Marvell has unleashed the Marvell Prestera DX4200 series of packet processors that the company said enable highly differentiated service-delivery solutions in the access and aggregation layers for a new generation of converged fixed and mobile networks. The device family is designed to accelerate service provisioning and improve the deployment and management of private and public wireless networks while maximising service and application monetisation. The series is being offered by the company as a solution to complex bandwidth management challenges and the exploding mobile data usage.

The eighth generation Prestera DX familyis being offered in a 28nm process. Incorporating an advanced SoC for converged wireless and wireline networking, DX4200-based systems enable the integration of multiple network elements into a single entity, thereby reducing infrastructure complexity and enabling better TCO with more active services enablement per watt, stated the firm. An innovative integration of multi-core ARM CPUs, a carrier grade traffic manager and a flexible IPv6 packet processing pipeline in the DX4200 enable dynamic software defined networking and advanced service virtualisation.

As organisations move to the software defined public and private clouds, the Prestera DX enables the graceful transition for advanced service delivery and application-driven resource management capabilities across virtualized environments. Furthermore, with the proliferation of trends such as Ethernet in mobile backhaul, new tunnelling and forwarding schemes in the cloud environments, and consumer managed IT markets, the Prestera DX enables campus and enterprise IT administrators to overcome increased security challenges in their own infrastructure, Marvell added.

The DX4200 supports a complete complement of converged service enablers such as CAPWAP, MPLS, VPLS, OAM, SPB and Bridge Port Extension, as well as timing and synchronisation support. An integrated InterLaken interface also enables the development of transport and circuit switched solutions while leveraging the service enabling paradigms of the DX4200. The integrated traffic manager offers hierarchical flow based quality of service and massive external buffering enabling tens of thousands of applications and users through unique queuing schemes that insure no variance in user experience across different access models.

Finally, embedded multi-core ARM v7 processors enable a variety of offload capabilities that can be used for real-time analytics, system or module topology management and any other software defined networking solutions with capabilities that extend well beyond OpenFlow 1.3.2.

A simple and efficient programming model enabled by Marvell's eBridging architecture reduces design complexity and system development schedules while accelerating network and service deployment. These features are coupled with line rate performance, highly flexible physical interfaces and a large set of standards-based networking capabilities, continued the company.

The Prestera DX 4200 will sample to lead customers in September 2013. Interested parties can contact their local Marvell representative for further details of the comprehensive system development kit (SDK) and related device collateral of the DX family of products.
