SIG MESH Profile 2.3.11 Features 翻译

The functionality of nodes is determined by the features that they support. All nodes have the ability to transmit and receive mesh messages. Nodes can also optionally support one or more additional features:

节点的功能由它们所支持的特性决定。所有节点都具有传输和接收MESH消息的能力。节点也可以选择支持一个或多个附加功能:

• Relay feature – the ability to receive and retransmit mesh messages over the advertising bearer to enable larger networks
• 中继功能-能够接收和转发广播监听之上的MESH信息，以扩大网络
• Proxy feature – the ability to receive and retransmit mesh messages between GATT and advertising bearers
• 代理功能-能够在GATT和广播监听之间接受和转发MESH信息
• Low Power feature – the ability to operate within a mesh network at significantly reduced receiver duty cycles only in conjunction with a node supporting the Friend feature.
• 低功耗工-和支持朋友功能的节点结合之后，能在MESH网络中明显降低接收占空比的情况下进行工作
• Friend feature – the ability to help a node supporting the Low Power feature to operate by storing messages destined for those nodes
  
• 朋友功能-帮助一个低功耗节点存储发给他们的信息

A node that supports a feature may have that feature enabled or disabled, and the feature, when enabled,may be or may not be in use.

支持某个特性的节点可以启用或禁用该特性，启用该特性时，可以使用该特性，也可以不使用该特性。

A node supporting the Relay feature may have this feature disabled, but it would still support the Relay feature, it is just that it is not performing the functionality required by that feature. A node that supports the Relay feature and has the Relay feature enabled is known as a Relay node. 

支持中继功能的节点可能禁用了此功能，但它仍然支持中继功能，只是它没有执行该功能所需的功能。支持中继功能并启用中继功能的节点称为中继节点。

A node supporting the Low Power feature cannot have this feature disabled and must establish a friendship with another node supporting the Friend feature before it can use the Low Power feature to reduce receiver duty cycles. A node that supports the Low Power feature and has a friendship with a node that supports the Friend feature is known as a Low Power node.

支持低功耗特性的节点不能禁用此特性，必须与另一个支持Friend特性的节点建立友谊，然后才能使用低功耗特性来减少接收占空比。支持低功耗特性的节点与支持Friend特性的节点有友谊关系，称为低功耗节点。

A node supporting the Friend feature may have this feature disabled, but it would still support the Friend feature, it is just that it is not performing the functionality required by that feature. A node that supports the Friend feature, has the Friend feature enabled, and has a friendship with a node that supports the Low Power feature is known as a Friend node.

支持好友功能的节点可能禁用了此功能，但它仍然支持好友功能，只是它没有执行该功能所需的功能。支持朋友功能的节点启用了朋友功能，并且与支持低功耗功能的节点建立了友谊关系，这种节点称为朋友节点。
