Media infrastructures, such as high-end media gateways and media
servers, are usually designed and implemented as customized
platforms. These infrastructures are the key underlying components
of the next-generation network (NGN). The customized architectural
design of such infrastructures is generally associated with high cost
and decreased flexibility for deploying and operating the NGN.
As multicore-processor computing-system technology continues to
improve, telecommunication infrastructures that make use of
commercial multicore information technology (IT) platforms are
becoming important topics for research. Although such
infrastructures provide flexible and extensible telecommunication
operation solutions at potentially low cost, such solutions must
address the computation and networking performance challenges
that result from commercial IT system architecture and system
software. In this paper, we study Voice over Internet Protocol (VoIP)
workloads, which are important for media infrastructures.
The VoIP traffic was benchmarked using multiple advanced
multicore platforms. We analyzed and evaluated the workload
behavior of the VoIP traffic, along with various computation and
network-accelerating technology.
