SEATTLE -- February 20, 2013

F5 Networks, Inc. (NASDAQ:FFIV) today announced version 4.0 of the F5^®
Traffix^™ Signaling Delivery Controller^™ (SDC^™), the market’s most mature
Diameter routing, load balancing, and connectivity solution. F5’s Traffix SDC
solution helps service providers control and manage network signaling in LTE
networks and provides seamless connectivity between legacy home and roaming
networks with its Signaling System 7 (SS7) interworking function (IWF).

Since the product’s inception, F5’s Traffix SDC solution has been fully
compliant with IETF, 3GPP, and GSMA standards. SDC 4.0 provides enriched
functionality, including more efficient redundancy mechanisms that enable SDC
sites to achieve higher performance rates.

Other enhancements in Traffix SDC 4.0 include extended protocol support for
RADIUS, LDAP, and other legacy protocols; a new graphical user interface with
an improved dashboard; more network-wide, real-time analytics and statistics
that draw information from multi-SDC sites; support for new hardware
architecture; and higher performance.

“Since its acquisition of Traffix in February 2012, F5 has strengthened the
SDC global footprint,” said Diane Myers, Principal Analyst at Infonetics
Research. “The reliability of the SDC has encouraged operators to rely on and
understand the critical role that a Diameter solution plays in LTE networks,
and in providing connectivity to legacy networks. The expertise that F5
Diameter engineers have brought to the market is a strength the company has
been able to leverage in becoming a leading vendor in the market.”

“2012 was an exciting year as the Traffix SDC solution was deployed in more
than 25 sites among tier 1, tier 2, and IP Exchange (IPX) carriers worldwide.
This reflects that service providers understand the value of a Diameter
signaling solution to ensure network resilience, increase quality, and enhance
performance,” said Ben Volkow, VP of Product Development at F5. “Traffix began
the year by becoming part of the F5 organization, gaining both significant
financial backing and a stronger delivery and support structure to enhance our
technologically advanced product to customers. This latest release of the
Traffix SDC solution is another example of how our deep expertise in Diameter
enables our customers to benefit from much higher performance and lowers the
investment bar for LTE.”

Traffix SDC 4.0 Highlights

Highlights of Traffix SDC 4.0 offering are as follows:

  *The Interworking Function (IWF) of Diameter/ SS7 Mobile Application Part
    (MAP) enables LTE elements, interfaces, and protocols to seamlessly
    connect to legacy SS7 components, thereby delivering cost savings on the
    reuse of legacy elements. F5’s SS7 IWF includes the following
    capabilities:

       *IWF Mobility Management (MAP/Diameter interworking for S6a, S6d and
         S13 interfaces based on TS 29.305).
       *Roaming (MAP/Diameter roaming interworking for S6a and S6d based on
         IR.88).
       *Scaled redundancy for higher performance levels  when the Traffix SDC
         solution is deployed in Active/Active mode. This enhanced scaled
         redundancy leads to a higher performance rate.

  *Enhanced Element Management System (EMS) capabilities, including
    network-wide real-time analytics and statistics, which enables the receipt
    of deep granular information about signaling and subscriber-related
    activities. Operators benefit from a network-wide mesh comprehensive view
    as well as a detailed level of information across various points in time.

F5 solutions play a critical role in service provider networks as providers
transition from 2G/3G to 4G LTE all-IP infrastructures. F5 provides
intelligent and context-aware solutions that give service providers greater
application visibility, optimize service delivery, and secure their networks.
This leads to increased average revenue per use (ARPU) and reduced CapEx and
OpEx.

F5 solutions also enable service providers to optimize, scale, and simplify
their service architectures and monetize their layer 4–7 networks with new
revenue generating application services. With Traffix™ Diameter solutions
deployed in more than 100 locations, F5 and its 4G and Diameter expertise
provides significant benefits to customers around the world.
