Challenges for the Modern Telco Cloud in the 5G and IoT Era

vcs 1

Deliver an Improved and Measurable Customer Experience

Next generation of applications will require measurable performance, and many will have stringent latency requirements. Automated vehicles, robotic surgery, drone navigation, mobile gaming, etc., will all place severe requirements on the next generation Telco Cloud infrastructure.

vcs 2

Meet Unpredictable Data Growth with On-demand Scalability

Data growth will be huge, but it will be unpredictable and will be in bursts requiring an adaptable and elastic framework that can handle the extreme demands that next generation of applications will place on it.

vcs 3

Achieve a Lower Total Cost of Ownership (TCO)

Lowering the TCO is also an expectation most CSPs share. With the programmability, abstraction and simplification that the next generation of cloud solutions promise, economies and efficiencies of scale and programmability are built into the business case.

vcs 4

Accelerate Innovation Cycles

The industry is already witnessing accelerated innovation cycles due to cloud-based automation through DevOps and this innovation is expected to continue with the next generation of Telco Cloud services. Service agility and faster time to market are considered table stakes.

VCS Telco Cloud Architecture

Nuage Networks VCS Telco Cloud architecture is based on Nuage Networks Virtualized Services Platform (VSP). VSP is the industry leading network automation platform enabling a complete range of SDN, SD-WAN, and cloud solutions. VSP provides advanced network automation across networks and clouds of all sizes and architectures from Telco Cloud data center private clouds to large enterprise wide area networks (WANs) to some of the largest public clouds in the world. VSP is the platform that enables Virtualized Cloud Services (VCS).

Virtualized Services Directory (VSD)

The Virtualized Services Directory (VSD) is a programmable policy and analytics engine. It provides a flexible and hierarchical network policy framework that enables IT administrators to define and enforce network resource policies in an intuitive and user-friendly manner.

VSD contains a multi-tenanted service directory that supports role-based administration of users, compute and network resources.

Virtual Routing & Switching (VRS)

Virtual Routing and Switching (VRS) is a software module that is installed in the hypervisor layer for VMs or as part of a container structure in virtualized server environments. It represents the virtual endpoint (i.e. VXLAN Tunnel Endpoint (VTEP)) used to create virtual connections to connect VMs and containers. VRS is based on the Open vSwitch (OVS) which is an open-source implementation of a distributed virtual multilayer switch which also provides the VTEP function.

VRS-B allows a bare metal server and its network function (e.g. WAN optimization, L7 firewall, load balancer, etc.) to participate in a given SD-WAN overlay VPN.

Accelerated Virtual Routing and Switching (AVRS)

The AVRS leverages Data Plane Development Kit (DPDK) technology to help improve packet performance by bypassing the Linux kernel.

Virtualized Service Controller (VSC)

The Virtualized Services Controller (VSC) is the industry’s most powerful and scalable SDN controller. It functions as the robust network control plane for datacenters, maintaining a full view of per-tenant network and service topologies.

Offload Virtual Routing and Switching (OVRS)

The OVRS leverages SmartNIC technology to offload SDN packet processing from the Linux kernel. VRS-G is the software gateway that allows the aggregation of bare metal applications through their VLAN IDs from their access ports.

VRS-G is the software gateway that allows the aggregation of bare metal functions through their VLAN IDs. VRS-G provides full VTEP capabilities thus allowing bare metal functions to be part of an SD-WAN overlay VPN concurrently with virtualized functions running on VMs and containers.

210 WBX

210 WBX is purpose-built to meet the demands of next generation data centers and cloud services, it is deployed as a scale-out underlay leaf or spine in the Clos-based data center architecture and is equipped with advanced IP routing and L2-L4 capabilities. It also serves as a powerful SDN VTEP to create Layer 2 and Layer 3 Virtual Private Network (VPN) services in the overlay. It also provides data plane aggregation of bare metal servers and appliances while providing a VTEP functionality between these legacy assets and other virtual endpoints in the network.
