Process to transfer a time division multiplexing (TDM) frame over a MPLS network
View Patent ↗A process to transfer a Time division Multiplexing (TDM) frame ( 1 ) over a MPLS network ( 2 ), the frame including a plurality of time slots (TS 1 , TS 2 , TS 3 ) with specific bandwidths, including—identifying the corresponding bandwidth of the time slots of the frame ( 1 );—creating and reserving into the MPLS network ( 2 ) for each time slot (TS 1 ,TS 2 ,TS 3 ) of the frame a corresponding label switched path (LSP 1 , LSP 2 , LSP 3 ) having a bandwidth substantially identical to the bandwidth of the time slot;—and routing each time slot (TS 1 , TS 2 , TS 3 ) over the MPLS network ( 2 ) through a corresponding label switched path (LSP 1 , LSP 2 , LSP 3 ).
1. A method of transferring a Time Division Multiplexing (TDM) frame over a Multiprotocol Label Switching Architecture (MPLS) network, said TDM frame comprising a plurality of time slots with specific bandwidths, the method comprising:
identifying corresponding bandwidth of the time slots of the TDM frame;
creating and reserving, by a load balancing application component, into said MPLS network for each time slot of the TDM frame a corresponding label switched path having a bandwidth identical to the bandwidth of the time slot; and
routing each time slot over the MPLS network through the corresponding label switched path,
wherein the bandwidth of the corresponding label switched path is automatically adapted to have a bandwidth identical to the bandwidth of the time slot.
2. The method according to claim 1 , wherein said TDM frame is a Synchronous Digital Hierarchy/Synchronous Optical Network Transport Systems (SDH/SONET) frame.
3. A router for transferring a (Time Division Multiplexing (TDM) frame over a Multiprotocol Label Switching Architecture (MPLS) network, said TDM frame comprising a plurality of time slots with specific bandwidths, the router comprising:
a monitoring module which identifies corresponding bandwidth of the time slots of the frame;
a load balancing application component which creates and reserves into said MPLS network for each time slot of the frame a corresponding label switched path (LSP) having a bandwidth identical to the bandwidth of the time slot; and
a routing and forwarding module which routes each time slot over the MPLS network through a corresponding label switched path,
wherein the bandwidth of the corresponding label switched path is automatically adapted to have a bandwidth identical to the bandwidth of the time slot.
4. A SDH/SONET network comprising a router according to claim 3 .
5. The method according the claim 1 , further comprising:
identifying a number and a type of the plurality of time slots.
6. The method according to claim 3 , wherein the monitoring module identifies a number and a type of the plurality of time slots.
7. The router according to claim 3 , wherein the load balancing application component triggers a new load balancing session when creating and adding a new LSP.
8. The router according to claim 3 , wherein the load balancing application component triggers an existing load balancing session when creating and adding a new LSP.
9. The router according to claim 3 , wherein the load balancing application component takes into account a different Quality of Service (QoS) and Class of Service (CoS) of a user the network, generating an order of priority for mapping of different frames.
10. The method of claim 1 , further comprising:
taking into account a different Quality of Service (QoS) and Class of Service (CoS) of a user the network, generating an order of priority for mapping of different frames.
