Survey of traffic control schemes and error control schemes for ATM networks
Among the techniques proposed for B-ISDN transfer mode, ATM concept is considered to be the most promising transfer technique because of its flexibility and efficiency. This paper surveys and reviews a number of topics related to ATM networks. Those topics cover congestion control, provision of multiple classes of traffic, and error control. Due to the nature of ATM networks, those issues are far more challenging than in conventional networks. Sorne of the more promising solutions to those issues are surveyed, and the corresponding results on performance are summarized. Future research problems in ATM protocol aspect are also presented
On the incentives to form strategic coalitions in ATM markets
This paper studies ATM coalitions in retail banking. We ask when it is profitable for banks to make agreements which ban direct ATM transaction fees. In the case of a coalition banks loose income from ATM transactions but relax competition in the banking market. We find that such agreements are profitable when the interchange fee is sufficiently high. When banks can collude on the interchange they always form a coalition. Coalitions may harm consumers but lead to higher total welfare. Moreover, we find that smaller banks have larger incentives to form ATM coalitions. Investment in ATM networks is typically higher with a coalition. --Banking competition,ATM networks,collusion

Survey of switching techniques in high-speed networks and their performance
One of the most promising approaches for high speed networks for integrated service applications is fast packet switching, or ATM (Asynchronous Transfer Mode). ATM can be characterized by very high speed transmission links and simple, hard wired protocols within a network. To match the transmission speed of the network links, and to minimize the overhead due to the processing of network protocols, the switching of cells is done in hardware switching fabrics in ATM networks.A number of designs has been proposed for implementing ATM switches. While many differences exist among the proposals, the vast majority of them is based on self-routing multi-stage interconnection networks. This is because of the desirable features of multi-stage interconnection networks such as self-routing capability and suitability for VLSI implementation.Existing ATM switch architectures can be classified into two major classes: blocking switches, where blockings of cells may occur within a switch when more than one cell contends for the same internal link, and non-blocking switches, where no internal blocking occurs. A large number of techniques has also been proposed to improve the performance of blocking and nonblocking switches. In this paper, we present an extensive survey of the existing proposals for ATM switch architectures, focusing on their performance issues
Performance and Buffering Requirements of Internet Protocols over ATM ABR and UBR Services
The Asynchronous Transfer Mode (ATM) networks are quickly being adopted as
backbones over various parts of the Internet. This paper analyzes the
performance of TCP/IP protocols over ATM network's Available Bit Rate (ABR) and
Unspecified Bit Rate (UBR) services. It is shown that ABR pushes congestion to
the edges of the ATM network while UBR leaves it inside the ATM portion.Comment: IEEE Communications Magazine, Vol 36, no 6, pp152-15
Principles for increased resilience in critical networked infrastructures
We propose a framework for deploying stronger, intelligent resilience mechanisms in mission-critical ATM networks over and above that offered by physical n-fold redundancy. We
compare the challenges facing power and data network resilience and discuss disruptive threats to real-world operations. Using recorded live data from an ATM data network we argue our proposed architecture with deployable, distributed on-demand anomaly detection and monitoring modules provides enhanced fail-secure versus current fail-safe resilience
Fees and Surcharging in automatic teller machine networks: Non-bank ATM providers versus large banks
This paper develops a spacial model of ATM networks to explore the implications for banks and non-banks of interchange fees, foreign fees and surcharges applied to transactions by customers at other than an own-bank ATM. Surcharging raises the price (foreign fee plus surcharge) paid by customers above the joint profit-maximizing level achieved by setting the interchange fee at marginal cost and not surcharging. Similar size banks would agree not to surcharge, but such an agreement is typically not possible between a bank and a non-bank. A high cost of teller transactions modifies the tendency towards high ATM fees.
