What is a Disaster? Networks that work in times of disaster should address: Events that affect a network (or require a new network) where either: –Capability is reduced –Demand/load increases (e.g., requires deployment of new network) These could be due to: Natural disasters Attacks –Physical attack –Cyber attack Non-malicious –Unintentional mis-configuration –Unexpected traffic surges Crises (Everyday disasters)
Problem Statement Given an existing network, and some event that results in a significant piece being destroyed –Whats an architecture that allows some reconstitution of communication? Three pieces –Rapid deployment of a network –Designing a network in the first place thats resilient to failures, disasters, etc. (discussion: can they also be efficient?) –Prioritized communication (is this even possible given the lack of trust among organizations?). Should this be explicit, or achieved through support for some set of services? Authoritarian vs. market-based mechanisms To what extent is the disaster network a separate entity? –Permanent vs. ephemeral networks How do we solve problems of scarcity? or is there glut? or both?
Lightning Talks Transient Network Architecture (TNA): Federation, Self Organization, Identification and addressing. Prototype with City of ABQ. PoMo and ResiliNets: Resilience and heterogeneity CABO / AIP: Identity, Sharing of physical resources Radio Wormholes: Traffic engineering in wireless mesh networks Interoperability: Spectrum gateway Instant infrastructure: Interoperability, rapid deployment Towards an Analytic Foundation for Network Architectures: architectures for multi-hop wireless, sharing Configuration assurance: Auto configuration
Target Requirements Federation –Interoperability: heterogeneity, ability to seamlessly interconnect networks of different types –Can function when there are conflicting claims of authority. Minimize conflicts by devising technologies that can function w/o login –What happens when multiple entities are in charge with/without overlaps of jurisdiction? –Support for heterogeneous communications protocols, media, etc. Ability to support sharing of physical infrastructure –Isolation: impact of failure should be contained Support for types of communication (voice, video, data, etc.) –Appropriate quality of service with graceful degradation –Prioritization of messages Security/authenticity of information, Identity
Target Requirements Rapid deployment –Efficient use of remaining available resources (vs. resilience?) –Fast resource discovery: whats there and how do I use it –Zero configuration/Self-organization –Self-forming and self-healing –Self-aware/situationally aware –Ability to support emergent infrastructure Continuity –Availability/reliability of communication and services (to what extent?) –Intermittent/no/unconventional connectivity (DTN) Management of glut –Too much information: attention management, announcement protocols, data analysis/reduction –Interference (at various layers : physical, namespace issues, etc.) Power –Interdependence: power grid requires networks and vice versa –Power awareness (can also help improve resilience)
Grand Challenges Communications interoperability training –Operation golden phoenix –From people skills to networks –Various disaster scenarios Bio attack Major fires –Anyone can participate. Geared for early responders Burning Man Tactical deployment –Network managers should not be preceding marines up the beach…
