Abstract

This disclosure describes systems, methods, and devices related to managing egress traffic from a network to one or more peer networks. A method may include generating, using a load balancer of a network, a dynamic logical egress traffic threshold for a peer network; determining, using the load balancer, that first traffic from the network to the peer network is below the logical egress traffic threshold; directing second traffic from the network to the peer network based on the determination that the first traffic is below the logical egress traffic threshold; determining, using the load balancer, that the second traffic from the network to the peer network has reached the logical egress traffic threshold; and directing third traffic from the network away from the peer network based on the determination that the second traffic has reached the logical egress traffic threshold.

First claim

What is claimed:

1. A method of managing egress traffic to a peer network, the method comprising:
generating, by a device, using a load balancer of a network, a logical egress traffic threshold for a peer network;
determining, by the device, using the load balancer, that first traffic from the network to the peer network is below the logical egress traffic threshold;
directing, by the device, second traffic from the network to the peer network based on the determination that the first traffic is below the logical egress traffic threshold;
determining, by the device, using the load balancer, that the second traffic from the network to the peer network has reached the logical egress traffic threshold;
directing, by the device, third traffic from the network away from the peer network based on the determination that the second traffic has reached the logical egress traffic threshold; and
determining that fourth traffic from the network to a second peer network is below a second logical egress traffic threshold,
wherein directing the third traffic away from the peer network comprises directing the third traffic to the second peer network based on the determination that the fourth traffic is below the second logical egress traffic threshold.

2. The method of claim 1 , wherein the logical egress traffic threshold is a 95th percentile of traffic volume from the network to the peer network.

3. The method of claim 1 , wherein generating the logical egress traffic threshold is based on a traffic demand of customers of the network and a traffic capacity available at the network.

4. The method of claim 1 , wherein generating the logical egress traffic threshold is based on a cost of egress traffic to the peer network and a price sensitivity of a customer associated with the third traffic.

5. The method of claim 1 , wherein the logical egress traffic threshold is a first logical egress traffic threshold at a first time, the method further comprising:
generating, using the load balancer, the second logical egress traffic threshold for the peer network at a second time, the second logical egress traffic threshold different than the first logical egress traffic threshold;
determining, using the load balancer, that fourth traffic from the network to the peer network is below the second logical egress traffic threshold; and
directing fifth traffic from the network to the peer network based on the determination that the fourth traffic is below the second logical egress traffic threshold.

6. The method of claim 1 , further comprising:
generating, using the load balancer, the second logical egress traffic threshold for a second peer network, the second logical egress traffic threshold different than the logical egress traffic threshold;
determining, using the load balancer, that fourth traffic from the network to the second peer network has reached the second logical egress traffic threshold; and
directing fifth traffic from the network away from the second peer network based on the determination that the second traffic has reached the second logical egress traffic threshold.

7. The method of claim 1 , wherein the peer network is a paid peer internet service provider, wherein the second peer network is a settlement-free peer internet service provider, and wherein directing the third traffic to the second peer network is based on determining that the second peer network is a settlement-free peer internet service provider.

8. The method of claim 1 , wherein the network is a content delivery network.

9. A device for managing egress traffic to a peer network, the device comprising memory coupled to at least one processor, wherein the at least one processor is configured to:
generate, using a load balancer of a network, a logical egress traffic threshold for a peer network;
determine, using the load balancer, that first traffic from the network to the peer network is below the logical egress traffic threshold;
direct second traffic from the network to the peer network based on the determination that the first traffic is below the logical egress traffic threshold;
determine, using the load balancer, that the second traffic from the network to the peer network has reached the logical egress traffic threshold;
direct third traffic from the network away from the peer network based on the determination that the second traffic has reached the logical egress traffic threshold; and
determine that fourth traffic from the network to a second peer network is below a second logical egress traffic threshold,
wherein directing the third traffic away from the peer network comprises directing the third traffic to the second peer network based on the determination that the fourth traffic is below the second logical egress traffic threshold.

10. The device of claim 9 , wherein the logical egress traffic threshold is a 95th percentile of traffic volume from the network to the peer network.

11. The device of claim 9 , wherein to generate the logical egress traffic threshold is based on a traffic demand of customers of the network and a traffic capacity available at the network.

12. The device of claim 9 , wherein to generate the logical egress traffic threshold is based on a cost of egress traffic to the peer network and a price sensitivity of a customer associated with the third traffic.

13. The device of claim 9 , wherein the logical egress traffic threshold is a first logical egress traffic threshold at a first time, and wherein the at least one processor is further configured to:
generate, using the load balancer, the second logical egress traffic threshold for the peer network at a second time, the second logical egress traffic threshold different than the first logical egress traffic threshold;
determine, using the load balancer, that fourth traffic from the network to the peer network is below the second logical egress traffic threshold; and
direct fifth traffic from the network to the peer network based on the determination that the fourth traffic is below the second logical egress traffic threshold.

14. The device of claim 9 , wherein the at least one processor is further configured to:
generate, using the load balancer, the second logical egress traffic threshold for a second peer network, the second logical egress traffic threshold different than the logical egress traffic threshold;
determine, using the load balancer, that fourth traffic from the network to the second peer network has reached the second logical egress traffic threshold; and
direct fifth traffic from the network away from the second peer network based on the determination that the second traffic has reached the second logical egress traffic threshold.

15. The device of claim 9 , wherein the peer network is a paid peer internet service provider, wherein the second peer network is a settlement-free peer internet service provider, and wherein directing the third traffic to the second peer network is based on determining that the second peer network is a settlement-free peer internet service provider.

16. The device of claim 9 , wherein the network is a content delivery network.

17. A system for managing egress traffic to a peer network, the system comprising:
a load balancer of a network; and
at least one processor coupled to memory, the at least one processor configured to:
generate, using the load balancer, a logical egress traffic threshold for a peer network;
determine, using the load balancer, that first traffic from the network to the peer network is below the logical egress traffic threshold;
