The application discloses a kind of edge virtual network function system framework and network architecture, its system framework includes: portal control center, service ability empowerment and dispatching middle station and multiple POP clusters;Wherein, portal control center is used to face user, operation and maintenance, operation and service provider provide unified entrance, include portal management, operation and maintenance alarm system, operation work order system, order and delivery management system and unified identity authentication system;Service ability empowerment and dispatching middle station are responsible for connection control module, API gateway, tenant management, service guarantee, identity authentication, multiple cluster resource scheduling strategy issue and third party interface unification;POP cluster is used to be responsible for service chain arrangement and the operation of NFV network function pool, in combination with monitoring and operation, resource scheduling and high-performance forwarding surface complete tenant business load.The application realizes controllable flow arrangement under the multi-tenant scenario, resource elastic allocation and performance guarantee, improves the flexibility, scalability and user experience of NaaS platform.

The application relates to the technical field of network communication, and discloses a deterministic forwarding processing method and device based on an IPv4 network, which comprises the following steps: a controller issues service flow information to a first node; the first node matches corresponding service flow according to a service flow characteristic policy in the service flow information, inserts a corresponding outer IPv4 header, a segment routing header field SRH and a segment routing operation field SR-OPT in front of an original IPv4 header of the service flow, and encapsulates the service flow to obtain a message; the first node performs deterministic forwarding processing on the message according to a deterministic processing method parameter table DNET and an outer IPv4 header destination address in the message; and if no congestion and no link failure occur in a transmission path from a sending end to a receiving end, it is judged whether nodes on the transmission path from the sending end to the receiving end, except the first node, support deterministic forwarding. The application can realize the functions of deterministic low latency, low jitter and high reliability service guarantee.

The application provides a network service guarantee method, device and equipment, the method comprises the following steps: predicting target users needing network service guarantee through a scoring model based on historical service data and subscription package levels of users; collecting network index historical data of the target users, and obtaining a guarantee priority evaluation value by processing and weighting different categories of network indexes through corresponding statistical algorithms according to the network index historical data; determining a service guarantee order according to the guarantee priority evaluation value of the target users; establishing an elastic GBR resource pool, which is configured to share resources when idle and exclusively provide the GBR resources to the target users according to the service guarantee order when congested.

The application discloses a network traffic monitoring system and method based on SDN, and relates to the technical field of software-defined network.The system comprises: an edge perception layer, which is used for identifying the characteristics of network data packets in real time by using a traffic characteristic identification engine, generating a traffic prediction result, dividing the traffic into different types according to the traffic prediction result, and dynamically allocating preprocessing computing power according to the traffic type; an SDN control layer, which is used for constructing a double-agent architecture by using a global controller and a plurality of local controllers, the double-agent architecture being used for acquiring traffic processing requirements of the edge perception layer and service requirements of a service guarantee layer, outputting a global resource allocation strategy, and delivering the global resource allocation strategy to the edge perception layer; and the service guarantee layer, which is used for monitoring the running performance of different network slices by using a slice performance monitoring module and feeding back the running performance to the SDN control layer.The application can solve the problem that resource waste and insufficient service performance coexist in the prior art.
