This prototype optical coupling, which is the interface between the fibre-optic cable and the circuitry, can transmit data at 100Gbps. According to Bell Labs researcher Jean Godin, the same technology could lead to transmissions of 400Gbps over "hundreds of kilometres".
Bell Labs is working on what it calls 'small cells'. Such cells are derived from femtocell technology, which offloads 3G data onto a fixed network so as to reduce the strain on the mobile network.
Small cells would be deployed in high density, along with a new protocol called Not-Mobile IP (NMIP) that is designed to simplify the network. NMIP links terminals such as mobile phones directly with servers, cutting out the need for tunnelling and reducing the network itself to simple switches. In this demonstration, video streaming was maintained despite simulated handover between IP addresses.
Bell Labs is working on new ways of detecting botnets by studying network behaviour.
The research is based on the idea that antivirus protection can be bypassed or disabled, and that firewalls cannot stop use of the HTTP and DNS protocols. Given this, the researchers are trying to characterise the behaviour of botnet-related DNS traffic in particular, so as to make it easier to identify infected machines.
