One Network or Residential and Business Services
Service providers that implement converged multiservice networkscan anticipate cost savings rom integrated network operations. The IPNGN Carrier Ethernet Design supports a smooth integration o business,esidential, wholesale and managed services over a converged inrastructure
by leveraging Ethernet and IP/MPLS technology.
Optimize Any-Play Services to the Home
IP customers, transitioning rom cable-based TV or circuit-switched voice,have high expectations o service reliability. Edge inrastructure mustaccommodate more advanced service requirements that surpass those orbest-eort, high-speed Internet services.
Bundled IP triple-play services require enhanced policy management, service control, an
granular quality o service (QoS) to meet subscriber expectations. Wireline providers are
beginning to implement any play networks that support integrated IPTV video, voice, Inte
access, and mobility as a single service package. Mobile service providers preer to deplo
third-generation (3G) and WiMAX services, Wi-Fi hotspots, and hot zones over a single sc
aggregation network that uses Carrier Ethernet or broadband wireless backhaul that will e
support higher-bandwidth Long Term Evolution (LTE) mobile services.
QoS, security, and resiliency requirements or these new residential services closely appro

across the network to successully support bundled residential services. Figure 2 shows h
Cisco IP NGN Carrier Ethernet Design provides fexible integration o any-play services.
This design extends consistent transport o any play services to a purpose built and
cost-eective Ethernet ber-to-the-x (FTTx) access solution complemented by validated support
or many broadband access technologies (e.g. Ethernet, DOCSIS, DSL, PON, WiMAX, WiFi).
Wholesale services are also supported or both residential and business customers whereby
retail service providers are given interconnectivity to their subscribers over a tunnel or virtual
private network (VPN). For managed services, the Cisco IP NGN Carrier Ethernet Design ully
integrates multiservice edge unctions into the aggregation network, thus optimizing the cost and
operational eort required or business VPNs.

Cisco VQE oers service providers the ollowing
benets:
Video error repair
Cisco VQE enables providers to precondition DSL lines or advanced video services such
by detecting and repairing packet loss on degraded copper lines. With this technology, a
box (STB) detecting packet loss can requests a retransmission while holding the video seq
in queue. The Cisco VQE technology automatically repairs the error by transmitting the m
packet, which is resequenced by the STB without interruption. The entire error repair cycle

Mobile wireless networks are poised to become a primary vehicle or a widevariety o telecom applications. Service providers are ocusing on buildingnetworks that can deliver a host o real-time multimedia solutions in additionto supporting business-class data applications and services.
Optimized Broadband Mobility
Mobile BackhaulMobile service providers need to build a robust yet fexible IP transport network that takes
advantage o packet economics. At the same time they must also support 2G, 3G, and em
4G technologies while continuing to align their network architecture with Third-Generation
Partnership Project (3GPP/3GPP2) standards. To achieve these goals, mobile service pro
must evolve their Radio Access Network (RAN) transport rom traditional circuit-based tec
to a packet-based solution.
The Cisco Mobile Transport over Pseudowires (MToP) solution uses industry-standard (PW
pseudowire and native Ethernet technology to extend the eatures and benets o the pack
based core into the RAN. The Cisco IP NGN Carrier Ethernet Design integrates the Cisco M
solution using circuit-emulation-over-packet (CEoP) shared port adapters (SPAs) that work
with traditional 2G and 3G radio equipment or IP R AN backhaul. These network capabilit
are combined with the integrated Cisco Content Services Gateway (CSG) modules to crea
dierentiated billing model through trac analysis, data mining, content ltering and intell
business policy enorcement. Mobile backhaul services to the cell site are complemente
by Cisco Mobile Wireless Router (MWR) series, supporting trouble-ree expansion to supp
emerging 4G technologies.
Mobile IP: WiMAXWiMAX is a ourth-generation (4G) wireless solution based on the IEEE 802.16e standard
delivering advanced broadband wireless services in emerging, high-growth and establish
markets. Service providers can take advantage o Mobile IP technologies to provide ubiqu
service and deliver a persistent connection or users, independent o their location. The C
IP NGN Carrier Ethernet Design supports integrated Broadband Wireless Gateway (BWG)

Industrys First Subscriber and
Application-Driven Solution
Personalized Subscriber and Application Management
As service providers transorm into experience providers, they must suciently control network
access in order to identiy, in real time, subscribers and the services they use. This access control
requires a clear understanding o who subscribers are, what services they are using, and what
policies govern each account.
The close coupling o subscriber- and application-aware unctions enabled by the CiscoIntelligent Services Gateway (ISG) and Cisco Service Control Engine (SCE) allows service
providers to dramatically enhance the QoE or any-play services. The integration o the Cisco
ISG and Cisco SCE into the IP NGN Carrier Ethernet Design enhances the user experience
and enables new push-based network eatures that are personalized, allowing subscribers to
select their preerred set o services or automatic prioritization based on individual needs and
preerences.
