| 20100131599 | Methods, Systems, and Computer Program Products For Instant Messaging - Systems, methods and computer program products for monitoring the receipt of instant messages between two or more participants in a messaging environment are described herein. An embodiment of the invention operates by receiving a message from a sender. The message is displayed in a chat client of a recipient. Such message is displayed in an encrypted form to prevent human intelligible display of the message. An indication of selection of the message by the recipient is received. Thereafter, the message is displayed in the chat client in an unencrypted form, and an acknowledgement is sent to the sender. The sender updates a message status identifier by filling the message status identifier with a color or updating an icon or any other visual cue or identifier, uniquely identifying the message recipient, to thereby note the selection of the message by the recipient. In this way, the recipient of a message must select the message in order to view the message in its unencrypted form. When the recipient selects the message with a mouse pointer or any other interaction method, an acknowledgement is sent to the sender, indicating that the message has been viewed by the recipient. This prevents an assumption by the sender that the message has been viewed by the recipient until it is actually viewed in its unencrypted form. | 05-27-2010 |

For example, an embodiment of the method may include allocating network system resources to high-priority data with an identifier and dynamically changing a threshold level from a pre-assigned, minimum level in the allocation of network resources based on data traffic with the identifier received by a communication device in the network system. In allocating network system resources, the data with the identifier may be filtered into a separate data stream from data without the identifier. For instance, the data stream containing data with the high-priority identifier may be directed to a high-priority buffer that has a minimum allocation of network resources dedicated to the buffer to ensure unencumbered data transfer between the communication device and a destination within the network system. Further, in dynamically changing the threshold level, network resources may be allocated to data with a high-priority identifier as the high-priority data is received by the communication device. A prioritization of network resource queue space for the data with the high-priority identifier and then a prioritization of data without the high-priority identifier in the remaining queue space, if any, according to Quality of Service (QoS) requirements may be required when allocating network resources. Therefore, the method described above may be used to propagate prioritized data across a network while accommodating for QoS requirements. | 01-14-2010 |
