Netrule - Introduction
► NetRule
runs on Java and therefore has the ability
to run on multiple platforms.
► Accuracy of Netrule results are compared with
those from spreadsheets, simulation tools, and the
actual network data showing accuracy comparable
to other techniques.
► Existing Networks can be imported.
► Built-in expertise about network components and
modeling, and can also import baseline data from
network management tools.
Netrule – Overview
► Interface
– User friendly.
► Left Panel – Hierarchical access to all the
network objects.
► Right panel – displays data (palette)
► Can Animate message flow , highlight
bottlenecks, shows utilization and delay bars
by component.
Netrule – Overview
Netrule - Overview
►
►
►
►
Basic constructs are
objects
16 different object types
3 object types relate to 7
layers of OSI
A network is divided into
subnets, used to define
logical groups, physical
locations or IP address
Netrule – Overview
A NetRule model consists of a set
of instances of these network
objects, and their relationships, as
shown on the following entityrelationship diagram
► Profiles: It concisely details
hardware (clients, servers, routers,
switches, hubs, firewalls, etc.) and
their capacity parameters through
profiles.
► Jobs: the exchange of traffic
between computers; a client
contains a job that generates
traffic (a message) and may
request tasks (work) to be
executed by a server and may
involve a reply of data
►
Netrule – Overview
►
Job Profile :- The size, rate, transport
protocol, and other details for these
messages are specified on a Job
Profile.
►
Links are defined by several network
elements, including an Interface, a
Filter, a Queue, a Class Policy, and a
Link Protocol.
►
NetRule imports your network
topology and traffic. By putting the
topology, discovered with a network
management tool, taken from a
database, or simply from a list,
NetRule can import your devices and
put them in your network.
►
Uses Graphics to display Results.

to allow user to select, place,
configure and validate NT devices.
Toolbar
Stencils
Overview
After you open a Visio drawing.
You may start the design process in two
ways: by using Visio VNE (Visio Network
Enterprise) stencils or by using one of
three Netformx stencils.
The devices you require for your network
design are dragged from the stencils into
the drawing page, where the project
topology is created and/or modified.
Overview
From the drawing page, you can:
Configure a device and its sub components manually
or by using configuration Wizard. Configured
devices can then be validated either manually or
automatically.
Generate and view a Bill of Materials sheet which
contains a list of the products and subcomponents
you have added to your network design, complete
with catalog number, vendor, category, quantity
and prices.
Change device views in the drawing from front to
rear or logical and vice versa.
Features
• Library Browser [Device Selection]
– Vendor-Classified
• Search Library [Device Selection]
– Vendor: All, Cisco, 3Com

devices.
– Configuration Wizard
If you are not sure which components to put into your device. The Configuration Wizard
allows you to specify the protocol and number of ports needed for your device and lets
you review and add components that meet your requirements.
Validation
– Auto Validate
Automatically verify the validity of each component as it is added to a device. If some
added component is not valid or more components are required, auto validate will take
you to the Validator page and walk you through the configuration process, addressing
all of the components needed for the device.
– Manual Validate
Performs a check on your current configuration and determines if it is valid. If not, it will
take you the Validator page to validate your device.
Validation Error Correction move from issue to issue, displaying error
messages and a list of components that will fix them by adding,
replacing or removing them from device.
