Abstract

A method for operating a communications network having a number of nodes in accordance with ITU Standard Q704, wherein when the message transfer part of a node is restarted, the MTP restart procedure in accordance with the protocol is initiated by this node only with those adjacent nodes in which the MTP restart procedure is implemented.

Claims

1. A method for operating a communications network having a plurality of nodes in accordance with an ITU Standard Q704 protocol, the method comprising the steps of:

determining when a message transfer part of a node is restarted; and

initiating, by the node, an MTP restart procedure in accordance with the protocol only with the adjacent nodes in which the MTP restart procedure is implemented.

2. A method for operating a communications network as claimed in claim 1, the method further comprising the step of storing, in a database for each node, an attribute, which indicates one of implementation and non-implementation of the MTP procedure in the respective node, for each linkset which identifies an adjacent node.

3. A method for operating a communications network as claimed in claim 1, the method further comprising the step of storing, in a central database, an attribute, which indicates one of implementation and non-implementation of the MTP procedure in the respective node, for all the nodes in at least a section of the communications network.

4. A method for operating a communications network as claimed in claim 1, wherein communications traffic with the adjacent nodes in which the MTP restart procedure is not implemented starts essentially immediately after activation of links in a corresponding linkset, at a latest point in time after receiving “

traffic restart allowed”

messages from the other adjacent nodes.

5. A method for operating a communications network as claimed in claim 1, wherein, upon restarting the message transfer part of a node which is not itself designed to carry out the MTP restart procedure, the adjacent nodes start communications traffic to the node essentially immediately after activation of links in a corresponding linkset, immediately after transmitting routing information, which is terminated by a “

traffic restart allowed”

message, to a starting node.
