TIM Brasil Implements Oracle Session Border Controller as VNF For Increased Agility

TIM Brasil, the Brazilian subsidiary of Telecom Italia, has positioned itself as a leader in 4G and fixed ultra-broadband network markets, with more than 56 million customers and double-digit ARPU growth for this year. With a new brand signature of “Evolution never stops,” TIM is making infrastructure a strategic priority through investments in advanced IP networking technologies and IP services. A large part of its investments have focused on increasing SIP interconnect and peering capabilities with other Brazilian operators to help TIM expand its footprint for Internet, video, voice and cloud services throughout Brazil.

As it extends its reach, TIM needs to accommodate an ever-changing array of services and service deployment models, and needed the flexibility and agility to quickly expand and scale as needed. The operator sought a solution that would give it the flexibility to pick and choose different interconnect approaches in different markets while also ensuring security at its borders.

In that vein, TIM worked with long-time partner Oracle Communications on virtualizing the Oracle Communications Session Border Controller (OC-SBC), which it had for many years used for SIP trunking and peering. Through its NFV-based data center, TIM implemented the OC-SBC as a virtualized network function (VNF) running on an Oracle-supported bare metal hypervisor from VMWare® (ESXi). Multiple instances of the OC-SBC can now be clustered along with TIM’s existing purpose-built platforms, providing a way to gradually introduce “hybrid clusters,” which offer more deployment flexibility and network agility— and all without compromising the security, interoperability, and reliability of TIM’s purpose-built SBCs.

As a service provider in a market as large and dynamic as Brazil, the virtual SBC’s support of all commonly used IP communications enables TIM to peer with a wide range of service providers and to resolve multivendor interoperability and multiprotocol interworking issues. As a result, TIM has shortened innovation cycles and accelerated the introduction of services in competitive markets.

Because of the success of this virtualization effort —the SBC being the first virtualized element in TIM’s NFV-based data center—TIM plans to extend this software-based approach to other network functions.
