The Juniper Networks Adaptive Services II (AS II) PICs are modules that supply hardware acceleration for an array of packet processing intensive services in T-series and M-series routers. Today these services include stateful firewall, NAT, IPSec, cRTP, tunnel services, LNS (M7i only) and J-Flow accounting, with additional services being planned for future JUNOS releases. This wide array of services enables providers to secure their network infrastructure, to collect rich statistics for billing, capacity planning and security purposes, and to deliver new revenue-generating services all with a single module.
