segment routing，network service header に代表される要素技術をもとに最短経路に基づかない end-to-end の通信路をプログラマブルに構成するトラフィック ・ エンジニアリング (TE) 手法の開発が盛んである．しかし，これらの TE 手法では network service provider (core entity) と application service provider (end entity) 間でのセマンティクスの共有がなされず，core entity は endentity のセマンティクスに基づかない通信路しか形成できない．また end entity による通信路構築が適切かを core entity で検証する機構も存在しない．本稿では，インターネットに代表される Open Network 環境を対象とする，core entity と end entity との間でのセマンティクス共有を前提としたTE手法を提案する．共通のセマンティクス理解する entity 群は closed な overlay network (vAS: virtualized autonomoussystem) に属する．vAS では end entity と core entity の双方のセマンティクスを考慮した end-to-end の通信路が構成され，その通信路に従ってパケットは転送される．vAS 上でのパケット転送は既存の OpenNetwork 環境のパケット転送に failover 可能なので，end-to-end
