In response to a request from the source to facilitate the direct connection, the examples identify the destination among multiple destinations based on available bandwidth from the multiple destinations. The examples transmit a security token to the identified destination for authentication of traffic from the source, wherein the source includes an indication of a period of time. Based on the indication of the period of time, the examples limit the direct connection. ## Claims ### Claim 1 A method, executable by a networking device, the method comprising: in response to a request from a source to facilitate a direct connection, identifying a destination among multiple destinations based on available bandwidth from the multiple destinations; transmitting a first key pair to the source and a second key pair to the identified destination, wherein the transmitted second key pair includes an indication of a period of time; and limiting the direct connection based on the indication of the period of time. ### Claim 2 (depends on 1) The method of claim 1 comprising: receiving an activation signal from the destination to track the period of time in response to an arrival of traffic at the destination. ### Claim 3 (depends on 1) The method of claim 1 wherein limiting the direct connection based on the indication of the period of time comprises: transmitting a stop signal to the source in response to an expiration of the period of time. ### Claim 4 (depends on 1) The method of claim 1 comprising: receiving health information and the available bandwidth from each of the multiple destinations. ### Claim 5 (depends on 1) The method of claim 1 comprising: transmitting a response to the source wherein the response includes the first key pair and an Internet Protocol (IP) address to the identified destination. ### Claim 6 (depends on 1) The method of claim 1 comprising: approving the request from the source prior to transmission of the first and the second key pairs. ### Claim 7 (depends on 1) The method of claim 1 wherein the first key pair and the second key pair are different types of key pairs. ### Claim 8 (depends on 1) The method of claim 1 wherein the request from the source includes an events per second (EPS) information corresponding to traffic at the source. ### Claim 9 A non-transitory machine-readable storage medium comprising instructions that when executed by a processing resource cause a networking device to: in response to a request from a source to facilitate a direct connection, identifying a destination among multiple destinations based on available bandwidth from the multiple destinations; transmit a security token to the identified destination for authenticating traffic from the source, wherein the security token includes an indication of a period of time; and limit the direct connection based on the indication of the period of time. ### Claim 10 (depends on 9) The non-transitory machine-readable storage medium of claim 9 wherein to limit the direct connection based on the indication of the period of time comprises instructions that when executed by the processing resource cause the networking device to: transmit a signal to stop a transmission of traffic from the source to the destination based upon an expiration of the period of time. ### Claim 11 (depends on 9) The non-transitory machine-readable storage medium of claim 9 comprising instructions that when executed by the processing resource cause the networking device to: track the period of time based upon traffic arrival at the identified destination. ### Claim 12 (depends on 9) The non-transitory machine-readable storage medium of claim 9 comprising instructions that when executed by the processing resource cause the networking device to: transmit a response to the source including an Internet Protocol (IP) address to the identified destination. ### Claim 13 A system comprising: a first load balancer adaptable to: in response to a request from a source to facilitate a direct connection, identify a destination among multiple destinations based on available bandwidth from the multiple destinations; transmit a first key pair to the source and a second key pair to the identified destination, wherein the transmitted second key pair includes an indication of a period of time; and limit the direct connection to the source and the identified destination based on the indication of the period of time. ### Claim 14 (depends on 13) The system of claim 13 comprising: a second load balancer adaptable to handle the facilitation of the direct connection when the first load balancer is unavailable. ### Claim 15 (depends on 13) The system of claim 13 comprising: the identified destination adaptable to transmit an activation based on an arrival of traffic from the source, wherein the activation signal indicates a tracking of an expiration of the period of time.
