IP ネットワークはユーザ ・ サーバ間通信を基本とし，サーバに負担が集中する問題がある．加えて，IP ルータはユーザから受け取ったパケットを次のルータに横流しするだけであり，ルータは，ユーザが必要とするコンテンツを提供する機能を有していない．従来の転送機能に加え，キャッシュ機能を持つよう機能拡張されたルータにより構築されるネットワークが CCN (Content Centric Networking) であり，次世代ネットワークとして注目されている．CCN ルータは，FIB と呼ばれるルーティングテーブルを持つが，FIB のテーブルルックアップにかかる比較数がボトルネックとなる．本稿では，分割ハシシュテーブルと平衡木を組み合わせたデータ構造を持つ FIB を提案する．提案手法は，ハシシュによるテーブル探索を基本とし，ハシシュ値が衝突した際に，平衡木を用いてデータを保持する．ハッシュによるテーブル探索の前処理としてブルームフィルタによるフィルタリングを行い， さらに， コンテンツのネーム長が 4 以下のコンテンツ名によるハッシュ値とコンテンツのネーム長が 5 以上のコンテンツ名によるハシシュ値の 2 つに分けて考えることで，ハッシュテーブルを分割する． フィルタリングと分割ハッシュテーブルを用いることで平衡木の高さを小さくし，比較数を削減できる．提案手法の比較数は，多分木で実装した FIB に比べ約 92.5 ％，ハッシュテーブル (線形リスト) で実装した FIB に比べ約 40.7 % ，ハシシュテーブル (平衡木) で実装した FIB に比べ約 18.5 % ，ブルームフイルタ ＋ ハッシュテーブル (線形リスト) で実装した FIB に比べ約 31.1 %，ブルームフイルタ ＋ ハッシュテーブル (平衡木 ＋ 分割なし) で実装した FIB に比べ約 5.14 %
