PCC sends at a rate r for a short period of time, and observes the results (e.g. SACKs indicating delivery, loss, and latency of each packet). Instead of triggering control responses immediately, it aggregates these packet-level events into a utility function that describes an objective like 'high throughput and low loss.

- Token-Limited Congestion Control (STLCC) is introduced as new protocols which appends inter-domain congestion control to TBCC and make the congestion control system to be stable. STLCC is able to shape output and input traffic at the inter-domain link with O(1) complexity. STLCC produces a congestion index, pushes the packet loss to the network.

Packet loss concealment (PLC) is a technique to mask the effects of packet loss in voice over IP (VoIP) communications. When the voice signal is sent as VoIP packets on an IP network, the packets may (and likely will) travel different routes. A packet therefore might arrive very late, might be corrupted, or simply might not arrive at all. One example case of the last situation could be, when a packet is rejected by a server which has a full buffer and cannot accept any more data. Other cases include network congestion resulting in significant delay. In a VoIP connection, error-control techniques such as automatic repeat request (ARQ) are not feasible and the receiver should be able to cope with packet loss. Packet loss concealment is the inclusion in a design of methodologies for accounting for and compensating for the loss of voice packets.
PLC techniques[edit]
- Zero insertion: the lost speech frames are replaced with zero
- Waveform substitution: the missing gap is reconstructed by repeating a portion of already received speech. The simplest form of this would be to repeat the last received frame. Other techniques account for fundamental frequency, gap duration etc. Waveform substitution methods are popular because of their simplicity to understand and implement. An example of such an algorithm is proposed in International Telecommunication Union (ITU) recommendation G.711 Appendix I.
- Model-based methods: an increasing number of algorithms that take advantage of speech models of interpolating and extrapolating speech gaps are being introduced and developed.
Use[edit]
PLC is used with the codecs Internet Low Bitrate Codec (iLBC)[1][2] and SILK[3] in Skype, in Jitsi with the SILK and Opus codecs,[4][5] and in the pjsip stack used by CSipSimple.[6]Google Duo uses WaveNetEQ, a generative model based on DeepMind/Google AI’s WaveRNN.[7]
