“…Others argue that controlling the overload is required in order to preserve an acceptable throughput per active flow, thus ensuring the QoS offered to users. In fact, a minimum TCP bandwidth is required to achieve a minimal session level user utility [11]. The use of AC will assure this user utility and avoid wasting network resources on retransmissions and incomplete transfers.…”

Abstract-The trend toward the integration of current and emerging applications and services in the Internet has launched new challenges regarding service deployment and management. Within service management, admission control (AC) has been recognized as a convenient mechanism to keep services under controlled load and assure the required QoS levels, bringing consistency to the services offered.In this context, this article discusses the role of AC in multiservice IP networks and surveys current and representative AC approaches. We address and compare the architectural principles of these AC approaches and their main features, virtues and limitations that impact on the quality control of network services. We identify important design aspects that contribute to the successful deployment of flexible and scalable AC solutions in multiservice networks.

“…For example, the model predicts an average flow's throughput equal to 20% of the link's capacity when the occupancy is around 90%. In the case of [53], the AC algorithm measures the incoming traffic to the link's queue and derives the actual overflow (loss) probability using a statistical model. A new arriving connection is rejected whenever this packet loss probability exceeds a given threshold.…”

“…The start of the flow (connection) is implicitly indicated to the router through its first packet, i.e., the TCP connection establishment packets (SYN or SYN/ACK). The AC response is also implicitly indicated to the flow: in the case of acceptance, the connection establishment is allowed to proceed by forwarding the detected establishment packet; in the case of rejection, the connection establishment is aborted, by sending an RST packet to the sender [52] or by discarding the detected establishment packet [53]. Therefore, the AC is simple and moreover, it is fast as it is made as soon as a new flow arrives (in a hop-by-hop scheme, no signaling…”

Network schemes for TCP elastic traffic in the Internet

TCP elastic traffic is generated by the traditional "data" applications in the Internet, such as web browsing, peer-to-peer file sharing, ftp, e-mail and other. These applications are built on top of TCP, which provides reliable transfers and adjusts the sending rate to the network conditions to achieve the maximum possible throughput, a feature that makes TCP flows to be called "elastic". From the point of view of the network, TCP elastic traffic requires the maximum possible throughput above a minimum value, a network service that we call the Minimum Throughput Service (MTS). In this paper we survey the main network schemes that have been proposed in the Internet to provide this service for TCP elastic traffic, classified in two broad groups, the ones that do not use Admission Control (AC) and the ones that do use it. For each network scheme we describe the main characteristics of the service (whether the minimum throughput can be different or is the same for all flows, whether isolation among flows is provided, etc.) and their architecture (the specific traffic conditioning, queue disciplines and AC mechanisms used, the required state, the use of signaling, etc.).

“…These solutions lead to reduced control information and overhead, but eventually to QoS degradation. To control elastic traffic, for efficient network utilization, implicit strategies i.e., without requiring explicit signaling between applications and the network, have also been defined [11].…”

Abstract. The use of Internet as an ubiquitous communication platform puts a strong demand on service providers regarding the assurance of multiple service levels consistently. Designing flexible and simple service-oriented management strategies is crucial to support multiconstained applications conveniently and to obtain a deployable and sustainable service quality offer in multiservice IP networks. In this context, this paper proposes the use of a self-adaptive QoS and SLS management strategy sustained by a service-oriented traffic admission control scheme to ensure the negotiated quality levels. A proof-of-concept of the proposed strategy is provided, illustrating its ability to self-adapt and control efficiently distinct QoS requirements in multiservice IP networks.
