摘要:
A computer system provides content to a client device such as a handheld wireless telephone by identifying the client device as a limited-display client device, receiving a request from the client device for hypertext content (e.g. content in HTML form), and generating a reduced-size version of the requested hypertext content. Based on the identification of the client device as a limited-display client device and in response to the request, the reduced-size version of the hypertext content is returned to the client device. The reduced-size version of the hypertext content may be generated by removing information from the hypertext content which is not relevant to the display of the client device, and the reduced-size version of the hypertext content may include page in a text-based hypertext markup language such as HTML. A layout conversion may be used from a first hypertext layout to a second hypertext layout of the reduced hypertext content, which may be more directly usable by a handheld wireless telephone than is the first hypertext layout.

A processor core for provides a linear extension of addressable memory space of a microprocessor with minimal additional hardware and software complexity. A N+x bit pointer register (e.g. program counter) holds an N+x bit instruction address. The N+x bit instruction address provides to an execution unit a pointer to an instruction in the memory to be processed by the execution unit. An encoder encodes the N+x bit address into an N bit encoding of the N+x bit address. The processor core can thereby address 2.sup.x times more memory locations than 2.sup.N. Two other registers each hold a portion of an data address (i.e. a pointer to a datum in memory to be operated on). An address former concatenates the portions of the address in the two registers to form the data address. Therefore, the address is formed from portions of the data address stored in multiple registers without performing any arithmetic on the portions.

摘要:
A method is disclosed for policy-based determination of a network address for a client in a network. A request for a network address is received from a client. A policy response is received that identifies a scope of network addresses for the client. A request source address value in the client request is modified, based on the policy response. The modified client request is sent to a server that can assign network addresses within the identified scope. A network address for the client is received, which has been assigned by the server within the identified scope. The network address is provided to the client. A specific embodiment modifies a “giaddr” field value in a DHCP request, before relaying the request to a DHCP server, based on a policy decision that specifies a scope to be used for the network address of the client.

A method and system are provided for transmitting information from a faster network to a data terminal via a slower network connection. The invention is adapted for use with any Internet access device or terminal, such as an Internet-compatible telephone. A client connects to the Internet via an intermediary software program, known as the Gateway (GW). In the preferred embodiment of the invention, the GW executes on a host computer of an ISP's Local Area Network (LAN). The GW thus mediates the data transfer between the Internet, such as the Web, and the client Internet terminal. The GW employs a point-to-point Internet protocol, the Gateway Interface Protocol (GWIP) to communicate with the client over the low-bandwidth link. The invention shifts the entire overhead of the Internet protocol stack to the GW, and does not involve the Internet terminal or the slow link between Internet terminal and GW. The GW makes and negotiates multiple Internet requests, in parallel, and multiplexes the resulting data streams, allowing documents to be loaded in parallel with their associated images. The GW may also be used to conveniently customize or upgrade the Internet terminal. The GW performs off-line services and caches commonly used information fetched from the Internet. The invention is also readily adapted for use with Internet access devices that require different document formats.

Methods and systems for generating and executing a database process are described. One example method includes receiving a request at the virtual server according to the infrastructure protocol, the infrastructure protocol configured to perform actions on virtual server resources; determining an application associated with the request; and performing one or more actions associated with the request using a set of application resources associated with the application.

摘要:
Techniques are described for switching from a data session to a voice session, then back to the data session. A "primary" data connection is established between a user's terminal and a communications network, which provides the user terminal with a tag identifying a voice network address (typically of a service provider) to which a voice connection can be established. The user initiates a voice connection (session) with the service provider by selecting a displayed service object associated with the service tag. During the voice session, the data session is suspended. Upon completion of the voice session, the "primary" data session is resumed. In an embodiment of the invention, a "secondary" data connection can be established during the voice session using one or more physical network connections. Data communication during the secondary data connection is optionally "remotely" guided by the service provider, and may include a distinct address for resuming the primary data connection. Video connections are accommodated during the voice session.
