Detailed Description

A simple module to configure all the services in a scenario and their parameters.

This module is accessible from any other module that needs this information, so we avoid declaring the same thing again and again.

Usually it is going to be accessed by the queue modules that need to take under consideration the service names and priorities. If there is no such module, the default values are going to be applied.

[virtual]

Return the index of the service with the maximum priority.

                                         {
      double max_p=-1;
      int max_idx=0;

            if (srvs[i].priority > max_p){
                  max_p   = srvs[i].priority;
                  max_idx = i;
            }
      }

      return max_idx;
}

int ServiceConfig::getLowPriorityService

[virtual]

Return the index of the service with the minimum priority.

                                        {
      double min_p=100;
      int min_idx=0;

void ServiceConfig::initialize

[protected, virtual]

Read the configuration (parameters from the .ini file) and initialize the srvs members.

      if (sp.size() != services.size() || sp.size() != vlanmap.size() || sp.size() != msrs.size() ||sp.size() != mrrs.size() )
            error("ServiceConfig: You must configure a priority, a vlan  and an MSR-MRR for each service. \n - Vlan ID"
                        " 0 means no vlan (native) \n - MSR -1 means unlimited service \n - MRR -1 means we don't care");

      // Initialize the map
      for (uint32_t i=0; i<sp.size(); i++){
            SrvItem sit;
            sit.name = services[i];
            sit.priority = sp[i];
            sit.vlan = vlanmap[i];
            sit.msr = msrs[i];

            srvs.push_back(sit);
      }

      char buf[50];
      sprintf(buf, "%d Services", (int)srvs.size());
    getDisplayString().setTagArg("t",0,buf);
