Data network for monitoring animals
The invention relates to a data network for automatically monitoring voluntary behaviors of individual animals of an animal herd. The individual animals of the animal herd each have a node of the data network. A further node is attached at a location which an animal preferably approaches in the course of a behavior to be monitored. In the event that the animal approaches the node, communication occurs between the nodes, in which communication one node is identified by the other node and a central data-processing system is informed that the two nodes have come into contact. The communication between the two nodes occurs by means of the transfer of electrical signals in a closed electrical alternating-current circuit, which also passes, among other things, through the body of the animal as an electrical conductor. |

Method and apparatus for displaying terminal in single base station in wireless communication system
The present specification proposes a method of displaying a terminal involved in public disaster safety communication in a single base station that has a constraint on a normal backhaul connection. Even when the backhaul connection is disconnected, it is possible for a terminal to communicate by using an X2 connection between base stations, but there is a limitation in that it is difficult for a terminal to find the position of another terminal because a connection between the base station and an evolved packet core (EPC) is disconnected. Thus, there is a need for a method to solve this limitation. Whether there is a backhaul connection between a first base station and the EPC is detected, and when a backhaul connection is not detected, a first ID is allocated to a terminal in the service area of the first base station and the first ID allocated is transmitted to a second base station. When there is a backhaul connection between the first base station and the EPC, a globally unique temporary identifier (GUTI) of the terminal in the service area of the first base station is received from a mobility management entity (MME). Then, whether there is a backhaul connection between the first base station and the EPC is detected, and when a backhaul connection is not detected, the GUTI of the terminal in the service area of the first base station is transmitted to the second base station. |

Optimizing EVPN for data centers with redundant top-of-rack deployments
Presented herein are methods for advertising an IP prefix to address the connectivity problem in multi-chassis link aggregation scenario. A peer switch will advertise two VTEP addresses. It will use a physical IP (PIP) address as a next hop (NH) for a prefix route, while continuing to use a VIP for host IP and MAC route advertisement. A new virtual MAC is introduced and it is derived from the VIP as the router MAC associated with VIP. A switch is made to use a VIP for prefix advertisement when a device detects that the same prefix is reachable both locally and from its peer. This saves adjacency entries consumed in the remote VTEPs. These techniques fix the connectivity issue for prefix routes that is exposed with current EVPN, without requiring any additional adjacency resource consumption. |
