| 1. A method of sending an information package from a first data network to at least one second data network through a communications
network, selected from a group consisting of a SDH and a SONET network, said communications network comprising a first plurality
of access points and a second plurality of MPLS switches, a third plurality of paths defined from each of said access points
to an Ethernet switch including MPLS switching capabilities via at least one of the first plurality of MPLS switches, a fourth
plurality of paths defined from said Ethernet switch including MPLS switching capabilities to each of said access points via
at least one of the second plurality of MPLS switches, said method comprising:
sending said information package from said first network to a specific access point of said first plurality, wherein said
communications network comprises a SDH and a SONET network,
receiving said information package at said specific access point and adding a header to said information package, said header
including an MPLS label,
sending said information package including said header from said specific access point to said Ethernet switch including MPLS
switching capabilities via a path of said third plurality,
said Ethernet switch including MPLS switching capabilities switching said information package including said header to at
least one of said paths of said fourth plurality,
receiving said information package including said header at at least one further specific access point corresponding to said
at least one second data network,
removing said header from said information package, and
sending said information package from said at least one further specific access point to said at least one second data network.
