Blue Coat PacketShaper

VISIBILITY AND OPTIMIZATION FOR NETWORKED TRAFFIC
Blue Coat PacketShaper is a cloud-connected network management appliance that combines on-box application discovery
with web content and web threat visibility powered by Blue Coat WebPulseTM. PacketShaper lets you measure network
application performance, categorize and manage web traffic based on its content, guaranteequality-of-service (QoS) for
preferred applications and content, and contain the impact of undesirable traffic.

Critical applications need to move at the
speed of business. With PacketShaper,

undesirable content that can raise legal
and compliance concerns.

-> Control the impact of acceptable (but
lower priority) web traffic on businesscritical applications.

FEATURES
MonitoringBefore you can optimize application
performance, you need an accurate
picture of network traffic. The
Monitoring Module, which delivers the
core functionality of PacketShaper,
automatically classifies and measures
network traffic by application and – in
the case of web traffic – by content
category. This unmatched visibility
into network traffic gives you the
insight of a probe but withfar more
sophistication. PacketShaper offers
application-intelligent Layer 7+ visibility
that integrates with WebPulse, the
collaborative defense providing realtime content categorization. In addition
to reporting on network and application
utilization and performance, the
Monitoring Module validates common
protocols and tracks what happens to
each connection established by anyapplication.
As the proportion of web-based traffic
continues to increase, PacketShaper
provides invaluable management of
web-connected applications such as
Facebook, YouTube, and WebEx. All
web content requested by users is
categorized under logical headings
such as Collaboration, Games, and
Social Networking. This latest advance
in web content control and web threat

Once traffic has beenidentified,
PacketShaper monitors performance
– over 100 stats per application class –
in real time. PacketShaper tracks the
bandwidth consumed by applications and
web content categories, the response
times of key applications by network
and server delay, and key stats like TCP
health, efficiency and retransmissions to
aid in troubleshooting. PacketShaper also
powers targeted packet tracesfor use
with protocol analysis tools.
Real-time performance metrics include
mean opinion score (MOS), jitter, delay,
and loss for voice and video conferencing
traffic over RTP. All these capabilities
can integrate into your performance
management environment, providing
intelligent thresholds and alerts when
problems are about to occur.
-> Identify and classify applications, webcontent, and web threats. Monitor
performance in real time and gather
the evidence you need to solve
performance issues.

Shaping
PacketShaper does more than just
monitor and measure. The Shaping
Module provides powerful QoS tools to
protect preferred applications and web
content categories while containing
the impact of undesirable traffic. With
PacketShaper, you can:
-> Guarantee bandwidthto latency-sensitive
applications such as voice, video
and VMware

With patented TCP rate control, the
Shaping Module can guarantee per-flow
bandwidth and automatically enforce
appropriate transfer rates for computers
at the far end of the network to deliver
bidirectional QoS.
-> Protect the best, contain the rest. Align
network content with your priorities by
