Discussion Overview

The discussion centers around whether one computer using maximum bandwidth on a LAN affects the bandwidth available to other computers on the same network. Participants explore the implications of network design, including the use of switches versus hubs, and the prioritization of different types of data traffic.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants assert that if one computer is using maximum bandwidth, it will affect other computers on the network, while others suggest this is not necessarily the case depending on the network setup.
  • There is a discussion about whether bandwidth is usually artificially or naturally constrained, with one participant arguing it must be artificially constrained.
  • One participant notes that the impact on bandwidth depends on the type of network topology, mentioning that in a Ring Network, computers do not influence each other's maximum rate.
  • Another participant highlights that in a network using an Ethernet layer 2 switch, if the switch is non-blocking, other computers' bandwidth may not be diminished.
  • Participants mention the importance of prioritizing different types of data traffic, such as voice over data, and refer to concepts like COS/CoS and QoS for managing bandwidth allocation.
  • There are references to the obsolescence of certain network types, like Token Ring, and discussions on the security and efficiency of various protocols in peer-to-peer networks.

Areas of Agreement / Disagreement

Participants express differing views on whether one computer's maximum bandwidth usage affects others, indicating that the discussion remains unresolved with multiple competing perspectives on the topic.

Contextual Notes

Participants do not fully explore the assumptions behind their claims, such as the specific configurations of network devices or the definitions of bandwidth constraints. The discussion also does not resolve the implications of different network topologies on bandwidth usage.

If one computer on a LAN network is using maximum bandwidth on, say, downloading a file, then will this affect the bandwidth of other computers on the network? And is bandwidth usually artificially constrained or naturally constrained?

Yes.

It has to be artificially constrained.

Are you just talking about within the LAN, or do you mean the internet? When you say download, I am assuming you mean the internet. You have to set parameters allocating priority to the type of data (for example, if you have both voice and data, voice would be given priority as it is more sensitive than data), you can also give priority to the type of data, file transfer over browsing for example. It can either be set in the router or in the network. The two types are commonly referred to as COS/CoS (class of service) or QoS (quality of service).

Depends, A Ring Network is piece-wise, and none can influence the max_rate of another.

End-to-End is dominated by throughput.

Whereas, common in connectivity, parallel, then it would be affected. This is due to the adapter-hub interface. Where the hub has to check-balance all transfers.

Token Ring and the others are pretty obsolete.

Yes.
Well not necessarily. If the LAN is setup on an Ethernet layer 2 switch vs a hub, and the switch is non blocking, then no the bandwidth to the 'other computers' on the same LAN will not be diminished.

Yeah, the token use is. Not secure enough. But, where peer-to-peer observation/computation is necessary, other protocols are used. As in Research and Development.

Any physical peer-to-peer network, just about, will take into account what it can. Where power is a must.
