● Addressing: Subnet for each branch, and at least one for the data center.
Addresses should be organized in a hierarchy for summarization. Private IP
addresses in the private ranges (10.x.x.x, 172.16.x.x through 172.31.x.x, 192.168.x.x)
are recommended.
The following information summarizes the minimum hardware requirements for the Wide Area
Network.
● Router: Each location requires a manageable router with an Ethernet interface to the
LAN, a serial interface to DSU/CSU (or integrated CSU/DSU); plus the appropriate
interface(s) to a backup link, if implemented.
Note: The appropriate Routing Protocol depends on topology of the network and
the available bandwidth of the network. In general, RIPv2 or OSPF is best.
Internet access requires a separate link. Best practice specifies a separate router,
plus a firewall and Intrusion Detection System for security.
● CSU/DSU as specified by the common carrier. May be integrated into router, or may
require interface to PBX.
● Data Circuits: The Speed of data circuits depends on traffic volume. Traffic other
that Bankway transactions, such as e-mail, internet access, voice or video must be
considered. The following guidelines address Bankway traffic only. It is important for
you to evaluate your peak transaction volumes and to discuss this issue with your
preferred carrier14 to establish line speeds.
● Dedicated links: 256K minimum.
● Frame Relay: 256K minimum CIR to each branch. In general, the CIR to the data
center should approximate the sum of the CIRs to each branch. Modeling, monitoring
and tuning will provide more precise figures.
● Backup: ISDN BRI will supply adequate performance. Dial-up 56kb may provide
minimum performance if properly tuned. Redundant links forming a partially meshed
topology provides the best backup, if it can be cost justified. Other forms of redundant
links, such as Internet VPN may be explored.
● Internet access bandwidth and nature of this link depends on the Internet Service
Provider.
