Marvell Introduces Multi-Service Fabric for Core Switches/Routers

Marvell introduced a multi-service fabric targeted at enterprise core switches and metro edge routers. Marvell's new two-chip architecture, which consists of a fabric access processor and a fabric switch element, is designed for extreme scalability in the number of ports it supports, enabling switching systems to expand up to thousands of Gigabit Ethernet ports. The Prestera multi-service fabric also features the ability to scale in port speeds, from Gigabit to 10 Gbps to 40 Gbps and beyond, without changes to the backplane, chassis design or fabric architecture. Marvell achieves this capability using Dune Networks' technology combined with its own 3.125Ghz SERDES technology.


Marvell's Prestera-FX multi-service fabric chipset also features per-flow queuing schemes, where hundreds of thousands of flows are policed, queued and scheduled separately, enabling broad SLA support. The Prestera-FX fabric access processor performs ingress and egress functions to the switching fabric and integrates the complete traffic management functionality and the scheduler. The fabric access processor seamlessly connects to the Marvell Prestera-EX and Prestera-MX packet processors, enabling the connection of Gigabit Ethernet and 10 Gigabit Ethernet.
