I fully believe and expect there are platforms where it would not be viable, especially 'l3 switch' type devices which make lot of assumptions to reduce cost. But I'd be surprised if high touch devices like ezchip, trio, solar (or what ever the huawei chip was called), fp3 etc. couldn't do it. Naively it feels like classify on ingress NPU, inject the classification information on cell headers over fabric, egress NPU then produces l2 rewrite information, taking into consideration the classification found on cell headers. -- ++ytti _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
