Abstract
This disclosure relates to a data packet forwarding unit configured to forward data packets within a software defined network on the basis of a set of data packet forwarding rules, the data packet forwarding unit comprises a memory configured to store the set of data packet forwarding rules and a set of access rules and an access control entity configured to control the access to the set of data packet forwarding rules on the basis of the set of access rules.
Claims12
A data packet forwarding unit configured to forward data packets within a software defined network (SDN) on the basis of a set of data packet forwarding rules, the data packet forwarding unit comprising:
- a storage unit configured to store the set of data packet forwarding rules and a set of access rules;
- and
- an access control entity configured to control access to the set of data packet forwarding rules on the basis of the set of access rules.
A method of operating a data packet forwarding unit configured to forward data packets within a software defined network (SDN) on the basis of a set of data packet forwarding rules, the method comprising:
- receiving a control message from a data packet forwarding unit, wherein the control message comprises a data packet forwarding rule and an identifier for identifying a control entity which generates the control message;
- and
- controlling access to the set of data packet forwarding rules on the basis of a set of access rules and the identifier.
A non-transitory computer readable storage medium storing instructions executable by a computing system for forwarding data packets within a software defined network (SDN) on the basis of a set of data packet forwarding rules, when executed by the computing system, the instructions cause the computing system to perform steps comprising:
- receiving a control message from a data packet forwarding unit, wherein the control message comprises a data packet forwarding rule and an identifier for identifying a control entity which generates the control message;
- and
- controlling access to the set of data packet forwarding rules on the basis of a set of access rules and the identifier.
