A hierarchical communication system, arranged in a spanning tree configuration, is described in which wired and wireless communication networks exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. Copies of data, program code and processing resources are migrated from their source toward requesting destinations based on request frequency, communication link costs and available local storage and / or processing resources. Each appropriately configured network device acts as an active participant in network migration. In addition, portable two-dimensional (2-D) code reading terminals are configured to wirelessly communicate compressed 2-D images toward stationary access servers that identify the code image through decoding and through comparison with a database of images that have previously been decoded and stored.

In embodiments of the present disclosure improved capabilities are described for increasing the bandwidth in a wireless communication network, where centralized optimization servers with publish-subscribe broker services are utilized in conjunction with a queuing service application that provides packet service continuity when a mobile device moves between different access control nodes of the wireless communication network, and wherein the queuing service application is connected to a publish / subscribe broker network to receive service packets matching the service packets directed to the mobile device, wherein the service application makes the matching service packets available to the mobile device to replace service packets that the mobile device did not receive during a time in which the mobile device is in transition between being connected to any of the access control nodes.

The invention provides a method and device for dynamically migrating VLAN (virtual local area network) configuration. The method comprises the following steps of: storing virtual machine ID and corresponding VLAN configuration information in a network management system in advance; transmitting the VLAN configuration of a virtual machine to an upstream physical switch corresponding to a migrated physical server of the virtual machine when the network management system senses out a network migration event of the virtual machine, wherein the migrated physical server transmits an RARP (reverse address resolution protocol) message so as to update ARP tables of all the upstream physical switches after the migration of the virtual machine is finished; and if the migration event is finished before the network management system finishes transmitting the VLAN configuration, the network management system ages the ARP table on a physical switch by an SNMP (simple network management protocol) or command line so as to update the ARP tables of all the upstream physical switches of the migrated physical server. According to the invention, the VLAN configuration of the virtual machine can be migrated dynamically along with the migration of the virtual machine.

Migration of a circuit-based-switch to a packet-based-soft-switch in a SS7 telecommunications network is accomplished with no disruption to subscriber service and retains and reuses the assigned signaling point code (SPC) of the existing circuit-based-switch. The system and method inserts a new soft-switch between an SS7 signaling transfer point (STP) and the existing circuit-based-switch in a way where traffic is split incrementally off the circuit-based-switch to the soft-switch so that no administrative changes are required at either the STP or the existing circuit-based-switch. The soft-switch is gradually cutover to act as a proxy STP and tandem switch for the existing circuit-based-switch and routes all calls to and from the network on behalf of the existing switch. The system makes use of multiple internal networks of the soft-switch to accomplish the controlled routing of bi-directional traffic. The circuit-based-switch can eventually be removed from service after subscribers are migrated to the new soft-switch.

The invention discloses a video content management method based on semantic hidden indexing, which ensures that a semantic space table (SST) and video data coexist all the time in the network migration and transmission process by defining the SST and performing integrated semantic indexing on the SST and the video data by an information hiding method. For a video application system (such as an intelligent play and download agent system, a video classification management system, a network management and control system and the like), the SST of the video data is extracted to be subjected to comparative calculation with a semantic request table (SRT) at a destination end, so that the calculation result can help the system to decide a specific processing mode of the video data. The semantic information of the hidden indexing is hard to erase or falsify, so that the semantic information loss of the video data in the secondary transmission process is prevented; and the content video data can be effectively unified and correlated, so that the redundant transmission of data is reduced, and the utilization efficiency of the network is greatly improved. Meanwhile, the video search engine and the other video application systems can be helped to better perform the selection, rejection, abandonment and other operations on the video data, so that the video data in the network space can be transmitted orderly, and the video can be found more efficiently and quickly.
