Only cloud native virtualized network functions running within highly orchestrated container clusters can deliver on the promise of cost-effective, agile, elastic and resilient service infrastructures and applications. Metaswitch delivers the only complete VoLTE solution built from the ground up using cloud native microservices methodologies and deployable within public, private or hybrid cloud environments.
|Category||IMS and VoLTE|
|VNF Form Factor||VNFC, VNF|
Metaswitch is the first company to deliver a complete VoLTE solution built using cloud native software methodologies that can be deployed in public, private or hybrid cloud environments using lightweight Containers. Virtualizing the OS, rather than at the hardware level as with hypervisor approaches, dramatically reduces overheads, thereby enabling our individual virtualized network functions to instantiate immediately, providing both capacity on-demand and resiliency only when required.
|Top Use Cases||
|Customer Deployment Details||
Metaswitch virtualized VoLTE platforms, including our Rhino TAS, Clearwater Core IMS and Perimeta SBC, have been deployed in numerous global mobile operators, including AT&T, BT, Orange and Vodafone.
|Linux Foundation Projects||Cloud Native Computing Foundation, CORD, FD.IO, OPNFV and OpenECOMP|
|Supported Hypervisors||ESXi and KVM|
|Supported VIMs||OpenStack and VMware vRealize/vCAC/vCD|
While demanding a complete service infrastructure overhaul, VoLTE is table stakes for mobile network operators. Whereas the majority are looking to network functions virtualization to deliver a viable, cost effective and resilient, service offering, it is now clear that initial approaches to NFV, built on classic virtual machine (VM) constructs, cannot meet these requirements. Although VMs mask the inadequacies of legacy communications software components, which can be ported from proprietary hardware with little effort, these hypervisor-based environments have extremely high overheads and lack the speed to protect against infrastructure failures without costly redundancy that practically mirrors today’s non-virtualized implementations.
|Management Framework||Metaswitch is driving the development of automated deployment and life-cycle management of complex virtualized network functions by contributing our expertise across all open hierarchical orchestration ecosystems. Our VNFs can employ any VNF manager|
|HW Acceleration Supported||
As a company dedicated to delivering high performance control plane and data plane-centric virtualized network functions, Metaswitch has leveraged acceleration techniques, such as SR-IOV and DPDK and was an early contributor to FD.io.
|Performance and Scalability||
Metaswitch employs elastic scalability across all VNFs by leveraging a VNF software architecture based on stateless processing elements. A MANO layer monitors the load on VNF instances and dynamically adjusts the size of their population’s on-demand.
Metaswitch delivers carrier-grade reliability from an IT-grade cloud. We employ a combination of resiliency, redundancy and recovery mechanisms that handle faults at any layer in the stack, including hardware, operating system or application software
