I've understood HMC was better suited for IP lookup purposes technically. I think in PTX after they moved from HMC to HBM they also stopped doing lookup against HBM, and only used HBM for the delay buffer. I think also Cisco Silicon One originally intended to do lookups on HBM after the first 1M or so FIB, but somehow by the time they shipped it, no lookup against off-chip was materialised. -- ++ytti _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
