The Service Provider Cloud
07.19.17

Software-defined networking (SDN) and Network Functions Virtualization (NFV) have revolutionized the traditional communication network architectures and have transformed the way communication service providers (CSPs) design their network infrastructure and services. SDN and NFV use standard virtualization technologies to virtualize entire classes of network functions that can be connected or chained together to create network services. The implementation of the Service Provider Cloud (Telco Cloud, Cable Cloud or Mobile Cloud architecture) is a strategic step for SPs to become competitive in the Digital Cohesion era.

 

A traditional telco service can be described as a set of solutions distributed over multiple domains. These domains, in turn, are supported by transport layers consisting of resources such as switches, routers, and firewalls. These resources perform complex and sophisticated interconnection functions in support of telco services. Functions often require multiple dedicated VPNs and VLANs, extensive load balancers, security, address translators, proxies, redundancy, latency control, policy-based routing, as well as carrier-grade QoS.

 

In traditional networks, transport layers are provided by dedicated site infrastructure incorporating purpose-built proprietary hardware. In the telco cloud and NFV environment, domains become a tenant of a federated cloud infrastructure where many transport layer functionalities can be replaced with VNFs.

 

The basic networking capabilities provided through VNFs can range in complexity from basic routing to multi-network routing and forwarding capabilities. Advanced capabilities include virtual private cloud (VPC), vBNG as well as carrier-grade NAT, vitual IMS, virtual evolved packed core (vEPC), virtual service control gateway (vSCG), GiLAN services, and DPI and traffic detection-steering function (DPT/TDSF).

 

The evolution of virtualization technologies, as well as the Central Office Re-Architected as a Datacenter (CORD) movement, have expanded the boundary of telco cloud beyond centralized data centers. Juniper’s end-to-end NFV solution offers a flexible architecture that fully addresses the unique idiosyncrasies of multi-dimensional deployment models. The path toward NFV and telco cloud will likely be an evolutionary approach. CSPs will retain existing infrastructures while expanding selected new network infrastructures based on virtual capabilities and deployment models.

 

This gradual approach minimizes the risk of network migration, empowering the CSPs to completely control the pace of network evolution without disrupting established operating environments, while achieving substantial network efficiency, operational flexibility, CapEx savings, as well as a faster time to market for new network services.

 

Juniper Networks has an unwavering commitment to innovative transformation. With our field-proven SDN and NFV end-to-end solution as well as our experience from deployments with global CSPs, Juniper has been a collaborative partner for unlocking market opportunities while driving sustainable long-term competitive advantages. We are the leaders that have helped CSPs complete the shift into IP platforms, and we will continue to facilitate their transformation journey into NFV and beyond.
