Citrix NetScaler Powers Over 100 Million Mobile Subscribers with Deployments in World’s Largest Operator Networks
Citrix today announced significant momentum in the adoption of its telco-grade NetScaler application delivery controller (ADC) platform within mobile core networks, including those of many of the world’s largest Tier-1 communications service providers. The 100-million subscriber milestone reflects Citrix success in addressing the urgent need for operators to manage the onslaught of data and video, while ensuring they can effectively navigate the transition to network functions virtualization (NFV).
The telco-grade NetScaler, which is available as a single, multi-tenant or NFV-ready virtual appliance, supports leading open source orchestration systems and a full complement of telco-centric features. Deployed both within and outside the core network, NetScaler enables SLA-supported cloud services in the world’s largest telco clouds, leveraging Citrix TriScale technology to deliver to operators the industry’s most flexible and scalable economics. Within the core, NetScaler ensures scalable, cost-effective delivery of data and control plane applications and is a key enabler for Citrix ByteMobile Adaptive Traffic Management deployments in the mobile Gi LAN. With telco-proven availability and cloud-proven deployment flexibility, NetScaler supports the scale, agility and integration requirements of virtual next generation networks.
“The ADC plays a critical and ubiquitous role within the NFV Infrastructure (NFVI), helping to ensure the carrier-grade performance of virtual network functions and preserving user experience,” said Graham Finnie, chief analyst, Heavy Reading. “As part of the business case for NFV, operators want to minimize the costs of NFVI components including ADCs, while retaining architectural flexibility through choice of form factor. They will be looking for an ADC that has proven performance at massive scale and which also supports specific telco functionality that network functions need.”
“Supporting both 3G and 4G networks with over 23 million subscribers from our mobile business, True faces exponential traffic growth,” said Dr. Viriya Upatising, Chief Technology Officer, True Corporation Plc. “We needed a high capacity, low latency, telco-grade ADC that would optimize the performance of True’s applications, scale to support additional subscribers and enhance the subscriber experience. We are extremely happy with the performance of NetScaler and the support we receive from the in-region Citrix sales, support and services team is excellent. Citrix enables us to deliver applications and services at the performance level our subscribers expect while leveraging the flexible NetScaler architecture and elastic cost structure to strengthen our plan for the future."
“Operators agree that service agility benefits are much more game-changing where cost (capex and opex) savings will be a by-product, as they move to virtualized next generation networks (vNGNs), which will employ cloud computing, NFV and software-defined networking (SDN) technologies,” said Glen Ragoonanan, principal analyst, Analysys Mason. “Citrix is a potential key player with high performance, scalable solutions in all these areas. Citrix NetScaler ADC is but one of its virtualized network function (VNF) solution offerings, to-date.”
Enabling a service-agile network
A truly service-agile network supports a business transformation that dramatically accelerates time-to-revenue for new services, giving operators the ability to better compete – and cooperate – with third party providers of end user services and applications. NetScaler has been architected to improve service agility by:
- Ensuring that ADC functionality can be integrated into an NFV network through support for multiple orchestration systems, including CloudStack, OpenStack and Alcatel-Lucent CloudBand, with a framework to support emerging orchestrators;
- Enabling the creation of an application delivery layer that can be shared across virtual functions, across data, control and application planes and even across enterprise services and IT cloud infrastructure;
- Having the ability to evolve to an NFV environment as an element of the NFV Infrastructure layer (NFVI);
- Eliminating as a bottleneck the availability of ADC resources needed to support the rapid instantiation and scaling of the virtual functions that enable new services.
Applying cloud-scale economics to the NFV transition
Economic flexibility is a cornerstone of the business case for NFV but practical constraints dictate that physical and virtual networks will coexist for some years to come. NetScaler is designed to bridge the gap between physical and virtual, enabling an elastic, just-in-time cost structure through:
- Consolidation of up to eighty virtual ADCs within a single physical appliance that can be further scaled to a commonly managed pool of hundreds virtual ADC instances – the basis for a common application delivery layer within the NFV infrastructure;
- Software license-enabled capacity growth, matching expense to traffic;
- Large-scale clustering of physical appliances into a single functional ADC, minimizing the problem of aborted capex investment;
- Feature, function and OAM equivalence across entire physical and virtual ADC portfolio.
“Mobile operators have entered what is likely to be a decade-long transition to NFV, driven by a need to deliver a wider array of network services more quickly with a flexible cost structure that matches that commercial speed and the corresponding unpredictable traffic patterns,” said Klaus Oestermann, group vice president and general manager, Cloud Networking at Citrix. “This transition period will be inherently difficult, as different portions of the network – even different portions of the core network – will be at different stages of virtualization. All the while, data and video traffic will continue its dizzying growth, competition between operators will intensify and the urgency to identify new sources of revenue will become even more pressing. With its expansive portfolio of virtual next generation network solutions, Citrix is in a unique position to help operators address these issues.”
