SDN/NFV Solutions
Existing network solutions are based on proprietary hardware appliances that slow down the service providers in rolling out new services due to the high procure-design-integrate-deploy cycle time compounded with additional investment costs, increasing energy costs and shorter hardware shelf life. The industry is betting on Network Function Virtualization (NFV) to find a solution to this age old problem. Over the past year Software Defined Networking (SDN) is gaining prominence which enables applications to have real-time visibility into the network and applications being able to program the network on-demand and thereby helping create application focussed infrastructure.
Going forward service providers are considering deployment of these solutions based on SDN/NFV that enables them with immediate revenue opportunities and makes their business more agile due to reduced CAPEX/OPEX, faster time to market, better resource utilization, flexible network management, and multi-tenancy support. However the transition to a virtualized environment using SDN and NFV has to happen in a phased manner with the need to co-exist with the current network solutions based on proprietary hardware appliances.
Currently Wipro’s SDN/NFV solution reference Framework comprise the following:-
Wipro Cloud Enabled Test Simulator (WIP-CETS)
Wipro vEPC
Wipro Cloud Enabled Test Simulator (WIP-CETS)
The Wipro CETS is a test framework to test VNFs and VNFMs in a real Telco cloud environment by generating all possible VNF life cycle events defined in ETSI NFV standards. CETS also supports NFVI platform readiness testing to host VNF workloads. This comprehensive test framework facilitates high level of test automation and addresses Telco’s concern for Performance, Orchestration, Elasticity, Resiliency, Service Continuity, and Energy Efficiency of Telco cloud deployments.
Business Benefits
Comprehensive NFV and SDN solution suites for reduced time to market of NFV/SDN roll outs
Easily customizable and flexible in adding new requirements from Equipment vendors/Telecom operator
Reduced time to market for Equipment vendors in offerings specific to Management/Orchestrator & Controller
Telecom operator benefits in VNF roll-out’s performance and functional stability in TELCO cloud environment
Supporting all the standard based interfaces as per ETSI and ONF
Software Solutions being optimized on TELCO cloud environment
Wipro’s CETS solution is developed using the Intel Servers with Xeon Processors supporting VT-x technologies.
Wipro vEPC
Existing Evolved Packet Core (EPC) network elements corresponding to MME, SGW, PGW etc are been traditionally deployed in various platforms using dedicated hardware for specific workloads within the core network. With increasing consumption of rich multimedia services, the need for an engaging customer experience and the emergence of new services such as voice over LTE (VoLTE) and M2M, Mobile Service Providers (MSPs) are seeking different technologies that could better address the dynamic and unpredictable nature of delivering mobile broadband services for consumers and businesses. The cloud computing and services industry was a logical choice to see if MSP’s business goals could be better served by using this technology. Mobile service providers (MSPs) have begun their journey to packet core virtualization to become more competitive in nature.
Wipro’s Virtualized EPC (vEPC) solution comprises of Virtualized Network Functions (VNFs) corresponding to the MME, SGW-CP, SGW-DP, PGW-CP and PGW-DP. It enables migration to the NFV framework and provides the following capabilities.
vSGW-DP and vPGW-DP data path acceleration using Intel DPDK and SR-IOV
vEPC VNF instantiation and de-instantiation based on control and data plane load
vEPC VNF redundancy, relocation and replication to handle failure scenarios
Integrated with Open source components (Openstack, Opendaylight) for management and orchestration
Coexistence with other non-virtualized EPC network elements and networks
Compliant with NFV requirements and specifications
The solution acts as a starting point and can be productized by NEPs to build carrier grade vEPC. It can also act as a Test simulator for testing LTE networks and for system engineering as well.
Business Benefits
vEPC reduces CAPEX/OPEX costs due to hardware consolidation and sharing of resources between operators
Improves network usage efficiency as vEPC network functions may scale independently according to their specific requirements
Ensures higher service availability and resiliency by replication and dynamic relocation of the vEPC network functions on failure
Allows creation of vEPC networks optimized for specific services based on geography/customer base
Allows faster deployment of newer services due to reduced procure-design-integrate-deploy cycle time
Wipro’s vEPC solution is based on the Intel Servers with Xeon Processors supporting VT-x, VT-d, DPDK and SR-IOV technologies.
