Content Based Routing with High Assurance MLS (multi-level security) methods and systems are described. In an embodiment, a security component receives content from a content provider. The security component can identify a security level of content metadata located within the content received from the content provider. A content router can receive a content descriptor from the content provider and an interest profile from a requesting system. The content router can utilize algorithms to create routing tables based on metadata in the content descriptor, and the interest profile. The content router can provide the content metadata to the requesting system based on the interest profile. A content filter can filter or sanitize the content metadata according to a security level of the requesting system before providing the content metadata to the requesting system.

L'invention concerne un système d'acheminement à base de contenu qui est capable d'acheminer un contenu qui est contenu dans des paquets de données selon des métadonnées de contenu situées dans le contenu respectif. Le routeur de contenu reçoit un descripteur de contenu du fournisseur et un profil d'intérêt du système demandeur. Sur la base des métadonnées dans les descripteurs de contenu et du profil d'intérêt, le routeur de contenu crée des tables d'acheminement et fournit les métadonnées de contenu au système demandeur sur la base du profil d'intérêt. Les métadonnées de contenu sont filtrées ou nettoyées en fonction d'un niveau de sécurité du système demandeur avant que les métadonnées de contenu ne soient fournies au système demandeur.
