Zusammenfassung:PROBLEM TO BE SOLVED: To provide a technology of facilitating construction of an application, service and system using peer-to-peer communication.SOLUTION: A communication apparatus that executes peer-to-peer communication by use of WebRTC (Web Real-Time Communication) via a STUN server managed by a network provider, a TURN server, and an authentication server includes: an authentication function of managing an authentication key issued by the authentication server which has been allowed to access the STUN server and the TURN server; and an ICE function of acquiring an IP address for the peer-to-peer communication by executing ICE (Interactive Connectivity Establishment) for passing through an NAT/FW (Network Address Translation/Firewall) mounted on the WebRTC. 【課題】ピアツーピア通信を伴うアプリケーション、サービス、システム等の構築を容易にするための技術を提供する。【解決手段】ネットワーク事業者により運営されるSTUNサーバ、TURNサーバ及び認証サーバを介しWebRTC(Web Real-Time Communication)を利用してピアツーピア通信を実行する通信装置であって、STUNサーバ及びTURNサーバにアクセス可能であると判断した前記認証サーバにより発行された認証キーを管理する認証機能と、前記WebRTCに実装されたNAT/FW(Network Address Translation/Firewall)を通過するためのICE(Interactive Connectivity Establishment)を実行することによって、前記ピアツーピア通信のためのIPアドレスを取得するICE機能とを有する。【選択図】図1
