The Asynchronous Transfer Mode (ATM) has been standardized and widely accepted as a technique to support future B-ISDN networks. Two of important functions for traffic control in ATM networks are policing and routing. All previous studies have treated policing and routing in a separate way. A combination of policing and routing can guarantee a better quality of service and network utilization. So far, many network control strategies have been proposed, but they are not well suited for high speed networks.

The routing algorithms can be classified into source, distributed and hierarchical routing. Source routing algorithms are conceptually simple, but they suffer from scalability problem. Distributed routing algorithms are more scalable, but loops may occur, which make the routing to fail. Hierarchical routing has been used to cope with the scalability problems of source routing in large internetworks. The hierarchical routing retains many advantages of source routing.

In Asynchronous Transfer Mode (ATM) networks, the traffic control design becomes an important challenge, because of the diverse services support and the need for an efficient network resource engineering. Two of important functions for traffic control is ATM networks are policing and routing. The goal of these two functions is to guarantee the required quality of service and increase the network utilization. All previous studies have treated policing and routing in a separate way.

The Asynchronous Transfer Mode (ATM) tech- nique has been accepted as a basis for the future B-JSDN net- works. In ATM networks, all information is packetized and transferred in small packets of fixed length, called cells. The packetized information transfer, without flow control between the user and the network and the use of statistical multiplexing, results in a need of a policing mechanism to control the traffic parameters of each virtual connection in order to guarantee the required quality of service (QoS). Policing of the peak cell rate is generally not complex and can be achieved by using a cell spacer or other policing mechanisms (PMs).

In recent years, various kinds of aggregates are being developed for the purpose of utilization of solid waste. Generally, these types aggregates contain microscopic pores in these matrixes. Porous aggregates which were chosen as the subject study, are artificial light-weight aggregate(expanded shale type and sintered fly-ash Type), artificial super light-weight aggregate (expanded shale type and sintered fly-ash type, ryolite type and waste glass type) and recycled Aggregate, total pore volume, pore radius distribution, density, absorption, strength of aggregate were measured.
