“…Techniques like Digital Fountain [44] or data compression can be used to perform this bulk transfer. An alternative to wired networks is a satellite network like the one used in CODIS [41], allowing the utilization of multicast/broadcast to improve performance.…”

“…There are different techniques and mechanisms to control the number of replicas and placement of them in the surrogates, but of all them are based in the existence of a database in the content manager of the network. Different approaches exist: a user-centric alternative more related with P2P systems [15]; existence of a central content manager with knowledge of every object stored in the surrogates of the network, but without specifying its structure [18,40], e.g., Akamai [12], and CODIS [41] which introduces the concept of Constellation Server as content manager of a CDN based on a satellite distribution network. Globule [15] and CoDeeN [16] as open developments of CDN systems include a content management system.…”

“…Akamai [4], which acquired Speedera, Nine Systems, Digital Island and others, provides a distributed computing platform that delivers web, media streaming, software and applications. Another popular CDN is CODIS [5], which aim is to deliver documents and media streams over a satellite-based CDN using a central highbandwidth satellite as a single-hop backbone for a continental CDN. We can also find mobile CDNs such as MarconiNet [6], an IP-based radio and TV network built on standard Internet protocols.…”

It is known that a group-based system provides better performance and more scalability to the whole system while decreasing the communication traffic. Group-based architectures in Content Delivery Networks (CDNs) could be a good solution to the need of scalability. There is not any group-based CDN in existence, although we proposed in reference [1] a group-based system to interconnect CDNs of different providers. This article shows a Content Delivery Network based on grouping surrogates. We will show the benefits of our proposal and its application environment. We will describe the protocol developed to connect surrogates from the same group and from different groups. The neighbor selection algorithm is based on their proximity in order to provide lower content distribution times and trying to assure Quality of Service (QoS) by connecting to surrogates with higher available capacity. Real measurements of the network control traffic and of the performance of the surrogates will be shown. Finally we will show the differences with the system proposed in reference [1].

“…It can also be used to join different Content Delivery Networks such as the ones developed by service providers Akamai [10], Speedera [11] or CODIS [12], the ones developed by different vendors, such as Cisco's ECDN solution or Nortel's Content Director/Cache [13] or to join open developments such as Globule [14], Coral [15], CoDeeN [16] or SCDN [17], many of them with different structure and operation protocols. So the protocol described in this paper could be deployed to run over that implemented protocols.…”

Content Delivery Servers can be grouped into logical networks according several criteria: similar characteristics; functionalities; type of data delivered or proximity. Sometimes, it could be useful to find a way to join these autonomous logical networks. Research in this area focuses in centralized solutions, e.g. using a single point for data delivery between these groups. This paper proposes a novel architecture to interconnect content delivery servers from different groups and explains how they establish logical connections. The topology of logical connections, between servers clustered in different groups, changes depending on their capacity or because of server failures. The proposal is based on a hierarchical structure, in which the role of the server in the architecture is given by several parameters, being also scalable and fault-tolerant. We present the analytical model for this interconnection architecture and results obtained for some defined parameters. Finally, developed an application which used the protocol described in this paper and we deployed the proposed architecture in a real environment to obtain accurate measurements.
