| <H2>GemFire Distribution</H2> |
| |
| Distributed GemFire moves information between physical machines in a |
| number of different ways. The JCache implementation uses {@link |
| org.apache.geode.distributed.internal.DistributionMessage}s |
| to send information back and forth between VMs. The distributed |
| collections use the remote method invocation built on top of a {@link |
| org.apache.geode.tcp.TCPConuit} to access elements in remote |
| collections. GemFire distirbution uses underlying technologies such |
| as JavaGroups, and sockets to implement data transfer. |
| |
| <P> |
| |
| The vast majority of these APIs are internal. However, the user is |
| exposed to concepts such as the "distribution manager" and the fact |
| that multicast networking or "locators" are used to discover the other |
| members of the distributed group. The user-level configuration is |
| grouped together in the {@link |
| org.apache.geode.distributed.DistributedSystem} class which |
| provides a "connection" or entry point to the distributed system. |
