SPA-Based Classification

Ethernet and ATM SPAs perform classification at the SPA level. In the SPA-based classification model, the
SPA performs both L2 and L3 classification, and decides on the priority of the packet. After classifying the
packets into high priority and low priority, the SPA has unique SPI4 channels per priority, and all the
high-priority packets are sent on separate SPI4 channels other than the low-priority SPI4 channel. In such a
scenario, the SPA queues the packets on high SPI4 channels to high-priority buffers and low-SPI4 channels
