Method for migration of session accounting to a different stateful accounting peer

A network device configured to execute a plurality of virtual machines, the virtual machines configured to support network function virtualization (NFV), the plurality of virtual machines to support a method for migrating a subscriber session from a first authentication, authorization and accounting (AAA) accounting peer to a second AAA accounting peer, where the first AAA accounting peer is stateful, the network device comprising:

• a non-transitory computer readable medium having stored therein a AAA client;
• and
• a processor coupled to the non-transitory computer readable medium configured to execute a virtual machine from the plurality of virtual machine, the virtual machine to execute the AAA client, the AAA client configured to receive an accounting start packet from an AAA client application, to forward the accounting start packet to the first AAA accounting peer, to receive an accounting update or accounting stop packet from the AAA client application, to select the second AAA accounting peer from the available accounting peers, in response to determination of a connection failure with the first AAA accounting peer, to determine whether the received packet is the accounting update packet or the accounting stop packet, to re-mark or re-label the accounting update packet, from the AAA client application, as an accounting start packet;
• and to send the re-marked or re-labeled accounting start packet from the AAA client application to the second AAA accounting peer.

A computing device configured to execute a method for migrating a subscriber session from a first authentication, authorization and accounting (AAA) accounting peer to a second AAA accounting peer, where the first AAA accounting peer is stateful, the computing device comprising:

• a non-transitory computer readable medium having stored therein a AAA client;
• and
• a processor coupled to the non-transitory computer readable medium configured to execute the AAA client, the AAA client configured to receive an accounting start packet from an AAA client application, to forward the accounting start packet to the first AAA accounting peer, to receive an accounting update or accounting stop packet from the AAA client application, to select the second AAA accounting peer from the available accounting peers, in response to determination of a connection failure with the first AAA accounting peer, to determine whether the received packet is the accounting update packet or the accounting stop packet, to re-mark or re-label the accounting update packet, from the AAA client application, as an accounting start packet;
• and to send the re-marked or re-labeled accounting start packet from the AAA client application to the second AAA accounting peer.

A control plane device in a network including a plurality of data plane devices, the control plane device in communication with the plurality of data plane devices and configured to implement a method for migrating a subscriber session from a first authentication, authorization and accounting (AAA) accounting peer to a second AAA accounting peer, where the first AAA accounting peer is stateful, the control plane device comprising:

• a non-transitory computer readable medium having stored therein a AAA client;
• and
• a processor coupled to the non-transitory computer readable medium configured to execute the AAA client, the AAA client configured to receive an accounting start packet from an AAA client application, to forward the accounting start packet to the first AAA accounting peer, to receive an accounting update or accounting stop packet from the AAA client application, to select the second AAA accounting peer from the available accounting peers, in response to determination of a connection failure with the first AAA accounting peer, to determine whether the received packet is the accounting update packet or the accounting stop packet, to re-mark or re-label the accounting update packet, from the AAA client application, as an accounting start packet;
• and to send the re-marked or re-labeled accounting start packet from the AAA client application to the second AAA accounting peer.
