Citrix Advances ADC Portfolio Built for Virtual
Next Generation 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.”
