Abstract— Internet users are increases day by day then they want to access data more fastly and safely, so that higher capability internet services are very important. Today’s internet has the most of limitations which is important to remove. In future internet we used IPv6 protocol instead of IPv4 which have the larger address. It is important because the no. of users and system quantity are larger. In this paper we prepare the scope of future internet which will provide higher data transfer rates and high speed accessing to user. By designing new architecture and using new protocol version we can fastly access live TV and Multimedia data streaming on our computer. We can also enjoy the live video conferences because internet speed will be faster and powerful. Here we also describe the term dynamic caching which is important for accessing same data streaming on multiple places on the same time.

1   INTRODUCTION                                                                    
TODAY, Internet is the most important information ex-change ecosystem. It has become the core communication environment not only for business relations, but also for social and human interaction. The immense success of Internet has created even higher expectations for new applications and services, which the current Internet may not be able to support. Advances in video capturing and encoding have lead to massive creation of new multimedia content and applications, providing richer immersive experiences: 3D videos, interactive environments, network gaming, virtual worlds, etc. Thus, scientists and researchers from companies and research institutes world-wide are working towards realizing the Future Internet.
The Future Internet (FI) is expected to be a holistic information exchange ecosystem, which will interface, interconnect, integrate and expand today’s Internet, public and private intranets and networks of any type and scale, in order to provide efficiently, transparently, timely and securely any type of service (from best effort information retrieval to highly-demanding, performance critical services) to humans and systems. This complex networking environment may be considered from various interrelated perspectives: the networks & infrastructure perspective, the services perspective and the media & information perspective.

The Future Media Internet is the FI viewpoint that covers the delivery, in-the-network adaptation/enrichment and consumption of media over the Future Internet ecosystem.

Here we define that how the content discovery, re-trieval and delivery take place in the current Internet. Users want text, audio, videos from YouTube or weather informa-tion, but they do not know or care on which machine the desired data or service reside. Information/content retrieval and delivery may be realized by today’s Internet network architecture as shown in Figure 1. The network consists of: a) Content Servers or Content Caches (either professional or user generated content and services), b) centralized or clustered Search Engines, c) core and edge Routers and optionally Residential Gateways (represented as R1 to R5) and d) Users connected via fixed, wireless or mobile terminals.

Figure 1:  Today’s Internet Architecture

The first step is Content Discovery by the Search Engines: the Search Engines crawl the Internet to find, classify and index content and/or services. The second step is Content Discovery by the User: the user queries a Search Engine and gets as feedback a list of URLs where the content is stored. The last step is Content Delivery/Streaming: the user selects a URL and the content is delivered or streamed to him.

In order to show with an example the limitations of to-day’s Internet, let us consider the simple case of the delivery of a popular video from Content Server (e.g. a YouTube server). If a few dozen of users from a large building block request a video, the same video chunks will be streamed a few dozen of times. If a neighborhood has a few dozen of blocks, and a city a few hundreds neighborhoods, the very same video chucks will traverse the same network links thousands of times. If we continue aggregating at country and world-wide level, we will soon run out of existing bandwidth just for a single popular video stream.

This means that the three steps of content discovery and delivery can be significantly improved:
• (In the network) dynamic caching: If the content could be stored/cached closer to the end users, not only at the end-points as local proxies but also transparently in the network (routers, servers, nodes, data centre), then content delivery would have been more efficient.
•Content Identification: If the routers could identi-fy/analyses what content is flowing through them, and in some cases are able to replicate it efficiently, the search en-gines would gain much better knowledge of the content popularity and provide information -even when dealing with “live” video streams.
•Network topology & traffic: If the network topology and the network traffic per link were known, the best end-to-end path (less congestion, lower delay, more bandwidth) would be selected for data delivery.
•Content Centric Delivery: If the content caching location, the network topology and traffic were known, more efficient content-aware delivery could be achieved based on the content name, rather than where the content is initially located.
•Dynamic Content Adaptation & Enrichment: If the con-tent could be interactively adapted and even enriched in the network, the user experience would be improved.
3 High-level Future Internet Network Architecture

We envision an FI architecture which will consist of different virtual hierarchies of nodes (overlays), with different functionalities. In Figure 3, 3 layers are depicted; however this model would be easily scaled to multiple levels of hierarchy (even mesh instantiations, where nodes may belong to more than one layer) and multiple variations, based on the content and the service delivery requirements and constraints.
In a realistic roll-out scenario, the FI deployment is expected to be incremental. This is because we expect that today’s existing legacy network nodes (core routers, switch-es, access points) will not only remain and will even be the majority for a number of years; thus the proposed architec-ture should be backwards compatible with current Internet deployment. As shown in Figure 2, the Service/Network Provider Infrastructure Overlay is located at the lower layer. Users are considered as Content Producers (user generated content) and Consumers (we can then call them “Prosumers”).
Figure 2: FI high level architecture

This Network Infrastructure Overlay is the service, ISP and network provider network infrastructure, which consists of nodes with limited functionality and intelligence (due to the cost of the network constraints) . Content will be routed, assuming basic quality requirements and if possible and needed cached in this layer. The medium layer is the Distributed Content/Services Aware Overlay. Content-Aware Network Nodes (e.g. edge routers, home gateways, terminal devices) will be located at this overlay. These nodes will have the intelligence to filter content and Web services that flow through them (e.g. via deep packet Inspection or signalling processing), identify streaming sessions and traffic (via signalling analysis) and provide qualification of the content. This information will be reported to the higher layer of hierarchy (Information Overlay). Virtual overlays (not shown in the figure) may be considered or dynamically constructed at this layer. We may consider overlays for specific purposes e.g. content caching, content classification (and depending on the future capabilities, indexing), network monitoring, content adaptation, optimal delivery/streaming. With respect to content delivery, nodes at this layer may operate as hybrid client-server and/or peer-to-peer (P2P) networks, according to the delivery requirements. As the nodes will have infor-mation about the content and the content type/context that they deliver, hybrid topologies may be constructed, custo-mized for streaming complex media such as Scalable Video Coding (SVC), Multi-view Video Coding (MVC). At the highest layer, the Content/Services Information Overlay can be found. It will consist of intelligent nodes or servers that have a distributed knowledge of both the content/web-service location/caching and the (mobile) network instantiation/ conditions. Based on the actual network deployment and instantiation, the service scenario, the service requirements and the service quality agreements, these nodes may vary from unreliable peers in a P2P topology to secure corporate routers or even Data Centers in a distributed carrier-grade cloud network. The content may be stored/cached at the Information Overlay or at lower hierarchy layers. Though the Information overlay we can be always aware of the content/services location/caching and the network information. Based on this information, a decision on the way that content will be optimally retrieved and delivered to the subscribers or inquiring users or services can be made.
