RFC 2491 - IPv6 over Non-Broadcast Multiple Access (NBMA) networks. G. Armitage, P. Schulter, M. Jork, G. Harter.(Site not responding. Last check: 2007-10-15)
RFC 2491 IPv6 over NBMA networks January 1999 This use of PVC links does not mandate, nor does it prohibit the use of extensions to the Neighbor Discovery protocol which may be developed for either general use of for use in PVC connections (for example, Inverse Neighbor Discovery).
RFC 2491 IPv6 over NBMA networks January 1999 For the purpose of conformance with this document, a router MAY choose to initiate the discovery of a better first-hop when it determines that an identifiable flow of IP packets are passing through it.
RFC 2491 IPv6 over NBMA networks January 1999 Description The shortcut limit option is used by a host in a Neighbor Solicitation message sent as a shortcut trigger to a default router.

Standards Track [Page 42] RFC 2491 IPv6 over NBMA networks January 1999 Description The shortcut limit option is used by a host in a Neighbor Solicitation message sent as a shortcut trigger to a default router.
At the other extreme, NBMA networks that support dynamic establishment and teardown of Virtual Circuits (or functional equivalents) may be used to emulate the service provided to the IPv6 layer by conventional broadcast media such as Ethernet.
The remainder of this document is structured as follows: Section 2 explains the generalization of IPv6 Link to "Logical Link" when used over NBMA networks, and introduces the notion of the Transient Neighbor.
Shortcut connections are justified on the grounds that demanding flows of IP packets may exist between source/destination pairs that are separated by IP routing boundaries.

Merritt, M.L., 1997, Computation of the Time-Varying Flow Rate from an Artesian Well in Central Dade County, Florida, by Analytical and Numerical Simulation Methods: Water-Supply Paper 2491, 44 p.
Simulation of the development of a plume of brackish water in a surficial aquifer caused by discharge from a flowing artesian well required an accurate estimate of the rate of flow during a 40-year period.
