Return to Home --> How-To
In SimSANs, the network design is referred to as writing network descriptions using NED language shipped with OMNeT++. The following rules should be followed when writing SimSANs network descriptions:
 Must import the following three NED files: Host.ned, Switch.ned, and Device.ned.
 At least one data centre
module must be defined, which contains multiple inter-connected
 A root module must be defined, which contains one or more inter-connected data centres.
 There're 97 parameters that the root module must at least define.
 The network instance against the defined root module must be created. Of all the 97 parameters, 45 are non-customizable and should be initialized in NED file. The reset 52 parameters will can be initialized and customized in omnetpp.ini.
User may refer to Module Tree to get a whole picture about how the SimSANs network is constructed before designing and writing the NED. A sample NED file (SimSANs_V2.ned) is included in the SimSANs Package describing a multi-site network that contains three inter-connected data centres.
