Cortina IXF1024 24-Port 10/100/1000 Mbps Ethernet Media Access Controller Product Description The Cortina IXF1024 24-Port 10/100/1000 Mbps Ethernet Media Access Controller IXF1024 MAC is a highly integrated device that allows 2:1 oversubscription, which helps lower the cost per port. A SPI-4.2 system interface allows direct connection to network processors and forwarding engines. Advanced data path management techniques are used to funnel 24 Gigabits of bandwidth across a 10 Gbps system interface. This oversubscription of bandwidth is practical as client server networks rarely utilize full bandwidth at the network edge. To implement oversubscription, Cortina Systems, Inc. CortinaTM has included data path management functions such as rate limiting on a per port basis, priority queuing, IEEE compliant flow control, and programmable packet filtering. The device provides per port traffic statistics for performance monitoring, according to RMON RFC2819.
