Network Design

Our Network Design consists of a simple yet powerful and reliable topology. Based on switching technology for the Backbone, the connections to Servers and large clusters of computers, the network manages to provide the bandwidth necessary for today's applications.

There are six sites in total: Mamaroneck High School, Hommocks School, Central School, Chatsworth Avenue School, Murray Avenue School and the Mamaroneck Avenue School. Mamaroneck Avenue School and Murray Avenue School are connected via full T1 lines and the other three are connected through our own private fiber network which provide us with a Fast Ethernet connection. (You could see a schematic drawing of our network if you follow this link )

The sites are running on Optical Fiber for the backbone at 100Mbs. The backbone is connected via switches from Bay Networks.

In the Other Schools the equipment is slightly different mainly due to the fact that the design was done at a later date allowing us to implement the latest and most cost effective hardware solutions. The backbones are still Fiber, running at 100Mbs however the switches are the Bay Networks 28200's (bottom from Figure 1) which are less expensive than the 28104 used in the High School yet more flexible due to their modular design. Also the concentrators are the next generation 5000s' from Bay Networks (Figure3).

In the labs and wherever there are large clusters of computers we are using the Baystack hubs which are connected on switches with 10Mbs dedicated feeds.

The whole system is fully managed using the HP Openview management suite.
