Juniper Networks and NEC build new network for Herotel to create South Africa’s first commercial network driven by Segment Routing.

Juniper Networks, a leader in secure, AI-driven networks and NEC Corporation, a leading global integrator of IT and network technologies, has announced that they have worked with Herotel, South Africa’s largest fixed wireless service provider, to enable the country’s first commercial network to deploy segment routing as part of a significant network upgrade initiative.

Herotel’s operational drivers for this innovation and investment include scalability and reach, agility, cost-effectiveness and the ability to consistently provide a superior user experience that can be tailored to regional requirements.

Since its foundation in 2014, Herotel’s overarching mission has been to drive ubiquitous, affordable internet connectivity and access to services and content across South Africa’s 1.22 million Km2, including communities in remote districts.

In addition to rapid organic growth of its network, the acquisition of numerous local service providers over a short period of time has further broadened Herotel’s reach. However, this approach has also led to a disparate, cost-inefficient infrastructure in need of simplification and alignment to meet its objectives.

Over the past year, this need has been exacerbated by significantly increased demand for secure, reliable connectivity and bandwidth during work-at-home and extended lock-down periods, with thousands of workers accessing corporate resources from ‘unknown’ home networks.

Furthermore, given the large distances between data centres and other points of presence, the ability to store and stream bandwidth-heavy content closer to as many customers as possible has become another imperative for Herotel.

Herotel chose to build its new IP network based on segment routing principles, augmenting traditional MPLS (multi-protocol label switching) techniques, to maximize operational flexibility and agility and to help deliver improved, consistent user experiences at scale and cost-effectively. Segment routing is a control-plane architecture which simplifies traffic engineering, enabling the path that data packets take across the network to be determined in advance. This means fewer network elements are involved, avoiding slow response to sudden network changes. It also supports the application QoS (Quality of Service), mapping specific applications and end users to preferential network service paths.
