On the converged network, it’s all packets.
The migration of video and voice transmission from traditional networks with dedicated bandwidth to IP networks poses many challenges. Video and voice applications (such as VoIP, IPTV and streaming video) are time sensitive and require high bandwidth. Impairments found in IP networks, such as delay and packet reordering, can have a significant effect on voice and video traffic. As a result, testing triple-play solutions can be challenging. Anue Network Emulators are specifically designed to address these challenges.
Networks engineered to deliver triple-play content must prioritize traffic to guarantee adequate bandwidth and latency metrics for high-bandwidth video applications and medium-bandwidth voice applications while accommodating the variable-bandwidth needs of data traffic. Bursts of data traffic, such as file transfers, must not affect voice or video applications.
Anue Network Emulators function at 100% line rate, and support packet-lengths from 64 bytes to 16K bytes.

To validate that a triple-play implementation manages all these issues properly, the video and VoIP test lab must emulate the network characteristics of the various paths. Anue GEM and XGEM Network Emulators can emulate up to 64 different network profiles simultaneously at full line rate for all packet sizes, enabling you to reproduce with accuracy any network configuration and condition, including delay, jitter, errors, drop, reorder, fragmentation, duplication, buffering, flow control, and bandwidth constraints. GEM and XGEM are a key part of any comprehensive IPTV or VoIP test.
With Anue Network Emulators you can emulate real world network scenarios in the lab–accurately, repeatedly and efficiently–in order to:
- Evaluate the performance of emerging technologies such as Video on Demand (VOD) and VoIP.
- Assess the sensitivity of your voice, video and data applications to variations in traditional QoS parameters such as bandwidth, packet loss, delay, and jitter.
- Determine how resource sharing can lead to degradation of signals due to network congestion.
- Identify the best techniques (buffering, QoS, MPLS, bandwidth shaping) to assure quality of experience for the end user.
- Ensure an acceptable MOS rating through various VoIP testing scenarios.
- Find problems early, before deployment, to improve the quality of your products and services.
- Reduce time to market for triple-play services in order to move into lucrative entertainment markets.
