M-series Routing Platforms

Rich Packet Processing

A broad portfolio of services can be layered on top of VPNs for additional
revenue generation. A comprehensive suite of multicast capabilities, including
multicast over MPLS VPNs, enables efficient distribution of premium content.
Hardware-based IPv6 and a number of IPv6 migration tools such as IPv6 over
MPLS ease access to the benefits of this next-generation IP protocol without
performance compromise. NAT and stateful firewall can be configured per VRF
to enable network-based security for additional revenues and IPSec can be
used to support a premium security service for end users with high security
requirements. The M-series Service-Built Edge is continuously enhanced with
new packet processing capabilities to ensure maximum revenue generation
opportunities.

Highly Reliable

The M-series service-built architecture has been fundamentally constructed with
scale and stability in mind, including the modular and fault-protected design of
JUNOS software along with a rigorous system testing process. Furthermore, all
M-series routers offer redundant power and cooling and the M10i, M20, M40e,
M160, and M320 offer fully redundant hardware including redundant Routing

Engines and Switching/Forwarding Engine Boards. JUNOS software features
enhance this redundant architecture by enabling non-stop forwarding in the
event of a routing engine failure via a Hitless Switchover and when a minor
software upgrade is required by supporting In-service Software Upgrades. This
functionality augments other high availability capabilities that include graceful
protocol routing restart, MPLS fast reroute, VRRP, SONET APS, SDH MSP, BFD,
and LACP.

Robust Security

All M-series platforms support highly scalable J-Protect filtering capabilities,
unicast reverse path forwarding and high performance rate limiting for
industry-leading DOS attack protection. The J-Protect security capabilities of the
M-series platforms can be further enhanced with the Adaptive Services PIC that
accelerates, in hardware, additional network-based security services such as
high-speed NAT, stateful firewall with attack detection, and J-Flow accounting.
With the rich feature set of JUNOS software combined with industry-leading
ASIC technology, the M-series Service-built Edge provides a new level of reliable
and secure service delivery at the edge of service provider networks.
