5. Part 1: Overview The Connectivity Wheel Network Categories Networking & Connectivity APIs

6. The Connectivity Wheel Circuit Switched Data (e.g. GSM, CDMA) Packet Data (e.g. GPRS, 1xRTT) SMS 802.11 Desktop Pass-Through Bluetooth TCP/IP WAP Cable Replacement

7. Network Categories Personal Area Network (PAN) Wired – USB, serial Wireless – Bluetooth, Infrared Local Area Network (LAN) Wired – Ethernet (TCP/IP), Token-ring Wireless – 802.11b “WiFi”, 802.11a Wide Area Network (WAN) Wired – Plain Old Telephone System (POTS), The Internet Wireless – Mobile phone networks (GSM/GPRS/CDMA)

8. Networking APIs (1/8) Windows Sockets 2.2 TCP/IP connections No asynchronous support (Windows message-based support) IrDA connections Bluetooth connections Differences from previous versions Multiple transport protocols TCP/IPv4TCP/IPv6 Multicast support Overlapped I/O with scatter/gather Secure socket

9. Networking APIs (2/8) Network Support Windows Internet (WinInet) Services HTTP clients FTP clients No Gopher protocol support AutodialPassport Connection Manager Container for network connection and configuration information Supports connection policy

10. Networking APIs (3/8) ActiveSync Service Providers Synchronization of device data with desktop Examples: Desktop Outlook with Pocket Outlook Desktop database with device database Elements COM-based DLL on desktop COM-based DLL on device Enabled with registry settings

11. Networking APIs (4/8) Remote API (RAPI) Available when device is connected via ActiveSync Access to device data File system Registry CE property databases Load & run device-side exucutables: CeCreateProcess – run program (.exe) file CeRapiInvoke – load library (.dll) on device

12. Networking APIs (5/8) Web services Formerly known as “XML Web services” Client/Server Mechanism Remote Procedure Call (RPC) SOAP-compliant XML Sent via HTTP/SMTP ports Device Side.NET Compact Framework supports Web service clients Server Side ASP.NET supports Web service servers

13. Networking APIs (6/8) Mobile Phone Assisted Telephony Phone API Telephony API (TAPI) Extended TAPI Wireless Application Protocol (WAP) Short Message Service (SMS) Subscriber Identity Module (SIM) Manager

14. Networking APIs (7/8) User Interface Support NETUI – dialog box library GetIPAddressConnectionDialogDisconnectDialogGetUsernamePassword Connection Setting Applet… CreateProcess(L”remnet.exe”, …) Summon ActiveSync: CreateProcess(L”repllog.exe /remote”, …)

15. Networking APIs (8/8) Miscellaneous Data Security Cryptography API Digital Certificates (X.509) Secure Socket Layer (SSL 2.0 and 3.0) Private Communications Technology (PCT) Protocol 1.0 Dial-Up Networking A.k.a. “Remote Access Service” (RAS) Call ISP over modem Establish PPP / SLIP connections Use Connection Manager instead

16. Part 2: Connectivity Scenarios Personal Area Network Local Area Network Wide Area Network

17. Personal Area Network ActiveSync Connectivity PAN / Direct connection USB, serial Infrared, Bluetooth Passthrough Network connection to device in cradle Supports HTTP, HTTPS, IMAP, FTP, and POP3 Does not support UDP, ICMP, or PPTP Reference – article by Andreas Sjöström: http://www.microsoft.com/mobile/developer/tech nicalarticles/passthrough.asp http://www.microsoft.com/mobile/developer/tech nicalarticles/passthrough.asp Use ActiveSync 3.7 for Windows Mobile devices

18. Personal Area Network Developer Support ActiveSync supports Download / deployment Debugging *Tip* Developers can speed up download & debugging with an ActiveSync network connection Emulator Support ActiveSync Requires network virtual switch Refer to eVC++ 4.0 documentation

19. Local Area Network ActiveSync First: establish partnership via direct connection Can synchronize over any LAN Wireless: WiFi (802.11b), 802.11a Wired: Ethernet, Token-ring Exchange Server ActiveSync to server *Tip* Developers can speed up download & debugging with an ActiveSync network connection (did I already say that?!?)

