Claim Text:
1. A distributed radio access network, arranged for communicatively coupling to a core network, the distributed radio access network comprising: a main radio equipment controller communicatively coupled to at least one remote radio unit over a main optical path; a backup radio equipment controller communicatively coupled to the main radio equipment controller for synchronization; and a protection optical path for communicatively coupling the at least one remote radio unit to the backup radio equipment controller in case of a failure in communication between the main radio equipment controller and the at least one remote radio unit over the main optical path, such that a service remains running when the failure occurs wherein the protection optical path is longer than the main optical path and comprises a transmission capacity which is smaller than a transmission capacity over the main optical path such that in case of the failure in communication over the main optical path the backup radio equipment controller is configured to negotiate with the at least one remote radio unit a reduction in at least one out of a plurality of predefined parameters.
