requires considerable experience with routers, hubs, bridges, and other net-

working devices. In particular, Lucent Technologies assumes that persons

installing, configuring, and managing the Access Point product have several

years of networking experience.

The Access Point QVPN Builder application lets you configure and manage

virtual private networks from a central management station. Builder is flexible

enough to provision the security profiles, firewall rules, and Quality of Service

policies for small or large VPNs.

VERVIEW

The Access Point QVPN Builder™ application (Builder) lets you manage

and monitor a virtual private network consisting of Access Point

™ sys-

tems (APs). This application lets you:

• Configure and create virtual private networks

• Configure QoS/Firewall parameters

• Configure NAT

• Monitor usage data

ACCESS POINT QVPN BUILDER APPLICATION

As use of the Internet for business-class applications continues to grow, so

has the importance of virtual private networks (VPNs). VPNs use a com-

bination of encryption, authentication, and tunneling techniques to create

secure pathways, or tunnels, between geographically separated hosts over

a public network infrastructure. Moreover, with the increasing flow of

data over costly infrastructure, bandwidth management and firewalling

capabilities are essential to classify and schedule IP traffic. Setting up

secure tunnels and managing bandwidth and firewalls to protect business

communications among widely dispersed sites can be time-consuming

and costly.

The Access Point QVPN Builder application is a powerful tool that lets

you create and deploy VPNs easily from a central management station.

While most VPNs must be configured on a host-by-host basis, Builder

enables VPNs to be defined at a single location and exported to defined

sets of hosts (Access Point systems) without network disruptions. Builder also

lets you incorporate firewall and Quality of Service (QoS) parameters as part

of a VPN definition, allowing you to rate-limit and shape traffic flowing over

tunnels. Thus, you get the benefits of IP QoS integrated within a remotely

managed tunnel framework, or QVPN.

INTEGRATED APPLICATIONS

The Builder includes integrated applications:

• The QVPN Request Config daemon allows APs to request (pull) their con-

figuration information from a Builder client or server.

• The Traffic Status application displays dynamic bandwidth usage informa-

tion with pie and bar graphs and tracks the performance of defined traffic

classes with a graph wizard.

• The Tunnel Status application has specialized applets that display sum-

mary information and traffic rate usage for the tunnels.

INSTALLING BUILDER

Before installing or using Builder, make sure the Access Point systems

(APs) are configured and reachable through SNMP. Otherwise, Builder

will not be able to configure these systems. You must configure the AP

with Access Point version 2.2.1 or later software beforehand (including

SNMP access and routing information) so that the Builder can connect to

each AP to perform its tasks.

The Builder has two versions — standalone and client/server.

The standalone version has these features:

• Installs on a single system

• Supports up to 250 QVPN nodes per VPN (VPN count is limited

by only disk space)

The client/server version has these features:

• Installs on a single server or many clients of the central server

• Supports up to 800 QVPN nodes per VPN (VPN count is limited

by only disk space)
