Abstract
Various embodiments relate to a communications system and related method for determining an address of a service access point (SAP) upon establishment of a service over a packet data network. A customer SAP connected to a provider SAP may request a link-local address for another customer SAP on the far-end of the packet data network. When the service, such as a virtual leased line (VLL) is not yet established, the provider SAP may generate an address for the customer based on another value, such as its own media access control (MAC) address. The generated address may then allow the service to become established, which may allow Neighbor Solicitation and Neighbor Advertisement packets to be sent, analyzed, and extracted. The provider SAP may then replace the generated address with the address extracted from the Neighbor Solicitation or Advertisement packet received after the service was established.
