Overcome Challenges at the Telco-Edge!

The emergence of generative AI, the shift towards enabling direct breakout to cloud services, the proliferation of IoT and other smart devices, and the growing demand for high performance from streaming and gaming services have significantly intensified the challenges associated with telco-edge cloud solutions. Let’s explore how building network like cloud can allow operators to overcome those challenges.

Overcome Challenges at the Telco-Edge!

Is Your Network Ready to Meet Workloads on the Edge?

As more and more latency-sensitive applications emerge – networking and compute functions need to move towards the network edge – closer to the end user. This trend also optimizes traffic distribution across the network as content-delivery networks become more distributed and content instances also reside at the network edge. The new network edge requires tight integration of edge computing and edge networking. This means that the network edge should be able to efficiently handle applications that require computing resources, as well as meet a growing volume of traffic.

Transforming the Network at the Edge

To make all this possible, services must “park” themselves at the edge. From an operational aspect, the edge will need to shape itself to host such services. Unlike the centralized core-out model, the edge doesn’t necessarily have what it takes for this in terms of real estate, power budget, management, and operational overhead, as well as a range of other small issues (ie, issues that are considered minor when aggregated in a centralized data center, but a huge burden once they are spread into hundreds or thousands of locations).

The metro-edge was designed to hold network elements located in the network PoPs and act as a high-capacity routing network node. Building out the telco-edge with a cloud-native approach will provide the infrastructure for any of the incoming edge services that are set out to overwhelm network edges with in-network compute resources. Such a setup eliminates any of the overhead that would be involved in building micro data centres in the numerous network PoPs.

A Disaggregated, Cloud-Native Infrastructure Model

DriveNets Network Cloud addresses these challenges by combining networking and compute resources over a shared, cloud-like infrastructure that allows operators to put greater functionality at the network edge, even in sites with space and power limitations. This allows network and cloud operators to improve their service quality, enable new, latency-sensitive services and optimize the traffic distribution across their network.

Scale Efficiently and Cost-effectively at the Edge

The DriveNets approach to the telco-edge makes edge computing and edge networking highly scalable and cost/space efficient, allowing efficient scaling of the control plane independently of the data plane to support extensive VPNs at the edge.

Operators can avoid monolithic router interdependencies and quality issues by disaggregating the control & data planes through optimized hardware and software for each networking plane.

This cloud-native architecture is future proof and based on open standards, with Open Compute Project (OCP) DDC-compliant hardware that leverages a microservice architecture.

Operators are Embracing Disaggregated, Cloud-Native Architectures

More and more operators are embracing disaggregated, cloud-native architectures as part of their next-generation network deployments. DriveNets was recognized as one of the industry’s leading vendors for the Disaggregated Distributed Backbone Routing (DDBR) solutions by the operator-driven Telecom Infra Project (TIP). KDDI, also the chair of the TIP Disaggregated Open Router (DOR) subgroup, announced in 2022, the first TIP DDBR-compliant deployment and the first disaggregated IP infrastructure to be deployed in Japan.

Also in 2022, AT&T announced the transition of more than 52% of its core network to a disaggregated whitebox solution powered by DriveNets software.  As the largest backbone network in the US, DriveNets Network Cloud software is running over multiple large clusters of white boxes in core locations of AT&T’s network. 

AT&T’s distributed disaggregated chassis (DDC) design, which was built on Broadcom’s powerful Jericho2 family of merchant chips, aims to define a standard set of configurable building blocks on less costly service-class routers ranging from a single-line card systems to large, disaggregated chassis clusters. 

Drivenets Network Cloud offers operators vendor diversity on all fronts, they can choose any ODM, Hardware, ASIC and Optics. Even the DriveNets network operation system can be replaced at any time without jeopardizing hardware investments. This flexibility enables operators to tailor their component choices for various edge locations based on their actual needs. 

Moving to the Edge

The deployment of an open, disaggregated cloud-native routing platforms coupled with open and efficient long haul 400G\800G optical transport platform, such as ZR+,  is exactly what large-scale operators require to manage the tsunami of demand that will be generated at the edge by services like 5G, fiber-based broadband, GenAI and entertainment content services, all while reducing the capex investment. 

A disaggregated, cloud-native model will allow operators to launch and manage services much more quickly especially at the latency-sensitive telco-edge.
