Systems, apparatuses and methods for network packet management
Methods and systems are provided for latency-oriented router. An incoming packet is received on a first interface. The type of the incoming packet is determined. Upon the detection that the incoming packet belongs to latency-critical traffic, the incoming packet is duplicated into one or more copies. Subsequently, the duplicated copies are sent to a second interface in a delayed fashion where the duplicated copies are spread over a time period. The duplicated copies are received and processed at the second interface.
1. A method of managing packets comprising:
receiving, by a routing device, a plurality of packets from a source device associated with a latency-critical session, wherein each packet comprises a packet identifier field including a packet identifier value;
storing, by the routing device, in a memory one or more data structures indicating a last-packet-received value and at least one missing-packet value, wherein the at least one missing-packet value represents a packet identifier value of at least one packet associated with the latency-critical session that has not yet been received by the routing device from the source device, and wherein the at least one missing-packet value is less than the last-packet-received value;
identifying, by the routing device, a first packet identifier value of a next packet of the plurality of packets from the source device associated with the latency-critical session;
transmitting, by the routing device, the next packet to a client device based on determining that the first packet identifier value is greater than the last-packet-received value or that the first packet identifier value is the same as one of the at least one missing-packet value; and
responsive to determining that the first packet identifier value is the same as the one of the at least one missing-packet value, modifying the one or more data structures to indicate that the one of the at least one missing-packet value was received.
2. The method of claim 1 , wherein upon determining that the first packet identifier value is greater than the last-packet-received value, the method further comprising updating the last-packet-received value in the one or more data structures to reflect the first packet identifier value.
3. The method of claim 1 , wherein the one or more data structures is selected from the group comprising: a file, an array, and a list.
4. The method of claim 1 , wherein modifying the data structure comprises deleting the one of the at least one missing-packet value from the one or more data structures.
5. The method of claim 1 , wherein the one or more data structures comprises a bitmask.
6. The method of claim 5 , wherein modifying the one or more data structures comprises changing the bitmask to indicate that the one of the at least one missing-packet value was received.
7. The method of claim 1 , the method further comprising:
receiving, by the routing device, at least one packet from the client device associated with the latency-critical session;
generating, by the routing device, at least one copy-packet of the at least one packet from the client device associated with the latency-critical session; and
transmitting, by the routing device, the at least one packet and the at least one copy-packet to the source device.
8. A routing device comprising:
an interface;
a machine-readable memory; and
a processor configured to:
receive a plurality of packets from a source device associated with a latency-critical session, wherein each packet comprises a packet identifier field including a packet identifier value;
store in the machine-readable memory one or more data structures indicating a last-packet-received value and at least one missing-packet value, wherein the at least one missing-packet value represents a packet identifier value of at least one packet associated with the latency-critical session that has not yet been received by the routing device from the source device, and wherein the at least one missing-packet value is less than the last-packet-received value;
identify a first packet identifier value of a next packet of the plurality of packets from the source device associated with the latency-critical session;
transmit the next packet to a client device based on determining that the first packet identifier value is greater than the last-packet-received value or that the first packet identifier value is the same as one of the at least one missing-packet value; and
modify the one or more data structures to indicate that the one of the at least one missing-packet value was received responsive to a determination that the first packet identifier value is the same as the one of the at least one missing-packet value.
9. The routing device of claim 8 , wherein upon determining that the first packet identifier value is greater than the last-packet-received value the processor is further configured to update the last-packet-received value in the one or more data structures to reflect the first packet identifier value.
10. The routing device of claim 8 , wherein the one or more data structures is selected from the group comprising: a file, an array, and a list.
11. The routing device of claim 8 , wherein to modify the one or more data structures the processor is further configured to delete the one of the at least one missing-packet value from the one or more data structures.
12. The routing device of claim 8 , wherein the one or more data structures comprises a bitmask.
13. The routing device of claim 12 , wherein to modify the one or more data structures the processor is further configured to change the bitmask to indicate that the one of the at least one missing-packet value was received.
14. The routing device of claim 8 , wherein the processor is further configured to:
receive at least one packet from the client device associated with the latency-critical session;
generate at least one copy-packet of the at least one packet from the client device associated with the latency-critical session; and
transmit the at least one packet and the at least one copy-packet to the source device.
