1.4 System Addressing
Addressing in the ArcLight system is accomplished using standard, four
octet IP addressing, as shown in Figure 1-10.
Each ArcLight satellite network utilizes a single class B IP network
address space for inter-network addressing. From the user’s
perspective, each VMBR within the satellite network is assigned, and
uniquely identified in the satellite network by an individual IP address
within the network’s class B address space.
IP Address: satellite interface (eg. 10.61.0.1)
The satellite network IP address space is used within the satellite
network domain only, and is not “visible” to customer networks or the
Internet.
Each VMBR and the Hub terminal performs an IP network address
translation function to accommodate the IP addressing scheme used in
attached customer networks and the Internet.
