Network Design in a Shared Office
Posted on 2011-05-02
I am currently helping implement a network design for a small office that is being refurbished with the end aim being that it will be let out to small local businesses, partly on a per-room basis.
It has four floors with the top two floors each holding three small rooms capable of holding between 1 and 6 desks each.
The bottom two floors are open plan and will both be let out to one business who have their own network equipment they're supplying themselves. Their 1st floor contains the server room which will serve all four floors.
For the top two floors which will be rented out per room, I have designed a cabling infrastructure using CAT5e and providing every room with enough CAT5 sockets for every desk plus two spare, one for a router and one for a server/network printer/other.
Each socket has a seperate cable linked back to the switch in the cable cabinet in the server room. The switch for these two floors will be a VLAN-capable gigbit switch such as the Netgear ProSafe GS748TS. The idea is that each room will be isolated on a VLAN by the switch. Should a business want more than one room, the VLANs can be modified to create one VLAN spanning two or more rooms as needed.
If the larger business occupying the bottom two floors decides to expand and take over part or all of the top two floors, I envisaged that we could simply create one VLAN for all rooms on the switch and connect their switch to it via a patch lead, thus linking the whole building.
For broadband, each room will have its own ADSL-enabled phone line run to each room with an ethernet socket adjacent. This allows the room's tenant to supply their own router and sort out their own broadband without affecting the rest of the building or incurring additional support costs for the landlord.
My basic question is this - as I have limited experience of this, I hoped someone would be able to give me an idea of whether this is the best way to do it or whether there is a better way? The seperate broadband is a must as the landlord does not want to get involved in shared lines etc.
Any feedback is much appreciated.
