Packet retransmission
View Patent ↗Through the identification of different packet-types, packets can be handled based on an assigned packet handling identifier. This identifier can, for example, enable forwarding of latency-sensitive packets without delay and allow error-sensitive packets to be stored for possible retransmission. In another embodiment, and optionally in conjunction with retransmission protocols including a packet handling identifier, a memory used for retransmission of packets can be shared with other transceiver functionality such as, coding, decoding, interleaving, deinterleaving, error correction, and the like.
1. A method of packet retransmission comprising:
transmitting or receiving, using a transceiver, a plurality of packets;
identifying at least one packet of the plurality of packets as a packet that should be retransmitted;
allocating a memory between a retransmission function and an interleaving and/or deinterleaving function; and
transmitting or receiving a message during initialization, wherein the message indicates how the memory is to be allocated between the retransmission function and the interleaving and/or deinterleaving function, and wherein at least a portion of the memory may be allocated to the retransmission function or the interleaving and/or deinterleaving function at any one particular time.
2. The method of claim 1 , wherein the packets are used for video applications.
3. The method of claim 1 , wherein the packets are used for internet access applications.
4. The method of claim 1 , wherein the packets are used for voice applications.
5. The method of claim 1 , wherein the transceiver contains at least one ASIC.
6. The method of claim 1 , wherein the transceiver contains at least one DSP.
7. The transceiver of claim 1 , wherein the transceiver is located on a linecard that is transporting video, internet access and voice data.
8. The transceiver of claim 1 , wherein the transceiver is located in a customer premises equipment that is transporting video, internet access and voice data.
9. The transceiver of claim 1 , wherein a sum of a maximum amount of the memory that can be allocated to the retransmission function and a maximum amount of the memory that can be allocated to the interleaving and/or deinterleaving function is more than a total amount of the memory.
10. A transceiver capable of packet retransmission comprising:
a transmitter portion capable of: transmitting a plurality of packets, identifying at least one packet of the plurality of packets as a packet that should be retransmitted and allocating a memory between a retransmission function and an interleaving and/or deinterleaving function, wherein at least a portion of the memory may be allocated to the retransmission function or to the interleaving and/or deinterleaving function at any one particular time, and wherein a message transmitted during initialization indicates how the memory has been allocated between the retransmission function and the interleaving and/or deinterleaving function in the transceiver.
11. The transceiver of claim 10 , wherein the packets are used for video applications.
12. The transceiver of claim 10 , wherein the packets are used for internet access applications.
13. The transceiver of claim 10 , wherein the packets are used for voice applications.
14. The transceiver of claim 10 , wherein the transceiver contains at least one ASIC.
15. The transceiver of claim 10 , wherein the transceiver contains at least one DSP.
16. The transceiver of claim 10 , wherein the transceiver is located on a linecard that is capable of transporting video, internet access and voice data.
17. The transceiver of claim 10 , wherein a sum of a maximum amount of the memory that can be allocated to the retransmission function and a maximum amount of the memory that can be allocated to the interleaving/deinterleaving function is more than a total amount of the memory.
18. A transceiver capable of packet retransmission comprising:
a receiver portion capable of: receiving a plurality of packets, identifying at least one packet of the plurality of packets as a packet that should be retransmitted and allocating a memory between a retransmission function and an interleaving and/or deinterleaving function
wherein the memory is allocated between the interleaving function and the deinterleaving function in accordance with a message received during an initialization of the transceiver and wherein at least a portion of the memory may be allocated between the retransmission function and the interleaving and/or deinterleaving function at any one particular time depending on the message.
19. The transceiver apparatus of claim 18 , wherein the packets are used for video applications.
20. The transceiver of claim 18 , wherein the packets are used for internet access applications.
21. The transceiver of claim 18 , wherein the packets are used for voice applications.
22. The transceiver of claim 18 , wherein the transceiver contains at least one ASIC.
23. The transceiver of claim 18 , wherein the transceiver contains at least one DSP.
24. The transceiver of claim 18 , wherein the transceiver is located in a customer premises equipment that is capable of transporting video, internet access and voice data.
25. The transceiver of claim 18 , wherein a sum of a maximum amount of the memory that can be allocated to the retransmission function and a maximum amount of the memory that can be allocated to the interleaving and/or deinterleaving function is more than a total amount of the memory.
