| Abstract: |
A communications protocol that is used in a network having a hub device connected to a plurality of peripheral devices includes a synchronization beacon frame that is broadcast by the hub device to the peripheral devices for permitting the peripheral devices to synchronize to the network, a token frame that is broadcast by the hub device to the peripheral devices for allocating network bandwidth among the peripheral devices, a status response frame that is transmitted by the peripheral devices to the hub device for indicating whether the peripheral devices have data to transmit to the hub device, and a data frame. The synchronization beacon frame includes a beacon identifier that identifies a frame as the synchronization beacon frame, and a hub identifier that identifies an address of the hub device. The token frame includes a data portion that schedules a data transmission on the network, and a status response portion that schedules a status response transmission on the network. The status response frame includes a data transmission field that indicates whether a corresponding one of the peripheral devices has data to transmit to the hub device. The data frame includes data transmitted between the hub device and the peripheral devices.

What is claimed is:
1. A communications protocol used in a network having a hub device connected to a plurality of peripheral devices, comprising:
- a synchronization beacon frame, broadcast by the hub device to the peripheral devices for permitting the peripheral devices to synchronize to the network, including:
- an attach field that indicates whether the hub device is permitting new peripheral devices to attach to the network,
- a beacon identifier that identifies a frame as the synchronization beacon frame, and
- a hub identifier that identifies an address of the hub device;
- a token frame, broadcast by the hub device to the peripheral devices for allocating network bandwidth among the peripheral devices, including:
- a data portion that schedules a data transmission on the network, and
- a status response portion that schedules a status response transmission on the network;
- a status response frame, transmitted by the peripheral devices to the hub device for indicating whether the peripheral devices have data to transmit to the hub device, including:
- a data transmission field that indicates whether a corresponding one of the peripheral devices has data to transmit to the hub device; and
- a data frame including data transmitted between the hub device and the peripheral devices.
