Abstract: A system and method for validating proof of transit of network traffic through network nodes (N), the node (N) comprising a set of input interfaces (20) receiving incoming packets, a first module (A) to identify a matching route within a routing table (23) and storing means (22) to provide next modules (B, C, D) with two private keys if the packet is matched and/or the packet metadata includes OPoT information. The second module (B) decrypts the OPoT metadata using the first private key associated to the link of the node from which the incoming packets are received. The node (N) has SSS metadata to be processed by a third module (C) for the correct generation of cumulative validation parameters. When the SSS process is finished by the third module (C), the fourth module (D) re-encrypts the OPoT metadata using the second private key before packet forwarding to the subsequent node in the path through output interfaces (21).

Abstract: The method comprising: receiving, a controller (106), traffic packets from a device, each one of said traffic packets including a VLAN tag indicating a destination of a second device; analyzing, by a first monitoring unit (101) during a period of time, the bytes content of said received packets and reporting said analysis to said controller (106); receiving, said controller (106), said plurality of different subcarriers to be used for said sending; adding, by a tag unit (102), an embedded S-VLAN tag to said analyzed packets identifying to which subcarrier and to which sliceable bandwidth variable transponder (105) each tagged traffic packets per destination is going to be sent; sending said S-VLAN tagged traffic packets to a switch (104), the latter forwarding them to a given port of said identified sliceable bandwidth variable transponder (105) for sending them via different sub-carriers to its corresponding destination, said plurality of different sub-carriers following a same or different path.

Abstract: The method updating the status of a network by means of a protocol of the control plane of said network and in response to a path request from at least a path computation client (PCC) pre-reserving during a reserved period of time (Tres), by at least one path computation element (PCE), a plurality of network resources in at least one traffic engineering database (TED) of the at least one PCE. The method dynamically modifying by a timer policy said reserved period of time (Tres) by at least using information data regarding the delay of said control plane. The system of the invention is adapted to implement the method of the invention.

Abstract: The method comprising receiving, an ALTO server at a network layer, a request from an ALTO client at an application layer to obtain network cost for a connection; computing, the cost information concerning PIDs stored in the ALTO server and adapting, by a request controller, the computed cost information to an ALTO information further sending it to the ALTO server and the latter to said ALTO client; receiving, by a provisioning server, a request from a provisioning client to compute a path for setting up a connection between said PIDs and transmitting said request to a provisioning controller; mapping, the provisioning controller, said received request from the provisioning server into network addresses and computing said path according to said network addresses; and comparing, a network cost of the computed path with a cost information previously stored by the request controller in a request database.

Abstract: The system comprising an application CSO gateway coupled to an application layer that configures and monitors a plurality of Data Center Elements storing computing resources; a network CSO gateway coupled to a network layer that configures and monitors a plurality of Network Elements and to receive requests from said ACG to configure connections, wherein the system further includes a Client entity coupled in an already deployed Network Element or in a Data Center Element configured to monitor a segment of the network where said Client entity is found; an IT-Aware Network Controller coupled to said network layer configured to run operations in and from the network regarding information of said monitored network information and of said Data Center Elements; and interfaces coupling the different elements of the system allowing the interconnection and communication between them. The method of the invention is intended to be implemented by the system of the invention.
