Abstract: Embodiments are directed to receiving an original packet at a service function; determining, for a reverse packet, a reverse service path identifier for a previous hop on a service function chain; determining, for the reverse packet, a service index for the reverse service path identifier; and transmitting the reverse packet to the previous hop on the service function chain.

Abstract: Network operators are striving to find ways to provide stable video services amid a rapid increase in video traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes using a content adaptation engine (CAE). However, network operators failed to efficiently readdress video flows to CAEs. This disclosure provides systems and methods for efficiently readdressing video flows to CAEs.

Abstract: Multi-tier recording to enable, for example, seek-back unique copy recording may be provided. First, content may be recorded to a time-shift buffer. Recording instructions may be received and a virtual recorder corresponding to a user may be instantiated. Next, content from the time-shift buffer may be obtained according to the received recording instructions. Then the obtained content may be saved to the instantiated virtual recorder.
