摘要： Provided are a method and apparatus for ensuring a cleaning robot to return to a charge station. The method includes the steps of: (a) measuring a battery usable time, a running speed, and an actual return distance of a cleaning robot during a cleaning operation; (b) calculating an allowable return distance on the basis of the battery usable time and the running speed; (c) comparing the actual return distance with the allowable return distance; and (d) returning the cleaning robot to the charge station when the actual return distance is larger than the allowable return distance as a result of the comparison. Therefore, it is possible to prevent the cleaning robot from being not returned to the charge station, thereby providing convenience to a user.

摘要： Disclosed are an apparatus and a method for swapping headers for authenticating policy based domains and tracing paths at the time of high-reliable data plane transmission. The method includes receiving packets forwarded through predetermined paths, confirming whether the received packets are normal packets, determining whether the path identification information corresponding to the paths of the received packets is present in a header information storage unit of a domain receiving the packets, swapping the headers included in the packets to swapping headers of the header information storage unit by using the identification information if it is determined that the path identification information is present, and correcting the path tracing information. By this configuration, degradation in data plane performance due to the lengths of headers can be solved.

摘要： Provided is a multi-layer restoration method using a LCAS (Link Capacity Adjustment Scheme) in a synchronous network having a mesh structure. The method includes: performing a hardware restoration method if a network failure is detected; performing a pre-planned restoration method if the network failure is not repaired by performing the hardware restoration method; determining whether channels that pass along a line where the network failure occurs use the LCAS if the network failure is not repaired by performing the pre-planned restoration method; and applying the LCAS to the channels if the channels are determined to use the LCAS, and performing a dynamic restoration method if the channels are not determined to use the LCAS. The multiplayer restoration method minimizes data loss due to an increase in restoration time and overcomes service disconnection caused by failure to obtain a spare channel.
