“…For example, an interconnection scheme that guarantees to traverse a small number of ISPs is probably the best alternative to the current method in terms of delay and settlement complexity. Indeed, it seems to be the most effective and practical solution to curtail the length of an e2e connection(i.e., the number of ISPs along which a packet should traverses; [11], [12], etc.). There have been many studies showing that most traffic passes through a small number of ISPs thanks to the technological advancement like Content Delivery Network (CDN).…”

“…Quality assurance, however, can be achieved based upon two trains of technological supports: (1) quality control and provisioning and (2) monitoring QoS (in each section of an e2e path) and auditing associated business transactions. Monitoring and auditing providers' behavior should precede, is argued by [11,12,17], and [19], so that the intermediaries for interconnections can conduct their business effectively since, without accurate monitoring and auditing, the main body of traffic exchange would have little information for allocating its resources efficiently, thereby, deteriorating the overall performance.…”

The International Telecommunication Union (ITU-T) is developing an architecture for Next Generation Network (NGN) to provide end-to-end Quality of Service (e2e QoS), for which Internet service provider (ISP) interconnections play a key role. Furthermore, for an effective e2e QoS-guaranteed interconnection across multiple ISPs, it is of a great help to develop a framework which enables ISPs to trade their unused network capacity. This study presents Hub-and-Spoke (H&S) interconnection model, where the hub called Neutral Internet Business eXchange (NIBX) arranges Bandwidth Trading (BT) on the basis of the market mechanism. After introducing qualitative and quantitative justifications of the H&S NIBX interconnection model, we propose a platform prototype for BT based upon the H&S NIBX architecture. Presented also are some detailed descriptions of key functional elements together with decision models embedded in the functions. Operations scenarios show potential benefits of the NIBX + BT architecture for ensuring e2e QoS, the ultimate goal of ITU-T's NGN.

“…in the first one [1] [2], the multi domains management is approached from a provider's point of view, which offers its clients with end-to-end services having pre-defined performances; the goal is to establish a compromise between (1) the global capacity of the domain and its external links, and (2) the number of potential clients; the second point of view relies on the statement that the concept of multi domains management is not mature yet [3] [4]; it is then a request signaling software's task to dynamically check and select the end-to-end service matching the QoS requirements; the goal is to invoke the service that best suits the QoS requirements. Hereafter, we will refer to this approach as the user's point of view.…”

This paper deals with the design of a distributed architecture and of mechanisms that are able to guarantee Quality of Service (QoS) in a set of DiffServ domains. The design includes the proposal of a signaling protocol to accept or reject the transmission of flows in a set of adequately controlled domains. More particularly, it provides a proposal for (1) selecting the end-to-end QoS paths resulting from concatenations of the IP services provided by the domains involved in the data path and (2) ensuring that the chosen concatenations fulfil the requested user QoS requirements. With respect to other work, this paper first tries to minimise the use of network resources by discovering the real performance of each domain. Second, the signaling protocol is designed to bring as less constraints as possible on the architecture. It defines the end-to-end concatenations only as a set of transfer bridges, or inter-domain links, and leaves all internal domain paths fully open to any implementation by the domain providers.The architecture, based on the use of bandwidth brokers, provides an answer to the two main problems related to such approaches, i.e. how to identify and build the sequence of the needed bandwidth brokers and how to select the ingress and egress routers of each of these domains to construct the end-to-end paths.Acknowledgement: This work has been is partially realised within the framework of the European IST EuQoS project (http://www.euqos.org).

“…Key components of an inter-domain QoS architecture have been described in [2]; At the service management level, [3] proposed SLA policies to enable INPs to agree how to distribute QoS across multiple domains. At the control level, QoS extensions to the underlying BGP have also been proposed [4] [5].…”

Provisioning for interdomain quality of service: the MESCAL approach

et al. 2005

View full text Add to dashboard Cite

This article presents an architecture for supporting inter-domain QoS across the multi-provider global Internet. Whilst most research to date has focused on supporting QoS within a single administrative domain, mature solutions are not yet available for the provision of QoS across multiple domains administered by different organizations. The architecture described in this article encompasses the full set of functions required in the management (service and resource), control and data planes for the provision of end-to-end QoS-based IP connectivity services. We use the concept of QoS Classes and show how these can be cascaded using service level specifications (SLSs) agreed between BGP peer domains to construct a defined end-to-end QoS. We illustrate the architecture by describing a typical operational scenario.
