Will this networking topology work?

[vziera]

Hi, I'm new into networking infrastructure so I would like to know if this topology will work,

Corrections will be greatly appreciated, and I would also like to know which devices have their own IP

Thank you!

Mark

Anything connected to the router should pull a private IP if DHCP is enabled. The layout is kind of scattered and my question is do you have the switch connected to the router for those wired devices?

It should work, but keep in mind if your running voip phones + wireless + competing with the Desktops for bandwidth out.....Could be a problem with Voip call quality

 

[Ahhzz]

I presume that the "Attached Access Point" is not a standard AP, but setup as a wireless bridge. On that note, most wireless units won't bridge unless you're attaching an identical unit on the other end.


edit: also, bpgt64 is correct: moving data from that many PCs and VOIP over a wireless bridge will bring some quality challenges....


edit 2 : here's a link for linksys and their directions on wireless bridging.

I believe by the lightning bolt between the two, he means the router to wirelessly bridge over to the AP, then using the AP to feed the switch, and subsequent devices.

I'd be curious to know what you have in mind as for a firewall. I made a few changes under the assumption that this is for a sort of small business/home office and the wireless router is a standard off-the-shelf type unit. I'd strongly recommend against relying on a wireless bridge like that for most almost all devices. Unless done really well, wireless is typically a bit shaky and shouldn't be relied on for much, especially VoIP phones.

Using a AP point as a repeater will half bandwidth to whatever is connected to it. I would say hardware everything you can to the switch.

Repeaters are de debil

As a WISP guy, very much this. Do it proper. Run a cable to a new AP, deploy on channels 1, 6, 11, repeat. Using RTS/CTS will allow networks sharing the same channel to coexist nicely with each other.

 

[bpgt64]

Anything running voip...I'd re-enforce, run a cable..even if it's a power line type deal.

What is this network for? Home? Business?

 

[remixedcat]

Some switches even have a VOIP VLAN

Mine does:

Sorry I just checked, thank you for your responses my friends
This network is for my CISCO homework, the homework is about drawing both physical and logical network topology of a real office but since I got no office nor know anyone who's got one, I decided to use my silly simpleton imagination instead...

Here's my revision in response to your inputs my friends:

BTW can a very good NAT router remove the need for that switch and that access point so we can save more money?

Now I need to define the parameters like IP, Mask, Gateway, etc on certain spots in the picture, I hope you guys can help me with this...

Oh and if you guys have a better topology idea for an office, please share it here. Thank you again my friends!

Sorry my friend but I think it's a bit too technically advanced for me to understand at the moment, those parameters @_@

cisco or cisco LINKSYS??

cisco or cisco LINKSYS??

I'm taking an unofficial CISCO CCNA course during my unemployment

 

[remixedcat]

but what do you have?

 

[vziera]

but what do you have?

You mean the peripherals? if so none, I have none

The pic is just my illustration of a small office network topology based on nothing but my limited knowledge, suppose they are mix of brands or just cisco

 

[remixedcat]

Cisco linksys and Cisco are completely different grades of products

"I have a Cisco router" Do you mean a Linksys router? "Yeah. A Link-see router." *sigh*

The main thing is that I really recommend against using a wireless bridge unless absolutely necessary. If you really need to, set up a point-to-point link, I've found that Ubiquiti gear is generally quite cost effective for this. RTS/CTS is just a method for access points and clients to avoid collisions with other normal wireless transmissions. It should even work between different wireless networks, but only if it uses the same channel as the other network (iirc). Looks like there's an access point right off the router? Unless that AP is physically far away from the router (with its built-in AP), it likely wouldn't be worth having the second AP there. Depends on the physical layout.

I don't think setting up a VLAN for VoIP isn't uncommon, but I'm not sure if it has any performance benefit, I think only security/simplicity. I'm not knowledgeable on this though. Remixed?

What kind of usage will the network see? I'm guessing just standard small business stuff, in which case unmanaged switches and off-the-shelf routers would likely do okay. Also, the device labeled "public switch", does that connect to anything else? It doesn't appear to be necessary.

 

[remixedcat]

VOIP VLAnS add QOS settings and have it isolated and protected and have higher priortity

also if you have more than one VLAN you NEED managed switch, as they have trunk ports and you need a trunk port to pass multi vlans thru one interface

 

[Ahhzz]

Personally, I'm more inclined to recommend the Netgear line. Stay away from the Linksys: their quality has dropped dramatically lately, in our experience.

Your circuit looks SUBSTANTIALLY better. As for eliminating the wireless AP and the second switch, Yes and No. You'll want to have a dedicated router to manage DHCP, with possibly as many as 4 ports on it: eliminating the switch wouldn't be a good idea. However, removing the Access Point, and simply going with a wireless router is definitely acceptable, as long as your range for the wireless is acceptable for the client computers. Problem is, most times, your router is located where the Internet comes in, and the laptops/other wireless devices are located much farther away than is reasonable to reach with that router. So, keep the switch, and determine whether or not your wireless devices will be close enough to get good signal from your router.

I do wonder why you have a "Public Switch" in place in there. Is that something that is required, or were you just unsure what goes there? Usually, you'll have an Internet connection come directly to your router, then out to an internal switch, unless you're sharing the internet feed with someone else.....

CISCO / CCNA (which he mentioned) is not a router brand he's using guys. It's a whole commercial certification test. This network does not really exist, and is assumed to be brand agnostic.

 

[brandonwh64]

If the switch is unmanaged then its mearly a means for more ports to connect to the router. If it is managed it can be configured for all types of features such as VLAN tagging and QoS.

Do you have the deliverables for the assignment?

I have a dumb switch that passes VLAN traffic between a few VM hosts. I don't think it's really designed to, just that it doesn't really care at all if packets are slightly over MTU. I know it's certainly hit-or-miss when it comes to which switch allows it though. Managed is always better, of course.
