A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Next Steps in Signaling Working Group of the IETF. Title : NSIS Operation Over IP Tunnels Author(s) : C. Shen, et al. Filename : draft-ietf-nsis-tunnel-08.txt Pages : 27 Date : 2010-02-09 NSIS QoS signaling enables applications to perform QoS reservation along a data flow path. When the data flow path contains IP tunnel segments, NSIS QoS signaling has no effect within those tunnel segments and the resulting QoS-untended tunnel segments could become the weakest QoS link which may invalidate the QoS efforts in the rest of the end-to-end path. The problem with NSIS signaling within the tunnel is caused by the tunnel encapsulation which masks packets' original IP header fields. Those original IP header fields are needed to intercept NSIS signaling messages and classify QoS data packets. This document defines a solution to this problem by mapping end-to-end QoS session requests to corresponding QoS sessions in the tunnel, thus extending the end-to-end QoS signaling into the IP tunnel segments.
