Brocade Communications Systems 4000 Hoja De Datos
The Brocade NetIron XMR Series is
designed from the ground up for high
performance and scalability to address
the needs of the most demanding
ISP, Internet data center, inter-Metro
connectivity, and multi-service operator
applications. All routers in the series
feature wire-speed, low latency, and low
jitter routing for IPv4, IPv6, MPLS, and
MPLS VPN services, and they support both
edge (PE) and core (P) router deployments.
For metropolitan area networks (MANs),
the NetIron XMR routers support high-
performance Layer 2 switching which allows
for cost efficient and seamless integration
with Layer 2 MANs or Layer 2 MAN access
layers without compromising performance.

Designed for high-end routing applications,
the Brocade NetIron XMR Series features
Brocade Direct Routing (BDR) technology
for full Forwarding Information Base (FIB)
programming in hardware, together with
hardware-based, wire-speed access control
lists (ACLs) and policy-based routing (PBR)
for robust, high performance IPv4, IPv6, and
Layer 3 VPN routing. Complementary to FDR
is a full suite of unicast and multicast routing
protocols for both IPv4 and IPv6. Supported
IPv4 protocols include RIP, OSPF, IS-IS, BGP4,
PIM-DM, PIM-SM/SSM, IGMP, BGP-MP
for multicast, and MSDP. Supported IPv6
protocols include RIPng, OSPFv3, IS-IS, BGP-
MP for IPv6 (BGP4+), PIM-SSM, and MLD.
Building on this solid routing architecture, the
NetIron XMR routers also provide dual-stack
IPv4/IPv6 wire-speed routing to facilitate
a seamless migration to IPv6 without
sacrificing performance.

A comprehensive set of path calculation
and signaling capabilities using OSPF-TE,
IS-IS-TE, RSVP-TE, CSPF, and LDP allows
the creation of both traffic engineered and
non-traffic engineered infrastructures.
Within either infrastructure, the NetIron XMR
Series supports IP over MPLS as well as
MPLS VPN applications. The NetIron XMR
Series supports all three popular MPLS VPN
services, Virtual Leased Line (VLL), LDP-
Based Virtual Private LAN Service (VPLS), and
BGP/MPLS VPN, on all ports at wire-speed.

In addition, the Brocade NetIron XMR Series
offers Multi-VRF Routing for environments
where virtual routing is needed without
the complexity of MPLS. Using Multi-VRF
Routing, backbone operators can create
multiple routing protocol instances that peer
with each other in completely virtualized
domains while sharing the same physical
routers and links. The NetIron XMR Series
is able to support overlapping IP address
spaces through complete separation of the
routing tables. Forwarding plane separation
is supported through the use of standard
802.1Q VLAN tags.

The Brocade NetIron XMR Series is also
designed for enabling the evolving multi-
service and triple-play infrastructures. Built
with an innovative view of Virtual Output
Queuing (VOQ) architectures, packet
buffering, and packet scheduling, the NetIron
XMR routers offer non-blocking packet
forwarding and large capabilities for handling
severe congestion scenarios. Built on that
superior foundation, the Brocade NetIron
XMR routers deliver a comprehensive suite of
QoS mechanisms to enable next-generation
architectures. Using the Brocade NetIron
XMR routers, operators can implement eight
distinct traffic classes of prioritization with
true performance guarantees. Operators can
implement those performance guarantees
by choosing from different packet scheduling
schemes and tweaking the associated
configurable parameters. Additionally, by
relying on DSCP Drop Precedence, operators
can take advantage of Weighted Random
Early Discard (WRED) for differentiated
packet dropping in case of congestion within
a given traffic class.

High availability, crucial to converged
networks, is ensured through a combination
of highly resilient hardware and software
design, and advanced failure detection
and traffic protection/restoration schemes.
The routers feature complete hardware
redundancy combined with resilient software
featuring hitless failover and hitless software
upgrades with OSPF and BGP graceful restart
for maximizing router uptime. The Multi-
Service IronWare operating system, powering
the NetIron XMR routers, offers advanced
capabilities for rapid detection and bypass of
link/node failures such as BFD, UDLD, MPLS
FRR, and Hot Standby paths.
