The address rotation system replaces the first network address with a second network address and updates the name service to resolve a second name to the second network address. The address rotation system updates the content delivery service with the second name to allow the content delivery service to use the second name to obtain the second network address and access the origin server. |

Network architecture for parallel data stream analysis and modification
Network architectures interface with several real-time streams that control network operation. The network can analyze stream data by storing incoming raw stream data, processing the data, and controlling network operations based thereon. Specific packets, bits, flags, fields, or messages may be targeted, including HL7 ADTs. Data is queued for processing in a FIFO manner to avoid timeline mistakes. The network sets a configuration value based on the data analyzed in this time ordering, and a relational database can be updated in real-time with these values as stream data is incoming. Separate clean-up functions separately manage the database by adjusting the values as they become old. Timeline information is generated and selectively broadcast based on the operations value, potentially with additional information from the targeted data. The network selectively provides this information to users interfaces and displays as dictated by the operating value and information calculated therefrom. |
