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
