Abstract: An apparatus for detecting a loop in a domain comprising a plurality of overlay tunnel fabrics is provided. The apparatus can include an indicator logic block that can insert a predetermined value, which can be unique for the apparatus in the domain, into an egress tunnel header of a packet of a data flow.

Abstract: A continuity checking apparatus generates a continuity checking packet to which a predetermined flag and user attributes are assigned and transmits the generated continuity checking packet to an edge router connected to a service that is an entrance of a service chain. Each service transmits an arrival message with respect to the continuity checking packet to the continuity checking apparatus upon reception of the continuity checking packet to which the predetermined flag is assigned. In addition, each service transfers the continuity checking packet to a next service device of the service chain on the basis of the user attributes assigned to the received continuity checking packet. The continuity checking apparatus identifies a path representing service devices through which the continuity checking packet passes on the basis of the arrival message transmitted from each service, and determines whether the identified path is the same as a path of the service chain that is a continuity checking target.

Abstract: A computer-implemented method for operating in a reduced power mode (RPM) of a user equipment (UE) in communications with a base station pursusant to a normal power mode (NPM). The NPM is characterized by one or more normal-power parameters comprising a normal sampling frequency and a normal signal bandwidth. The RPM is characterized by one or more reduced-power parameters comprising a reduced sampling frequency or a partial signal bandwidth. The UE determines whether to enter into the RPM for a duration. In response to determining to enter into the RPM for the duration, the UE powers down into the RPM by operating with the one or more reduced-power parameters for the duration of the RPM. Upon expiry of the duration of the RPM by the UE, the UE powers up into the NPM by resuming to the sampling frequency of the NPM and the signal bandwidth of the NPM.
