Introduction

Technological evolution does not stop, and telecommunications networks are at the forefront of this transformation. VIVO, one of the giants in the industry, is adopting innovative strategies to optimize its operations and improve the user experience. In this blog, we will explore the implementation of SRv6 uSID, a revolutionary approach, in Telefonica VIVO’s infrastructure. This relentless evolution drives the transformation of telecommunications networks, adopting innovative strategies to enhance services and operations with a focus on user experience.

What is Segment Routing over IPv6 (SRv6)

Segment Routing over IPv6 is a routing technology that promises to simplify network architecture while providing flexibility and efficiency. Unlike traditional methods, which rely on complex routing tables, Segment Routing over IPv6, also called SRv6, encodes the entire instruction state into the IPv6 packet header, making the fabric stateless. This helps achieve better scalability and hardware efficiency. SRv6 is built on top of IPv6, simplifying the protocol stack as MPLS is no longer required.

What is EVPN (Ethernet VPN)

EVPN, or Ethernet Virtual Private Network, is a network control plane protocol designed to provide layer 2 network connectivity over a shared network infrastructure. The main function of EVPN is to provide VPN (Virtual Private Network) services for Ethernet networks.

By combining EVPN with SRv6, you can create a solution that efficiently integrates Layer 3 routing with Layer 2 connectivity over the SRv6 infrastructure. SRv6 provides a segment-based forwarding method, which is useful for optimizing IP traffic routing. When combined with EVPN, which is capable of handling Layer 2 requirements, you get a comprehensive solution for networks that require both Layer 2 and Layer 3 service functionalities.

Benefits for Telefonica VIVO

Routing Efficiency: Reduces the complexity of routing tables, improving efficiency in data transmission. SRv6 enables a simpler and more scalable network architecture, using the concept of source routing. It removes state from the network and reduces network complexity, making it easier to deploy and manage.
