Wireless backhaul QoS analyzed
New white paper from Tellabs.
A recent white paper from Tellabs notes that the growing demand for mobile data services is both a blessing and a challenge for wireless service providers. End-users, once content with simple voice and text messaging, are growing increasingly savvy -- they want the convenience of accessing the Internet and IP-based applications from mobile devices, without sacriﬁcing the Quality of Service (QoS) experienced on wired networks.
With the demand for IP-based services comes a dramatic increase in bandwidth requirements, best served by the transition to an Ethernet backhaul infrastructure. However, the need for the reliability, efﬁciency and timing functionality that TDM-based networks have historically provided remains. How can network engineers evolve the backhaul network while simultaneously supporting revenue-generating legacy services?
The white paper outlines a methodology to create a solid backhaul network foundation that addresses both current and future needs by examining the QoS parameters of the various services offered on wireless networks. By understanding how to prioritize network trafﬁc based on Class of Service (CoS), Tellabs contends that it is possible to right-size bandwidth allocation and correctly conﬁgure network elements for superior end-to-end connectivity that best meets the needs of customers and service providers.
