Services PIC and DPC Features in the Junos OS

On routers equipped with one or more Adaptive Services PICs (both standalone and integrated versions) or Multiservices PICs or DPCs, the Junos OS provides the following services:

CoS—Traffic filtering based on class-of-service features. The Junos OS substantially supports the standards listed in Supported CoS Standards.
Dynamic flow capture—Tools for forwarding passively monitored traffic that matches filter criteria to one or more destinations. The Junos OS substantially supports the standards listed in Supported DTCP Standard.
Flow monitoring and discard accounting—Tools for sampling traffic, gathering detailed information about traffic flows, and performing discard accounting. On routers with one or more Monitoring Services PICs, Adaptive Services PICs, or Multiservices PICs or DPCs, the Junos OS substantially supports the standards listed in Supported Flow Monitoring and Discard Accounting Standards.
Intrusion detection services (IDS)—Tools for detecting, redirecting, and preventing certain kinds of network attack and intrusion.
IPsec—Tools for configuring manual or dynamic security associations (SAs) for encryption of data traffic.
The Canada and U.S. version of the Junos OS substantially supports the IPsec architecture, which provides a security suite for the IP version 4 (IPv4) and IP version 6 (IPv6) network layers for traffic destined to or originating at the Routing Engine. The Canada and U.S. version of the software also substantially supports Internet Key Exchange (IKE), which defines mechanisms for key generation and exchange, and manages security associations (SAs). The Junos OS supports manual and dynamic SAs. The Canada and U.S. version of the Junos OS substantially supports the standards listed in Supported IPsec and IKE Standards.
Layer 2 Tunneling Protocol (L2TP) client services—Services that enable support for tunneling Point-to-Point Protocol (PPP) traffic across a network. The Junos OS substantially supports the standards listed in Supported L2TP Standards.
Link services—System for providing multiple independent links between two systems. The Junos OS substantially supports the standards listed in Supported Link Services Standards.
Network Address Translation (NAT)—Security-enhancement procedure that hides the IP addresses of hosts on a private network by substituting publicly visible addresses for them. NAT services support Session Initiation Protocol (SIP) dialogs and UDP/IPv4 transport of SIP messages. The Junos OS substantially supports the standards listed in Supported NAT and SIP Standards.
Real-time performance monitoring (RPM)—Tools for configuring active probes to track and monitor traffic. The Junos OS substantially supports the standards listed in Supported RPM Standard.
Stateful firewall—Type of firewall filter that considers state information derived from previous communications and other applications when evaluating traffic. Stateful firewall services support SIP dialogs and UDP/IPv4 transport of SIP messages, and the Junos OS substantially supports RFC 3261, SIP: Session Initiation Protocol.
Tunnel services—Method for transmitting traffic along a secure path in a public network. The Junos OS substantially supports the tunneling standards listed in Supported GRE and IP-IP Interface Standards.
Voice services—Utility for transporting packetized voice traffic over an IP network infrastructure. The Junos OS substantially supports the standards listed in Supported Voice Services Standards.
