IP services platforms complement carriers’ existing access and backbone equipment and are capable of extending critical Layer 2 (L2) and Layer 3 (L3) functions such as broadband aggregation (such as broadband remote access server [BRAS), IP routing, and ATM switching as well as Ethernet switching and interworking functions to the carrier’s network edge. IP service platforms can aggregate a wide range of carrier access and connectivity services such as wireless access (for example WLAN, FBWA, mobile), cable modems, fiber, and traditional dial-up. A new network model is poised to dominate next-generation service provider infrastructures.”]
