DALLAS -- November 14, 2012

F5 Networks, Inc. (NASDAQ:FFIV) announced that its Traffix^™ Signaling
Delivery Controller^™ (SDC^™) is the market’s first Diameter solution to
support the new Diameter specifications per the latest release of RFC 6733 by
the Internet Engineering Task Force (IETF). The release of this new standard
makes the previous RFC 3588 and 5719 obsolete. Diameter is the base protocol
for Authentication, Authorization, and Accounting (AAA), enabling network
access and IP mobility in both home and roaming mobile LTE networks.

F5’s SDC product is the market-leading, multifunctional platform for Diameter
routing, load balancing, and gateway connectivity. Since the product’s
inception, it has been fully compliant with IETF, 3GPP, and GSMA standards. In
addition, all current deployments of the SDC are forward compatible with the
new standard.

“Through our work with communications service providers and global network
equipment providers, we are able to stay apprised of what’s on the horizon for
industry standards bodies,” said Ben Volkow, VP of Product Development at F5.
“We have been aware of RFC 6733 and welcome its arrival because it provides
for several enhancements for CSPs in the areas of security, management, and
flexibility. We see this leading to better routing and management capabilities
for operators to handle the challenges inherent with LTE.”

“The new IETF standard release RFC 6733 will be an asset to operators as it
adds flexibility in configuring their networks for the many situations and use
cases that LTE will bring—some of which we are already aware, and some which
we have yet to encounter,” said Dimitris Mavrakis, Principal Analyst at
Informa Telecoms & Media, a leading research firm. “F5 should be recognized
for its far-ranging vision into the LTE ecosystem, particularly around how
Diameter plays the enabling role for the success and profitability of
operators rolling out LTE technology.”

Some of the highlights of RFC 6733 are as follows:

  *Tighter security with better connections between peers by requiring the
    use of TLS/TCP and DTLS/SCTP
  *Added routing functionality and flexibility using routing table add-ons
  *Additional SCTP functionality
  *Updates to AVPs and messages to enable additional functionality and better
  *Caching mechanism to reduce signaling, increase performance, and enable
    additional routing capabilities
