ABSTRACT:
A method and apparatus for using a service provider network that supports point-to-point channels is disclosed. One or more encryption parameters are associated with a channel from among a set of one or more predefined point-to-point channels provided by the service provider to connect customer points for a customer different than the service provider. Payloads for a particular flow of one or more data packets directed through the channel are encrypted at a first customer point, using the set of encryption parameters associated with the particular channel, to generate a set of one or more encrypted payloads. The encrypted payloads are inserted in the particular flow sent through the channel of the service provider network. The encrypted payloads are decrypted at a second customer point connected to the first customer point by the channel.
