Voice over internet protocol multi-routing with packet interleaving
A method and system for processing data packets is described within. The method executed by the system includes the steps of receiving a first data packet, determining if the first data packet is a first expected data packet, determining if the first data packet is a next expected date packet, storing the first data patent if the first data packet is the next expected data packet and waiting a period of time for a second data packet.
1. A method for processing data packets having a first data packet and a second data packet, comprising:
receiving, via a processor, the first data packet from one of: a first data stream on a first communication path of a network and a second data stream on a second communication path of the network, the first and second data streams comprising a plurality of data packets, the plurality of data packets of the second data stream being a duplicate of the plurality of data packets of the first data stream;
determining, via the processor, whether the first data packet is a first expected data packet or a next expected data packet;
storing, via the processor, the first data packet in a memory unit when the first data packet is the next expected data packet; and
waiting, via the processor, a period of time for the second data packet from one of: the first data stream and the second data stream.
2. The method of claim 1 , wherein the determining whether the first data packet is the first expected data packet or the next expected data packet comprises:
comparing a packet sequence number of the first packet to an expected data packet sequence number.
3. The method of claim 2 , wherein the packet sequence number comprises a real-time transfer protocol data packet sequence number.
4. The method of claim 1 , wherein when the second data packet is not received within the period of time, the first data packet is discarded from the memory unit.
5. The method of claim 4 , wherein the period of time is about 30milliseconds.
6. The method of claim 1 , wherein the first communication path and the second communication path are determined via two different routing tables.
7. The method of claim 1 , wherein the processor is deployed within a router.
8. A non-transitory computer readable medium storing a computer program which, when executed by a processor, causes the processor to perform operations for processing data packets having a first data packet and a second data packet, the operations comprising:
receiving the first data packet from one of: a first data stream on a first communication path of a network and a second data stream on a second communication path of the network, the first and second data streams comprising a plurality of data packets, the plurality of data packets of the second data stream being a duplicate of the plurality of data packets of the first data stream;
determining whether the first data packet is a first expected data packet or a next expected data packet;
storing the first data packet in a memory unit when the first data packet is the next expected data packet; and
waiting a period of time for the second data packet from one of: the first data stream and the second data stream.
9. The non-transitory computer readable medium of claim 8 , wherein the determining whether the first data packet is the first expected data packet or the next expected data packet comprises:
comparing a packet sequence number of the first packet to an expected data packet sequence number.
10. The non-transitory computer readable medium of claim 9 , wherein the packet sequence number comprises a real-time transfer protocol data packet sequence number.
11. The non-transitory computer readable medium of claim 8 , wherein when the second data packet is not received within the period of time, the first data packet is discarded from the memory unit.
12. The non-transitory computer readable medium of claim 11 , wherein the period of time is about 30 milliseconds.
13. The non-transitory computer readable medium of claim 8 , wherein the first communication path and the second communication path are determined via two different routing tables.
14. The non-transitory computer readable medium of claim 8 , wherein the processor is deployed within a router.
15. A system for processing data packets having a first data packet and a second data packet, the system comprising:
a processor; and
a computer-readable medium storing a plurality of instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising:
receiving the first data packet from one of: a first data stream on a first communication path of a network and a second data stream on a second communication path of the network, the first and second data streams comprising a plurality of data packets, the plurality of data packets of the second data stream being a duplicate of the plurality of data packets of the first data stream;
determining whether the first data packet is a first expected data packet or a next expected data packet;
storing the first data packet in a memory unit when the first data packet is the next expected data packet; and
waiting a period of time for the second data packet from one of: the first data stream and the second data stream.
16. The system of claim 15 , wherein the determining whether the first data packet is the first expected data packet or the next expected data packet comprises:
comparing a packet sequence number of the first packet to an expected data packet sequence number.
17. The system of claim 16 , wherein the packet sequence number comprises a real-time transfer protocol data packet sequence number.
18. The system of claim 15 , wherein when the second data packet is not received within the period of time, the first data packet is discarded from the memory unit.
19. The system of claim 18 , wherein the period of time is about 30milliseconds.
20. The system of claim 15 , wherein the first communication path and the second communication path are determined via two different routing tables.
