IP地址将不同的物理地址统一起来,从而将物理地址隐藏起来,上层软件使用IP地址标识结点。但是,两台计算机只有在知道彼此的物理地址时才能进行通信。 IP数据包常通过Ethernet发送。Ethernet设备并不识别32位IP地址,它们是以48位MAC地址传输Ethernet数据包的。因此,IP驱动器必须把IP目的地址转换成Ethernet网络目的地址。这两种地址之间存在着某种静态的或动态的映射,通常需要查看一张表来进行这种映射。地址解析协议(Address Resolution Protocol,ARP)就是用来确定这些映象的协议。 ARP工作时,送出一个含有所希望的IP地址的Ethernet广播数据包。目的地主机(或另一个代表该主机的系统)以一个含有IP和Ethernet地址对的数据包作为应答。发送者将这个地址对高速缓存起来,以节约不必要的ARP通信

Description: This program demonstrates a half-duplex 9600-baud UART using // Timer_A3 using no XTAL and an external resistor for DCO ROSC. DCO used for // TACLK UART baud generation. The program will wait in LPM4, echoing back // a received character using 8N1 protocol. On valid RX character, the // character is echoed back. // Using a 100k resistor on ROSC, with default DCO setting, set DCOCLK ~ 2MHz. // ACLK = n/a, MCLK = SMCLK ~2MHz DCOCLK

Atmel’s AT91SAM7FP105 is a low pincount FingerChip processor based on the 32-bit ARM RISC processor. It features a on-chip biometric engine performing enrollment verification and identification, an internal record cache of up to 25 records and a secure command protocol over USB, SPI, UART. This protocol enables an external host system or processor to control the onchip bioengine functions, manipulate the record cache, and securely export record cache records for external storage. Together with the FingerChip sensor device AT77C104B, it forms an embedded, secured biometric turnkey solution.

摘 要 基于IP的语音、数据、视频等业务在NGN网络中所面临的一个实际困难就是如何有效地穿透各种NAT/FW的问题。对此,会话初始化协议SIP以往的解决方法有ALGs,STUN,TURN等方式。本文探讨了一种新的媒体会话信令穿透NAT/FW的解决方案—交互式连通建立方式(ICE)。它通过综合利用现有协议,以一种更有效的方式来组织会话建立过程,使之在不增加任何延迟同时比STUN等单一协议更具有健壮性、灵活性。本文详细介绍了ICE算法,并设计一个实例针对SIP信令协议穿透Symmetric NAT流程进行了描述,最后总结了ICE的优势及应用前景。
