nature of this project, we had to compete with some of the largest companies in the industry. We were selected not only because our solutions met their requirements, but also because they knew that they could rely on our technical support team to make sure that the deployment went smoothly.
Ethernut: So this not a one-shot win for you?
Menjivar: No, this is just another win in a list of projects in which Telefonica used both our demarcation and aggregation solutions.
Ethernut: Can you tell us more about the network?
Menjivar: Using a single fiber-based infrastructure, Telefónica designed an internal ring of five miles (eight kilometers) of optical fiber with 35 nodes that cover more than 200 points within the park to offer high-speed IP services. They selected the core devices from another vendor and then used our 10Gig aggregation switches (T5C-XG) to create non-blocking rings. Off these rings they connected our demarcation products (T-Marc) that can support over 120 separate services. Each service is configured with its own priority, jitter, delay and other QoS characteristics
Ethernut: How is it done?
Menjivar: Our software creates a Service Virtualization Layer in which all the services are controlled. In this layer we have Virtual Switching Instances (VSI) per service and virtual interfaces for incoming and outgoing traffic separately. These virtual instances are then assigned to physical ports but still managed separately. So while multiple services use same physical port, MAC addresses are learned per service and per virtual port. This service layer is fully compliant with MEF standards.
Our service management platform, EdgeGenie, further simplifies the ability to manage the services over the network.
