1. A method for use in a communications network having plural nodes, comprising:
- receiving, by a first node, a capability list that has a predefined format and includes plural entries identifying corresponding data processing functions supported by one or more nodes along a communications path of a communications session involving the first node; and
the first node adding at least one additional entry into the capability list in response to determining that the first node supports a data processing function that is not identified in the capability list.

Abstract
In a communications network having plural nodes, a first node receives a capability list that has a predefined format and includes plural entries identifying corresponding data processing functions supported by one or more nodes along a communications path of a communications session involving the first node. The first node adds at least one additional entry into the capability list in response to determining that the first node supports a data processing function that is not identified in the capability list.

13. A node comprising:
-
a first termination point and a second termination point;
a processor; and
a coordination module executable on the processor to;
receive, at the first termination point, a first capability list containing entries identifying data processing functions supported by certain nodes in a communications path of a communications session in which the node is involved;
determine whether the received first capability list is different from a previously received capability list at the first termination point; and
in response to determining that the received first capability list is different from the previously received capability list, send a second capability list previously received from the second termination point, where the second capability list is sent from the first termination point. - View Dependent Claims (14, 15, 16)

17. An article comprising at least one storage medium that contains instructions that when executed cause a first node to:
-
receive a capability list that has a predefined format and includes plural entries identifying corresponding data processing functions supported by one or more nodes along a communications path of a communications session involving the first node; and
add at least one additional entry into the capability list in response to determining that the first node supports a data processing function that is not identified in the capability list. - View Dependent Claims (18, 19, 20)
