Abstract
A system and method for efficient fast failover of a primary link to a secondary link comprising monitoring an amount of user packets on said primary link and sending synthetic packets on said secondary link at a predetermined rate based on said amount of user packets wherein said predetermined rate is changed as a function of change in said amount of user packets.
Claims14
A method for managing synthetic packet transmission on a backup link, the method comprising:
- determining a first rate of data packets on a primary link;
- based at least in part on the first rate of data packets:
- determining a first synthetic packet rate, wherein the backup link is configured to be activated to carry data traffic in case of a degradation of the primary link;
- and
- keeping the backup link alive by sending, on the backup link, first synthetic packets at the determined first synthetic packet rate;
- and
- determining a second rate of data packets on the primary link, wherein the second rate of data packets is different from the first rate of data packets;
- based at least in part on the determined second rate of data packets on the primary link:
- determining a second synthetic packet rate different from the first synthetic packet rate;
- and
- sending, on the backup link, second synthetic packets at the determined second synthetic packet rate, wherein the second synthetic packet rate is determined as a function of the second rate of data packets on the primary link.

A network device system for managing synthetic packet transmission on a backup link, the network device system comprising a network device comprising:
- a memory configured to store instructions;
- and
- a control unit configured to access the instructions in the memory and to:
- determine a first rate of data packets on a primary link;
- based at least in part on the first rate of data packets:
- determine a first synthetic packet rate, wherein the backup link is configured to be activated to carry data traffic in case of a degradation of the primary link;
- and
- keep said backup link alive by sending, on the backup link, first synthetic packets at the determined first synthetic packet rate;
- determine a second rate of data packets on the primary link, wherein the second rate of data packets is different from the first rate of data packets;
- based at least in part on the determined second rate of data packets on the primary link:
- determine a second synthetic packet rate different from the first synthetic packet rate;
- and
- send, on the backup link, second synthetic packets at the determined second synthetic packet rate, wherein the second synthetic packet rate is determined as a function of the second rate of data packets on the primary link.
