SENSORS FOR NETWORK TRAFFIC ANALYSIS2
• Aspects like QoS, NP, QoP ,QoE, QoB are everyday more important to be considered in future networks. In general we can talk aboutQoX.
• National Regulatory Authorities (NRA), like in Spain, are interested in monitoring the QoS that ISPs provide.
• In last years our research group has developedseveral solutions to do QoX monitoring

Original Funcionalities
LabQoS Modules
We have designed the architecture of LabQoS to manage control variablesand parameters in a scenario
We have developed an experimental tool to analyse the perceived quality in multimedia services
We have implemented a prototype to demostrate LabQoS Funcionalities

Conclusions
• QoSMETER in an architecture that can solvelogistical problems in the implementation of verygeneral network test scenarios
• LabQoS has developed the intelligence to control how we can modify the conditions of thescenarios as is needed in scientific tests
• These could be interesting to scientific comunity, but…….– There is a lot of work to do
– We need help
