in our campus, we use catalyst 6006 as core switch.
there are four 1000BaseLX and two 1000BaseSX from catalyst6006 to our six main buildings.
and we have a vod server with 4 cahnnel Ultra 160 SCSI RAID(Adaptec SCSI RAID 5400S) which connect to catalyst 6006 with Gbits NIC.
the video streaming bit rate is 100kbps per request user.
consider TCP/IP protocol overhead, netwok collision,..etc.
our campus can support how many vode users??
