Abstract

A computer stores packets from a first device at a first buffer. The computer decodes the packets to obtain decoded packets at a decoder. The computer encodes encoding the decoded packets to obtain encoded packets at an encoder. The computer transmits the encoded packets from the encoder to a storage unit. The computer fetches the encoded packets from the storage unit using a second buffer. The computer causes a transmitter to transmit the encoded packets from the second buffer to a second device.

Claims (42)

1 . A server comprising:

processing circuitry and memory hardware, the memory hardware comprising:

a first buffer configured to store packets from a first device;

a decoder configured to decode the packets to obtain decoded packets;

an encoder configured to:

encode the decoded packets to obtain encoded packets, and

transmit the encoded packets to a storage unit; and

a second buffer configured to:

fetch the encoded packets from the storage unit at a first interval, and

cause a transmitter to transmit the encoded packets to a second device at a second interval.

2 . The server of claim 1 , wherein the first buffer stores the packets in a sequential order.

3 . The server of claim 1 , wherein the packets comprise real-time transport protocol (RTP) packets.

4 . The server of claim 1 , wherein an artificial intelligence technique is applied to the encoded packets in the storage unit to identify and remove packets that lack human speech.

5 . The server of claim 1 , wherein the storage unit is a lock-free storage unit.

6 . The server of claim 1 , the memory hardware comprising:

a third buffer, wherein the server is configured to enable the third buffer based on network congestion.

7 . The server of claim 1 , the memory hardware comprising:

a third buffer, wherein the server is configured to enable the third buffer based on a detection of a quality of service (QoS) that is below a threshold QoS.

8 . A method comprising:

decoding packets stored at a first buffer to obtain decoded packets at a decoder;

encoding the decoded packets to obtain encoded packets at an encoder;

fetching the encoded packets at a first interval using a second buffer; and

causing a transmitter to transmit the encoded packets from the second buffer to a device at a second interval.

9 . The method of claim 8 , wherein the first buffer stores the packets in an order based on a sequence.

10 . The method of claim 8 , wherein the packets comprise at least one real-time transport protocol (RTP) packet.

11 . The method of claim 8 , wherein an artificial intelligence technique is applied to the encoded packets to identify and remove packets that lack human speech.

12 . The method of claim 8 , wherein the encoded packets are transmitted to a lock-free storage unit.

13 . The method of claim 8 , comprising:

enabling a third buffer based on network congestion.

14 . The method of claim 8 , comprising:

enabling a third buffer based on a detection of a quality of service (QoS) that is below a threshold QoS.

15 . At least one non-transitory computer readable medium storing instructions operable to cause processing circuitry to perform operations comprising:

decoding packets stored at a first buffer to obtain decoded packets at a decoder;

encoding the decoded packets to obtain encoded packets at an encoder;

fetching the encoded packets at a first interval using a second buffer; and

causing a transmitter to transmit the encoded packets from the second buffer to a device at a second interval.

16 . The at least one computer readable medium of claim 15 , wherein the first buffer stores the packets in accordance with a sequence.

17 . The at least one computer readable medium of claim 15 , wherein the packets comprise one or more real-time transport protocol (RTP) packets.

18 . The at least one computer readable medium of claim 15 , wherein an artificial intelligence technique is applied to the encoded packets to identify and remove packets that lack human speech.

19 . The at least one computer readable medium of claim 15 , wherein the encoded packets are transmitted to a lock-free storage unit.

20 . The at least one computer readable medium of claim 15 , the operations comprising:

enabling a third buffer based on at least one of: a detected network congestion or a detected quality of service (QoS) that is below a threshold QoS.
