Starent Networks Brings Intelligence to the LTE Evolved Packet Core with its Suite of Advanced In-line Services

Allows Mobile Operators to Enhance Network Performance and Customer Experience
TEWKSBURY, Mass.--(Business Wire)--
Starent Networks, Corp. (Nasdaq: STAR), a leading provider of infrastructure
solutions that enable mobile operators to deliver multimedia services, today
announced its suite of intelligent In-line Services will be available for its
LTE evolved packet core (EPC) offering. Starent`s In-line Services help
operators improve the subscriber experience and the performance of the core
network. Based on a flexible architecture model, Starent`s EPC solutions
combined with its In-line Services, allow mobile operators to add new services
to meet ever-increasing subscriber demands, network security and optimization
requirements without deploying external servers or elements.

With mobile broadband, applications are becoming more sophisticated from
real-time latency sensitive services such as voice and video to larger bandwidth
gaming and rich media applications. Starent`s In-line Services for EPC are
designed with the flexibility to accommodate and optimize for this wide variety
of applications, providing mobile operators with a simple and economic way of
delivering intelligent services over their current 2G/3G, and in the future, 4G
networks.

"Mobile operators are expanding their portfolio of services to satisfy
subscribers and ensure competitive differentiation," said Ashraf Dahod,
president and chief executive officer of Starent Networks. "As more operators
evolve to 4G, network intelligence is critical for both service differentiation
and network optimization. Starent`s multimedia core networking solutions are
specifically designed to simply add intelligent services to existing core
elements to further improve network performance, reliability and cost control."

Starent`s current suite of in-line services includes:

* Enhanced content charging - deep-packet inspection (DPI) of all data traffic
provides an understanding of each session or subscriber transaction. Through
DPI, operators can implement detailed billing schemes based on each mobile
subscriber session or transaction.
* Content filtering - controls access to defined content enabling services such
as parental controls.
* Network-based traffic optimization - optimizes sessions or flows and provides
quality of service based on parameters such as volume, usage, time-of-day, and
traffic type, such as increasing or restricting bandwidth based on service per
user.
* Application detection and optimization - detects specific applications, such
as peer-to-peer, and allows the network to appropriately manage those
applications.
* Stateful firewall - provides a security layer application to detect and
prevent unsolicited network applications, Denial of Service (DOS) attacks and
efficient management of IP addressing through Network Address Translation (NAT)/
Port Address Translation (NAPT).

Traditionally, operators have deployed new services through large server
clusters combined with load balancers, or on special purpose equipment. This
approach makes networks more vulnerable to errors and introduces session latency
or delay as every session sequentially flows through equipment whether or not
the particular service is applied to the subscriber. This can result in higher
costs and more network complexity by requiring mobile carriers to provision
hardware and software for services their subscribers may not use.

Starent`s services are deployed "in-line" or integrated into the bearer plane at
the edge of the multimedia core network in the mobile gateway. By having
services deployed within the bearer plane, as opposed to requiring the session
to be off-loaded to external application servers, Starent`s In-Line Services
provides simpler manageability, a reduction in the number of `hops` required
within a transaction, fewer points of configuration, consolidated accounting and
billing and integrated policy enforcement - all which reduce costs and greatly
increase performance.

Mobile operators are utilizing Starent`s In-line Services worldwide in their
current 3G networks.

Starent will demonstrate In-line Service capabilities for its open LTE Evolved
Packet Core (EPC) at booth #4531 at CTIA Wireless 2009, April 1-3, 2009.
