1 概况

1.1 基础协议

SOAP(Simple Object Access Protocol)
SSDP(Simple Service Discovery Protocol)
GENA(Generic Event Notification Architecture)
SCPD/DDD(Service Control Protocol Description)

1.2 UPnP Device Architecture (UDA)

Addressing : IP assignment on any network (AutoIP)
Discovery : Of services/devices (SSDP)
Description : Syntax for devices/services (SCPD/DDD)
Control : Of device services (SOAP)
Eventing : Updates of variables (GENA)
Presentation : Access to device HTML page

1.3 Device Control Protocols (DCPs)

APIs for various device functionality
Described using SCPD syntax and UDA protocols

1.4 UPnP Architecture Diagram

Standard Services           Device Control Protocols

Common Architecture         3.Control; 4.Eventing; 5.Presentation
                            2.Description
                            1.Discovery
                            0.Addressing

Base                        HTTP, XML, TCP, UDP, IP

2 协议

2.1 术语

NT (Notification Type)
NTS (Notification Sub Type)
USN (Unique Service Name)
UDN (Unique Device Name)
SID (Subscription IDentifier)

2.2 发现(Discovery)

2.2.1 Advertising

多播内容:

1 time / service type with NT == service type
1 time / device type with NT == device type
1 time / device with NT == device UUID
1 time with NT == upnp:rootdevice

如:

NOTIFY * HTTP/1.1
HOST: 239.255.255.250:1900
CACHE-CONTROL: max-age = seconds until advertisement expires
LOCATION: URL for UPnP description for root device
NT: search target
NTS: ssdp:alive
USN: advertisement UUID

2.2.2 Searching

多播内容:

ST one of:
- Service type, Device type, Device UUID
- upnp:rootdevice
- ssdp:all

如:

M-SEARCH * HTTP/1.1
MX: 3
MAN: "ssdp:discover"
HOST: 239.255.255.250:1900
ST: ssdp:all

2.2.3 Responding

单播内容:

1 time for each NT that matches
Simple service name matching

如:

HTTP/1.1 200 OK
Location: http://172.16.5.92:1074/
Cache-Control: max-age=1800
Server: UPnP/1.0 DLNADOC/1.50 Platinum/1.0.4.11
EXT:
USN: uuid:2b82a0e2-27b0-b245-80bd-8922a9494b47::upnp:rootdevice
ST: upnp:rootdevice
