A method to control communication traffic in a communication network. The traffic includes application-level messages between a client and a server having a private network address. The method includes the steps of: sending by the client a request message requesting a service to the server using a first public network address associated with the server; processing the request message at an intermediate logic unit logically positioned between the client and the server; and receiving an alert signal at the intermediate unit. Upon receipt of said alert signal, the method provides for: mapping the private network address of the server to a second public network address associated with the server; and instructing the client to send the request message to the second public network address of the server, routing to the server only request messages directed to the second public network address.

Method and apparatus to control application messages between client and a server having a private network address

A method for localizing an optical network termination (ONT) of a passive optical network is disclosed. The passive optical network comprises an optical line terminal (OLT) and an optical distribution network (ODN) having a plurality of optical links. The ONT is connectable to the OLT by a given optical link of the optical distribution network. The method includes the steps of detecting that the ONT has been connected to the OLT by an optical link of the optical distribution network; determining length information indicative of a length of the optical link; comparing the length information with a reference length information indicative of a length of the given optical link; and if the length information matches the reference length information, localizing the ONT by confirming that it is connected to the OLT by the given optical link.
