The present invention provides a system and method to permit the network management system to indirectly manage layer one telecommunication resources dedicated to a carrier virtual network from a dedicating telecommunication network. In each telecommunication network a business layer allows that telecommunication network's management system and the layer one resources in that network to exchange network information and network instructions. One or more communication layers transmits messages having a predetermined format, such as XML or ASCII text, between the telecommunication layer to a format useable by the network management system associated with the interpretation layer for use as network information or network instructions.

The invention provides a node protection method, a packet filtering device and a virtual network system. The node protection method comprises the following steps: capturing a message transmitted to a first node by the packet filtering device of a first node, and carrying out security verification on the message according to a pre-stored authorized address list and the source address of the message; if the message passes the security verification is detected to be a connection request message, adding a second node address carried by the connection request message to the authorized address list so that a message from the second node address can pass the security verification, wherein the first node is a node requested by the connection request, and the second node is a request initiating node for initiating the connection request. The node protection method, the packet filtering device and the virtual network system are capable of providing effective and reliable protection for the nodes while guaranteeing the network performance.

The invention discloses a method, a device and a system for number information synchronization, which relate to the technical field of communication and solve the technical problems in the prior art that users must input short number information into a phone book manually. The method includes: obtaining user identification which is sent by the users and is synchronous with request short number information; determining short number information corresponding to a virtual network where the users belong according to the user identification; and synchronizing the determined short number information to the phone book relative to the user identification in corresponding mode. An embodiment of the method, the device and the system is mainly used for the phone book.

The invention provides a session management method, an entity, network equipment and a storage medium. The method comprises the following steps: sending a group-level session management request to a control plane entity based on a service demand, wherein the group-level session management request carries group information, and the group information is used for representing a virtual network group needing to be subjected to group-level session management; receiving a response message returned by the control plane entity in response to the group-level session management request; and performing corresponding session service management on the virtual network group according to the content carried in the response message.

A virtual network control apparatus configured to perform assignment of physical resources under management for a virtual network embedding request, including: a physical network resource management agent configured to manage use state of resources on a physical network at each future time; and a virtual network control agent, the virtual network control agent including: demand prediction means configured to perform prediction of future demand for a virtual network; and use resource determination means configured to calculate physical resources to be used at each future time by the virtual network based on a prediction result of the demand obtained by the demand prediction means and information of future use state of resources on the physical network obtained from the physical network resource management agent, and to notify the physical network resource management agent of information of physical resources of the calculation result.

The invention discloses a virtual network adopting a roaming access way based on mobile communication. The virtual network comprises mobile phone networks (1) and an authentication and accounting system (2) for authenticating the identities of user mobile phones (3), wherein the mobile phones (3) are provided with SIM cards belonging to the virtual network identity; the mobile phone networks (1) provide roaming access for mobile phones (3) of the virtual network, and perform authentication on accessed mobile phones (3) through the authentication and accounting system (2); and the authentication and accounting system (2) records the call volumes and data usage of the mobile phones (3) in the mobile phone network (1) through the mobile phone network (1), and charge the users according to thecall volumes and data usage. Through adoption of the virtual network, the service coverage can be expanded through access to different networks in a roaming way; the cost on repeated laying of base stations is lowered greatly through sharing of the base stations; and up to two thirds of base stations can be saved.

The invention relates to a dynamic event-based network semantic model rebuilding system and method. The dynamic event-based network semantic model rebuilding system comprises a system data receiving module used for receiving system data, an event generating module used for generating a system event based on the system data, a relation association module used for associating a network semantic relation of a network semantic information model with the system event, and a network semantic relation reconstitution module used for reconstructing the network semantic relation by utilizing a domain data analysis algorithm through analyzing the network semantic information model associated with the system event to form a new dynamic network semantic model. The new dynamic semantic model is overlapped with an existing network information model, and is changed when the system event is changed, so that context information of a virtual network is more flexible for upper application of data analysis, and data analysis needs under different application scenes can be met.

The invention provides a high-density container network deployment method and system, relates to the technical field of communication networks, can be applied to the financial field and other fields, and comprises the steps of a master node of K8s obtaining an IP address from a network pool and creating an IP address declaration; sending a first container creation request containing the IP address declaration; scheduling a new container to a working node of K8s according to the first container creation request; generating new container configuration information of the corresponding working node according to the first container creation request and the scheduling result; the working node obtaining the IP address, the VLAN and the gateway of the new container according to the new container configuration information of the working node; creating a virtual network port on a virtual switch of the working node, and generating an mac address; and establishing an association relationship among the IP address, the VLAN, the gateway and the mac address of the new container. According to the invention, the container deployment upper limit and virtualization multiplying power of the single server can be improved.
