4 Introduction Changes to the internet infrastructure of the internet 1) Cooperation of many ISP 2) Partnership with the CP The paper focuses on the enhanced 1) benefits for ISP 2) Their increased role in supporting a content-centric future Internet architecture 4

5 Introduction The reluctance of ISPs to be involved in a next-generation Internet model has been considered as one of major hindrances in the evolution of the Internet Solution = Overlay architecture the evolution of the Internet overlay architecture, which can be deployed incrementally and supports a business model that provides a win win situation for both network service provider (i.e. the ISPs) and CP. 5

6 Introduction Surrogate a network edge device, located close to the user, which acts as a relay for the user to access, organize, provision and monitor Internet content. integrate into content delivery networks as well as other overlays and serve as a basis for implementing a content centric Internet architecture. 6

7 Background Structure of Internet Core network : acts as a backbone and its routers support multiple telecommunications interfaces to switch and forward packets at the highest speed. Edge networks : are connected to one or multiple core routers and are in close proximity to the end users, assuring aggregation and distribution of their traffic. Access networks : interconnected to the edge routers. 7

8 Background Content Delivery CDNs are the Web and designed to reduce the overhead of the content server by bringing the content to the network edge, closer to the user, similar to a cache memory on a computer. Content is pushed to the edge and is delivered as fast as possible through appropriate replication and caching technologies. 8

9 Background Content Centric Networks CCN (Content Centric Networks) any network that considers content as a central and paramount entity recently the notion of named content that decouples a content s location from its identity, security and access, has been introduced. retrieves a content by parsing its name The emergence of a CCN, evolution of the CDN into a rational infrastructure which can support a variety of content from multiple origins in a flexible and scalable way raises a number of for its key players. 9

10 Background ISP involvement The role of ISPs is limited to that of a data carrier, through fast packet delivery(at the core) and access provisioning (at the edge). 10

11 Background Limits of CDN model limit to consider is the potential for growth in the infrastructure of CDN operators, as the content model changes. Increasing the size of the deployed infrastructure in the ISP domain is too costly, redundant to a large degree, and not scalable. Value for ISPs it would be better to have servers close to the users, it would also be better to have application servers close to suppliers of content. User-side issues As the Internet becomes more content oriented, other issues such as restriction to access, security and performance guarantees arise 11

12 Future Internet Architecture The surrogate implements support for a number of content specific services including content search, request, create or add. Surrogates and content repositories create an overlay of a logical content centric Internet architecture. End users are logically directly connected to this overlay through virtual clients. Inside this virtual cloud, surrogates operate as forwarding nodes while repositories act as storages. In the infrastructure domain, surrogates and repositories are located in the edge networks and hence are connected through the Internet core. 12

13 A Surrogate Architecture Web server, which receives the users input through a GUI running on the Web client inside the UE. Web based GUIs are used to implement the virtual client side since most user platforms (UE) come equipped with a Web browser Application servers with the help of the index engine and local cache gather content and transform this content into the service the user requests. The surrogate through the application servers allow the content/service providers to deploy their services. Index engine accomplishes server selection and traffic engineering through access of the ISP s topology and overall overlay network condition, although the precise means to accomplish. 13

14 A three layer content delivery system No specific CDN provider owns nor implements the CDN resources ISP is responsible for the surrogates and the repositories implemented in its AS 3 layer (CP) The CP not only transfers content to the repositories but also deploys value added services through the application servers of the surrogates layer (InP) InP(i.e. the ISP) is responsible for implementing and maintaining the physical resources (e.g. routers, switches, surrogates, repositories, physical links, etc.) inside the AS (Autonomous System) it operates. 2 layer (Virtual Network Provider) The VNP gathers resources from one or more ISPs and builds a virtual network, which is composed of virtual nodes and links The VNP always offers interfaces to the CP in such a way that the surrogates and the content repositories are deployed at the edge of the Internet

15 Benefit to Providers Server selection and traffic engineering For example in case of Akamai, the optimal server selection is substantially degraded for end users outside of the USA. coupled and affect one another s performance Local content access CP needs not have to deal with a CDN provider with a global presence to replicate its content around the world. Instead of that the regional ISPs could provide superior local network coverage and deliver flawless high quality media content throughout its AS. Enhanced security and billing End user is always authenticated by the ISP to grant access to the network. This authentication can be further extended through a Single Sign-On (SSO) technique to access restricted content. The ISPs could also control the delivery of copyrighted content to an illegitimate user. The ISPs are also capable of implementing fine grained billing for the usage of commercial content and could supply the billing information to the CPs. 15

16 Comparison with CDN Comparison of proposed model with CDN Criteria CDN (Akamai) Proposed model At th edge Redirection, caches and local storages. Implements computing (application server) and storages at the edge. Virtual client No notion of client virtualization. Virtualize user s client through computing support at the Edge Cloud. Deliver Content only Service and content InP s role InPs are not involved. CDN provider maintains the CDN. Active involvement of the InPs who maintains the Edge Cloud infrastructures Business model Potential providers CDN and CPs are in the value chain. Need major investment, suitable for industry giants. InP, VNP (in case of content overlay) and CP/SP are in the value chain. Need small investment, good for even medium/small companies. Potential vendors Pricey service, long-term contract, not suitable for small companies. Cheap service, suitable for small to medium companies. 16

17 Conclusion Through the implementation of surrogates at the edge of the Internet, our architecture creates opportunities for the ISPs to be actively involved in the value chain of content delivery. The surrogate based architecture has some features distinct from the traditional CDNs, including control interfaces for both ISPs and the CPs, use of ISP supplied information in server selection and traffic engineering, virtualization of end user s client, enhanced security, etc. These features have potential to motivate the ISPs in redesigning the content delivery architecture for the Internet. 17
