CompactPCI Ethernet boards switch IPv6 packets

CPX24 complies with PICMG2.16

Radstone Technology's PICMG2.16-compliant boards, pluggable into CompactPCI slots, will nicely support the emerging Internet IPv6 (Internet Protocol Version 6) definitions, with its 128-bit addressing scheme.

IPv6 is also anticipated to improve IPv4 in areas such as routing and network auto-configuration, and to support millions of new addresses. The protocol is expected to gradually replace today's IPv4, although the two versions will undoubtedly coexist during a long transition period.

The hardware
Dubbed the CPX24 line, there are air-cooled and conduction-cooled versions available. You can also order these boards at various levels of ruggedization. In operation, Radstone's 24-port Gigabit Ethernet boards will give you 88Gbps non-blocking switch-fabric full wirespeed performance. What's more, a store-and-forward architecture ensures low-latency switching, and an onboard MAC (media access control) table lets the boards automatically learn a network's connections.

Contributing to their sparkling performance are embedded Freescale PowerPC microprocessors clocking at 300MHz. They're backed up by 128MB of on-board SDRAM and 32MB of flash.

Network management
The CPX24s also offer network management features and capabilities. This includes support for IEEE-802.3ac VLAN Tagging (virtual local area network), IEEE-802.3ad Link Aggregation, IEEE-802.1S Spanning Tree, legacy IPv4 support, Traffic Policing, SNMP and Quality of Service.

As the company's press statement notes, the CPX24s include provision for optional fiber optics expansion. All 24 ports can be converted to optical outputs using transceivers that give you 24 ports of either 1000 Base-SX Ethernet or 1000 Base-LX, plus two ports of 10Gb XAUI Ethernet (either 10G Base-SR or 10G Base-LR).

Other features include built-in self test. This circuitry also lets CPX24s be linked with other Radstone boards to provide integrated system level health monitoring and diagnostics. Finally, these boards are configurable through Web interfaces.

The price for a 24-port copper version, built to ruggedization Level Four (conduction cooled) is about $8,000 in OEM quantities.
