Abstract

A scenario is parsed to determine a set of declarations that define creation of a simulated network having a plurality of network elements, wherein the set of declarations define a type and a quantity for each of the plurality of network elements and defines at least one technology type for a plurality of mock inventory messages to be output from a network simulation of the simulated network. Normalized versions of the plurality of network elements are created based on the type and the quantity defined by the set of declarations. The network simulation of the simulated network is executed and includes outputting the plurality of mock inventory messages that include attributes and status of the plurality of network element from a perspective of the at least one technology type.

Dependent claims

A method comprising:

parsing a scenario to determine a set of declarations that define creation of a simulated network having a plurality of network elements, wherein the set of declarations define a type and a quantity for each of the plurality of network elements and defines at least one technology type for a plurality of mock inventory messages to be output from a network simulation of the simulated network;
creating normalized versions of the plurality of network elements based on the type and the quantity defined by the set of declarations, wherein creating the normalized versions comprises creating a first normalized version of a first network element that comprises,
determining whether the first network element is composed of other network elements;
and
in response to determining that the first network element is composed of the other network elements,
creating each of the other network elements;
determining connectivity among the other network elements;
and
mapping the other network elements together based on the connectivity;
storing the normalized versions of the plurality of network elements in a first normalized inventory;
and
executing the network simulation of the simulated network, wherein executing the network simulation comprises,
outputting the plurality of mock inventory messages that include attributes and status of the plurality of network element from a perspective of the at least one technology type.
