Method and arrangement for dynamic signalling
First Claim
1. A method for dynamic signalling in a network having a plurality of nodes and a bandwidth, said method comprising:
- dividing said bandwidth into a plurality of time-sequential cycles;
dividing said plurality of time-sequential cycles into control slots for network control signalling and data slots for transferring data; and
converting data slots into control slots or converting control slots into data slots in order to change the signaling capacity of a node.

Abstract
The present invention relates to a method and an arrangement for dynamic signalling in a network, such as a Dynamic Synchronous Transfer Mode (DTM) network. The network'"'"'s bandwidth is divided into cycles, which in turn are divided into control slots for control signalling and data slots for transferring data. Preferably, each or certain nodes have a node controller, which control the access to slots. According to the invention data slots are converted into control slots, called dynamic control slots, or control slots are converted into data slots in order to change the signalling capacity of a node. The dynamic control slots may be used for point-to-point, multicast or broadcast signalling.

20. A controller for a network containing at least two nodes, the network having a bandwidth divided into cycles, each cycle containing a plurality of slots, the controller comprising:
-
means for dividing the plurality of slots into control slots for control signalling and data slots for transferring data, and means for converting data slots into control slots and/or converting control slots into data slots in order to change the signalling capacity of a node. - View Dependent Claims (21, 22)

23. A node in a network, said node comprising:
-
a bandwidth divided into a plurality of sequential cycles, each cycle divided into control slots for control signalling and data slots for transferring data; and a node controller arranged to convert data slots into control slots and/or to convert control slots into data slots in order to change the signalling capacity of said node.

24. A network comprising:
-
a bandwidth divided into a plurality of sequential cycles, each cycle divided into control slots for control signalling and data slots for transferring data; and a plurality of nodes, wherein at least one of the nodes comprises a node controller arranged to convert data slots into control slots and/or to convert control slots into data slots in order to change the signalling capacity of said node based on the queue length of control signals to be placed in outgoing control slots.
