摘要： A method and system for protection switching distributes responsibility for action between a central controller and network elements at endpoints of a linear point-to-point network path. The central controller may be configured to support protection switching by network elements at endpoints of a linear point-to-point path, such that the network elements perform protection switching independently and without direct involvement and/or dependency of the central controller. Simultaneously, the central controller may remain aware of network element actions, events, and states with regard to protection switching, by receiving corresponding notifications from the network elements.

摘要： Methods and structure are provided for implementing security features in SCSI Enclosure Services (SES) systems. The system comprises an SES device server, which includes a frontend interface, control unit, and backend interface. The frontend interface is operable to receive SES commands generated by Small Computer System Interface (SCSI) devices, and the backend interface is operable to manage operations of at least one peripheral device communicatively coupled with the SES device server based on received SES commands. The control unit is operable to determine whether a SCSI initiator that generated an SES command is an authorized device. The control unit is further operable to perform the SES command in response to determining that the SCSI initiator is an authorized device, and is further operable to reject the SES command in response to determining that the SCSI initiator is not an authorized device.
