Cisco ASR1000 uses embedded linux, but also uses ASIC level special chip to archive line-rate processing, which Juniper and other vendors adapted long time ago. Performance will be varied how far you can tune the system for optimal performance. Alex Christian Meutes wrote: > Hi, > > --On Donnerstag, 19.
