Abstract
A technique for routing one or more service tunnels in a telecommunications backhaul network (110) is provided. The telecommunications backhaul network has a first routing path (132) and a second routing path (134). As to a method aspect of the technique, data of the one or more service tunnels is transmitted on the first routing path (132). A reduction in transmission capacity is detected on the first routing path (134) by means of a first routing path condition. The first routing path condition indicates a state of the first routing path (132). A second routing path condition is determined indicating a state of the second routing path (134) in response to the detected reduction in transmission capacity on the first routing path (132). It is decided upon rerouting one or more of the service tunnels from the first routing path (132) to the second routing path (132) based on both the first routing path condition and the second routing path condition.

17. A method of routing one or more service tunnels in a telecommunications backhaul network including a first routing path and a second routing path, the method comprising:
-
transmitting data of the one or more service tunnels on the first routing path; detecting a reduction in transmission capacity on the first routing path by means of a first routing path condition indicating a state of the first routing path; determining a second routing path condition indicating a state of the second routing path, in response to the detected reduction in transmission capacity on the first routing path; and deciding upon rerouting one or more of the service tunnels from the first routing path to the second routing path based on both the first routing path condition and the second routing path condition, wherein the rerouting from the first routing path to the second routing path is prevented when the rerouting would not improve one or more transmission rates for the service tunnels, the transmission rates being estimated for a performance expected after the rerouting based on both the first routing path condition and the second routing path condition. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

30. A device for routing one or more service tunnels in a telecommunications backhaul network including a first routing path and a second routing path, the device comprising:
-
a transmitting circuit adapted to transmit data of the one or more service tunnels on the first routing path; a detecting circuit adapted to detect a reduction in transmission capacity on the first routing path by means of a first routing path condition indicating a state of the first routing path; a determining circuit adapted to determine a second routing path condition indicating a state of the second routing path in response to the detected reduction in transmission capacity on the first routing path; and a deciding circuit adapted to decide upon rerouting one or more of the service tunnels from the first routing path to the second routing path based on both the first routing path condition and the second routing path condition, wherein the deciding circuit is further adapted to prevent the rerouting from the first routing path to the second routing path when the rerouting would not improve one or more transmission rates for the service tunnels, the deciding circuit being adapted to estimate the transmission rates for a performance expected after the rerouting based on both the first routing path condition and the second routing path condition. - View Dependent Claims (31)
