Alcatel-Lucent 7750 SR | Data Sheet 3

routing applications, the 7750 SR

supports standards-based implemen-

tations of the full range of unicast and

multicast routing protocols: Border

Gateway Protocol (BGP-4), Inter-

mediate System-to-Intermediate

System (IS-IS), Open Shortest Path

First (OSPF) v3, Internet Group

Management Protocol (IGMP) v3

and Protocol Independent Multicast

— Sparse Mode (PIM-SM). The 7750 SR

uses the Alcatel-Lucent Service Router

Operating System (SR OS) image,

across all platforms, for operational

simplicity and in order to provide a

highly scalable software foundation

that is tightly integrated with the FP

technology architecture.

The Alcatel-Lucent 7750 SR fully sup-

ports a dual IPv4/IPv6 stack, allowing

for the simultaneous delivery of IPv4-

and IPv6-based services with no

performance impact. The dual stack

allows the operator to deliver IPv6-

based services on a per-customer basis,

negating the need to migrate the

entire network to IPv6. IPv6 support

includes IPv6 provider edge routing,

full multicast support and non-stop

routing on OSPF, IS-IS and BGP4,

enabling a number of applications,

including IPv6 provider edge (6VPE)

for IP VPNs, IPv6 Internet exchange

peering, and IPv6-based Internet

services. The comprehensive dual-stack

feature set is suitable for all major

application deployment types, which

include IPv4/v6 triple play, IPv4/v6

business VPN services and IPv4/v6

wireless broadband access/backhaul

beyond switched and routed services

network boundaries.

MPLS

Multiprotocol Label System (MPLS) is

ﬁeld proven, follows a highly consoli-

dated standardization process, and is

the key enabling technology for IP

network and service transformation —

for the aggregation, edge and core

network segments. Consistent with the

attributes of MPLS, the Alcatel-Lucent

7750 SR enables the full range of Layer 2

and Layer 3 protocols such as Ethernet,

Frame Relay, ATM, BGP-4, IS-IS and

PIM-SM to make it the platform

of choice for enabling network

convergence. The 7750 SR supports

the full range of the IEFT’s architec-

ture, stack, trafﬁc engineering (TE),

signaling, Pseudowire Emulation

Edge-to-edge (PWE3) and OAM

standards for service tunneling

ﬂexibility. The 7750 SR is capable

of delivering any combination of

services to any port, without a

tradeoff between throughput and

service depth. For operators moving

to an all-IP network, the 7750 SR

supports synchronous Ethernet

(Sync-E) for SONET/SDH-like synchroni-

zation performance to enable the

distribution of precision network

timing and synchronization over

Ethernet transport links.

High availability

The Alcatel-Lucent 7750 SR was

purpose-built from its inception to

guarantee the highest levels of

availability, resiliency and redundancy

from hardware and software architec-

tures. The 7750 SR is a fully redundant

platform with hot-swappable compo-

nents, including interface modules,

power supplies, and Switch Fabric/

Control Processor Module (SF/CPM),

with no single point of failure. In

addition to hitless in-service software

upgrades, MPLS TE graceful shutdown,

graceful restart — helper mode, fast

reroute and multichassis automatic

protection switching (APS) on SONET/

SDH links, the 7750 SR established an

industry benchmark with non-stop

routing, non-stop services and

multichassis Link Aggregation Group

(LAG). The industry-leading high-

availability features of the 7750 SR

have been validated by BT Exact, an

industry-recognized third-party test

organization. The 7750 SR maximizes

the quality of the user experience with

uninterrupted subscriber sessions, fully

enforceable stringent SLAs, and life line

services delivery.

Multi-service ﬂexibility

The Alcatel-Lucent 7750 SR leverages

the sophisticated FP technology to

deliver unmatched multi-service

ﬂexi bility and service-aware quality

of service (QoS) capabilities, with

the service depth that higher-margin

services require. The 7750 SR has a

highly scalable service-aware architec-

ture capable of providing simultaneous

support for triple play, mobile, Virtual

Private LAN Services (VPLS), Virtual

Private Wire Services (VPWS), PBB-

based services, enhanced Internet

services, and IP virtual private network

(VPN) services. It has the ﬁeld-proven

performance to scale BGP peers, routing

and forwarding tables, Layer 2 and

Layer 3 service instances, pseudowire

terminations, and service queues to

concurrently support the most deman-

ding consumer, business and mobile

services. The robustness of the 7750 SR

to converge multiple services over one

IP/MPLS network has been validated

in independent tests by Isocore, an

industry-recognized third-party test

organization.

Service-aware QoS provides service-

based queuing, policing and shaping,

with per-service bandwidth guarantees

to meet the most demanding SLAs.

For increased service differentiation,

the Alcatel-Lucent 7750 SR delivers

service-aware Hierarchical Quality of

Service (H-QoS) and accounting for

innovative service bundles. This helps

guarantee the performance of each

forwarding class in terms of band-

width, delay and jitter, while allow-

ing lower priority trafﬁc to burst when

higher priority applications go idle. To

ensure service continuity with legacy

services, the 7750 SR supports network

and service interworking using Ethernet,

Frame Relay, and ATM psuedowires

for advanced VPWS over the IP/MPLS

backbone.
