Embodiment Construction

[0021] Embodiments of the invention are described with reference to several examples of how the invention can best be made and used. Throughout the description and the several views of the drawings, like reference numerals have been used to designate like or corresponding parts, wherein the various parts are not necessarily drawn to scale. Referring now to the accompanying drawings, and more specifically to figure 1, describes a network architecture embodiment 100 in which the principles of the present invention can be more advantageously implemented. As shown, embodiment 100 represents a heterogeneous network environment, including various domains, such as customer network domains, provider network domains, and carrier network domains. Typically, these domains can be separated into a domain space conforming to the IEEE 802.lag standard and a domain space not conforming to the IEEE 802.lag standard. For the purpose of disclosing the present invention, it is assumed that the...

Abstract

A network environment including a provider network coupled to a first customer network site via a first access link and to a second customer network site via a second access link. The provider network is operable with the IEEE 802.1ag standard for propagating a remote link fault condition via an Ethernet Alarm Indication and Suppression (AIS) frame or a Continuity Check (CC) frame, which is translated into a locally compliant non-IEEE 802.1ag error delivery condition so that a management entity associated with the first customer network site is appropriately alerted.
