Deployment in an ISP
Installation notes
• Configure the CacheRaQ 4 for Transparent Caching mode using one
network interface.
• Configure the access concentrators (“DIAL UP”) to use the CacheRaQ 4 as
their gateway.
• Enter the IP address of the router as the gateway for the CacheRaQ 4.
• One CacheRaQ 4 should be able to handle 1 Mb/s to 2 Mb/s of wide area
network (WAN) traffic. Contact Cobalt Networks, Inc. for more detailed
deployment guidelines.
Advantage
• You can keep quick-to-access copies of remote documents, saving
bandwidth and speeding up page access for users.
Disadvantage
• For large ISP points-of-presence (POP), one CacheRaQ 4 may not be
enough. In this case, a cluster of CacheRaQ 4s can be used.
