Carrier Ethernet OAM

Enterprise applications like telepresence, data center outsourcing, and cloud computing are pushing service providers to go beyond selling just connectivity or ‘dumb pipe’ to selling services. However in order to generate revenue, providers need cost effective solutions that support multiple services each having its own SLA. To meet the required level of service, the provider must honor certain OAM attributes for delay, jitter and packet loss. OAM (Operations, Administration and Maintenance) allows service providers to measure and verify the SLA to the customer. It also provides a means to efficiently…

What is HQoS and how is it different from QoS?

Carrier Ethernet networks today are migrating from being uni-service network (i.e., best effort) to being a multi-service network (prioritized). In order to run a multi-service network the carrier needs a mechanism that allows him to enforce QoS (Quality of Service) policies per user per service. HQoS (Hierarchical Quality of Service) allows the carrier to make sure each service gets the network resources it needs while coexisting on the same network infrastructure with other types of services. An additional value of HQoS is the ability to share unused network resources between different…

Mobile Backhaul Revolution

The mobile data surge, together with the LTE and LTE-Advance standards, represent many changes both in technology and in the business models and opportunities for operators and providers in this domain. The need for higher bandwidth is driving mobile providers to look for solution that will allow them to support it. Femto and pico cells are smaller base stations that have been designed to support smaller areas. They allow the mobile operator to offload the larger cell traffic and offer higher bandwidth in small location typically with higher population density.…
