| You can make configuration adjustments to improve the UDP multicast performance of peer-to-peer communication in your <%=vars.product_name%> system. |
| |
| Before you begin, you should understand <%=vars.product_name%> [Basic Configuration and Programming](../../basic_config/book_intro.html). See also the general communication tuning and UDP tuning covered in [Socket Communication](socket_communication.html) and [UDP Communication](udp_communication.html#udp_comm). |

| - **[Provisioning Bandwidth for Multicast](multicast_communication_provisioning_bandwidth.html)** |
| |
| Multicast installations require more planning and configuration than TCP installations. With IP multicast, you gain scalability but lose the administrative convenience of TCP. |
| |
| - **[Testing Multicast Speed Limits](multicast_communication_testing_multicast_speed_limits.html)** |
| |
| TCP automatically adjusts its speed to the capability of the processes using it and enforces bandwidth sharing so that every process gets a turn. With multicast, you must determine and explicitly set those limits. |
| |
| - **[Configuring Multicast Speed Limits](multicast_communication_configuring_speed_limits.html)** |
| |
| After you determine the maximum transmission rate, configure and tune your production system. |
| |
| - **[Run-time Considerations for Multicast](multicast_communication_runtime_considerations.html)** |
| |
| When you use multicast for messaging and data distribution, you need to understand how the health monitoring setting works and how to control memory use. |
| |
| - **[Troubleshooting the Multicast Tuning Process](multicast_communication_troubleshooting.html)** |
| |
| Several problems may arise during the initial testing and tuning process for multicasting. |
