Abstract
(EN)
Virtual application and desktop delivery may be optimized by supplying application metadata and user intent to the device between a client and a server hosting resources for the delivery. The data packets used to deliver the virtual application or desktop may be also tagged with references to the application. By supplying the metadata and tagging packets with the metadata, an intermediary network device may provide streams of data packets at the target QoS. In addition, the device may apply network resource allocation rules (e.g., firewalls and QoS configuration) for redirected content retrieved by the client out of band relative to a virtual channel such as the Internet. The network resource allocation rules may differ for different types of resources accessed. The device may also control a delivery agent on the server to modify communication sessions established through the virtual channels based on network conditions.

Une fourniture d'application et de bureau virtuels peut être optimisée en fournissant des métadonnées d'application et une intention d'utilisateur au dispositif entre un client et un serveur hébergeant des ressources pour la distribution. Les paquets de données utilisés pour distribuer l'application virtuelle ou le bureau virtuel peuvent également être étiquetés avec des références à l'application. En fournissant les métadonnées et en étiquetant des paquets avec les métadonnées, un dispositif de réseau intermédiaire peut fournir des flux de paquets de données à la QoS cible. De plus, le dispositif peut appliquer des règles d'attribution de ressources de réseau (par exemple, des pare-feu et une configuration QoS) pour un contenu redirigé récupéré par le client hors bande par rapport à un canal virtuel tel que l'internet. Les règles d'attribution de ressources de réseau peuvent différer pour différents types de ressources faisant l'objet d'un accès. Le dispositif peut également commander un agent de distribution sur le serveur pour modifier des sessions de communication établies à travers les canaux virtuels sur la base de conditions de réseau.
