摘要:
A method for partitioning Web pages of a Web site into graphic elements and technical elements to enable efficient updating of the Web site. Graphic elements of a Web page are defined and a plurality of technical page element sets for respectively formatting the Web page in accordance with the technical page element sets are defined. The graphic elements of the Web page are converted into a stylesheet using a content-to-stylesheet generator. The Web page is then processed using the stylesheet in accordance with one of the technical page element sets to obtain a formatted Web page in accordance with the one technical page element set. The stylesheet can be compatible with a version of XSL (extensible stylesheet language). The formatted Web page is subsequently provided to a user via a server application. Efficient updating of the Web site is enabled by partitioning the graphic design elements, which define a look and feel for the Web page, from the technical page elements, which define the technical reliability of the software objects, scripts, macros, and the like. The partitioning allows the graphic design elements and the technical elements to be changed and updated more independently.

A method for tracking a user flow of Web pages of a Web site to enable efficient updating of the hyperlinks of the Web site. A Web page is accessed out of a plurality of Web pages of a Web site. A set of actions available to a user are determined for the Web page. A set of the next pages linked to the Web page are determined for the Web page. A set of rules are defined that modify the set of actions available to the user or the set of next pages linked to the Web page in accordance with an identity of the user. The set of actions, the set of next pages, and the set of rules are stored in a table data structure for the Web page to track a user flow of the Web page. The table data structure enables the user flow of the Web page to be changed by altering the corresponding set of rules in the table data structure for the Web page. Similarly, the user flow can be changed by altering the set of actions available to the user, or by altering the set of next pages linked to the Web page in the table data structure for the Web page. A plurality of table data structures can be generated for each of the plurality of Web pages of the Web site, and the table data structures can be stored in a matrix to track a user flow of the entire Web site.

Methods and systems are provided for steering network packets. According to one embodiment, a dynamically configurable steering table is stored within a memory of each network interface of a networking routing/switching device. The steering table represents a mapping that logically assigns each of the network interfaces to one of multiple packet processing resources of the network routing/switching device. The steering table has contained therein information indicative of a unique identifier/address of the assigned packet processing resource. Responsive to receiving a packet on a network interface, the network interface performs Layer 1 or Layer 2 steering of the received packet to the assigned packet processing resource by retrieving the information indicative of the unique identifier/address of the assigned packet processing resource from the steering table based on a channel identifier associated with the received packet and the received packet is processed by the assigned packet processing resource.

Methods and systems are provided for steering network packets. According to one embodiment, a mapping associates a processing resource with a network interface module (netmod) and/or a number of line interface ports included within the netmod. In one embodiment, the mapping is configurable within the processing resource and pushed to the netmod. The netmod uses the mapping to steer network packets to the processing resource when the packets conform to the mapping. The mapping may be additionally used to identify a specific process that is to be performed against the packets once the processing resource receives the steered packets from the netmod.

Methods and systems are provided for bridging heterogeneous media packets using a single processor resource having a virtual bridge. Network interfaces associated with heterogeneous media channels relay network packets to the virtual bridge. The virtual bridge accesses metadata associated with the relayed network packets and translates the network packets between media formats. The translated network packets are then relayed to an appropriate network interface. In one embodiment, the virtual bridge is dynamically configurable within the processing resource.

Methods and systems are provided for steering network packets. According to one embodiment a method is provided for steering incoming network packets. Each network packet processing resource of a network routing/switching device is dynamically assigned to one or more network interfaces of the network routing/switching device. Each of the network packet processing resources includes one or more processing elements and a memory. Incoming network packets received by the network interfaces are steered to an appropriate network packet processing resource based on the dynamic assignment.
摘要:
A system and method for dynamically selecting a level of compression to be applied to data to be served to a client. The level of compression may be selected on the basis of one or more factors, such as: the bandwidth of a communication link between the client and a server, the amount of data requested by the client, the workload of the server, whether the data are cacheable, etc. The server can readily obtain information such as the amount of requested data and the available CPU time on the server. To determine the bandwidth, the server may conduct a test transfer of a known amount of data to or from the client, or consult a database identifying known or expected bandwidths for specific client connections (or addresses). Based on the selected factor(s), the server dynamically selects a level of compression for the data.

Techniques for automatically modifying behavior of a compiled application include receiving a first set of compiled instructions for the application. The first set of compiled instructions is modified to generate a modified set of compiled instructions. Modifying the first set of compiled instructions includes inserting a new set of one or more instructions for invoking a first routine that provides new behavior. The first routine is not part of the first set of compiled instructions. These techniques allow an administrator to automatically instrument compiled code of an application to provide new behavior for the application without taking the application offline for substantial periods of time. In particular, the techniques allow a service provider to automatically instrument existing applications, components, and sub-components to measure and respond to server-side performance without taking the applications offline.

A method and apparatus for detecting peer traffic based on a heuristic model and deep packet inspection is described. A suspect set of peer packets is detected using a heuristic model. From the suspect set of peer packet, a set of verified peer packets is detected using deep packet inspection. The set of verified peer packets is processed according to the peer processing policy, while the non-verified peer packets is processed according a non-peer policy. Furthermore, the statistics are generated from the set of suspect peer packet. These statistics are used to update the heuristic model.

Methods and systems for bridging network packets transmitted over heterogeneous media channels are provided. According to one embodiment, a network-computing device comprises multiple network interfaces (netmods) and a shared processing resource. The shared processing resource executes a virtual bridging application representing a single bridging domain for all network packets received by the network-computing device. A translation data structure defines translations between a first framing media format and an intermediate format and between the intermediate format and a second framing media format. If the virtual bridging application determines a network packet is to be relayed between a netmod operable to receive network packets encapsulated within the first framing media format and a netmod operable to transmit network packets encapsulated within the second framing media format, then it uses the translation data structures to translate the network packet before relaying the network packet.
