Abstract: Methods for Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) design for IP Multimedia Subsystems (IMS) include determining that a network is a flat MPLS-enabled Voice over Internet Protocol (VoIP) or Unified Communications IMS network including an IMS Core site and excluding Session Border Controllers (SBCs). The network further includes multiple user endpoints (UEs). Responsive to determining that the network is a flat MPLS-enabled VoIP or Unified Communications IMS network, the computer system configures a first set of TE LSPs between each UE and the IMS Core site. The computer system configures a second set of TE LSPs between each UE and each other UE of the plurality of UEs to form a full mesh. A display device of the computer system generates a graphical representation of the network. The graphical representation represents the first set of TE LSPs and the second set of TE LSPs connecting each UE.

Abstract: Methods for Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) design for IP Multimedia Subsystems (IMS) include determining that a network is a hierarchical MPLS-enabled network including a single IMS Core site and multiple Session Border Controllers (SBCs). Responsive to determining that the network is a hierarchical MPLS-enabled network, the computer system configures a first set of TE Label Switching Paths (LSPs) between each SBC of the multiple SBCs and the single IMS Core site. The computer system configures a second set of TE LSPs between each SBC of the multiple SBCs and each other SBC of the multiple SBCs to form a full mesh. The network further includes multiple user endpoints (UEs). The computer system configures a third set of TE LSPs between each UE of the multiple UEs and an SBC of the multiple SBCs. The UE is configured to use the SBC.
