1e41f4b71Sopenharmony_ci# Introduction to Distributed Service Kit 2e41f4b71Sopenharmony_ci 3e41f4b71Sopenharmony_ciDistributed Service Kit implements distributed device management, distributed hardware management, and distributed keyboard and mouse traversal. 4e41f4b71Sopenharmony_ci 5e41f4b71Sopenharmony_ciDistributed services are underpinned by distributed device management, which involves discovering and authenticating nearby devices, querying device information, and listening for device status. That is, distributed services can be performed only between authenticated devices. 6e41f4b71Sopenharmony_ci 7e41f4b71Sopenharmony_ci## Working Principles 8e41f4b71Sopenharmony_ci 9e41f4b71Sopenharmony_ciThe application is required to initiate a request for device discovery, authentication, query, and listening. 10e41f4b71Sopenharmony_ci 11e41f4b71Sopenharmony_ci## Constraints 12e41f4b71Sopenharmony_ci 13e41f4b71Sopenharmony_ciThe application needs user authorization before implementing distributed device management. 14
