Whenever possible, use a dedicated private network for communication
between the host management software (ACSLS, HSC, or other software) and
the library.
If a shared network is required, these actions can help with the communication
between the host and the library.
1. Directly connect the library to a switch.
2. Place the library on its own subnet.
3. Use a managed switch that can:
• Set priorities on ports to give the host and library higher priority.
• Provide dedicated bandwidth between the host and the library.
• Create a VLAN between the host and the library.
4. Use a virtual private network (VPN) to insulate host to library traffic.
Network Recommendations
A private network connection to an Ethernet hub or switch is recommended for
maximum throughput and minimum resource contention.
When implementing the Dual TCP/IP feature, it is strongly recommended that
you and the system administrator work closely together to define the
configuration.
The simplest topology (private network connections to a hub or switch) is often
the best solution. Simplification will:
• Offer maximum throughput
• Provide minimum resource contention
• Lend itself to higher security for library communication
• Supply the least expensive alternative
• Provide quick identification of any problems within the network
These are only suggestions; however, the customer’s network and their
desired topology are ultimately the determining factors. For certain topologies,
a more complicated setup is required. Many will require consultation between
the system administrator and another level of services.
