METHOD AND NETWORK FOR COMBINED PROTECTION OF ETHERNET TRAFFIC
First Claim
1. A method for protecting different telecommunication services in an Ethernet network using at least two different loop avoiding traffic protection protocols, by concurrently utilizing two of said protocols in one and the same network on different loop free logical topologies of the network, wherein said telecommunication services are preliminarily distributed in such a manner, that the services appropriately protectable by one of the two protocols and the services appropriately protectable by the other of the two protocols are respectively carried via the different loop free logical topologies.

Abstract
Technique for protecting different telecommunication services in an Ethernet network using two different loop avoiding traffic protection protocols, by concurrently utilizing the protocols in one and the same network on different loop free logical topologies of the network. The telecommunication services are preliminarily distributed in such a manner, that the services which can be better protected by one of the two protocols and the services better protectable by the other protocol, are carried via the different topologies.

7. A method for protecting two different groups of different telecommunication services in one Ethernet network by two different loop avoiding protection protocols, comprising:
-
dividing the network into at least two loop-free logical topologies respectively assigned to the two different groups of telecommunication services and to the two different protection protocols, selectively applying, at ports of an Ethernet node in the network, one or another of the two different protocols, depending on the group of the telecommunication service being handled, and ensuring that ports of an Ethernet node in the network are adapted to independently forward and process signaling messages of any one of said two protocols.

8. An Ethernet network, wherein two different loop avoiding traffic protection protocols are applicable concurrently to different logical topologies of the network and to different telecommunication services handled at one and the same network node, while to a specific telecommunication service being handled at said node, applicable is a specific one from said two protocols, depending on said specific service.
- 9. A node for operating at an Ethernet network, being provided with a double-protocol block for concurrently applying two loop avoiding traffic protection protocols to different telecommunication services handled by the node and belonging to one or another of two different groups, wherein said block being adapted to selectively apply one or another protocol to a telecommunication service being handled at the node, depending on the group to which said telecommunication service belongs.
