Do you believe that a network node is conforming to the standards? We can tell you.
x-fabric provides conformance tests for a wide range of network technologies and protocols, from the ATM physical layer, IP routing protocols up to voice signalling protocols.
Conformance tests evaluate, step by step, if a given system handles protocol rules as defined in the standard. The test result gives you the certainty that a given network node will have a high degree of interoperability to other network nodes. Further, in case of malfunctions in a network, conformance tests of the individual network nodes discloses those that do not fully conform to the standards.
