Overview NetChannel is easy–to-use network simulation solution that creates a virtual network environment in your lab mimicking production network environment. It provides a powerful, flexible and easy way to test the performance of your application under a real life network realities and enabling you to get a measure of application performance and real world end user experience. Application can be optimized for end user experience and many of the production environment issues may be resolved before application is rolled into production.

Features NetChannel is extremely easy to use, flexible and very powerful. Several network tunnels may be created on one net channel box. Network tunnel end points can be created based on IP address, port, protocol, or literally any bit of the IP datagram. Can emulate network characteristics

Bandwidth Constraints NetChannel allow you to configure the bandwidth constraints in following units: Kilobits per sec (kbps) Megabits per second (mbps).

Network Latency NetChannel allows you to configure following parameters for Latency (Delay Type): Fixed delay (fixed-time) All network data packets packet from source to destination takes constant amount of time. For example, if use ‘Fixed Delay’ of 100ms, then all packets will be delayed by 100ms. This can be verified using a simple ping test to host on the local network and it will show the delay of 100ms. If delay is configured in both directions, source to destination and destination to source, ping time will be the sum of both delays. Random Mean delay NetChannel allow you to configure the Delay type as Random. For random mean delay, you need to specify delay time and variation time. Actual delay will be a random delay with mean delay +/- variation. Also you can select any one of two type of delay: Purely random delay: All delay times are purely random. Each delay sample is independent. Co-related random delay: Each delay sample is co-related to previous delays. In real world, noise is known to happen in burst that can be best explained by co-related randomness.

Packet Loss Fixed packet loss The number of packet loss is always constant. Fixed percentage of packets is lost in every transaction. NetChannel allow you to configure the packet loss in percentage. Co-related random packet loss The number of packet loss is not fixed. NetChannel also allow you to configure the packet loss with co-relation value in percentage. Higher the co-relation more will be the burstiness of packet loss.

Packet Duplication Packet Duplication in Network with or without correlation.

Packet Reordering

Demo Step 1 - Add Routes in the User Host Machines and verify it Step 2 - Create a Tunnel Step 3 – Verify Tunnel is working fine
