In the</p><p>ON period, users send fixed size packet in fixed time and generate voice data. In the OFF</p><p>period, no data is generated.</p><p> Various applications such as voice, video and data, form video meeting service frames</p><p>through different protocol stacks.</p><p>Course Name P-15</p><p>Confidential Information of Huawei.

The measurement for HTTP</p><p>services indicate that large web pages are formed by relatively small objects. That is</p><p>to say, each page consists of some web embedded objects, such as main page,</p><p>embedded image, and embedded Java program.</p><p> In a package call, package service characteristics are related to the Web server and</p><p>browser HTTP version. Currently, HTTP/1.0 and HTTP/1.1 are used. The maximum</p><p>difference of the two versions are that the TCP connection of transmission layer of</p><p>main object and embedded object are different.</p><p> In HTTP/1.0, each main object and embedded object of the Web page download use</p><p>different TCP connections. In the browsing process of most customer terminals,</p><p>embedded objects use multiple TCP connections at the same time, which is called</p><p>HTTP/1.0 - burst mode transmission. Meanwhile, the maximum TCP number can be</p><p>connected is configurable. Most browser is set to 4. When the embedded object exceeds</p><p>the number, a new TCP connection is set up, and the original connection is built. TCP</p><p>overhead and congestion control is based on each object.</p><p> In HTTP/1.1, consecutive TCP connections are used to download object. That is, the</p><p>transmission object connected in serial on a single TCP connection is called HTTP/1.1 --</p><p>consecutive mode transmission. TCP overhead and congestion control are based on</p><p>each connection.</p><p>Course Name P-16</p><p>Confidential Information of Huawei.

The outlook transmission is dependent</p><p>on remote procedure call (RPC) and uses complex protocols. When invoking the</p><p>Outlook, there are 11 activated TCP connections. Each email processing consists of</p><p>multiple MAPI segment elements. Each MAPI segment processing can be divided into</p><p>more specific segments</p><p>Course Name P-17</p><p>Confidential Information of Huawei.
