IP Wave
For Service Provider Networks

State of the Art IP andOptical Networking

Shift to a Services Driven Network

IP Wave Portfolio for Service Provider Networks

Multiple factors are driving the telecommunications industry to an inflection point.
•5G and fiber-to-the-premise buildouts are fueling massive increases in access and transport bandwidth.

•Users require increasingly sophisticated services with defined performance characteristics for cloud gaming,
telemedicine, symmetrical home working, and the social shift to an AR/VR metaverse.

•Cloud networking is moving from centralized data centers to compute and storage distributed across the network,
creating more complex high-bandwidth traffic patterns•

Competition is rising from new directions creating an urgency for services differentiation and agility. Webscale
content providers have begun competing for Internet and cloud connectivity services to businesses, independent
network operators are eroding the residential broadband customer base, and Utelcos are leveraging their fiber
plant for incremental revenues.

These changes are forcing service providers to rethink their approach to network architectures, moving from a transportoptimized to a services-driven approach.
Today’s networks focus on aggregating and backhauling traffic to a central core, with services mapped onto the traffic flows
using simple QoS parameters. While this approach manages costs, it takes an overly simplistic view of services. It does not
equip service providers with an ability to respond to an increasingly complex services and competitive environment. Worse,many complex services are engineered as an overlay using dedicated equipment, incurring even more expense.
Under a services-driven approach, the network is optimized for profitability, based on its ability to meet the performancerequirements of the services mix. This extends from service planning through the service control and dynamic
restoration processes, and the underlying resources these processes require.  Services dictate which network resources
are used, how they connect and the performance required from these connections. The network instantiates resources
and adapts connectivity dynamically to meet these needs. This enables service providers to adapt rapidly to changing
business strategies, customer mix, and service mix, without over-engineering their solutions.
Ribbon’s IP Wave enables service providers to move to this new dynamic services-driven approach, providing the services
agility required to lead the market, and the dynamic optimization required to increase profitability as services are deployed.

Optimized IP OpticalIP Wave solutions provides connectivity engineered to meet service performance requirements, using a complete IP
Optical product line that leverages best-of-breed merchant technology and focuses on delivering the right feature sets,
without over-engineering or overbuild.
IP Wave uses the Neptune IP routing portfolio to support increasingly complex services,an evolving service mix, and the dynamic edge cloud environment. Advanced IP routing
capabilities provide the dynamic, service oriented, metro connectivity required in thedistributed cloud era; and a super-converged multi-access edge allows multiple services
to be supported from a single, common, IP routing platform. With 400G ZR+ pluggables,
Neptune can operate in a single layer IP network using hop-by-hop provisioning, and ina multilayer IP Optical networks by using multilayer optimization to integrate with an
optical underlay. Neptune’s IP routing capabilities are built around a proven telco-grade
NOS allowing various hardware/software disaggregation options to be utilized.
IP Wave uses the Apollo IP optical networking portfolio to provide OTN transport and OTN switching solutions that scale
across access, metro and long haul applications. Apollo is programmable to 1.2T per channel, with an ability to transport
400G over the ultra-long haul; leveraging both capacity optimized transceivers and power-cost optimized 400GZR+
pluggable. Its open line system supports Ribbon and alien wavelengths on an equal basis, and enables service providers
to offer cutting edge shared spectrum services.
Using these elements, a critical question that IP Wave resolves is the debate between IPoDWDM versus IPoOTN. We
have concluded that it is both. IP Wave leverages SDN, IP routing, optical networking and control plane technologies
for both IP and Optical, to create a truly integrated IP Optical Network.  This network can be optimized to meet specificcustomer and service needs on a case-by-case basis. Sometimes this means integrating DWDM transmission
technologies directly into IP routers, and in others it means using an Optical Transport Network (OTN) layer to transport
IP services. Most large networks will incorporate both approaches.

Another area that IP Wave excels at is creating super-converged edge for consolidating mobile, residential and businessbroadband traffic. Our approach provides investment protection with the flexibility to support any access technology
and service, old, current, and new. Independent models show that IP Wave provides CapEx savings of 33%, OpEx savingsof 60%, and TCO savings of 46%, over five years compared to running separate edge networks. IP Wave also excels
at dynamically connecting the clouds, allowing network-as-a-service offerings as the webscale content and cloudnetworking environment evolves.
IP Wave networks are optimizable for each layer individually, but provide maximum advantage when used in multilayer
optimized configurations. Advanced planning algorithms design multilayer, any vendor, IP Optical networks that maximize
traffic handling with failure resiliency by looking holistically at all network layers, providing the best return on Capex.

As an example of Muse automation, Ribbon streamlined the MPLS service provisioning process for a tier 1 service
provider who was configuring several hundred links per day. This resulted in faster fulfillment, dramatically reduced
numbers of data errors and associated “do overs”, and increased the productivity, estimated by the customer to produce
up to 80% savings.

Open and DisaggregatedFreedom of choice, and no vendor lock-in, is a central pillar of IP Wave. At Ribbon, we believe network operators shouldbe able to assemble best of breed solutions, and take advantage of new technologies as they become available. IP Wavefully subscribes to this philosophy, providing future-proof protection.
IP Routing. A Telco grade NOS solution based on a widely deployed NOS provides IP routing features and capabilities
tailorable to meet all customer needs and network types. The NOS hardware approach supports multiple deployment
models – whitebox/greybox, pre-integrated, integration on request, and software only – and uses merchant chipset silicon to drive cost-effectiveness, simplicity and increase innovation deployment velocity. Open northboundinterfaces provide integration into any network controller including our Muse domain controller that provides acomplete set of NOS control capabilities.
Optical Networks. All optical networking NEs, covering optical transport, OTN switching, and ROADMs for wavelength
routing, are controllable independently through standards-defined OpenConfig and OpenROADM interfaces. Opticaltransmission based on OpenROADM O-FEC can interwork with other vendors’ optical transport product. Domaincontrol for an open optical line system, which supports both alien wavelengths and shared spectrum, can beexercised via a standard T-API interface.
Orchestration and Control: a cloud native open framework with open northbound APIs and southbound NE adapters,enables a multivendor, multilayer ecosystem, providing end-to-end services across the network. Service providers are
faster to revenues (fast provisioning), have improved quality of operations (automation), and avoid outages due toanalytics and preventative maintenance features.
