Overview
ISO/IEC TR 20002:2012 - "Information technology - Telecommunications and information exchange between systems - Managed P2P: Framework" defines a framework and taxonomy for adding manageability to conventional peer-to-peer (P2P) systems. Rather than creating new P2P protocols or applications, this Technical Report (TR) classifies common P2P problems, specifies requirements for Managed P2P (MP2P), and describes an architectural framework and information flows to support manageability features. The goal is to help P2P service providers, ISPs and system designers bring operational controls to P2P networks while preserving P2P characteristics such as scalability and distributed resource sharing.
Key topics and technical requirements
ISO/IEC TR 20002:2012 covers the following technical areas and requirements:
- Problem classification - network-, service- and user-side issues caused by unmanaged P2P deployments (e.g., inefficiencies, policy and copyright concerns).
- Taxonomy and concept of Managed P2P (MP2P) - definitions of MP2P, peers, relay/super peers, and P2P service provider roles.
- Requirements to support MP2P, grouped by function:
- Traffic Management - mechanisms to observe and influence traffic behavior in P2P overlays.
- Cooperation Management - policies and incentives to coordinate peers and service providers.
- Contents Management - control over content fragments, distribution and integrity.
- Service Management - lifecycle and quality aspects for P2P-based services.
- Resource Management - allocation and usage of bandwidth, storage and compute resources.
- P2P User Management - identity, authentication and user-related controls.
- Distribution Management - strategies for efficient content dissemination.
- P2P Network Management - monitoring, control and fault handling for overlay networks.
- MP2P framework - definition of domains, entities, and high-level information flows that enable manageability.
- Informative use cases (Annex A) - example P2P applications and scenarios where MP2P concepts apply.
Practical applications and users
Who will use ISO/IEC TR 20002:2012:
- P2P service providers (P2PSP) and application vendors seeking guidance to add manageability features without redesigning protocols.
- Internet Service Providers (ISPs) who need methods to monitor, optimize or cooperate with P2P traffic while respecting overlay operation.
- Network architects and operations teams implementing traffic engineering, policy enforcement or distributed content delivery based on P2P overlays.
- Standards bodies and researchers investigating P2P manageability, content distribution and overlay governance.
Practical applications include improving P2P content delivery efficiency, aligning P2P services with network policies, and enabling cooperative arrangements between ISPs and P2P providers.
Related technologies and standards
- The TR references P2P concepts and technologies such as DHT (Distributed Hash Table), ALTO (Application-Layer Traffic Optimization) and signaling/overlay approaches (e.g., super peers).
- Note: ISO/IEC TR 20002:2012 does not define interoperability features with conventional P2P applications nor new P2P protocols - it provides a manageability framework to be applied to existing P2P deployments.
