Introduction
10Gigabit Ethernet provides an ideal interface to meet bandwidth demands for today’s backplane applications, and single-chip switching solutions offer a cost-effective way to deliver that bandwidth. A 20-port 10GbE switch chip dramatically improves backplane density, while minimizing both cost and power consumption.
Backplane configurations ranging from ATCA and Micro TCA to various types of modular enterprise switches can take advantage of these silicon-based switching solutions. In particular, these solutions offer a straightforward way to meet the bandwidth demands of emerging video-delivery applications.
The 20-port Fujitsu MB8AA3020 switch chip supports such applications with full non-blocking 10GbE bandwidth as well as features that are particularly well suited to a mix of network traffic types. These features include congestion management and VLAN virtualization. Additionally, the chip incorporates serial 10Gigabit PHYs for each of its 20 ports. This paper describes the 20-port switch chip and gives an overview of implementation opportunities.
