A Quality of Service Decision Model for ATM-LAN/MAN Interconnection
نویسندگان
چکیده
The two technologies adopt diametric opposite approaches to QoS issues. ATM acts in a declarative manner – “this is the QoS I would like/require”. LAN protocols describe the QoS in an operational manner – “this is the portion of the system bandwidth I want every 125μs”. These two approaches mean that there is a definite need for a gateway between the two QoS models. Such a gateway is also likely to have to perform operations on the data flow between the two transmission technologies.

متن کاملImplementation of Virtual LANs over ATM WANs
Virtual LANs (VLANs) allow to interconnect users over campus or wide area networks and gives the users the impression as they would be connected to the same local area network (LAN). The implementation of VLANs is based on ATM Forum’s LAN Emulation and LAN/ATM switches providing interconnection of emulated LANs over ATM and the LAN ports to which the user’s end systems are attached to. The pape...
متن کاملTCP Performance Over ATM Based LAN Interconnection Services
We consider the performance of TCP/IP traffic over a LAN interconnection service (such as SMDS) based on ATM. In order to achieve a reasonable utilisation of the ATM network and at the same time guarantee the packet loss probability specified by SMDS, a shaping buffer is necessary in the MAN to WAN interworking unit. Through simulation studies we show that good TCP performance may be achieved w...
متن کاملLoss and Delay Study of LAN Interconnection over ATM
LAN interconnection is expected to be the rst service ooered by ATM based B-ISDN. Since traac on the current LANs is connectionless and bursty, the main challenge will be to provide an eecient con-nectionless service over connection oriented ATM network. One of the methods proposed for transporting bursty LAN traac over ATM is to set up an ATM connection upon arrival of a burst and close the co...
متن کاملAn Experiment in Parallel Computing over a Heterogeneous ATM-Based MAN
The advent of high-speed local and wide area networks has made geographically distributed NOWs an appealing platform for supercomputing applications. In particular, ATM is an emerging standard that seems to meet the communication requirements of such applications. This paper presents the results of performance tests of a real-world parallel program over a heterogeneous ATM-based public metropol...
