Class HTTPMUSocket

java.lang.Object

org.cybergarage.upnp.ssdp.HTTPMUSocket

Direct Known Subclasses:

SSDPNotifySocket, SSDPSearchSocket

public class HTTPMUSocket
extends Object

Multicast UDP socket implementation for SSDP communication.

This class provides multicast socket functionality specifically designed for SSDP operations in UPnP networks. It handles both sending and receiving multicast UDP packets for device discovery and advertisement.

Key features:

• Multicast socket management and configuration
• SSDP multicast address handling
• TTL (Time To Live) configuration
• Network interface binding
• Packet sending and receiving

This class is used by SSDP components to send multicast discovery messages and receive multicast advertisements from UPnP devices, enabling the core device discovery functionality in UPnP networks.
