1. An SNMP Usage for RELOAD draft-peng-p2psip-snmp-00 IETF #79 Yonglin PENG Yu MENG Wei WANG {peng.yonglin,meng.yu,wang.wei108}@zte.com.cn

2. Challenges for RELOAD Network Management Huge number of nodes and resources Difficult to manage the network through controlling a few network elements Nodes constantly join and leave the network Resources may dynamically relocated to distributed nodes Nodes may be behind NATs Multi-hop routing

3. Current Solutions SNMP – Management architecture for traditional networks – Persistent connection between manager and network elements – Not considering management for “resources” draft-ietf-p2psip-diagnostics-04 – “ping-like” and “traceroute-like” operations – Built in RELOAD protocol

4. Management scenarios useful to RELOAD Trap node failure or congestion Collect network and resource usage statistics On-demand configuration of nodes and resources Administrate overlay nodes Administrate and backup resources

5. Management Scenarios Capabilities provided by SNMP – Fault Management – Configuration Management – Accounting Management – Performance Management – Security Management SNMP Messages – Get Request – Set Request – GetNextRequest – GetBulkRequest – Response – Trap – InformRequest

6. Design Considerations Management Objectives – RELOAD Nodes – Resources – Servers(traditional methods are sufficient) Architecture

7. Node connecting to the network manager (for trap or O-Node collection) Network Managers register in RELOAD – SnmpRegistration – Mapping manager name to NodeID Nodes find network manager using RELOAD

8. Network manager connecting to nodes Use RELOAD to find node Manager maintains connection to O- Node SNMP after AppAttach

9. Network manager connecting to resources Using Resource ID to locate resources Use Appattach to connect to the Node responsible for the resource If connection already exists, no need to setup a new connection

10. Open Issues Should different managers be in charge of different nodes? Should different managers be in charge of different resources? If so, it is very difficult. SNMP carried by RELOAD messages? Coordinate distributed network managers? Definition of management information?

11. Next Steps Address part of the open issues Detailed design for SNMP usage Shall this become a WG item?

12. Thanks!
