Ixia traffic generator manual pdf

Wednesday, December 5, Ixia Traffic Generator. Today's Internet is composed of thousands of networks and millions of users logging in at any given time.

At the same time, companies and their services are getting so large that the need to manage the increasing number of network terminals has become more than necessary for daily operations.

They need to have a reliable set of equipment that will be able to deliver results under immense pressure. Thus, such companies look for devices that have undergone rigorous testing, or they ensure that they test the equipment themselves. This is where the Ixia traffic generator steps in. It provides a complete platform of testing your network setup to ensure sustained and reliable performance. Why Is Testing Necessary?

The success of a business relies highly on the proper delivery of its services. It is therefore important that the equipment task to maintain or deliver the services to customers must not crash especially when beset when too many requests. A minor glitch due to network devices crashing will already cost a company millions that should could have used on something else.

In this line, Ixia traffic generator acts in the line of prevention of future issues rather cure them as it happens. Issues usually occur when a network is launched but has not undergone testing at all. What some companies do is to release a service or application to a certain number of users in order to figure out if the network can function in a real setting.

However, they run the risk of being seen by competitors or have a negative review spread due to connectivity issues. It will have its advantages, but releasing it to a select few will not be able to successfully simulate the sheer number of users that will be on the network.

The Ixia traffic generator takes care of checking if a network can withstand the load in a private manner. Another reason for testing is security. Several attacks have been carried out by malicious groups through an increased volume of attempts to use a particular application instead of exploiting vulnerabilities and holes in the code.

Such attacks have been used even popular websites such as Yahoo and Google. Unless the network hardware has been thoroughly tested, it will no doubt suffer the same fate as these established websites. They were able to get back up after several hours of severe slowdown at the dismay of their users.

Your company's network may even suffer worse if you do not employ a traffic generator. How Does It work? The traffic generators send thousands of dummy packets that are tagged with identifiers within the network.

These generators often perform benchmark tests listed by RFC , which is the accepted methodology of interconnected devices in a network. Tests can be two-way throughput tests on multiple ports with increasing sizes. Packet sizes start at 64 bytes up to 1. Then the loads are multiplied to reach millions of packets per second.

Best of all, the traffic generators are made to look like normal network equipment and can be placed side by side with your switches. Other Features of the Ixia Traffic Generator. UDFs output data may be masked with an arbitrary bit mask. The port supports a UDF that derives values from a table of offsets and values, by packet.

Supports Bit Error Rate Testing through the generation and verifications of patterns. Notes :. The connector type used on the card. The number of stream flows available on each port. The gap between streams, expressed as a range of time.

Size of the capture buffer. These load modules combine the advantages of the Xcellon architecture and provide the highest 40GE and GE port densities. Lava load modules can be used for testing layer 2 to layer 7 applications. IxVM is a software-based test platform that enables you to turn standard Linux Ethernet ports into virtual Ixia ports.

Then the loads are multiplied to reach millions of packets per second. For many years, packet generators verged on the capability of doing stateful traffic. These capabilities make it straightforward to test classification or queuing features in a switch or router.

Best of all, the traffic generators are made to look like normal network equipment and can be placed side by side with your switches. Copyright Spirent Communications, all rights reserved. Stateful generators are required grnerator testing devices or technologies that do not respond correctly to ixia traffic generator manual packets, and they add value to many other kinds of tests.

The address fields both MAC and IP addresses need to be easily modifiable so that ixia traffic generator manual packets traverse the network as expected. This enables users manal execute their own tests on the ports assigned traffiic them without disrupting tests being executed by other users on the system.

Some port scanners are ixia traffic generator manual of gathering additional information, such as the target operating system, using a method known as system trqffic. Network modeling tools are more easily set up than real test topologies and can allow alternatives to be more quickly compared and easily evaluated. About Affiliates Cisco Systems, Inc.
