为了达到低延时、高吞吐量、容错的目标, OS 的网络设置和 Geode 将需要合理地配置. 如下章节是官方推荐的配置.

IPv4 vs. IPv6

By default默认情况下, Geode uses Internet Protocol version 4 (IPv4). Testing with Geode has shown that IPv4 provides better performance than IPv6. Therefore, the general recommendation is to use IPv4 with Geode. However, Geode can be configured to use IPv6 if desired. If IPv6 is used, make sure that all Geode processes use IPv6. Do not mix IPv4 and IPv6 addresses.使用 IPv4. 通过测试 Geode 表明 IPv4 的性能要优于 IPv6. 因此, 通用的推荐是使用带有 Geode 的 IPv4. 然而, 如果需要的话, Geode 也能配置使用 IPv6. 一旦使用 IPv6 , 请确保所有的 Geode 进程都使用 IPv6. 不要使用IPv4 和 IPv6 混合地址.

注意: 对于 Geode 地址使用 IPv6, 设置如下的 Java 属性Note: to use IPv6 for Geode addresses, set the following Java property: java.net.preferIPv6Addresses=true

TCP vs. UDP

Geode supports the use of both TCP and UDP for communications. Depending on the size and nature of the Geode system as well as the types of regions employed, either TCP or UDP may be more appropriate支持TCP和 UDP 两种通信方式. 依赖于 Geode 系统的大小和特性, 以及 Region 的类型来选择 TCP 还是 UDP 通信.

TCP 通信

TCP (Transmission Control Protocol) provides reliable in-order delivery of system messages. Geode uses TCP by default for inter-cache point-to-point messaging. TCP is generally more appropriate than UDP in the following situations:
