Abstract
-
This dissertafon focuses on improving performance of metropolitan area network (MAN) or local area network (LAN) prolocols at media access control (MAC) layers which are based on a dual/fold bus topological configuration. In older to enhance the performance, a simple, efficient, and versatile scheme is presented in the dissertation. The scheme is called grouping transmission, denoted by GT. It comprises two main ideas: (1) Dividing all the nodes in the network into multiple logical groups and assigning a group address to each group. (2) Setting up a post-source group transmission rule by which a busy slot carrying a segment (or a request) may carry new information (segments or requests) after the slot departs from its source group.;Several schemes have been proposed for improving throughput of dual bus MANs/LANs before. They are Destination Release (DR), Erasure Nodes (EN), Previous Slot Information (PSI), and SP-DQDB. The common advantage of the scheme, GT, over those schemes is: it can potentially support lower access delay and higher throughput in a simple and versatile (Slot Reuse, Pre-Use, or both) way.;Application of the GT scheme to two existing MAC protocols, DQDB and S++, produces six novel protocols. These protocols are group addressing distributed queue dual bus (DQDB-GA), group requesting distributed queue dual bus (DQDB-GR), non-post-request slot-pre-use distributed queue dual bus (DQDB-NSP), grouping distributed queue dual bus (DQDB-G), high throughput distributed queue dual bus (DQDB-H), and grouping addressing S++ (S++-GA).;Eight theorems on the throughput gains of dual bus MANs/LANs using the proposed scheme are founded and theoretical analysis results based on these theorems are exhibited in curves.;Simulation performance analysis studies (1) show that the new-designed protocols have higher performance or more flexible than existing ones and (2) verify that theoretical results are correct. Hence, the scheme can be efficiently utilized to support high speed data transmission.
