Overlay/Underlay Routing Issues in Wireless Mesh Networks
Source: University of Naples
Recent analyses of the network traffic show that an ever growing portion of it is generated by user communities that share their own resources in a peer-to-peer fashion. Internet Service Providers' attitude towards peer-to-peer applications, so far, has been of considering them more as potential threats rather than as an opportunity and a customer demand to second. This is mostly due to the fact that peer-to-peer applications still represent a significant traffic engineering challenge for ISPs, since they tend to build their own overlays in a way that is largely independent of the Internet routing and topology.
