The heart of this device is a new state of the art PowerPC networking processor which makes the RB1000 faster than any other MikroTik product. The IPsec encryption accelerator chip increases the IPsec performance in RouterOS several times. Our tests have shown that it can throughput up to 400000pps or 3.2Gbps total throughput! Two Compact Flash slots for webproxy cache, configuration backups of the User Manager database or The Dude server are also present. RB1000 includes RouterOS - the operating system, which turns this powerful system into a highly sophisticated router, firewall or bandwidth manager. The unstoppable power of RouterOS and RouterBOARD combined, we bring you the fastest MikroTik router yet. RouterBOARD 1000: PPC8547 1333MHz CPU, 512MB RAM (preinstalled inside SODIMM slot), 4x 1Gbit LAN, 2x CF slots. RouterOS Level 6, 1U rackmount case and power supply built-in (supports 110V and 220V)
