2. Roland Bless Institut für Telematik Universität Karlsruhe (TH) www.tm.uka.de 2 IETF-69 / draft-bless-nsis-resv-aggr-01 Motivation End-to-end QoS requires usually inter-domain signaling Scalability considerations scalability in control plane (signaling) required so far only within a domain, RSVP-like aggregation using RAO codepoints (space too small) will not scale in the general inter-domain, because micro-flows visible again at domain egress need inter-domain aggregation concept Goal provide mechanisms to allow for dynamic creation of inter-domain reservation aggregates

3. Roland Bless Institut für Telematik Universität Karlsruhe (TH) www.tm.uka.de 3 IETF-69 / draft-bless-nsis-resv-aggr-01 Problems Determination of Aggregator and Deaggregator finding a deaggregator in other domains Signaling between Aggregator and Deaggregator direct signaling message association between Aggregator and Deaggregator A Priori Determination of a Flow‘s Path to allow for efficient integration of new flows into an existing aggregate avoid querying a path first Route Change Detection for aggregated flows in an aggregate

4. Roland Bless Institut für Telematik Universität Karlsruhe (TH) www.tm.uka.de 4 IETF-69 / draft-bless-nsis-resv-aggr-01 Route Change Detection Micro-Flows may leave the aggregate by re-routing events Should be detected: signaling should follow data path

5. Roland Bless Institut für Telematik Universität Karlsruhe (TH) www.tm.uka.de 5 IETF-69 / draft-bless-nsis-resv-aggr-01 Proposed Changes QoS NSLP New Route-Record object to find deaggregators Special A-RESERVE using SESSION_ID_LIST Null QUERY GIST New AF-MRM Type, Session-ID, PC-MRI Can be used for route check, setup of direct signaling associations and path prediction Checking for Session-ID of aggregate allows bypassing at GIST level
