With the introduction of 5G, Mobile Network Operators (MNOs) have the potential to become Universal Service
Providers, offering a complete range of telecom services to individuals, businesses, enterprises, and critical industries.
This requires a service-aware transport network that is able to dynamically link the 5G NR (new radio) network with
agile mobile core functionality. ECI’s Elastic Services Platform leverages a suite of modular software applications
over a programmable network infrastructure to deliver 5G connectivity dynamically, with the assured deterministic
behavior to make 5G services a reality.

DYNAMIC CONNECTIVITY
For MNOs to become universal service providers, they must move beyond the traditional mobile broadband services
to provide a full range of services to a wide range of customers and devices. 5G will usher in a new line of services,
based on the new capabilities of the 5G network - like ultra-reliable and ultra-low latency connectivity.
5G must also provide the communications network for a vast number of low-bandwidth IoT devices. These devices
range from the IoTs used to provide the massive-machine-type communications (mMTC) found in smart homes
and smart cities, to the IoTs used to provide the critical-machine-type communications (C-MTC) essential for
monitoring and actuation in modernized mission-critical control systems.

Each of these service types has its own distinct set of parameters and policies, and the 5G architecture uses an
approach called network slicing to partition the mobile network into multiple virtual networks. Each network
slice provides connectivity and quality of service, optimized to meet the transport requirements of the services it
transports.

ECI’s Elastic Services Platform makes network slicing a reality by providing the intelligence, agility, and autonomous
control necessary to take service requests and dynamically allocate the correct resources to the correct network slices.
It achieves this by combining the ECI Packet (Neptune) and Optical (Apollo) transport solutions with advanced
operations software from the MUSE™ software suite.
Neptune and Apollo provide a programmable network infrastructure that scales easily up to 100G, to the cell site
and beyond. They support full, seamless integration between the optical transport and the IP transport, providing a
fully-functional 5G connectivity fabric while maximizing cost efficiency.
The Elastic Service Platform takes this programmable network infrastructure and uses the agility provided by
Software Defined Networking (SDN) to deliver capacity and connectivity when and where it is required. The
flexibility provided by Network Function Virtualization (NFV) helps allocate virtual network functions (VNFs) to
enable the multi-access edge computing (MEC) needed, as for low-latency services.

DETERMINISTIC BEHAVIOR
Many of the new services anticipated for 5G are either
business critical or mission critical and require precise,
deterministic behavior with the network providing
guaranteed latency, reliability, and availability.
Unfortunately, IP/MPLS, traditionally used for IP
transport, optimizes dynamic connectivity at the cost
of determinism. But what are the options?
• RSVP-TE brings this determinism to IP/MPLS,
but it also adds complexity and just does not scale.
• MPLS-TP is the widely accepted approach of
deterministic transport for mission-critical services,
but achieves this determinism by sacrificing a
degree of dynamism.
Consequently, ECI introduced Elastic MPLS technology to allow customers to run both dynamic and deterministic
services in the same network, and even stitch between dynamic and deterministic service domains.

For the 5G connectivity fabric, the transport network needs to go the extra mile and offer dynamic connectivity with
configurable determinism – a concept ECI calls dynamic determinism.
To achieve dynamic determinism in the service layer, ECI added segment routing to its Elastic MPLS technology.
Segment routing is a source-based routing approach that takes the best assets of IP/MPLS and MPLS-TP to create
IP transport that is both dynamic and deterministic. When used in conjunction with a centralized path computation
element (PCE), deterministic service paths can be created autonomously and dynamically across the network.
To bring dynamic determinism to the network slices, ECI is introducing new technologies including Flexible Ethernet
and Elastic OTN.
End-to-end L2 and L3 VPNs

Elastic MPLS
Flexible Ethernet (FlexE) provides deterministic latency when multiplexing Ethernet, by adopting TDM principles
rather than packet buffers. In the TDM approach, client signals are allocated fixed timeslots in the transmission path.
Hence latency cannot vary. In addition, FlexE allows mapping of client rates to line rates without the need for flow
control or link aggregation.
ECI’s Elastic OTN combines traditional OTN switching with advanced optical techniques like Flexgrid, ODUflex,
and flexible OTN (FlexO), providing flexible, resilient, and deterministic optical transport.
The Elastic Services Platform uses the advanced operations software provided by MUSE™ Service and Network
applications to seamlessly integrate, manage, and control all of these IP and Optical technologies, providing the
dynamic determinism required by the 5G connectivity fabric.

ASSURED PERFORMANCE
The Elastic Services Platform provides the ability to deliver and assure enhanced VPN (VPN+) services across
the transport infrastructure. A path computation element (PCE) uses the service policies and parameters for each
service, plus knowledge of the underlay and overlay transport network, to calculate the path for each service. It then
incorporates strict path routing for deterministic services, or more liberal path routing for more dynamic services.
Segment routing maintains tight integration between the overlay VPN and the underlay network resources, using
segment identities (SIDs) to recognize the specific network resources used. This approach allows easy mapping of
services to the appropriate network slices.
Muse™ manages the entire lifecycle of the network slices and the services running across them by proactively
assuring that the services delivered across the connectivity fabric meet the service parameters and policies. Service
performance is monitored continuously, in real time, ensuring that service delivery always meets the defined the
service policies. This allows remedial actions to be initiated as soon as any service degradation is anticipated.
However, service performance can only be as good as the performance of the underlying network. Muse network
applications guarantee the efficiency and performance of the underlying network.
