Class HTTPUSocket

java.lang.Object

org.cybergarage.upnp.ssdp.HTTPUSocket

Direct Known Subclasses:

SSDPSearchResponseSocket

public class HTTPUSocket
extends Object

UDP socket implementation for SSDP (Simple Service Discovery Protocol) communication.

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

Key features:

• UDP unicast socket management
• IPv4 and IPv6 support
• Packet sending and receiving
• Timestamp tracking for received packets
• Network interface binding

This class is used by SSDP components to send discovery messages (M-SEARCH) and receive device advertisements (NOTIFY messages) over UDP multicast and unicast communication.
