Abstract
A method for operating a constrained device within a network is disclosed. The constrained device is configured with a plurality of data objects and a mapping between at least one of the data objects and a multicast address. The method includes detecting that the constrained device should send a notification 104 and determining a topic to which the notification relates. The method further includes, if the topic corresponds to a data object, retrieving the data object to which the topic corresponds, retrieving a mapped multicast address corresponding to the data object, and posting the notification to the retrieved multicast address.

A method for operating a constrained device within a network, the constrained device being configured with a plurality of data objects and a mapping between at least one of the data objects and a multicast address, the method comprising:
- detecting that the constrained device should send a notification;
- determining a topic to which the notification relates;
- responsive to the topic corresponding to a data object, retrieving the data object to which the topic corresponds;
- responsive to the topic corresponding to a data object, retrieving a mapped multicast address corresponding to the data object;
- and
- responsive to the topic corresponding to a data object, posting the notification to the retrieved multicast address.
A method for managing a constrained device within a network, the constrained device being configured with a plurality of data objects, the method comprising:
- configuring the device with a mapping between at least one of the data objects and a multicast address;
- instructing the device to publish notifications relating to a data object by posting the notifications to a mapped multicast address corresponding to the data object;
- and
- instructing the device to subscribe to notifications relating to a data object by listening to a mapped multicast address corresponding to the data object.
A constrained device, the constrained device being configured with a plurality of data objects and a mapping between at least one of the data objects and a multicast address, the constrained device comprising:
- a processor;
- and
- a memory, the memory containing instructions executable by the processor that, when executed by the processor, cause the constrained device to,
- detect that the constrained device should send a notification,
- determine a topic to which the notification relates,
- responsive to the topic corresponding to a data object retrieve the data object to which the topic corresponds,
- responsive to the topic corresponding to a data object, retrieve a mapped multicast address corresponding to the data object, and
- responsive to the topic corresponding to a data object, post the notification to the retrieved multicast address.
A manager for managing a constrained device, the constrained device being configured with a plurality of data objects, the manager comprising:
- a processor;
- and
- a memory, the memory containing instructions executable by the processor that, when executed by the processor, cause the manager to,
- configure the device with a mapping between at least one of the data objects and a multicast address,
- instruct the device to publish notifications relating to a data object by posting the notifications to a mapped multicast address corresponding to the data object, and
- instruct the device to subscribe to notifications relating to a data object by listening to a mapped multicast address corresponding to the data object.
