In this paper, we present a novel hardware-based XML/XPath broker architecture for content-based Publish/ Subscribe systems. Our broker architecture includes processors to parse XML published content and XPath subscriptions, a matching engine to match subscriptions against publications, and components to forward either subscriptions or notifications based on content. While software techniques are...
This paper presents a reconfigurable architecture for the session initiation protocol (SIP). SIP is a protocol used primarily to establish point-to-point sessions between users for multimedia communication. Furthermore it increases the performance of Internet applications and overall efficiency. However, most existing SIP solutions are entirely software based. SIP performance can be enhanced by executing...
The need for efficient XML parsing becomes a key requirement in the underlying technologies of Web information and distributed systems. Even though new software-based XML parsing techniques have been studied to improve XML processing, the verboseness nature of XML does not help much to achieve substantial improvement. Hardware-based solutions can be an obvious choice to parse XML in a very efficient...
With the widespread popularity of XML, many communication and multimedia standards are being developed based completely or partially on XML. The session initiation protocol is a signaling mechanism - frequently used for multimedia applications - that comprises XML-based ldquopresencerdquo information particularly useful in instance messaging.The process of XML parsing and serialization is needed repeatedly...
