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)

  1. Addressing : IP assignment on any network (AutoIP)
  2. Discovery : Of services/devices (SSDP)
  3. Description : Syntax for devices/services (SCPD/DDD)
  4. Control : Of device services (SOAP)
  5. Eventing : Updates of variables (GENA)
  6. 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
