Network emulation with data rates up to 10 Gbps 

The PacketStorm IP Network Emulators and simulators reproduce the unfavorable conditions of IP Networks and WANs in a controllable and repeatable lab setting. PacketStorm is the Industry leader of Layer 2 and Layer 3 WAN emulation and network bandwidth simulation.

Network Emulation

The Internet, private wide area networks, and cloud services represent some of the aspects that connect the user to their application. As users demand faster response and more complex data from their applications, the networks carrying this data are under greater pressure to meet these expectations. To truly test out applications before rolling it out to the users, network emulation must be used. Network emulation is also referred to as WAN emulation. 

Network emulation is used by manufacturers, service providers, and applications developers to verify the robustness of their network product or application. A wan emulator recreates the real world effects seen in the network. Standard features of a network emulator include filtering, impairments, modifiers, and routing.

Filtering allows the wan emulator to separate traffic into different groups to represent different networks. Therefore, a network emulator emulates multiple network scenarios between two emulator ports. Even though end devices are only feet apart and connected to the same server through the emulator, device “A” and device “B” could be viewed to be on different sides of the world by the server.

Typical uses include WAN emulation and network simulation for Enterprises, network devices, and software applications. The family of IP network emulators ranges from the Tornado software to the 60 Gbps PacketStorm6XG. Most of the hardware IP network emulators and the PSCapture software have network recording capabilities. Network emulation is implemented by using filters, impairments, and modifiers.

Each IP network emulator is designed for a particular application. The Tornado software emulator addresses low bandwidth and simple network applications. The PacketStorm200E emulator provides network emulation in a portable chassis. The PacketStorm1800E emulator addresses multiple 10/100 Mbps and legacy interface applications. The PacketStorm400E, Hurricane II, and Hurricane III are designed for Gigabit applications.

Video Test Solutions

PacketStorm has developed products to address video application test requirements. Products provide network emulation, PTP switch emulation, capture video files, replay video files, and replicate video streams. These products have a number of unique video application features such as: DASH dynamic network emulation, FEC Aware network emulation, Hitless network emulation, large capture and replay files, and video server farm stream emulation. Video applications include: DASH, FEC, VSF TR-03 and TR-04, Hitless/Seamless Protection, Video Generation/Replication, and Video Transport.

DASH

Dynamic Adaptive Streaming over HTTP (DASH) is also referred to as Over The Top (OTT). OTT examples include: Netflix, Redbox, HULU, and YouTube. Other video clients besides DASH are Silverlight, HLS, and Flash.

FEC Testing

Forward Error Correction (FEC) is a method to transmit additional packets (FEC Row and Column packets) to overcome packet loss. SMPTE 2022 1/2 and SMPTE 2022 5/6 are standards that specify the transmission specifications. FEC testing includes Active Video, burst loss, and FEC aware tests.

VSF TR-03 & TR-04

VSF TR-03 & TR-04 are standards that use RFC 4175, AES 67, and SMPTE 2022 streams to send multi media over IP.

Hitless / Seamless Protection

Hitless or also called Seamless Protection is a method to transport video between two points without any loss. There are two redundant transport streams that the receiver must use to overcome any loss on either stream.

Set Top Box Testing

ITU G.1050 and TIA-921B are standards that use real-world data from service providers to develop network emulation models. Using these standards, users test susceptibility of a Set Top Box (STB) to real-world network impairments based on, packet loss, jitter, delay, and burst packet jitter etc.

Video Generation / Replication

Real video data is required to truly test video applications. Video replication eliminates the need for a large number of servers or encoders to generate high capacity video.

Video Transport

Network emulation validates the ability of video decoding equipment to handle transport stream error and to verify network equipment properly detects alarm conditions.

Network Simulation

Network simulation covers a wide range of different concepts. However, there are two main network simulation concepts: a software program simulating the interaction of network devices and equipment to simulate a network with real data.

The network simulation software is to test the end to end application behavior on different network designs. Again the network simulation is done completely in software.

The other network simulation is to test application performance with real data. Even though it is more accurate to call real data testing as network emulation, most people still refer it as network simulation.

Some examples of network simulation include: enterprise networks, satellite networks, networks with remote data centers, service provider networks, networks with cloud based elements, and application based networks such as video delivery services.

Just as testing with actual real data vs. software provides a closer alignment to “real network” testing, testing with live traffic vs. synthesized data gets even closer. Network devices operate differently depending on the interaction with the traffic. It is common to see a router affect live traffic differently than synthesized video traffic, and therefore it is best to get as close as possible to the real network to ensure all issues are fully tested and reduce deployment risk
