正在进行多播，可能有Wi-Fi Direct的？ [英] Is multicasting possible with Wi-Fi direct?

问题描述

我有点困惑在安卓ICS新的Wi-Fi直特点：是有可能创造一个P2P组的多的设备，并从源节点到发送组播数据包其他的同龄人？

不幸的是，我没有这方面的为Wi-Fi直接启用任何设备，所以我只能浏览，我在网上找到的例子。在这些例子中，我只能找到同行estabilishing 1对1的连接。因此，在多播可能吗？

解决方案

  

是否有可能与多个设备创建一个P2P组？

基于产业白皮书和技术规范

，是的，它可以创建一个组，多台设备，你将有一个一对多的连接，一组所有者（GO）和许多客户。

  

从源节点发送组播数据包到其他同龄人？

根据技术规格，在GO应充当DHCP服务器，并提供一个IP地址连接的客户端（应该充当DHCP客户端）。每个设备都可以很容易地知道自己的IP和GO的IP，所以应该可以使用地址255.255.255.255做广播

对于一个适当的多播，我不知道，我想这取决于创建的DHCP服务器的功能。

I'm a bit confused about the new Wi-Fi direct feature in Android ICS: is it possible to create a p2p group with multiple devices, and send multicast packets from a source peer to the other peers?

Unfortunately, I don't have any devices that are Wi-Fi direct enabled, so I can only browse the examples that I find online. In these examples, I could only find peers estabilishing 1-on-1 connections. So, is multicasting possible?

解决方案

Is it possible to create a p2p group with multiple devices ?

Based on the Industry white paper and the technical specs, yes it is possible to create a group with multiple devices, you will have a one-to-many connection, one Group Owner (GO) and many clients.

Send multicast packets from a source peer to the other peers?

Based on the technical specs, the GO shall act as a DHCP server and provide an IP address to the connected clients (which should act as a DHCP client). Each device can easily know its own IP and the GO's IP, so it should be possible to do a broadcast using the address 255.255.255.255.

Regarding a proper multicast, I am not sure, I guess it depends on the capabilities of the DHCP server created.
