Metro Market Segment:

The adoption of 10 Gigabit Ethernet in servers and enterprise backbones, along with the need for more bandwidth, pushes the Ethernet standard into Metro Area Networks. With its cost advantage, interoperability and easy migration to higher performance levels, 10 Gigabit Ethernet extends into the metro areas naturally.  Cortina Systems, Inc. offers a wide range of standards-based 10 Gigabit components that support both 10 Gigabit Ethernet and SONET/SDH, providing design flexibility and facilitating faster time-to-market for Metro Area Network infrastructures.  Cortina product lines offer solutions for Metro Aggregation and Metro Core applications. Metro Aggregation applications feature our high density GE solutions with enhanced QoS and oversubscription capabilities.  

Specifically Cortina products support:  

• High Performance Technology
  • Multi-port XFP and SFP interfaces with integrated SerDes eliminates extra serialization components and associated interfaces, which reduce cost and powe
  • Interlaken high speed inter-component connectivity technology along with XAUI and SPI-4 for high speed packet transfers between components
• Quality of Service (QoS)
  • Extensive QoS features with L2-L5 classification for triple play applications
  • Oversubscription capabilities with internal and external memory options enable more connectivity at lower cost points 

Target Applications:        

• Line cards for routers and switches, as well as ADMs, MSPP, and DWDM systems. Figure 1 illustrates a 40 Gbps router line card.

Relevant News:

• White Paper: Interlaken Technology: New-Generation Packet Interconnect Protocol: Serial link technology has multiplied device interconnect bandwidths in advanced communications equipment. Interlaken is an interconnect protocol optimized for high bandwidth and reliable packet transfers. It uses bundles of serial links to create a logical connection between components with multiple channels, backpressure capability, and data-integrity protection to boost the performance of communications equipment. This white paper gives an overview of Interlaken’s features and an implementation case study. This complete paper can be downloaded off the Cortina website at the following URL: http://www.cortina-systems.com/products/download/269
