企业移动消息应用的起点:E-Mail E-Mail 已经是企业的核心应用 已经存在多种成熟设备和解决方案
07/11/2018 企业移动消息应用的起点: 已经是企业的核心应用 已经存在多种成熟设备和解决方案 Exchange Server 2003 是第一个集成的解决方案 结合ISA可以提供更高的可用性和管理性 结合IT策略可以实现更高的安全性 除了微软和RIM,目前市场上至少还有四家公司提供各自的手机push 系统,它们分别是:Good Technology,Nokia,Seven以及Visto。另外,DataViz在他的RoadSync产品中支持微软的服务,该产品可以工作在 Symbian和Palm平台上。在手机移动电子邮件市场,也出现了一些企业间的合并案例,比如Seven在收购了Commtag后,又收购了 Smartner。 © 2004 Microsoft Corporation.

07/11/2018 ActiveSync 访问机制 AirSync HTTP (basic authentication) [SSL] (preferred) IIS MASSYNC.DLL ISAPI DAVEX.DLL ISAPI Front End Server Back End Server DS_ACCESS Active Directory Read User Properties & obtain Kerberos TGT WebDAV HTTP (Integrated authentication) Clear Exchange disables certain services on FE servers. The idea is that FE servers should only be used to proxy client requests to BE servers (and possibly relay SMTP traffic). Since they sit in a DMZ, FE servers should not perform other tasks. The services which are disabled are: DSProxy Offline Address List Generation Recipient Update Service Mailbox Cleanup Agent Therefore before converting a server to a FE (or before applying SP2 to a FE) you should move the Offline Address List Generation and the Recipient Update Service to other servers. Also, any system folders, such as Free and Busy, Offline Address Book and Organisational forms should also be moved to a different server. Remember, that Public Stores should not exist on a FE server. Back End Server Files On a BE server IIS redirects requests to the following DLL files: DAVEX.dll – This is for OWA requests. POP3BE.dll – This is for POP3 requests. IMAP4BE.dll – This is for IMAP4 requests. Front End Server Files When a server is converted to a FE all that happens is the FE DLLs are activated and the BE DLLs are unused. The FE DLLs are: EXPROX.dll – For OWA requests. POP3FE.dll – For POP3 requests. IMAP4BE.dll – For IMAP4 requests. 12 © 2004 Microsoft Corporation. All rights reserved. This presentation is for informational purposes only.

直推技术(Direct Push) Direct Push Mail 技术原理 (心跳时间为 15min)
07/11/2018 直推技术(Direct Push) Direct Push Mail 技术原理 (心跳时间为 15min) Device : 如果我在15分钟内有邮件请告诉我,否则告诉我“没有邮件”. Time = 0 min Server: “没有邮件” Time = 15 min Device : 如果我在15分钟内有邮件请告诉我,否则告诉我“没有邮件”. Time = 15 min Server: “你有新邮件” Time = 23 min Point to make here is about customer firewall and IIS timeouts and the open HTTP request. The WM client sends a request to be honored by the Exchange Server of 15 minutes, by default. The firewall and IIS timeout should be set to at least 15 minutes for this to work properly. Example, MSIT has slowly fine tuned to the point where they are at 30 minutes, today – with 2 front end servers handling all traffic for RPC/HTTP, OWA, IMAP, POP and Sync. Anywhere from unique sync users on thoise two servers. Not all running the new IP notification. Additional data will be available later on this metric. Heartbeat: Device sends ping to server to generate IP connection Some bandwidth overhead incurred in keeping IP connection to Exchange alive “always on“ Assuming heartbeat every 15min, incremental overhead required to keep IP connection “alive“: 370 Bytes/heartbeat x 4 heartbeats/hour x 24h x 30days = 1,06MB (No consideration to block rounding) Windows Mobile Device with MSFP Device : 给我邮件 Time = 23 min Server running Exchange 2003 SP2 Heartbeat: 370 Bytes/heartbeat x 4 heartbeats/hour x 24h x 30days = 1,06MB (No consideration to block rounding) © 2004 Microsoft Corporation.
