To meet exploding bandwidth demand, mobile operators are upgrading backhaul networks to packet-based technology. This transition brings a major challenge: maintaining synchronization, a mandatory requirement for mobile network stability and handset handoff. As Ethernet is an asynchronous technology, newer methods and standards have been introduced to implement synchronization over Ethernet. Namely, IEEE 1588v2 PTP is becoming the choice solution for synchronization distribution, as it uses an exchange of timestamp between master and slave devices, thus providing frequency, phase and time sync over the existing Ethernet infrastructure.

This paper proposes a deployment strategy for operators and carriers interested in PTP. More specifically, it presents the five deployment phases that lead to a fully functional and stable PTP-based synchronization network: network survey for real-world metric measurement; benchmarking of various solutions to identify the best one; configuration and turn-up of PTP pipes; synchronization performance monitoring; and troubleshooting of PTP and synchronization-related events.

As the expectations of mobile subscribers continue to rise, swift resolution of network issues is critical. To reduce customer churn, network operators must be able to quickly identify the source of network issues. To minimize OpEx, the results of network analysis must be available in real time. In light of this challenge, EXFO’s experts have produced the highly valuable white paper, How to Get a Detailed View of Your Subscribers’ QoE in Real Time, which investigates the options available for determining subscriber Quality of Experience—in the era of increasingly complex and evolving networks

In a converged multiplay world, service assurance becomes more important than ever before. With a nod towards Hokusai’s “Thirty-six Views of Mount Fuji”, this white paper describes three views of multiplay convergence (revenue, CAPEX and OPEX) and shows how a converged multiplay service assurance solution benefits all three.
