Conditional routing device and method

A Forwarder device configured for use in a network, the Forwarder device comprising:

• at least one communication interface configured to:
• receive a first request for data from a Consumer device or a second Forwarder device, the first request comprising an identifier of requested data and a condition;
• send a second request for the data to a Producer device or a third Forwarder device in the network, the second request comprising at least the identifier of the data;
• receive data corresponding to the requested data from the Producer device or the third Forwarder device;
• and
• send the received data to the Consumer device or the second Forwarder device;
• and
• at least one hardware processor configured to:
• instruct the at least one communication interface to send the received data to the Consumer device only in case the received data satisfy the condition;
• wherein the at least one hardware processor is further configured to determine if the received data satisfy the condition only in any of the following cases:
• the Forwarder device received the first request from the Consumer device;
• the Forwarder device sent the second request to the Producer device.

A method at a Forwarder device in a network, the method comprising:

• receiving, by at least one communication interface, a first request for data from a Consumer device or a second Forwarder device, the first request comprising an identifier of requested data and a condition;
• sending, by the at least one communication interface, a second request for the data to a Producer device or a third Forwarder device in the network, the second request comprising at least the identifier of the data;
• receiving, by the at least one communication interface, received data corresponding to requested data from the Producer device or the third Forwarder device;
• determining, by at least one hardware processor, whether the received data satisfy the condition, wherein the determining is performed only in any of the following cases:
• the Forwarder device received the first request from the Consumer device;
• the Forwarder device sent the second request to the Producer device;
• and
• sending the requested data to the Consumer device or the second Forwarder device only in case the received data satisfy the condition.
