Briefing Topics • Mobility Defined • Mobility Related Challenges to Interoperability • Our Mobility Enhancements • Introduction to Mobile Networks Working Group • Conclusion
What Does Mobility Include? • Three types of mobility • Ad hoc • No predefined infrastructure, moving nodes and networks, no dependence on any particular node • “Connected” mobility • Node or network moving within the larger internetwork while remaining connected; predefined network infrastructure • “Disconnected” mobility • Node or network disconnected and then moving to a new location; when reconnected, could be within an ad hoc or infrastructured network Many Mobility Experiences – One Goal: Seamless IPMobility
What are Mobility Areas of Interest? • 10 Mobility Problem Areas: • Network Mgmt & Planning • Quality of Service • Routing • Ad hoc Networking • Network and Node Mobility • Information Assurance • Applications Interactions • Transport Layer Protocols • Multicast • Physical and Data Link constraints MNWG addressing the challenges at Layers 3 and 4, and interfaces to higher and lower layers
What are the Key Mobility Challenges? • Realizable, accepted E2E QoS for mobile (and fixed) environments • Information exchange between Application QoS, Networking QoS, Mgmt QoS • QoS across domain boundaries • Open standards for Mgmt of QoS • Network Planning & Mgmt for multi-domain, mobile environment • Operator mgmt of resources in dynamic network(unstable links, dynamic membership) • Topology construction and config files cannot always require a person in the loop • Management of murky domain boundaries as nodes and networks move • Integration of Network Mgmt with Mobility Mgmt (centralized arch issues) We are all familiar with these challenges!
Key Mobility Challenges –(cont.) • Reliable transport of data in a mobile, bandwidth constrained, “lossy” environment • Border Gateway Protocol (BGP) scalability • mobility customizations to terrestrial protocols violate tenets • terrestrial protocols have too much overhead for bandwidth limited links, rapid network topology changes creates too much overhead and causes convergence problems, lack of standards for highly responsive routing • More stable links, identity and routing coupled in IP address • Multiple separate efforts addressing mobility, with insufficient resources • Internetworking with mobile networks and mobile infrastructure We are all familiar with these challenges!
NCOIC is Addressing the Challenges • Mobile Networking Overview • Helps identify Mobility issues that need to be addressed in a program • Publicly available from NCOIC website • Mobile Networking Evaluation Process • Rigorous top down engineering process for evaluation of standards to support net centricity and identify / address gaps • Architecture Tenets • We’ve developed various architecture tenets that provide important guidance for NCO design for mobility, and integrated them with others (Swedish FMV) • Communications Services Identification & Recommended Standards • Support to SOA • Proposed comm standards for MECI first 72 hours scenario • Establishing coordinated effort with SDR-F, OMG, IEEE, SDR-UG NCOIC Has Products for Your Use

Architectural Tenets • IP Architecture Tenets: • Network Transparent to users • Universal reachability • “Always on” paradigm • IP based • E2E interoperability • Distributed Cooperation • Network of networks • Robust • Modular, loosely coupled • Scalable • Layered model • Transparently secure • Simple core network, complexity at edge • Gateways at edge • Application Transparent • Separate control, mgmt, data planes • Local awareness • Avoid implicit assumptions • Deviation weighed against cost • Sensible use of cross-layer design • IA Tenets: • Multi-level trust & performance assurance • Defense in Depth using Pervasive Authentication • Mutual authentication • Policy Driven • Devices & Users are security principles • Trusted mgmt • Network independent accreditation • Multiple security abstractions • Interdependent network & security boundaries • E2E trust maintenance • Support Filtering and Sharing • Mobility Tenets: • Mobility mgmt complementary with Net Planning & Mgmt • Decentralized, hierarchical, distributed Mobility mgmt • Available Mobility Mgmt information • Fixed & moving network infrastructure • Heterogeneous networks, connectivity, interactions, and speed of movement • Technology independent requirements • Self-forming • Location and Identity are independent • Usual services incl QoS, IA, and Mgmt • Reasonable mgmt overhead • Autonomous behavior • Network structure supports mobility NCOIC is Providing Guidance for Mobile Systems Development
