Miranda MAC500IP Network Requirements

1. Data must go through switches or routers, no hub in the data path.
   
2. All links between switches or routers must be set to full duplex.
   
3. The Ethernet interface facing the MAC500 must be forced to full duplex and 100BaseT. (To match manual setting in the MAC500.)
   
4. The cable quality should be CAT 5 or higher.
   
5. The video traffic should pass by the shortest path from the end location to the router.
   
6. A VLAN should be created to separate regular data traffic from video traffic. Otherwise, have a separate Video Network from the Data Network. This eliminates unwanted broadcast and makes the network much more robust.
   
7. Disable SPT on the Ethernet interface facing the MAC500.
   
8. If Cisco routers are used, the main CPU must not exceed 70%.
   
9. The routers/switches/links must support a constant bit rate around 10 Mbps.
   
10. Set MTU to 1500.
    
11. The overall Jitter on the network should not be more than 1.5 milliseconds.
    
12. Use of LAN emulation should be restricted.
    
13. On some networks, QoS mechanisms with Policy management must be used.
    
14. Mirandas must be able to "ping" each other, and send and receive SNMP commands.
    
15. Mirandas are set to mark packets at a diffserve value of 88 to correspond to an IP Precedence value of 4. "Honor" and "re-mark" these packets appropriately.
