Abstract
Techniques for transferring address rights (e.g., internet protocol address(es), media access control address(es), etc.) amongst devices in a data center network fabric. A data center (DC) authority (e.g., network controller and/or a service controller) of a data center network fabric may determine that a device in the network is to communicate on an address in the network. The DC authority may create and sign a token that indicates a verifiable authorization to communicate on the address. The token may allow any device that posses the token to communicate on the address, following verification from an associated network switch. Additionally, the token may be signed by a device in the network in possession of the token, and delegated to another device in the data center network fabric following a migration of a service from one server to another, for example.
