Abstract: Computer architecture and method splice a new TCP connection. A proxy group for the new TCP connection is determined and, at one of the proxies, the new TCP connection is accepted. At the one proxy, a client request is received from a client of the new TCP connection and an appropriate backend server to handle the client request is determined. At the one proxy, the client request is spliced and sent to the appropriate backend server. Splicing state information of the new TCP connection is sent from the one proxy to other proxies of the proxy group. Each subsequent TCP segment of the new TCP connection is spliced and sent to the appropriate backend server at any one proxy of the proxy group.

Abstract: Systems and method provide witness based tracking. An encounter with a first mobile sensor module and a second mobile sensor module is determined. At least one witness event of the encounter is recorded, the witness event comprising a mobile ID of at least one of the first and second mobile sensor modules and a time of the encounter. Stored witness events are exchanged between the first and second mobile sensor modules. Stored witness events are transmitted to an access point when the access point is within communication range of at least one of the first and second mobile sensor modules. Received witness events are sent from the access point to a data processing center and stored within a database. The witness events stored within the database are processed to determine a last encounter of one or both of the first and second mobile sensor modules.
