A network is programmed to, based on a service function policy, determine a first service function chain of services to apply to outbound packets of a first type that arrive at a serving gateway; upon classifying a first outbound packet arriving at the serving gateway as the first type based on an identifier of the first outbound packet, route the first outbound packet to the services of the first service function chain; map the identifier to the first type such that the mapping is accessible by the packet gateway; determine a second service function chain of the same services to apply to inbound packets of the first type that arrive at a packet gateway; and upon classifying a first inbound packet arriving at the packet gateway as the first type based on the mapped identifier, route the first inbound packet to the services of the second service function chain.

An Encrypted Transport (ET) proxy module is configured to receive incoming ET proxy packets from an ET proxy backbone module and transmit outgoing ET proxy packets to the ET proxy backbone module. The ET proxy module is also configured to set up an HTTP tunnel with an ET proxy client of the client device or with an ET proxy at a web server for receiving incoming UDP payloads from the client device or web server and transmitting outgoing UDP payloads to the client device or web server. The ET proxy module is also configured to receive prioritization preferences from client devices or web servers pertaining to the UDP payloads indicating preferred quality-of-service (QoS) classes for the UDP payloads, and to schedule transmission of the outgoing UDP payloads via the HTTP tunnel based on QoS classes of the outgoing UPD payloads.

Distributed proxy for encrypted transport protocols with efficient multi-priority multiplexed transport for improving user's traffic QOS

An Encrypted Transport Proxy Backbone Protocol module is configured to set up ET Proxy Backbone connections with another distributed proxy device with each ET Proxy Backbone connection including multiple ET Proxy Backbone channels for transmitting ET proxy packets having different QoS classes. Each ET Proxy Backbone channel includes a separate queue. The ET Proxy Backbone Protocol module is also configured to schedule transmissions of the ET proxy packets from each respective queue; multiplex the ET proxy packets from each respective queue via the associated ET Proxy Backbone channel; perform local recovery of network impairments over the access network and perform congestion control to prevent packets from client devices and web servers from causing network congestion to the access network.

A system comprises a gateway computer further comprising a processor and a memory. The memory stores instructions executable by the processor to determine one or more service functions (SF) based on a received data packet, and to determine a list of routing identifiers based on the determined service functions and a destination of the data packet. Each routing identifier identifies at least one of a router computer and a service function. The memory stores instructions to update the data packet to include the list of routing identifiers, and to transmit the updated data packet based on the list of routing identifiers.
