Traffic control for point-to-multipoint ABR services in ATM networks has been studied extensively, but this is not the case for multipoint-to-point (mp-p) traffic control. No consensus has been reached concerning the issue of fairness of bandwidth allocation among multipoint connections, or between point-to-point and multipoint connections. Existing mp-p traffic control schemes for ABR services...

Rabbit metallothionein (MT) 2A complexes with Cd(II), Zn(II), Ag(I), Cu(I), Hg(II), arsenite, monomethylarsonous acid (MMA), and dimethylarsinous acid (DMA) have been examined using ion-mobility measurements and mass spectrometry in a triple-quadrupole mass spectrometer equipped with a segmented second quadrupole that doubled as an ion-mobility cell [Guo, Y.; Wang, J.; Javahery, G.; Thomson, B....

Flow control in heterogeneous networks requires careful planning, especially in the case of TCP over ATM, because TCP and ATM each protocol has a different flow control mechanism. The early packet discard scheme (EPD) is commonly used with ATM's unspecified bit rate service (UBR). This thesis presents an improvement to EPD called single packet discard scheme (SPD). The new scheme drops a packet...

The properties of cellulases from Helix pomatia have been studied by many workers, including Seilliere (1906), Karrer, Schubert & Wehrli (1925), Karrer & Schubert (1926, 1928) and de Stevens (1955). Cellulolytic enzymes have also been found in other invertebrates, such as Teredo (Greenfield, 1955) and Ctenolep8ima lineata (Lasker & Giese, 1956), and in a wide range ofmicro-organisms which inclu...

The multicast ABR service within ATM is required to efficiently support many data applications including IP multicasting. For point-to-multipoint connections, the branch points of a multicast tree replicate cells traveling from root to leaves and consolidate feedback traveling from leaves to root [1]. The branch-point consolidation is necessary to avoid excessive backward resource management (B...

This paper aims to present a comparative simulation study of the performance of TCP traffic over ATM networks with UBR and ABR services; to identify weaknesses of currently most promising ATM congestion control schemes; and to indicate the requirements for a fairer, simpler and more robust congestion control mechanism. Variety of congestion control schemes under various network configurations a...
