JUNOS Enterprise Routing

JUNOS Services

A JUNOS software service consists of a variety of Layer 2 and Layer 3 services, including:

• Multilink Point-to-Point Protocol (MLPPP)

• Multilink Frame Relay (MLFR)

• Compressed Real-Time Transport Protocol (CRTP)

• Multiclass MLPPP

• Stateful firewall

• NAT

• Intrusion detection service (IDS)

• IPSec

• Layer 2 Tunneling Protocol (L2TP)

• Active monitoring (cflowd)

• Tunnel services (Generic Routing Encapsulation [GRE], IP-IP, Physical Interface Module [PIM] register encapsulation)

• Data link switching (DLSw)

In an M-series router, enabling these services will require an additional piece of hardware: a Physical Interface Card (PIC) for packet processing. A J-series router supports most of the features in the preceding list and performs the packet processing within the software, so no additional hardware is necessary. Depending on the type of service required and the size of the service, different PICs can be used. The current offerings include:

Link Services PIC

Provides simultaneous support for three separate capabilities: enhanced multilink bundling, tunneling, and link fragmentation and interleaving (LFI)

Encryption Services PIC

Provides IPSec encryption for IPSec tunnels

Monitoring Services PIC

Provides J-Flow accounting at high speeds and across millions of flows, using standards-based cflowd v5 and v8 records

Tunnel Services PIC

Provides tunnel services such as GRE, IP-IP, IPv6 in IPv4, and multicast tunnels

Adaptive Services PIC (ASP)

Supports all services at Layer 2 and Layer 3
