What does VC stand for?

TPORT modules on the FLASHWAVE 4500 platform support Generic Framing Procedure (GFP), Virtual Concatenation (VCAT), and Link Capacity Adjustment Scheme (LCAS) to allow a service provider to efficiently provision and manage Ethernet Virtual Private Line (EVPL) circuits over SONET.

Design considerations and use of virtual concatenation is emphasized, as well as the Link Capacity Adjustment Scheme and the Generic Framing Procedure.

Generic framing procedure (GFP) and virtual concatenation (VCAT) provide organizations with a number of choices in how they connect storage networks.

VIRTUAL CONCATENATION Virtual concatenation offers a way to overcome the problem.

Key Topics Covered Include: -- Traditional Ethernet -- Ethernet Standards And Growth Of Market -- SONET/SDh -- SONET As Ethernet Carrier - Overview -- Virtual Concatenation (VCAT) Technologies and Associated Techniques -- Packet Over SONET -- Classification of the EoS Transport Methods -- Alternative Technologies -- Methods Comparison: Ethernet Transport -- Topological Examples -- Transport Methods Technical-Economical Comparison: Examples -- Vendors' Community Position -- Service Providers Position Companies Mentioned Include: -- Agere Systems -- Agilent Technologies -- Ample Communications -- Advance Micro Devices -- Applied Micro Circuits Corp.

These include virtual concatenation (VCAT), the operation to provide more granularity, and the link capacity adjustment scheme (LCAS), an extension of VCAT that provides more flexibility.

Optical metro DWDM series portfolios of products are equipped with resilient packet ring technology, generic framing protocol service mapping, and virtual concatenation that enables efficient bandwidth utilization with native rate client data and storage interfaces.

Both modules support an extensive list of next-generation SONET/SDH features, including generic framing procedure (GFP), high and low-order virtual concatenation (VCAT), as well as high and low-order link-capacity adjustment scheme (LCAS).
