Slide 16

Co-Location Scalable Servers Web Caches Services Within the Network: Content Distribution "Web Grid" Parallel Network Backbones Internet Exchange Points

Slide 17

Services in the Internet: Napster, Gnutella, Freenet, … Something more than unlawfully sharing RIP\'d music and recordings from CDs and DVDs … Cooperative development of indexes Peer-to-companion figuring versus customer server registering No incorporated record/execution problem area/focus for foreswearing of administration assault, and so on. Be that as it may, existing "glib" executions create a considerable measure of system activity Technologies will develop for proficient sharing of data inside groups E.g., Lotus Notes, newsgroups, and so forth. Connecting library lists together

Slide 18

Content Distribution Through Multicast Overlay Network Content Broadcast Network Edge Servers Load Balancing Thru Server Redirection; Content Broadcast Management Platform and Tools Redirection Fabric Inter-ISP Redirection Peering Services Within the Network: Streaming Media Broadcasters Clients Steve McCanne

Slide 19

Service-Level Peering Via Redirection Need basic engineering to permit distinctive sellers to make diverse parts and work with each other while as yet contending The difficulties Define the redirection design New customer/foundation convention & API (a la DNS) Do so in reverse perfect way Others… One of the following huge compositional issues for the Internet… McCanne, FFNets

Slide 28

The iMode Story 21 million Internet-fit phone supporters NTTDoCoMo has turned into the world\'s biggest ISP! Most regular utilized applications: Voice discussions Text messages Animated kid\'s shows Specialized ringing tones Japanese youngsters, particularly females, driving the focused improvement of new administrations!

Slide 29

Huge Expense of New Telecomms Infrastructures Auctions for 3G range: 150 billion ECU; Capital costs may coordinate range costs, all before first income Build it, yet will they come? Convincing administrations have the effect Alternative plan of action Collaborative organization of remote base Competitive provisioning of administrations Better approach to manufacture a system? … Partition frequencies in light of endorser thickness Eliminate copy reception apparatus destinations Leverage basic backhaul systems

Slide 30

Application Services in the Mobile Wireless Network Enabling more client focused/versatile applications User inclination administration administrations Application coordination administrations Context-mindfulness administrations Content-confinement administrations Mobility-model extraction administrations Content adjustment to get to network execution Content adjustment to get to customer capacities Storage relocation in light of client portability Special about portable remote? Abuse of area and versatility Resource compelled nature of remote environment

Slide 31

Infrastructure Services in the Mobile Wireless Network Forming dynamic confederations Discovering confederates, setting up trust Open administration/asset allotment model Service creation, foundation, position; Exchange assets, abilities, status; Allocate taking into account monetary strategies; Manage trust among members; Service handling/peering Dynamically develop overlays on segment administrations gave by fundamental administration suppliers Redirect to option administration cases
