Transforming transport networks

To stay profitable, operators must focus on new revenue-generatingservices while carefully controlling their cost structures. At the same time, new band-width-hungryservices, such as triple play and Ethernet virtual private networks (VPNs), are redefiining the underlyingtransport-infrastructurerequirements. These changes are driving the move fromcircuit-basedtransport, using TDM, topacket-basedtransport, using Ethernet in MANs and WANs.

Driven by end-userdemand for new services, operator network capacity is growing rapidly, with these networks transporting a wide variety of traffic. Operators all need to assess how their existing metro and core networks will accommodate trends and transitions in traffic patterns.

The new-servicesintroduction is probably the most critical factor to an operator’s success. The increasing demand for bandwidth to deliver new services is not reflected in comparable increases in revenue, presenting a signifiicant business challenge. TheAlcatel-Lucent1850TSS-100helps operators maximize their profiitability by transporting any service mix while keeping tight control on costs.


Multitechnology support with the 1850 tss-100

The 1850 TSS-100is a multiservice transport platform that supports any mix of traffic, fromall-circuittoall-packet.Its unique, technologyindependent universal matrix switches packets or circuits in their native format and transports them as they are, optimizing overall network efficiency and applicability. This capability allows operators to address transitioning fromTDM/circuit-basedtransport

to packet transport with the fexible provisioning of carrier Ethernet/transport, SONET, wavelength division multiplexing (WDM) and optical transport networks (OTNs).

The 1850 TSS-100supports current and future traffic requirements by eliminating the scalability issues encountered by traditional multiservice provisioning platform (MSPP)/ multiservice transport platform (MSTP) solutions. The 1850TSS-100is the ideal building block for evolving transport networks, allowing operators to fexibly split increasing traffic demands among any combination of carrier transport technologies.

The universal switch

The Alcatel-Lucent1850TSS-100offers operators a powerful tool for operatingfuture-safetransport networks, with total freedom in planning network resources to support the delivery of new broadband applications such as triple play, video, mobile and Ethernet business services. It also ensures seamless interworking with the legacy transport assets that support existing revenues, while fully addressing theoptical-packettransport convergence, as demanded by operators. This offers the following advantages:

Supports any mix of Ethernet, TDM, WDM, OTN and future services with only a simple change of interface cards, eliminating the need for future switch investments as new services or protocols emerge.

Offers a technology-independent universal switch, capable of switching packets or circuits in their native format and transporting them as they are, without costly mapping of circuits into packets or packets into circuits. The universal switch provides scalable switching capacity regardless of the traffic type.

Delivers technology-dependent line cards, packet, circuit or wavelength, where traffic is properly processed according to its native format. The line cards provide native traffic processing.

Eliminates, by innovatively demarking between traffic processing and traffic switching, the cost penalties traditional transport-node architectures incur with their technology-dependent processing performed in the switch (matrix). Packet and TDM traffic processing resides on the relevant line cards, allowing gradual investment to meet growing traffic requirements.

The concept of a single transport-aggregationplatform is a breakthrough in operator networking. Instead of

investing in several network layers to provide the required service mix, operators can now choose one platform

that delivers all services. By deploying the 1850 TSS-100as a unified transport platform supporting any mix of services, operators can:

Simplify network operations, significantly reducing operating expenditures (OPEX) and increasing the network fexibility and scalability

Lower the risk of capital expenditures (CAPEX) invest- ments that may vary over time, depending on servicedemand changes

Shorten time-to-revenuefor new services


Migrating to a packet transport network

Leveraging its universal, open architecture, the 1850 TSS-100allows operators to migrate their transport networks fromall-circuittoall-packet.It integrates a full set of SONET features to support traditionaltransport-networkarchitectures and to interwork with a large, existing installed base of equipment.

In addition, the platform supports transport packet switching, such as packet Operations, Administration, Maintenance and Provisioning (OAM&P), and integrated G.709 Optical Transport Hierarchy (OTH) trunk cards. The 1850 TSS-100provides acost-effectivesolution for implementing resilient metro and aggregation networks. This solution uniquely transitions from TDM/circuit to packet transport by smoothly migrating toward the delivery ofpacket-basedservices, maximizing return on investment over the network lifecycle.

The 1850 TSS offers Fast Ethernet (FE) and Gigabit Ethernet (GigE) interfaces for interconnecting with customer equipment or operator access equipment, delivering carrier-classcircuit and packet services. It also supports stacked unidirectionalpath-switchedrings (UPSRs) and bidirectionalline-switchedrings (BLSRs), with nonblocking aggregation and TDM traffic switching, or Layer 2 Switched Ethernet. These features offercost-effectivesolutions for implementing resilient metro and aggregation networks and switchedEthernet-to-Ethernet.

