M7i Multiservice Edge Router
The M7i Multiservice Edge Router is Juniper Networks’ most
compact routing platform. It’s 3.5 inches (8.9 cm) in height and
supports 10+ Gbps throughput. The M7i is ideal as an IP/MPLS
provider edge router in small PoPs or as an enterprise routing
solution for Internet gateway or branch aggregation. With its
integrated Adaptive Services or Multiservices Module supporting
hardware-accelerated NAT, stateful firewall, IPsec, and Juniper
Flow accounting, it can be used as a campus border router or as
head office customer premise equipment. It supports either 2
fixed Fast Ethernet ports, 2 fixed Gigabit Ethernet ports, or 1 fixed
Gigabit Ethernet port via a Fixed Interface Card (FIC), as well
as supporting 4 ejector-enabled PICs. The M7i router supports
interface speeds of up to OC-12c/STM-4 and Gigabit Ethernet.
PICs are interchangeable between the M7i and M10i routers.

applications, the M120 is designed to facilitate service aggregation
for the multiplay needs of both service providers and enterprise
users. The M120 extends a cost-effective, Ethernet-optimized
infrastructure with 10-gigabit networking capabilities to the
network edge. Capable of supporting MPLS services at Layers
2 and 3, including Layer 3 VPNs, the M120 is designed to deliver
maximum redundancy and facilitate the transport of legacy Frame

Key Components
Key components of each M Series router are the Packet
Forwarding Engine (PFE) and the Routing Engine.
Forwarding Engine (PFE) and the Routing Engine.
• The PFE is a logical entity responsible for packet forwarding.
It physically consists of state-of-the-art ASICs such as the
I-Chip ASIC.
I-Chip ASIC.
• PICs provide a complete range of fiber optic and electrical
transmission interfaces to the network. For a listing of available
PICs, see the M Series PICs and FPCs datasheet.
PICs, see the M Series PICs and FPCs datasheet.
• Flexible PIC Concentrators house PICs and connect them to the
rest of the PFE. On the M320, FPCs parse, prioritize, and queue
the packets before forwarding them across the midplane to the
appropriate destination interface. On egress, FPCs prioritize, queue,
re-assemble, and forward packets out through the appropriate
port. Up to four PICs can be mixed and matched within a single
FPC slot, increasing configuration flexibility and network scalability,
while maximizing PoP efficiency. The FPC required depends on the
platform and on the PICs that are needed.

factor pluggable transceiver optics (ordered separately).
• On the M7i and M10i, the control/system/forwarding-engine
board performs route lookup and switching to the destination
FPC. It makes forwarding decisions, distributes data cells
throughout memory, processes exception and control packets,
monitors system components, and controls FPC resets.
The name for this component on the M7i/M10i is Compact
Forwarding Engine Board or recent Enhanced Compact
Forwarding Engine board.

• The M120 uses a distributed forwarding architecture which
separates the PFE in two components which are connected
through the midplane: the FPC (or compact FPC) and the
Forwarding Engine Board (FEB). FEBs provide route lookup
and forwarding functions from FPCs and cFPCs. FPCs and
cFPCs are located on the front of the chassis, and provide
power and management to the PICs. This design allows greater
level of forwarding engine resiliency and system availability by
supporting 1+1 fast failover and N:1 standby failover options.

• The M320 also uses a distributed architecture, where the PFE
is contained entirely within the FPC. The latest additions to the
M320 FPC family is the set of three Enhanced III FPCs. The new
E3 FPCs provide additional QoS support, increased next-hop
scaling and system performance gains. Route lookup and packet
processing occurs on the ingress PFE, and is then switched
across the Switch Interface Board (switching fabric) to the egress
PFE for final route lookup and packet processing. The feature-rich
programmable ASICs deliver a comprehensive, hardware-based
system for packet processing and support for uncompromising
