    Abstract: In one embodiment, a service function classifier device determines a classification of a packet using one or more packet classification rules. The device selects a service function path based on the classification of the packet. The device determines one or more traffic flow characteristics based on the classification of the packet. The device generates a service function chaining (SFC) header that identifies the selected service function path and the determined one or more traffic flow characteristics. The SFC header is configured to cause a device along the service function path to forward the encapsulated packet based on the identified service function path and the determined one or more traffic flow characteristics. The device sends the packet along the selected service function path as an encapsulated packet that includes the generated SFC header.

    Abstract: In one embodiment, first content is served by an application server to a client computer through an Internet service provider network. The first content includes a link to second content on a third-party server. A token request is sent from the third-party server to the application server in response to selection of the link by the client computer. A token is provided to the third-party server by the application server in response to the token request. The token is configured to authorize data flow at a bandwidth for the second content by the Internet service provider network to the client computer. The data flow is authorized based on an agreement for the bandwidth between an operator of the application server and an operator of the Internet service provider network.

    Abstract: A first service node receives a message configured to set up a secure communication session between a client and a server, in which the first service node acts as a proxy. Data packets in the secure communication session are subject to multiple service functions that require decryption of the data packets. A service function chain assigns a service node to each of the service functions. A service header is generated including metadata instructing the service nodes other than the first service node not to act as proxies in the secure communication session. The message and the service header are transmitted to a second service node in the service function chain.

    Abstract: In one implementation, a media stream is recorded using one or more keys. The one or more keys are also encrypted. The one or more encrypted keys may be stored with the encrypted media session at a cloud storage service. A network device receives a request to record a media stream and accesses at least one stream key for the media stream. The stream key is for encrypting the media stream. The network device encrypts the stream key with a master key. The encrypted stream key is stored in association with the encrypted media stream.

    Abstract: Various embodiments are disclosed for prioritizing network flows and providing differentiated quality of service in a telecommunications network. In some embodiments, a SecaaS can be utilized to signal flow characteristics of one or more network flows to a connector in a network so that the network can install differentiated quality of service against the one or more network flows based upon the received flow characteristics. Some embodiments enable a connector in a network to act as a PCP client to signal received flow characteristics to an upstream PCP server hosted by an adjacent access network.

    Abstract: In one implementation, traffic in a mobile network is directed across multiple paths to a single cloud server or security server (e.g., a security as a service). The mobile device detects a cloud connector through a primary connection based on an attachment or connection via a first interface of a mobile device. The mobile device sends a request to the cloud connector for an identification of a cloud security server associated with the cloud connector. After receiving the identification of the cloud security server, the mobile device directs one or more subsequent data flows or subflows for a second interface or another interface of the mobile device to the cloud server or security server. The second data flow and the second interface are associated with another network that is external to the enterprise network and trusted network connection or not associated with the enterprise network and the trusted network connection.

    Abstract: In one implementation, downloading of streaming content using a security as a service (SecaaS) system is more efficient because portions of the streaming content may not be inspected by the SecaaS. A first request to download content from a content provider is received, and a connection is initiated with a security provider, which inspects the first chunk of the content and generates a routing instruction based on the inspection of the first chunk of content. Based on the routing instructions and the inspection of the first chunk, a request for a second chunk of the streaming content is addressed to the content provider. The second chunk of the streaming content, circumvents the SecaaS system.

    Abstract translation: 在一个实现中，使用安全即服务（SecaaS）系统下载流内容更为有效，因为部分流媒体内容可能不被SecaaS检查。 接收到从内容提供商下载内容的第一请求，并且与安全提供者发起连接，安全提供者检查内容的第一块，并且基于第一内容块的检查来生成路由指令。 基于路由指令和对第一块的检查，流式传输内容的第二块的请求被寻址到内容提供商。 流媒体内容的第二大部分规避了SecaaS系统。
