  1. Targets for the SG 13 Caracas Meeting Working Party 4/13 Network Performance and Resource Management • Topic Overview • WP 4/13 Structure and Responsibilities • Planned Meeting Schedule • Key Technical Issues • Expected Results

  2. Planned WP 4/13 Caracas Meeting Schedule

  3. Question 4/13Broadband and IP Related Resource Management • Issue -- AAL2 Resource Mgmt (D111, D112, D144) • “Burstiness” of AAL2 connections strongly impacts link utilisation for a given delay quantile. For a fixed delay quantile, utilisation decreases with increasing burst size. • “Shaping” can be used to control bursts, increase utilization • Connection admission control must be based on AAL2 link characteristics (ALC) that describe traffic burstiness • Expected Results -- New I.371 Text on AAL2 RM (Developed jointly with Q2/13) Q4/13 will also progress work on Draft Rec. Y.iptc (Traffic Control and Resource Management in IP-Based Networks)

  4. Question 6/13Performance of IP-Based Networks and the Emerging Global Information Infrastructure • Issue -- IP Packet Transfer QOS Parameters, Objectives • New parameter (e.g., SESIP) to specify packet loss clustering • Metric(s) and objectives for IP packet delay variation (jitter) • Delay specifications for long complex paths • IP network Hypothetical Reference Paths, allocation rules • Possible new Recommendation on QOS at the TCP layer • Expected Result -- Stable Y.1541, Revision for Y.1540 IP/MM Workshop recommended Joint Meeting (SGs 13, 16, 12, 11) to harmonize QOS Classes

  5. Question 7/13B-ISDN/ATM Cell Transfer and Availability Performance • Issue -- Rec. I.356 performance allocation models • ATM/ADSL access links, ATM/IP Interworking (D138) • Use of inter-operator (rather than country-based) network models (TD11) • Expected Results: Proposednew performance models and allocation methods

  6. Question 8/13Transmission Error and Availability Performance • Issue -- “G.optperf” allocation model (D101) • Proposal: Change "international paths" to "multi-operator paths crossing international borders" • Questions: • Should fixed G.828 “terminating country” block allowance (17.5%) be allocated to “terminating domain”? Should the “routing factor” for the terminating domain be copied from G.828? • How many intermediate domains should be assumed? (Proposal: 4) • How allocate to intermediate domains? (Proposal: use block allowance and routing factor, satellite allocation from G.828) • Likely Results: New HRP and allocation proposals

  7. Question 9/13Call Processing Performance • Issue -- Draft Y.1530 QOS Classes • Proposals • Specify multiple call processing QOS classes for Hybrid IP networks to meet varying service requirements (D126) • Implement International Emergency Preference Scheme (E.106) in Hybrid IP networks (D117) • Expected Result: New call processing QOS class structure, including a default “best effort” class IEPS requirement could be documented by defining an “emergency priority” QOS class
