    • A method for rejecting received SIP messages which are redundantly retransmitted used in a Session Initiation Protocol (SIP) application architecture. In one embodiment, the method comprises: forwarding all the messages transmitted from a SIP application server to a SIP terminal, and dropping all the received SIP messages redundantly retransmitted from the SIP terminal to the SIP application server according to the transmission direction of said SIP messages; and correspondingly replying to the dropped SIP messages according to the message type thereof. The present invention also provides a corresponding retransmission rejection device and a network device comprising the same, and further provides a method and device for rapidly rejecting redundantly retransmitted SIP messages in the case where the memory space is limited. The present invention can be applied to a network device such as a SIP stateless proxy at a front end of a SIP application server cluster.
    • 一种用于拒绝在会话发起协议(SIP)应用架构中使用的冗余重传的接收到的SIP消息的方法。 在一个实施例中,所述方法包括:将从SIP应用服务器发送的所有消息转发到SIP终端,并且根据所述SIP消息的传输方向将从SIP终端冗余重发的所有接收的SIP消息转发到SIP应用服务器 ; 并根据其消息类型相应地回复丢弃的SIP消息。 本发明还提供了相应的重传拒绝设备和包括该重传拒绝设备的网络设备,并且还提供了在存储器空间有限的情况下快速拒绝冗余重传的SIP消息的方法和设备。 本发明可以应用于SIP应用服务器集群的前端的诸如SIP无状态代理之类的网络设备。

    • In computer multimedia technology, a system, method and computer program product for optimizing images and transmission of images of a web-page transmitted over the Internet and furthermore, optimizing images of a web page on a network server. The method includes detecting the images in the web page to determine the relationship among the images; in response to the determination of the relationship among the images, combining two or more related images into a combinational image; and updating the web page to replace references to the related images with a reference to the combinational image. By optimizing web page images, the server's work required for handling heavy amount of HTTP requests in transmitting the web page images is decreased and the bandwidth requirement for transmitting the web page images is reduced. The quality of the original image is not lowered. And there is no need to make any change to the operation at the client side.
    • 在计算机多媒体技术中,一种用于优化通过因特网传输的网页的图像和图像传输的系统,方法和计算机程序产品,此外,优化网络服务器上的网页的图像。 该方法包括检测网页中的图像以确定图像之间的关系; 响应于确定图像之间的关系,将两个或更多个相关图像组合成组合图像; 并且通过参考组合图像来更新网页以替换对相关图像的引用。 通过优化网页图像,服务器在传输网页图像时处理大量HTTP请求所需的工作减少,并减少了传送网页图像的带宽需求。 原始图像的质量不会降低。 而客户端的操作无需改动。
