Abstract: At a network device through which client devices communicate with a network, a database is created that maps Internet Protocol (IP) addresses each to a respective trust metric for a domain name associated with the IP address. An IP packet sent from a client device to the network and that indicates a destination IP address for a network-accessible resource associated with a domain name is intercepted. Using the destination IP address in the intercepted IP packet, the domain name trust metric mapped to the destination IP address is retrieved from the database. IP packets received from the destination IP address are processed based on the retrieved domain name trust metric and a predetermined trust metric criterion.

Abstract: A system includes a media optimizer that adaptively generates and transmits a modified manifest file based on an original manifest file corresponding to an associated media asset from a content provider in response to a media content request from a client for the associated media asset. The original manifest file specifies bitrates. The media optimizer extracts parameters associated with the media content request and applies bitrate policies based on the extracted parameters to adaptively modify the original manifest file to generate the modified manifest file. The media optimizer is further configured to transmit the modified manifest file to the client for selection by the client of a bitrate associated with delivery of the associated media asset.

Abstract translation: 在客户端设备通过网络与网络进行通信的网络设备上，创建将互联网协议（IP）地址分别映射到与IP地址相关联的域名的相应信任度量的数据库。 从客户端设备发送到网络并且指示与域名相关联的网络可访问资源的目的地IP地址的IP分组被截获。 在拦截的IP包中使用目的地IP地址，从数据库中检索映射到目标IP地址的域名信任度量。 基于检索到的域名信任度量和预定的信任度量标准来处理从目的地IP地址接收到的IP分组。

Abstract translation: 系统包括媒体优化器，其响应于来自客户端的关联媒体资产的媒体内容请求，基于来自内容提供商的对应于相关联的媒体资产的原始清单文件自适应地生成和发送修改的清单文件。 原始清单文件指定比特率。 媒体优化器提取与媒体内容请求相关联的参数，并且基于所提取的参数应用比特率策略，以自适应地修改原始清单文件以生成修改的清单文件。 媒体优化器还被配置为将修改的清单文件发送到客户端以供客户选择与相关联的媒体资产的递送相关联的比特率。
