A method for interworking between a first protocol entity (12) adapted to operate in accordance with a stream reservation protocol for reserving resources for a data stream along a stream path of the data stream and a second protocol entity (14a, 14b) adapted to operate in accordance with a routing protocol for distributing information in a communication network (20) is described. The method comprises sending (S22), from the first protocol entity (12) to the second protocol entity (14a, 14b), a request for stream path formation indicating, for a data stream to be sent, a stream path in the communication network, (20). The method also comprises determining (S24), by the second protocol entity (14a, 14b) the stream path formation for the stream path based on the request, sending (S26), from the second protocol entity (14a, 14b) to the first protocol entity (12), the determined stream path information, and initiating (S28), by the first protocol entity (12), a resource reservation procedure for reserving resources in response to receiving the stream path information. Therefore an easy and efficient interworking between different protocol entities (12, 14a, 14b) with respect to stream path establishment and resources reservation can enabled. |

1. A method for interworking between a first protocol entity (12, 202, 702, 802, 902) adapted to operate in accordance with a stream reservation protocol for reserving resources for a data stream along a stream path of the data stream and a second protocol entity (14a, 14b, 203, 703, 803, 903) adapted to operate in accordance with a routing protocol for distributing information in a communication network (20, 401, 501, 601), the method comprising:
sending (S22, 1102, 1203), from the first protocol entity (12, 202, 702, 802, 902) to the second protocol entity (14a, 14b, 203, 703, 803, 903) , a request for stream path information indicating, for a data stream to be sent, a stream path in the communication network (20, 401, 501, 601), determining (S24), by the second protocol entity (14a, 14b, 203, 703, 803, 903), the stream path information for the stream path based on the request, sending (S26, 1107, 1206), from the second protocol entity (14a, 14b, 203, 703, 803, 903) to the first protocol entity (12, 202, 702, 802, 902), the determined stream path information, and initiating (S28), by the first protocol entity (12, 202, 702, 802, 902), a resource reservation procedure for reserving resources in response to receiving the stream path information. |
