Abstract:
Systems and methods are provided for packet handling and steering in a service function chaining network such that the full metadata associated with a packet need not be appended to the packet itself.
Abstract:
A method and device for sending a request (R) from a requesting machine (H) to a domain name server (1, 2, 3). A prior test of the validity of the destination telephone number (NTEL) of the request (R) is executed automatically and locally to the requesting machine (H) relative to a database (BD) local to said requesting machine (H) in order to forward the request (R) from the requesting machine (H) to the domain name server (1, 2, 3) only if its telephone number (NTEL) passes said test.
Abstract:
Systems and methods for maintaining privacy of security protocol parameters are provided. A node receives an encrypted packet and determines if the Security Parameters Index (SPI) value has been updated. The node can modify its stored SPI value(s) accordingly and process the encrypted packet.
Abstract:
A domain name server includes a zone file containing partitioning rules that define the partitioning of all subfolders of this domain into subzones. The DNS data of each of these subzones is hosted by a partition server that is able to obtain from the zone file information for identifying the partition server able to respond to a query sent by a client to obtain a DNS folder.
Abstract:
A method of secure mutual identification of nodes (Nn) in a communications network comprising for each node a file (Fn) containing parameters descriptive of the node, each parameter being indexed by a cryptographic identifier of the node and an identifier of the parameter. An interface (IR) broadcasts from the node a message containing the cryptographic identifier of said node to the other nodes of the network. A unit (UC) transmits an identification request containing the cryptographic identifier of a first other node and the identifier of a parameter of said first other node requested by said node. A unit (HF) searches the file for a part of a parameter requested by a second other node as a function of the cryptographic identifier of said node and the identifier of the parameter transmitted by the second other node, and the interface transmits the part found of the parameter requested by the second other node to said second other node.
