The SVI-SBC is a state-of-the-art, cloud enabled Session Border Controller providing comprehensive network edge security for fixed and mobile service providers and large enterprise customers.
SBC Virtualisation
The SVI-SBC session border controller is deployed in virtual environments worldwide enabling operators to benefit from the reduced costs and benefits that a cloud native component can deliver them.
The SVI-SBC can be enabled as a Virtual Machine (VM) on existing infrastructure or as a fully blown Virtual Network Function (VNF) in an AWS or Openstack cloud infrastructure.
Virtual Deployment
Virtual Machine on industry standard servers in a data centre using a hypervisor - i.e. VMware.
Cloud Deployment
Delivered as a Virtual Network Function (VNF) in AWS or OpenStack cloud infrastructure.
Auto Configuration
Open product management interfaces allows for auto-configuration by an orchestration platform. Whether orchestration is physically delivered via an XML, SQL, HTTP, TELNET etc interface, the SVI-SBC session border controller has been designed from the ground up to deliver remote operation, administration and maintenance (OA&M) control.
Distributed Architecture
The SVI-SBC is architected on micro-services principals separating the signalling and media planes into distinct software components.
The signalling plane provides a high availability core enabling centralised routing and control across the network.
Multiple media planes can be instantiated dynamically to meet bandwidth demands and / or distributed across different territories to match latency requirements and improve network resiliency.
Elasticity This architecture enables on-demand scaling in a virtual environment delivering full network elasticity.
Dynamic Load Balancing Dynamic load balancing insures optimum network performance with network load shared evenly across network components.
Network Resilience The distributed network architecture insures network resiliency coupled with high availability options as standard that insure carrier grade reliability.

IMS Support | A-SBC + I-SBC
The SVI-SBC provides next generation support for secure interconnect to IMS based networks. Delivering comprehensive VoLTE support allows the SVI-SBC to be deployed in the core of an IMS network or provide IPX / Roaming Hub interconnect.
The SVI-SBC provides a flexible architecture allowing providers to consolidate functionality and resources at both the access and interconnect interface through support for both the A-SBC and I-SBC modes.
A-SBC The Access-SBC sits on a service providers access borders, i.e enterprise locations, internet, 3G/4G mobile and fixed line.
Supports IMS functions:
P-CSCF: Proxy Call Session Control Function
E-CSCF: Emergency Call Session Control Function
BGCF: Breakout Gateway Control Function
AGW: Access Gateway
ATCF: Access Transfer Control Function
ATGW: Access Transfer Gateway
I-SBC The Interconnect-SBC sits on a service providers interconnect borders, i.e. the borders between service providers networks.
Supports IMS functions:
IBCF: Interconnect Border Control Function
IWF: Interworking Function
I-BGF / TrGW: Transition Gateway
