Course Description:

The Blue Coat WAN Acceleration Administrator (BCWAA) course is intended for IT
professionals who wish to master the WAN optimization fundamentals o
f the Blue Coat®
ProxySG®. After completing this course, you will understand:

Basic concepts of WAN optimization.

How to deploy and license the ProxySG.

Concepts of bandwidth management.

How WAN optimization works
and is configured on ProxyClient®.

Chapter Summaries

Chapter 1: Blue Coat Product Family

This chapter provides an overview of Blue Coat’s strategic vision of the Application Delivery
Network and how

Blue Coat’s hardware and software products work together
to enable
organizations to protect and enhance

network performance. Specifically, the ch
introduces the ProxySG®, PacketShaper®, ProxyAV™, and Blue

Coat Director. The chapter
also introduces Blue Coat Reporter, IntelligenceCenter®, PolicyCenter, ProxyClient™,


Chapter 2: Blue Coat Product Licensing

This chapter focuses on w
hat a customer must do to license their Blue Coat products and
what behavior they

should expect from their Blue Coat products in regards to the license. An
overview of the basic information that

each customer should know about the Blue Coat
licensing syste
m is provided. You will learn what types of

licenses Blue Coat offers, which
products have what type of license, and how each type of license is acquired.

you will learn what happens when the limitations of a license are exceeded and what

when a license expires.

Chapter 3: ProxySG Initial Setup

This chapter walks you through the steps you need to complete when setting up the
ProxySG for the first time.

Some of the concepts of initial configuration also apply to
reconfiguring an existin
g ProxySG or one that has been

restored to factory
default settings.


Chapter 4: Blue Coat Sky

This chapter introduces Blue Coat Sky, a streamlined management interface that offers
reports and configuration

options specifically applicable for enterprises w
here the ProxySG is
used primarily for WAN optimization. Topics

include Sky capabilities, how to switch between
Sky and the traditional Management Console interface, how to

avoid conflicts with the
Management Console, and how to update Sky.

Chapter 5: WAN
Optimization Features

IT managers work to achieve a complex goal: increasing efficiency, providing better control
and security, and

minimizing costs. Organizations can reach that goal by taking advantage of
Application Delivery Networks. The

chapter provid
es an overview of the key elements of how
ADNs support WAN optimization: bandwidth

management, protocol optimization, object
caching, byte caching, and compression.

Chapter 6: ADN Acceleration Deployments

This chapter discusses how an ADN uses byte caching

to reduce the amount of TCP traffic
across a WAN. The

ADN accomplishes this by replacing large chunks of repeated data with
small tokens representing that data. This

chapter also discusses the two
sided deployment
that an ADN requires, as well as the type
s of ADN deployments

that are supported by the

Chapter 7: Services

This chapter introduces the services framework of the ProxySG, which determines whether
specific traffic is

allowed or restricted through the ProxySG. It focuses on console service
and proxy services available through

the Management Console. The chapter also discusses
service ports, service port actions, and proxy service

attributes in detail.

Chapter 8: Configure ADN Roles

This chapter shows you how to configure a ProxySG to serve

in various roles in your ADN.
Any ProxySG can be

configured to be an ADN manager, branch peer, or concentrator peer,
based on its location in the network and

connectivity to servers.

Chapter 9: Monitoring Traffic

The ProxySG has many tools to help monitor

the traffic on your network. One of the most
important is the

Sessions display, which allows you to see what sessions are flowing through
the ProxySG. This chapter shows

you how to use the Sessions display, as well as some of
the other monitoring tools in

the ProxySG.

Chapter 10: Byte Caching

This chapter explains how byte caching optimizes an ADN by replacing large chunks of
repeated data with small

tokens representing that data. The chapter also discusses object
caching and when one type of caching is

eferred over another.

Chapter 11: Optimizing CIFS

The Common Internet File System (CIFS) is popular in enterprise networks because it allows
computers to share

files and printers. However, CIFS is inefficient over low
bandwidth links
or high
latency links,

such as those

typically found in enterprise branch offices. This chapter
explains how the ProxySG optimizes the CIFS protocol

through object caching and pipelining
and shows how the CIFS proxy can be used to prepopulate content on the

ProxySG for
d retrieval.

Chapter 12: MAPI Over ADN

Messaging Application Programming Interface (MAPI) is an RPC
based protocol used by
Microsoft Outlook to

communicate with Microsoft Exchange. It enables the optimization of
MAPI traffic between ProxySG appliances

at o
pposite ends of a WAN link. This chapter
explains how MAPI works and how organizations can use it to

accelerate e
mail across the

Chapter 13: Bandwidth Management

Bandwidth management, one of the key elements of an ADN, allows you to give users

access to resources while

limiting the total amount of bandwidth that they use. It also allows
you to set priorities for those resources. This

chapter explains how bandwidth management
works and how to implement it to improve network performance.

14: ProxyClient Acceleration

ProxyClient is Blue Coat’s solution for the ADN vision to extend application acceleration
capabilities to the

endpoints. ProxyClient provides acceleration by using CIFS protocol
optimization, CIFS object caching, and

n with ADN tunnels. The chapter
discusses the using ProxyClient for accelerated application delivery,

and as a solution for
remote users without a ProxySG.

Appendix A: Hierarchical Token Buckets

This appendix explains the bandwidth management scheme known as hierarchical token
buckets, which split

traffic according to category and prevent overuse in one category’s traffic
from affecting the performance of
