• ### Interconnecting LANs and MANs to ATM

Publication Year: 1991, Page(s):259 - 270
Cited by:  Papers (6)
| | PDF (972 KB)

One of the challenges in the interconnection of LANs and MANs to ATM is the support of connectionless traffic in the ATM network. Several solutions have been proposed. A popular strategy seems to be that of maintaining a thin' (i.e. low bandwidth) VP (virtual path) between each pair of gateways, and of requesting more bandwidth whenever a burst comes in from the LAN or MAN. Unfortunately, this st... View full abstract»

• ### On performance characteristics of LAN interfaces with PING/PONG buffers

Publication Year: 1991, Page(s):562 - 568

Local area network performance can deteriorate when high temperatures cause cable attenuation to increase. This problem can be prevented by careful selection of insulating materials. Dissipation factor and dielectric constant for FEP, PVC, and ECTFE were measured at frequencies from 1 kHz to 300 MHz at 20°C and 60°C. Increases in values for these properties can be related to increases in c... View full abstract»

• ### A multiple-priority scheme for distributed queue dual bus networks

Publication Year: 1991, Page(s):204 - 213

Studies have shown that earlier versions of the distributed queue dual bus (DQDB) exhibited asymmetric segment access delay under heavy loads. A bandwidth balancing (BWB) mechanism was subsequently adopted to improve the access delay characteristics of DQDB. This mechanism, however, does not effectively support multiple levels of priority that DQDB may need in order to provide new services to the ... View full abstract»
