Abstract

Methods and systems for transmitting data packets of a data session through a selected connection at a network node. The network node determines number of possible connections. When data packets belong to a new data session, a connection is selected to be the selected connection based on connection selection criteria. Further data packets belonging to the data session will be transmitted through the selected connection. A connection selection criteria include selecting a connection with the lowest latency among all connections. Evaluation packets based on the first data packet of the new data session are used to evaluate latency.

Claims (20)

  1. Claims
    1 . A method for transmitting data packets of a data session through a connection at a network node, comprising the steps of: a. determining a number of possible connections; b. receiving data packets from a local area network (LAN); c. when the data packets belong to a new data session: i. creating one or more first-evaluation packets; ii. sending the one or more first-evaluation packets to a first destination through one or more of the possible connections; iii. evaluating latency to the first destination of the one or more of the possible connections; iv. selecting one of the possible connections to be a selected connection; v. transmitting the data packets through the selected connection; d. when receiving further data packets belonging to the new data session: i. transmitting the data packets through the selected connection.
  2. 2. The method of claim 1 , wherein the steps (c) and (d) are performed if the data packets satisfy a match condition.
  3. 3. The method of claim 2, further comprising the step of: e. when the data packets do not satisfy the match condition, transmitting the data packets through any connection.
  4. 4. The method of claim 1 , wherein the steps (c) and (d) is performed if a first data packet of the data packets satisfy a match condition.
  5. 5. The method of claim 4, wherein the match condition is based on differentiated services code point (DSCP) value.
  6. 6. The method claim 4, wherein the match condition is based on DSCP value and further comprising the step of: resetting the DSCP value before performing step (c)(v) or d(i).
  7. 7. The methods of claim 4, wherein the match condition is based on address and port number of the first destination.
  8. 8. The methods of claim 4, wherein the match condition is based on deep packet inspection result.
  9. 9. The methods of claim 1 , wherein the step (c)(iv) is at least based on one of latency with the destination, bandwidth with the destination, location and tariffs.
  10. 10. The method of claim 1 , wherein the possible connections include at least one aggregated end-to-end connection.
  11. 1 1 . A network node comprising at least one network interface; at least one processing unit; at least one main memory; at least one non-transitory computer readable medium storing program instructions executable by the at least one processing unit for the steps of: a. determining a number of possible connections; b. receiving data packets from a local area network (LAN); c. when the data packets belong to a new data session: i. creating one or more first-evaluation packets; ii. sending the one or more first-evaluation packets to a first destination through one or more of the possible connections; iii. evaluating latency to the first destination of the one or more of the possible connections; iv. selecting one of the possible connections to be a selected connection; v. transmitting the data packets through the selected connection; d. when receiving further data packets belonging to the new data session: vi. transmitting the data packets through the selected connection.
  12. 12. The network node of claim 1 1 , wherein the steps (c) and (d) are performed if the data packets satisfy a match condition.
  13. 13. The network node of claim 1 1 , wherein the at least one non-transitory computer readable medium further storing program instructions executable by the at least one processing unit for the steps of: e. when the data packets do not satisfy the match condition, transmitting the data packets through any connection.
  14. 14. The network node of claim 1 1 , wherein the steps (c) and (d) are performed if a first data packet of the data packets satisfies a match condition.
  15. 15. The network node of claim 14, wherein the match condition is based on differentiated services code point (DSCP) value.
  16. 16. The network node of claim 14, wherein the at least one non-transitory computer readable medium further storing program instructions executable by the at least one processing unit for the steps of: resetting the DSCP value before performing step (c)(v) or d(i), wherein the match condition is based on DSCP value.
  17. 17. The network node of claim 14, wherein the match condition is based on address and port number of the first destination.
  18. 18. The network node of claim 14, wherein the match condition is based on deep packet inspection result.
  19. 19. The network node of claim 1 1 , wherein the step (c)(iv) is at least based on one of latency with the destination, bandwidth with the destination, location and tariffs.
  20. 20. The network node of claim 1 1 , wherein the possible connections include at least one aggregated end-to-end connection
