A home gateway network processor, described as the industry’s most integrated, has been introduced by Lantiq. The GRX350 combines outstanding routing performance and bi-directional packet classification to provide True Quality of Service (TrueQoS), along with a dedicated Trusted Execution Processor (TrustWorld) and hardware-enforced virtualisation (TrueVirtualization). 

This virtualisation isolates concurrent applications so that networking functionality executes separately from non-networking applications, such as smart home services. One benefit of this architecture is shortened test time and time-to-market of new applications, without affecting the stability and integrity of the core networking software.

The MIPS based GRX350 network processor integrates carrier grade edge router features into its advanced home gateway architecture, which includes multiple CPUs, Gigabit switch with integrated GPHYs, 3x3 WiFi, Voice and DECT telephony. Following Lantiq’s AnyWAN concept, the chipset handles any kind of WAN connectivity including the new G.fast standard.

Next-gen multi-service gateways based on the Lantiq processor will concurrently manage multiple Gigabits of incoming data streams from interfaces, like G.fast, GPON, Gigabit Ethernet WAN, VDSL2 or hybrid access network approaches such as DSLTE (DSL + LTE) .The GRX350 integrates advanced offloading technologies to intelligently manage the multi-millions of packets from all the wired and wireless devices competing for network bandwidth in digital home environments doing it with a 0% CPU load. In a first for home gateway network processors, Lantiq applies TrueQoS with hardware acceleration to all downstream and upstream data traffic, using full packet classification and bandwidth protection to assure the best possible customer experience. With the processor, the home gateway supports virtual provisioning of network functions in SDN/NFV scenarios by linking the standard OpenFlow protocol to its embedded TrueQoS and Packet Acceleration engines.

Rainer Spielberg, Vice President and Head of the Residential Gateway Solutions Business Line, Lantiq, commented: “The Lantiq GRX350 network processor opens the door to previously unavailable levels of service quality in broadband home networking. With Lantiq TrueQoS, customers get the service they want at the quality they want. In addition the GRX350 will power the most secure gateways ever available for home networks, thanks to the dedicated security core. We believe these unique features will be the heart of the true digital home.”

Based on Imagination Technologies’ interAptiv processor, the GRX350 includes multiple multi-threaded MIPS CPUs.

Samples are available now, volume production is planned for the second half of 2015.
