LAN and WAN Emulation Services
When preparing to roll out new applications, services or entire systems, the ability to accurately gauge performance across your WAN, MAN or LAN can be the key to the success of the entire project. With our extremely versatile Network Emulator (NE), it is now possible to do just that.
The Network Emulator uses the concept of virtual interfaces (VI) to represent different network segments. You can configure a number of parameters that influence the traffic flows to emulate a specific VI – such as bandwidth, latency, packet loss, delay, errors and packets transmitted out of sequence. Traffic entering any of the Emulator’s physical interfaces passes through, and is influenced by, each virtual interface defined in a sequence before finally exiting another physical interface.
This unique approach allows us to accurately gauge a wide range of symmetrical and asymmetric circuits such as:
- High latency WANs (National, International and Satellite)
- Asymmetric Digital Subscriber Line (ADSL)
- Wireless networks (3G, WiFi, WiMAX)
- Jittery networks that can seriously affect VoIP deployments
- Networks that lose/damage traffic
- QoS-based networks (i.e. Multi-Protocol Label Switching - MPLS)
- Point-to-Point (Asynchronous Transfer Mode - ATM)
- VLANs
- Routed networks
The diagram below shows an example of a 3 physical interface emulation where, by adjusting VI parameters, each network path can have different characteristics applied to it, in order to create an accurate emulation of a realistic network.
NE Key Points:
- Multiple comprehensively configurable Virtual Interfaces
- Network and vendor independent
- Rapid and simple deployment
- Future-proof multi-protocol deployment capability
- Low cost instrumentation
- Built to IETF and ITU International Standards
The NE is available both as a rack-mount or portable appliance, for hire or purchase, with or without the services of an experienced Network Consultant.
Modern LAN and WAN services can be extremely expensive, and to embark upon a network upgrade project without using the NE to gauge application/service performance from a user perspective can at best cause unnecessary expense and at worse an unusable application or service.