Combining circuit and packet interfaces and using Ethernet- based traffic management, the 1850 TSS-100 supports multiple Quality of Service (QoS) levels to provide a migration path toward the delivery of advanced packetbased services. It also ensures a smooth network evolution by enabling hybrid networks with totally fexible resource allocation between circuit and packet data services while fulfilling the roles of traditional MSPP/MSTP platforms.

Offering user-centricbroadband services

The 1850 TSS-100universal-transportplatform allows for next generation services:

Ethernet business services Ethernet-line (E-line) and Ethernet-LAN (E-LAN)

Triple play large-scaleEthernet aggregation

Mobile backhaul – Ethernet and TDM native support for mobilesecond-generationmobile system/thirdgeneration mobile system/Worldwide Interoperability for Microwave Access (2G/ 3G/WiMAX)

Carrier-to-carrierservices– packet/TDM/lambda (λ)

Mission-criticalservices– Government, research,

TV broadcasters, energy, utilities and transportation


Triple play over optical

Introducing triple-playservices establishes new broad-band-aggregationinfrastructure requirements for both scalability and the speed of service rollout. To meet these goals, many operators are introducing Ethernet into theirbroadband-accessinfrastructures. This allows network operators to progressively integrate theirtriple-playservices into a unified and homogeneous environment.

The 1850 TSS-100can efficiently provide distributed broadband service aggregation and transport toward the broadband service routers. It is a unified transport platform, offering fexible support when transitioning from legacy transport to Ethernet. The unified aggregation platform supports any multiservice business model and protects infrastructure investments.

When distributing video, it is important to broadcast these services from the last possible point in the network to avoid duplicating service costs inside the network. With a dedicated Ethernet network or a multiservice network, the multicast can be done efficiently at either the TDM or Ethernet level. The 1850 TSS-100can use a combination of distributed Layer 2 and TDM Switching, depending on the option that suits the provider’s requirements and minimizes costs (see Figure 2).

Supporting business services

Enterprises are increasing their use of high-bandwidthapplications and they are more frequently interconnecting LANs and data centers within a metro area. To address this market, operators need scalable,carrier-classsolutions that offer operators guaranteed QoS levels, support for differentiated SLAs and customer separation. Operators can build either dedicated Ethernet networks or multiservice networks able to provide other services through the same networking platform. The 1850TSS-100supports both of these models.

Wireless network traffic is increasing significantly with growth in subscriber usage and the introduction of new, wireless data services, such as video telephony, music, Internet surfiing and live television, along with video-on-demand(VoD).Price-basedcompetition makes profitable growth a challenge. Nevertheless, operators are forced to invest in new infrastructure to serve their customers’ needs. Should they expand with TDM technology for more capacity now and worry about strategically evolving to 3G andall-IPlater, or can they expand innovatively, making the network better now, while anticipating future requirements?

The 1850 TSS-100helps operators introduce new business services, either by leveraging the installed base, or by introducing a single platform to replace multiple traditional systems. In both instances, providing a fully fexible and reliable transport platform that meets today’s growth requirements for both EthernetandTDM-basedtraffic opens the door for a strategic move toward anIP-basedinfrastructure.


Network management

Operators need to focus on the service, rather than the technology, where it is used, how the network scales and how complex it is. By migrating from a technology-basednetwork management model to aservice-orientedone, the complexity of managing services is greatly reduced. AlcatelLucent offers two management platforms for operators, depending on their network requirements and planned evolution: theAlcatel-Lucent1350 Open Media Suite (OMS) and theAlcatel-Lucent

1340 Integrated Network Controller (INC).

The 1350 OMS management suite eliminates the need to deploy multitechnology element and network management systems, reducing CAPEX and OPEX. It offers a highly modular architecture to properly match operator requirements. It also:

Simplifies presentation of a multitechnology network to the user

Delivers future-safe,scalable platform that can be extended as the network and its services grow

Offers single point-of-alarm collection, with all network management information available on a single platform with a single login procedure

The 1340 INC is a leading-edge,single-platformnetwork management system for bothAlcatel-Lucenttransport networks and multivendor environments. Capable of supportingnext-generationand legacy equipment, the 1340 INC makes the transport network transparent to operators through a simplifiedview from a single Graphical User Interface (GUI). It also:

Provides end-to-endcircuit, fault and performance management

Extensively reports data, including card inventory, usage, utilization and historical reports

Simplifies operations with a single GUI for SONET, Ethernet, MSPP, ATM/Frame Relay, data circuit synchronous (DCS) and optical devices
