Internet Engineering Task Force (IETF) L. Berger Request for Comments: 6002 LabN Updates: 3471, 3473, 3945, 4202, 4203, 5307 D. Fedyk Category: Standards Track Alcatel-Lucent ISSN: 2070-1721 October 2010 Generalized MPLS (GMPLS) Data Channel Switching Capable (DCSC) and Channel Set Label Extensions Abstract This document describes two technology-independent extensions to Generalized Multi-Protocol Label Switching (GMPLS). The first extension defines the new switching type Data Channel Switching Capable. Data Channel Switching Capable interfaces are able to support switching of the whole digital channel presented on single channel interfaces. The second extension defines a new type of generalized label and updates related objects. The new label is called the Generalized Channel_Set Label and allows more than one data plane label to be controlled as part of a Label Switched Path (LSP).

Introduction This document describes two technology-independent extensions to Generalized Multi-Protocol Label Switching (GMPLS). Both of these extensions were initially defined in the context of Ethernet services, see [RFC6004] and [RFC6005], but are generic in nature and may be useful to any switching technology controlled via GMPLS. The first extension defines a new switching type, which is called Data Channel Switching Capable (DCSC). DCSC interfaces are able to support switching of the whole digital channel presented on single channel interfaces. The second extension defines a new type of Berger & Fedyk Standards Track [Page 2] RFC 6002 GMPLS DCSC Channel Extensions October 2010 generalized label and updates related objects. The new label is called the Generalized Channel_Set Label and allows more than one data plane label to be controlled as part of a GMPLS Label Switched Path (LSP). 1.1.
