Because nonblocking channels give no indication when a message has been fully read , we are forced to handle this at the protocol layer 因为当全部读取消息时,非阻塞通道没有给出任何提示,所以强制我们在协议层处理这一情况。
Unlike the dialog protocol layer , the adjacent protocol layer is aware of the network transport used , and formats the message fragments appropriately 与对话协议层不同,相邻broker协议层知道所用的网络传输和相应的消息片段格式。
The obex protocol layer is implemented above the rfcomm layer and is useful when you want to transfer data as an object , such as files Obex协议层是在rfcomm层上面实现的,如果想把数据以对象(例如文件)的形式传输,那么obex很有用。
I explain each protocol layer associated with the written code , and give the data flow of the implemented protocol at the end of each chapter 在描述蓝牙规范时,对各个协议层都结合具体实现时开发的代码予以说明并在讲述每层协议的章节最后给出了该层协议栈实现时的数据流程。
The dialog protocol layer generates sequence numbers for messages , generates acknowledgement messages , delivers messages to the proper queues , and fragments and reassembles messages 对话协议层生成消息的序列号、生成确认消息、向正确的队列传递消息并对消息进行分段和重组。
In this article you ve toured the linux device driver and network protocol layers for popular wireless technologies including wlan , bluetooth , gprs , gsm , and irda 在本文中,您浏览了是针对包括wlan 、 bluetooth 、 gprs 、 gsm和irda在内的流行的无线技术的linux设备驱动程序和网络协议层。
When the dialog protocol layer receives two messages on the same dialog with the same sequence number , the dialog protocol layer considers the messages to be duplicates and discards one 当对话协议层对同一对话收到两个序列号相同的消息时,对话协议层认为这两个消息是重复的并会放弃其中的一个。
On the basis of above knowledge , we comprehend the relations among the different bluetooth protocol layers and the principle of data transferring between two bluetooth protocol layers 在此基础上明确了蓝牙协议层之间的关系以及通过高层协议实现对低层传输协议的内部操作的原理,为开发简单的蓝牙通信系统奠定了基础。
4 . the application sublayer , which converts the information format between the user and the lower protocol layer . 5 . the user sublayer . the key part , function block is the assurance of the interoperation of it 这部分的重点内容是功能块,它是ff实现互可操作的保证,也是ff不同于其他总线的独特之处,作者作了详尽的分析。
In this thesis , research has been carried on in several aspects of the principle of voip and the h . 323 protocol which is used broadly , such as network structure of voip , protocol layers of voip , rtp / rtcp 323协议。这其中对voip的网络结构、 voip的网络协议、 voip的系统设备、 voip的业务流程、实时传输和控制协议等要素进行了广泛的讨论。
