Abstract
A disclosed apparatus may include and/or represent a first node and a second node communicatively coupled to the first node. In some examples, the second node is configured to send binding information to the first node and then resend the binding information to the first node due at least in part to not having received an acknowledgement of successful installation of the binding information from the first node. Various other devices, systems, and methods are also disclosed.
Claims15
A system comprising:
- a first node;
- and
- a second node communicatively coupled to the first node via a network that implements a dynamic host configuration protocol (DHCP), wherein the second node is configured to:
- send, to the first node, DHCP binding information that comprises a mapping of a unique identifier of the first node to an Internet Protocol (IP) address;
- receive a negative acknowledgement of unsuccessful installation of the DHCP binding information from the first node;
- identify, within the negative acknowledgement, data indicating that the first node failed to successfully install the DHCP binding information due at least in part on a transient error, the second node having been programmed to:
- resend the DHCP binding information if the data indicates that the install failed due to the transient error;
- and
- refuse to resend the DHCP binding information if the data indicates that the install failed due to a permanent error;
- resend the DHCP binding information to the first node due at least in part to the transient error;
- and
- receive an acknowledgement of successful installation of the DHCP binding information from the first node after resending the DHCP binding information.

A node comprising:
- a communication interface;
- and
- a processing device communicatively coupled to the communication interface, wherein the processing device is configured to:
- send, to an additional node via the communication interface, dynamic host configuration protocol (DHCP) binding information that comprises a mapping of a unique identifier of the additional node to an Internet Protocol (IP) address;
- receive a negative acknowledgement of unsuccessful installation of the DHCP binding information from the additional node;
- identify, within the negative acknowledgement, data indicating that the additional node failed to successfully install the DHCP binding information due at least in part on a transient error, the processing device having been programmed to:
- resend the DHCP binding information if the data indicates that the install failed due to the transient error;
- and
- refuse to resend the DHCP binding information if the data indicates that the install failed due to a permanent error;
- resend the DHCP binding information to the additional node due at least in part to the transient error;
- and
- receive an acknowledgement of successful installation of the DHCP binding information from the additional node after resending the DHCP binding information.

A method comprising:
- sending, by a node to an additional node via a network that implements a dynamic host configuration protocol (DHCP), DHCP binding information that comprises a mapping of a unique identifier of the additional node to an Internet Protocol (IP) address;
- receiving, by the node, a negative acknowledgement of unsuccessful installation of the DHCP binding information from the additional node;
- identifying, within the negative acknowledgement, data indicating that the additional node failed to successfully install the DHCP binding information due at least in part on a transient error, the node being programmed to:
- resend the DHCP binding information if the data indicates that the install failed due to the transient error;
- and
- refuse to resend the DHCP binding information if the data indicates that the install failed due to a permanent error;
- resending, by the node, the DHCP binding information to the additional node due at least in part to the transient error;
- and
- receiving, by the node, an acknowledgement of successful installation of the DHCP binding information from the additional node after resending the DHCP binding information.