20. Local Area Network ”My Work Network” Can connect via modem Virtual Private Network Need host name –or- IP address VPN Types: IPSec/L2TP – need certificate –or- pre-shared key PPTP – need user name/password Can have proxy settings HTTPWAP Secure WAP

21. Local Area Network What is it good for? Access to any IP-enabled network service or server Fun with HTML Browse WWW, local web servers Fun with XML Web service client Web service server Fun with TLAs (three-letter acronyms…) FTP, SSL, VPN, PPTP Network PPP Network redirector - SMB protocol File Servers Print Servers

22. Local Area Network Connect Visual Studio.NET Use ActiveSync Establish partnership via USB/serial Download & Run Starts device-side conmanclient.exe Configure TCP/IP Transport Tools->Options… [Device Tools] [Devices] “Pocket PC Device”, Click [Configure…] Options: Auto IP address Static IP address Set static address on device IP address from ActiveSync

23. Local Area Network Download/Debug – eVC++ (no DHCP) Establish partnership via USB/serial Static IP address on desktop Static IP Address on smart device Set WINS address to desktop IP address Start->Settings-> [Connections] [Network] [Adapters] [Name Servers]

24. Local Area Network Download/Debug – eVC++ (w/ DHCP) Desktop-Side Enable network connections Connect via USB/serial Device-Side Enable network connections in ActiveSync Enable DHCP for network adapter Attach network adapter Might need to reset device Connect to Network WiredWireless

25. Public Network Support Connect via: Dial-in modem Internet PPTP connection ActiveSync WAN Connection VPN / PPTP connection to desktop Exchange Server ActiveSync to server Networks Internet – WWW, http, https: WAP – wsp://, wsps: GSM / GPRS / CDMA

26. Public Mobile Phone Network WAP Protocol Wireless Datagram Protocol (WDP) SMS or UDP Transports Application Wake up (PPC2003 only) WDP Phase 1 support datagrams may originate from the internet

27. Public Mobile Phone Network Short Message Service (SMS) Used for short messages Length is air link dependent Capable of message concatenation APIs #include #include SmsOpen(…);SmsSendMessage(…);SmsClose(…);

28. Part 3: Connection Manager Overview Network Model Configuration Configuration Service Providers (CSPs) API Support

29. Connection Manager Overview Umbrella for Network Address Resolution Voice Data – Internet, WAP, etc. Configuration Service Providers (CSP) Manage service-specific, low-level settings GPRS settings, Data networks, URL mapping Connections for: PPP, Proxies, VPN, WiFi Decide optimal route for connections Based on ‘cost’ criteria provided by CSPs Can manage multi-hop connections

30. Connection Manager Network Model The Internet My Corporate Network WAP Network VPNProxy WAPGateway Cingular ISP Earthlink ISP MS Redmond RAS MS Paris RAS Yahoo.com msw mail.earthlink.net red-msg-06 wap.ananova.com

31. Connection Manager Configuration (1/2) Who can configure End user Corporate IT Dept Mobile phone service provider Default Networks The Internet Work The WAP Network Secure WAP Network Pocket PC Adds My Work Network My ISP

32. Connection Manager Configuration (2/2) Burn into device ROM Send in CAB provisioning format (.cpf) file Install in cradle using rapiconfig.exe C> rapiconfig mydoc.xml Send using Wireless Application Protocol (WAP) Push Message Over-the-air (OTA) protocol Provisioning XML File <wap-provisioningdoc> </wap-provisioningdoc>

33. Connection Manager Configuration Service Providers (CSP) Connection Manager Engine Voice RASProxyPPTPGPRS etc Planner ConfigurationManager Connection Manager UI XMLProvisioningDocument URLMapper Application CSPs

34. Connection Manager API Support (1/2) ConnMgrMapURL() Fetch preferred network for a given URL Allows applications to query for network policy Default mapping: *:\\*.*\ - The Internet *:\\*\ - Private network (intranet) wsp:\\ - WAP network wsps:\\ - Secure WAP network

35. Connection Manager API Support (1/2) ConnMgrEstablishConnection() Creates asynchronous request for connection ConnMgrConnectionStatus() Query connection status ConnMgrEstablishConnectionSync() Creates synchronous request for connection ConnMgrReleaseConnection() Disconnect when finished using network
