Allot Launches CellWise: Groundbreaking Mobile Broadband Traffic Management

CellWise Alleviates Cell Backhaul Congestion and Increases User Experience by Applying Policy Control on a per Cell Basis

BOSTON, Massachusetts, March 16, 2010 - Allot Communications Ltd. (www.allot.com/) (NASDAQ: ALLT), a
leader in IP service optimization and revenue generation solutions based on
Dynamic Actionable Recognition Technology (DART) (
www.allot.com/Dynamic_Actionable_Recognition_Technology.html),
announced today the launch of Allot CellWise (
www.allot.com/Cell_Wise.html#products), an innovative network service
that is designed to enable mobile broadband operators to manage traffic down
to the individual cell and alleviate backhaul congestion in real time by
providing intelligence about their network at the cell level. CellWise is
intended to manage costs and reduce customer churn by providing the operator
with precise network knowledge and control, and contribute to the overall
user experience by ensuring fair use per cell. CellWise is offered as an
integrated service with Allot's intelligent policy control and charging
solution included in the Allot Service Gateway (
www.allot.com/Service_Gateway_Sigma.html) platform.

"Cell congestion has traditionally been solved through heavy operator
investment in the backhaul," explains Andrei Elefant, Allot Communication's
Vice President of Product Management and Marketing. "Intelligent cell traffic
management from a centralized location is both a cost effective and time
efficient solution that enables operators to truly alleviate congestion on a
point by point basis."

CellWise, which works in conjunction with Allot's Subscriber and
Application awareness is part of Allot's multi-layered approach to
intelligent policy control and traffic management which together enable the
operator to decide exactly how the network's resources will be allocated.
CellWise continuously maps subscribers to cells in real time. Using dynamic
policy enforcement rules, the operator can define rules that will be enforced
when congestion occurs on a particular cell.

Allot Service Gateway Sigma (SG-Sigma) has 60Gbps of throughput and is
the only DPI-based Service Gateway platform designed to meet current and
future service provider requirements. It facilitates the fast and easy
introduction of new value-added network and subscriber services
(www.allot.com/Service_Protector.html), including TierManager, Quota
Manager, NetPolicy Provisioner MediaSwift, WebSafe and ServiceProtector -
services designed to reduce network TCO, increase ARPU and enhance the user
experience.

Allot CellWise is currently commercially available.
