Architecture and Key Components
Juniper Networks service-built M Series Multiservice Edge
Routers are deployed in the world's largest networks, delivering
advanced IP/MPLS edge routing services at scale and helping
service providers transform their businesses. Constructed with
clean separation between the control plane, forwarding plane
and services plane, the M Series support multiple services
without compromise on a single platform to maximize revenue
and minimize operational and capital costs. Services supported
include a broad array of VPNs, network-based security, real-time
voice and video, bandwidth on demand, rich multicast of premium
content, IPv6 services, granular accounting and much more. This
IP/MPLS edge routing service portfolio continues to grow with
every release of Junos OS, leveraging the tremendous flexibility
and performance headroom of the service-built architecture.
Applications
The versatile M Series routers can be deployed in both the service
provider environment and in high-end enterprise environments.

In service provider environments, the M Series is deployed
predominantly as a multiservice edge router but can also be
deployed in small and medium cores, peering, route reflector,
multicast, mobile and data center applications.

Large enterprises typically deploy M7i or M10i in a number of
different locations, including Internet gateway router, WAN router,
campus core router, regional backbone and data center.
Enhanced for the Edge
The versatile IP/MPLS M Series routers can be deployed at the
edge of provider networks, in small and medium cores, and in
peering, route reflector and data center applications. Recent M
Series innovations have dramatically expanded edge capabilities
by leveraging the highly programmable Internet Processor II
application-specific integrated circuit (ASIC) and the IP/MPLS-rich
Junos OS. M Series routers are now deployed and scaling services at
the edge of some of the world's largest production networks.
Consistent Services to All Customers
The M Series spans from over 7 to 320 Gbps of throughput,
including the M7i, M10i, M40e, M120 and M320 Multiservice
Edge Routers. The same scalable and production-hardened
Junos OS runs on all IP/MPLS M Series, making a consistent set
of capabilities available at all network locations regardless of
customer connection or serving area density.
Access-Agnostic with Leading Densities
With its broad interface portfolio, a single M Series router can
provide a single point of edge aggregation for thousands of
customers over any access type—including ATM, Frame Relay,
Ethernet and time-division multiplexing (TDM)–and at any
speed from DS0 up to OC-192/STM-64 and 10 Gigabit Ethernet.
Leveraging dense Ethernet and highly channelized interfaces, the
M Series boast leading densities.
Most Comprehensive VPN Portfolio
The M Series routers also support the industry's most
comprehensive VPN portfolio with the ability to simultaneously
run and scale Layer 2 virtual circuits, Layer 2 VPNs, Layer 2.5
Interworking VPNs, Layer 3 2547 VPNs, virtual private LAN service
(VPLS), IPsec, generic routing encapsulation (GRE), IP over IP and
other tunneling mechanisms—with no performance compromise.
This broad set of VPNs meets the needs of the widest possible
set of customers, maximizing the service provider's revenue while
minimizing required infrastructure. For example, a provider can use
Layer 3 VPNs to deliver an outsourced routing service and can also
use Layer 2 VPNs to provide a point-to-point ATM service over a
common IP/MPLS infrastructure.
