Abstract:
A mechanism is provided for augmenting the mail header of a message with a list of digital signatures representing the chain of contributors to the message. The augmented header may also encode the actual contributions corresponding to each digital signature. The list is appended every time a message is forwarded. If a message has a portion with no corresponding digital signature or if one or more of the digital signatures is not trusted, the user may handle the message accordingly. Furthermore, a mail server or client may discard a message if the number of digital signatures exceeds a threshold to filter out unwanted messages, such as e-mail chain letters.
Abstract:
A method and a computer program product for promoting collaborative, consensus-driven decisions from a plurality of decision-making entities using electronic communications in a real-time forum. The inventive instant messaging application can be used for registering participants, developing forum pages, communicating queries, receiving messages and tallying responses that can enable implementation of online trading transactions. The application module and support databases are maintained by one or more central coordinators that reside as software objects on a server. Setpoint values are used for measuring the extent to which the participants' cumulative response satisfies one or more decision parameters. Arbitration and intra-group caucusing can also be initiated as a means to promote consensus and arrive at a collective decision. The collective decision can be used to initiate a specific course of action that may involve further communications with one or more remote trading networks.
Abstract:
A method and computer program for resetting the value of a coupon based on market information is provided. The program receives a request for valuation of a coupon from a retailer, accesses market demand information for a product corresponding to the coupon, determines a market demand value based on the market demand information, determines a coupon value based on the market demand value, and provides the coupon value to the retailer.
Abstract:
A method, program and system for enabling alternate input commands by means of a stylus associated with a personal digital assistant (PDA) are provided. The method comprises applying pressure to a pressure sensor on the stylus, which invokes an application on the PDA that interprets stylus input as equivalent to a right mouse click on a computer. In response to the stylus being touched to an object displayed by the PDA, the application opens a menu associated with that object, wherein the menu allows a user to initiate specified object functions and to change specified properties of the object. Invoking the application on the PDA is accomplished via a Bluetooth™ signal between the stylus and PDA.
Abstract:
A method and system for self-healing of routers within a distributed computer network. In response to a detected communication error at a local router over a primary communication path to a distant router, an alternate path is established. Thereafter, a diagnostic process is initiated in the distant router via the alternate path. Communication settings are then reconfigured in the distant router and communication via the primary communication path is tested. If communication is restored, the new communication settings are made permanent. If communications via the primary path are not restored, alternate communication settings are attempted in the local router and communication is tested again. If communication is re-established via the primary path, the new communication settings are made permanent.

Abstract:
DHCP lease negotiation is performed in advance of a specified time when the IP address is needed. The client sends a DHCP discover message with an advance lease option indicating a future time when an IP address is needed. The DHCP server reserves an IP address available at the requested time for the requesting client and sends a DHCP acknowledgment of the reservation. Thereafter, the client sends a DHCP discover message requesting the reserved IP address, and the DHCP server assigns it to the client at the scheduled time.
Abstract:
A memory registration abstraction layer includes decision logic for dynamic, efficient determination of memory copy versus registration. The exemplary embodiments apply to direct memory access environments. The memory registration abstraction layer also includes tracking logic for monitoring the usage history for certain ranges of memory registration requests. The registration logic chooses to copy memory or map memory based on training and observation of application behavior, taking the more efficient performance path without requiring changes to the application.
Abstract:
A method, system, and computer program product for optimizing a message size for communication in a communication network are disclosed. The method comprises identifying a connection to a target, sending to a path maximum transmission unit value server (which is not the target) a request for a path maximum transmission unit value for the connection to the target, and, in response to receiving the path maximum transmission unit value for the connection to the target from the server, optimizing a communication by sending to the target a packet having a size in accordance with the value.
Abstract:
Data communications through a split connection proxy in a data communications protocol, including receiving in a proxy from a client, asynchronously with respect to any other messages between the client and the proxy, one or more client messages including client message data items including a connection request for a connection between the client and the proxy, destination connection data identifying a destination server, and a message from the client to the destination server; and sending from the proxy to the server, asynchronously with respect to any messages between the client and the proxy and asynchronously with respect to any other messages between the proxy and the server, one or more proxy messages including proxy message data items including a connection request for a connection between the proxy and the destination server and the message from the client to the destination server.
