Variable traffic Consistent predictable average bandwidth use but varies over a short period of time The ATM 150 Uniform distribution emulates a variable series of traffic bandwidths and chooses them in a uniform manner based on a minimum maximum series of bursts with a step choice between bursts The ATM 150 Gaussian distribution emulates a variable normal distribution that is there is a starting point rising normally through a bell curve to a peak and then falling along a mirror image of the rising curve to the beginning value The ATM 150 Poisson distribution is a subset of the Gaussian distribution with the difference being a more aggressive rise in the bell curve to a peak with a normal curve fall The ATM 150 Ramp distribution is a test not an emulation to show the policing functions of the ATM network This test increases the bandwidth requirements over time seconds This test is also useful in monitoring the Cell Transfer Capacity Verification listed earlier in this chapter The ATM 150 Customized distribution permits the user to create their own distribution of traffic and enter the emulation through the floppy drive of the ATM 150 The Randomize function scrambles the starting point of the statistical distributions as well as all values through the entire distribution to better emulate traffic in the network that does not always begin at a certain point The Randomize function is defaulted ON in

Advantages of ATM Small cell size Low latency to support reai time services like voice and f video Fixed cell length Fast hardware switching and scalabilit Standardization Usable in ali networks LAN or WAN e Scalability ATM is a scaleable technology The ATM standard describes a 53 byte cell format but is silent as to items like rates framing or physical bearers Thus many different systems such as local area networks switches and public networks can use the same format Previously standards usually tied rates and formats into one package incompatible with anything else With ATM a cell generated by a 100 Mbps LAN can be carried over a 45 Mbps DS3 to a central office and switched into a 2 4 Gbps SONET transport system This illustrates three very different systems LAN network transport switching with the message in the same format rate scaled to suit the application Features Benefit A 1 12 15 94 ATM Basics ATM 150 User Manual e Transparency ATM is application transparent The cell size is a compromise between the long frames generated by data communications applications and the short repetitive needs of voice It is also suitable for such services as video ATM will allow free mixture of data and voice or video within the same application with no worry concerning compatibility with LAN or wide area communications Granularity ATM allows the network to be tailored to the application rathe

TM Basics ATM 150 User Manual Why both VPI and VCI The Virtual Path concept originated with concerns over the cost of controlling B ISDN networks The idea was to group connections sharing common paths through the network into identifiable units the Paths Network management actions would then be applied to the smaller number of groups of connections paths instead of a larger number of individual connections VCI Management in this instance includes call setup routing failure management bandwidth allocation and others For example use of Virtual Paths in an ATM network reduces the load on the control mechanisms because of the functions needed to setup a path through a network are performed only once for all subsequent Virtual Channels using the path Changing the trunk mapping of a single Virtual Path can affect a route change for every Virtual Channel using that path e PT The next three bits PT or payload type indicate the type of information carried by the cell ATM cells will be used to carry different types of user information that may require different handling by the network or terminating equipment Cells will also be used to transfer operations and maintenance messages across the network between users or between user and service provider Codes within this three bit field will indicate the type of message in the payload e CLP The last bit of byte four CLP indicates the cell loss priority and is set by the user This
