It is often difficult and time-consuming to manage computer ‘moves, adds, and changes’ that take place in a switched, subnetted environment. It is even more difficult when the accepted network policy requires that a computer be configured and always connected to the network on a specific Virtual LAN (VLAN) based on its usage. An on-going problem is to keep all of the network host information up...

The incidence rates of cancers in men differ by countries of the world. We compared the incidence rates of three of the most common cancers (prostate, lung, and colon) in men residing in 164 different countries with the population-weighted light at night (LAN) exposure and with several developmental and environmental indicators, including per capita income, percent urban population, and electri...

It has been a long-term goal to discover peptides that can kill tumor cells while sparing normal tissues. Lan-7 is a novel, chemically stable peptide structurally related to somatostatin that contains a lanthionine bridge between the two cysteines in the peptide; TT-232 is a less stable analogue containing a disulfide bridge. The antitumor activity of Lan-7 was examined, relative to that of TT-...

Recently large scale distributed workstation LAN systems have been widely used in educational systems like educational centers in universities. In those systems, avoiding the large traffic caused by many users’ continuous operations is one of the most important problems. In this paper we modeled the users’ behavior in educational systems, and simulated and analyzed the traffic of the Ethernet L...

In this paper we examine quality-adjusted prices for local area network (LAN) equipment. Hedonic regressions are used to estimate price changes for the two largest classes of LAN equipment, routers and switches. A matched model was used for LAN cards and the prices for hubs were inferred by using an economic relationship to switches. Overall, we find that prices for the four groups of LAN equip...

This memo describes a framework for supporting IETF Integrated Services on shared and switched LAN infrastructure. It includes background material on the capabilities of IEEE 802 like networks with regard to parameters that affect Integrated Services such as access latency, delay variation and queuing support in LAN switches. It discusses aspects of IETF’s Integrated Services model that cannot ...

Bridges only forward The DECbridge 500 product traffic destined for other connects Ethernet/802.3 LANs; local traffic is local area networks (LANs) confined to its home LAN. to fiber distributed One important function of data interface (FDDI) bridges is the ability, LANs and is, therefore, under network management a fundamental element of control, to block traffic an extended LAN. Developers of...

Over the past few years, mobile networks have emerged as a promising approach for future mobile IP applications. With limited frequency resources, designing an effective MAC (Medium Access Control) protocol is a hot challenge. IEEE 802.11b/g/a/n networks are currently the most popular wireless LAN products on the market [1]. The conventional IEEE 802.11b and 802.11g/a specification provide up t...
