DISTRIBUTED COMPUTING SERVICE PLATFORM FOR MOBILE NETWORK TRAFFIC

摘要

Described herein are systems, methods, and apparatus for processing network packet data in a distributed computing platform, such as a content delivery network, to provide services to mobile network operators and/or their mobile subscribers. According to the teachings hereof, distributed computing resources can be organized into a service platform to provide certain value-add services—such as deep packet inspection, transcoding, lawful intercept, or otherwise—using a service function chaining model. The platform resources are preferably located external to the mobile network, on the public Internet. The platform preferably operates on and processes traffic entering or exiting the mobile network. In some embodiments, the service platform is able to establish an encrypted channel between itself and the mobile client through the mobile network, e.g., using content provider key and certificate information available to the platform (but which may not be available to the mobile network operator).

主权项

1. A method of processing packets in a distributed computing platform, the method performed by servers in the distributed computing platform, the method comprising:
establishing an encrypted session between a server in a distributed computing platform and a mobile client device connected to a mobile network, the server being external to the mobile network; as part of the encrypted session, receiving one or more packets from the mobile client device via a mobile network gateway; decrypting the one or more packets; processing data from the one or more packets in a service function chain made of two or more service functions, the processing occurring at one or more servers that provide the service function chain in the distributed computing platform; sending the processed data from the one or more packets to any of: (i) the mobile client device, via the mobile network gateway and (ii) an origin server that is external to the mobile network and is associated with a content provider.
