Keeping latency in check is critical for quality of service (QoS) of demanding Ethernet wireless backhaul, wholesale and business services. Given that Ethernet bandwidth is considered relatively ‘inexpensive’, some providers increase throughput to reduce latency and keep performance within strict SLA tolerances. However, the relationship between bandwidth and latency is anything but simple in packet-based networks, where increasing throughput can sometimes have no effect on delay, or even increase it under certain conditions. This paper explores the key sources of delay, and techniques to optimize latency without consuming excess bandwidth. These guidelines allow providers to use their network resources as efficiently as possible, while assuring the QoS of critical, real-time services. Download Full White Paper Here

By now there’s no doubt about it: mobile operators need to get their backhaul networks in condition to meet the burgeoning market for anytime, anywhere data access. Backhaul, once considered the humdrum side of an operator’s network, has become the topic du jour now that the mobile phone customershave shifted to smartphones and are taking advantage of data-hungry services in a big way. Earlier this month, AT&T reported that its wireless data traffic has grown more than 5,000 percent over the past three years, largely due to smartphones, which are used by about 40 percent of its post-paid customer base. All operators have to contend with this growth, and quickly: smartphones should represent the vast majority (65%) of phones sold in the country by 2012, according to Creative Strategies, an analyst firm. Operators are taking steps to prepare their networks to meet the expected demand, and the process of identifying specific backhaul needs and configuring the best solutions will force companies to bring the backhaul problem to the forefront of their infrastructure and business planning. This is a closer look at the available options and considerations operators must keep in mind as they prepare to build out this part of their networks.
