Deferred invocation of communication services
In one embodiment, a network device determines one or more conditions for invoking one or more real applications to the network device for a session. This determination may be made at the initiation of the session, such as when a SIP INVITE message is received. The one or more conditions allow real applications to be invoked when a future event satisfies the condition. When it is determined that a condition is satisfied, a real application associated with the condition is then invoked. Accordingly, conditions may be set for real applications that may be tested against future events that have not yet occurred. This allows deferred invocation of real applications. Accordingly, if real applications are not needed for a session, then they are not invoked. But, when a real application is needed, it can be invoked. |

Grid proxy architecture for network resources
A Grid Proxy Architecture for Network Resources (GPAN) is proposed to allow Grid applications to access resources shared in communication network domains. GPAN bridges Grid services serving user applications and network services controlling network devices through its proxy functions such as resource data and management proxies. Working with Grid resource index and broker services, GPAN employs distributed network service peers (NSP) in network domains to discover, negotiate and allocate network resources such as bandwidth for Grid applications. An elected master NSP is the unique Grid node that runs GPAN and represents the whole network to share network resources to Grids without Grid involvement of network devices. GPAN provides the Grid Proxy service (GPS) to interface with Grid services and applications, and the Grid Delegation service (GDS) to interface with network services to utilize network resources. Resource-based XML messaging is employed for the GPAN proxy communication. |

Multi-master text synchronization using deltas
A server enforces a policy for selecting what received change to process. The non-selected changes are not processed by the server. Instead, after the selected change is processed and is incorporated into the current version of the text, the server sends an update to each of the clients indicating the change made to the current version of text. A client performs a conflict resolution procedure when its change was not processed by the server. The conflict resolution procedure detects the differences between the updated text version and its text change that was not accepted by the server and uses the differences to deduce the intent of the user and come up with a merged version of the text which preserves the intent and avoids data loss. The updated version is then sent back to the server to update the current version of the text. |

Intelligent saturation of video data
The intelligent saturation controller calculates the exact maximum saturation any valid YCbCr pixel can undergo before it becomes invalid in ROB space. The controller models the saturation operation in RGB color space and calculates the maximum saturation level at which the RGB values falls outside the valid range.

The controller finds the maximum saturation for each input pixel and checks whether it is less than the input saturation factor. If so, then this calculated maximum saturation value is applied. If not, the input saturation factor is applied. Accordingly, the output RGB pixels are valid and no clamping is necessary if no other video processing is done in YCbCr space. Increasing the saturation of the video signal results in a more vivid and more colorful picture. |
