Interoperability testing has become a requirement on companies that implement multi-vendor networks. To meet this requirement, network and storage vendors and managers have four options.
1. Establish an interoperability lab, an expensive and time consuming.
2. Use a third-party interoperability lab such as Isocor or the
. University of New Hampshire
3. Generate a proof of idea lab, such as Cisco labs or Spirent Communications.
These laboratories usually connect devices with a copper cable or fiber optics and run the tests. This essay reflects a best case that is useful for testing the interoperability of base line, but do not represent how devices interoperate in actual network. It is analogous to testing the automatic pilot method of an airplane to see if it could land the plane in ideal weather. While the check is the plane can land on it an ideal day, not a predictor of how the method will behave in a variety of climatic conditions under which an airplane must operate.
Sometimes fiber coils are used to generate the delay in wide area networks. While this is an improvement over connecting cables, there are four major limitations to the proof of idea and interoperability testing with coils of fiber:
1. Spools of fiber can not provide dynamic tests. The trials were stopped and restarted by hand to modify the spool of fiber for a different length.
2. Spools of fiber are expensive and impractical. Imagine the cost associated with moving a spool 50,000 kilometers of fiber to another laboratory.
3. Spools of fiber only provide delay. Not addressing the shortcomings that there are several others in a network.
It is as if they have improved our method of auto-pilot to include fixed amounts of wind from one direction. Factors such as fog, rain, snow and wind shears are still ignored in testing. The climatic conditions are dynamic and multifaceted. Testing less than one condition is not a realistic check. As with time, so do networks. Deficiencies in the actual networks are not limited to a single issue.Anue Network Emulators permit his plane to land with any combination of adverse climatic conditions.Anue Network Emulators enable clever network and storage providers for the characterization and validation of application performance based on multiple factors. These factors include dynamic delay represents a distance of 50. 000 km, restlessness, bit errors, the sequence of packets and loss.
