Abstract
Particular embodiments provide an N+0 sharing scheme for networks. The N+0 sharing scheme includes no dedicated spare among a group of active elements. Each active element may provide service to a medium, which may be associated with a medium. When a failure to one of the active elements occurs, at least one of the working active elements takes the workload of the failed active element. The cost of N+0 sharing is a reduced per medium (e.g., service group) capacity during a failure. That is, some service groups may receive less bandwidth from the active element that is used in the sharing scheme to compensate for the failure. However, this may be preferable to service operators compared to the additional cost of including a spare for the group of active elements, or the complete loss of service that occurs when a failure occurs without a failure recovery scheme.
