- FIG. 2 schematically shows a generic switch (local or central) of an MPLS network of the infrastructure 10 and the various services it performs.
- the MPLS protocol comprises, basically, a plurality of services, capable of being executed by each MPLS switch.
- each switch notably implements a service 1000 for defining paths through the MPLS network, called LSP (Label Switched Paths) paths.
- LSP Label Switched Paths
- each switch also implements a service 1 100 of fault detection.
- each switch implements a service
- a single LSP path is defined for each possible pair of switches within the same network, and this for each network 100, 200, 300 constitutive infrastructure.
- the blue LSP path defined between a first blue switch and a second blue switch is complementary to the red LSP path defined between the first red switch associated with the first blue switch and the second red switch associated with the second blue switch. In this way the blue and red frames of the same communication do not pass through any link or any common switch.
- a blue path B is defined statically between the central blue MPLS node 1 12 and the local blue MPLS node 132, as well as a path red R between the central red MPLS node 1 14 and the local red MPLS node 134.
- the blue path B will be in a counterclockwise direction and the red path will be in a clockwise direction R, so that the blue and red frames of the same communication does not pass through any link or common switch.
- each switch also implements a service 1400 for defining SDP paths (in the acronym "Service Distribution Point”).
- data to be routed in an MPLS network between a source node and a destination node, is encapsulated in a specific datagram, whose frame is adapted to be routed through the MPLS network between the source node and the destination node.
- Such specific encapsulation transmission between a source node and a destination node is also referred to as a tunnel link between the source node and the destination node.
- the SDP path definition service 1400 makes it possible to define the properties of the tunnel link between a source switch and a switch destination, and this for each possible pair of switches within the same network infrastructure.
- the SDP paths of a network constitute a subset of the LSP paths defined on this network.
- SDP paths are thus configured to limit the use of resources on an MPLS node. For example, for a network, a tunnel link is provided between the central switch and each local switch of a given color, but no tunnel link is created directly between two local switches of a given color.
- an SDP path has an attribute that can take either the value "Spoke SDP" or the value "Mesh SDP".
- a frame traveling on a SDP path "Spoke SDP” can pass to another SDP path, regardless of the value of its attribute.
- a frame running on an SDP path "Mesh SDP” can only pass to an SDP path "Spoke SDP”.
- an SDP path between a local switch and a central switch is configured to take the value "Spoke SDP" so as to allow point-to-point communication between two sections of the same sector, for example 4 and 5 through the network 100.
- An SDP path between two central switches of different sectors is configured to take the value "Mesh SDP", so as to allow a multipoint communication between two sections of different sectors, for example 5 and 6 through the networks 100, 300 and 200.
- the bandwidth and latency of the infrastructure 10 are guaranteed by the MPLS quality of service (QoS) characteristics.
- QoS quality of service
- an MPLS network provides higher data transfer rates (up to 10 Gbps bandwidth) than an SDH network with the same quality of service.
- an MPLS network makes it possible to achieve more flexible topologies, notably allowing extensions of the infrastructure without having to reconfigure the entire network, but only the new networks associated with the new sections of track at a given time.
- extension of the rail network, or the only local blue and red connectors for the aggregation of a new local network by an existing network In particular, it is possible to prepare an offline configuration and to configure or modify the configuration of an existing network quickly, thus minimizing the downtime of rail network operation.
- a ring MPLS network aggregating local area networks by channel sector makes it possible to reduce the length of the cables (in this case optical fibers) used to connect the network equipment to each other, with the key being a reduction infrastructure deployment costs.
- an IP-MPLS network makes it possible to implement a data priority / segregation service, allowing the use of the network for the communication of data other than signaling data.
- the implementation of the segregation service ensures that the communication of the signaling application data having a high priority attribute is not affected by the data communication of other applications having a priority attribute low, especially during an overflow of non-priority data.
- An MPLS network allows a certain flexibility in the allocation of the bandwidth between different applications. This ensures bandwidth for each application and, in the event of bandwidth availability, dynamically allocate an increase in bandwidth to an application up to a predefined maximum for that application. This ability to circulate heterogeneous frames on the same network allows a rail network operator to avoid having to deploy an independent communication network dedicated to these additional applications.
- FIG. 1 is particularly simple. Numerous variations are possible in terms of the number of sections, the number of sectors, in order to aggregate the sections within sectors, the number of ground computers managing one or more sectors, etc.
