Upgrading mobile backhaul architectures from legacy T1/E1 to Ethernet/IPThe rollout of new bandwidth-intensive applications is pushing service providers to actively seek cost-effective, reliable, IP/Ethernet-centric mobile backhaul solutions that can help them support future bandwidth requirements and subscriber growth, while securing long-term investments.
With the introduction of packet networks, key performance metrics are now more difficult to demonstrate, as service availability, transmission delay, link burstability and service integrity cannot be assessed precisely with a single ping command. For service providers of wireless backhaul, service level agreements (SLA) validation—using the right test and service assurance solutions—is becoming a crucial part of their efforts to optimize the quality of service (QoS) and the quality of experience (QoE) of wireless backhaul networks. |  |
