Implementing Voice over AAL2 on a Network Processor

Publisher Summary The flexibility and programmability of next-generation network-processing units (NPU) make them a key component of next-generation telecommunications equipment. NPUs can support a variety of packet-processing applications, with a variety of different requirements. This chapter discusses the special requirements and challenges presented by the Voice over AAL2 (VoAAL2) application. The architecture and design of a VoAAL2 application developed for the Intel IXP2400 processor is described, and the features of an NPU that are required to support this type of application are discussed. With strict quality of service requirements and asynchronous inputs, VoAAL2 can be performed on an NPU. The application is most naturally implemented using an asynchronous programming model. It is found that the IXP2400 naturally supports such a programming model. Support for asynchronous components that span microengines can be improved by adding support for a distributed lock manager.

Intel Corporation—Intel IXP2400 Network Processor: A Second-Generation Intel NPU

Publisher Summary Next generation access and edge equipment requires flexible programming, high performance, low power consumption, and small real estate. In context to this, Intel has developed a next-generation network processor, the IXP2400, which is optimized to meet these requirements. The Intel IXP2400 network processor delivers a new level of intelligence and performance for access and edge applications, enabling the realization of quality of service (QoS), enforcement of service-level agreements (SLAs), and traffic engineering at OC-48/2 .5 Gbps and 4 Gbps data rates. The flexible media interface allows a variety of media devices, ranging from OC3 to OC48 speeds to be connected without logic to the IXP2400 for easier design and lower system cost. These capabilities essentially allow OEMs and service providers to offer differentiated and tiered services to their customers while efficiently managing their network resources and bandwidth. The performance and flexibility of the IXP2400 makes it desirable for a wide variety of high-performance applications such as multiservice switches, DSLAMs (DSL access multiplexers), CMTS (cable modem termination system) equipment, 2.5G and 3G wireless infrastructure, and layer 4-7 switches.

Intel Atom C2000 Processor Family: Power-Efficient Datacenter Processing

The Intel Atom C2000 Microserver, codenamed Avoton and Rangeley, is a complete server and embedded processor system on chip (SoC) that provides up to seven times greater performance and six times the energy efficiency versus the prior-generation processor. Leveraging the Atom Silvermont microarchitecture, Intels 22-nm tri-gate manufacturing process and a robust set of integrated I/O, Intel is expanding its reach into datacenter computing.
