Description
Technical Field
The invention relates to the field of IPv6, in particular to a method and a system for realizing network service quality guarantee based on an IPv6 flow label.
Background
CPE (Customer Premise Equipment) plays an important role in the network, provides functions of network access, data transmission, security protection, etc. at the user side, and is an indispensable component of the normal operation of the network. The CPE is generally deployed at an edge of a network, and provides access to multiple protocols (such as cable, WLAN, 4G/5G, VPN, etc.) for users and terminals in different roles, and provides QoS guarantee for different Service accesses (Quality of Service).
The QoS allocates bandwidth for various services under limited bandwidth resources, and provides end-to-end quality of service guarantee for the services. For example, voice, video, and important data applications may be preferentially served in a network device by configuring QoS. The QoS guarantee strategy mainly comprises the functions of message marking, flow shaping, interface speed limiting, congestion management and the like.
The service models of QoS mainly include IntServ model and DiffServ model. The IntServ model describes its own flow parameters to the network through RSVP (Resource Reservation Protocol) signaling Protocol, and applies for specific QoS services. The network reserves resources to commit to fulfill the request according to the traffic parameters. After receiving the confirmation message and determining that the network has reserved the resources for the message of the application program, the user starts to send the message. The message sent by the user should be controlled within the range described by the flow parameter. The network node needs to maintain a state for each flow and perform corresponding QoS actions based on this state to satisfy the commitment to the user. The DiffServ model divides the flow in the network into a plurality of classes, each class enjoys different processing, especially different classes enjoy different levels of processing when the network is congested, so as to obtain different packet loss rates, time delays and time delay jitter. The services of the same type can be aggregated and uniformly transmitted in the network, so that the same QoS indexes such as time delay, jitter, packet loss rate and the like are ensured.
With the wide deployment and application of IPv6, it becomes more and more important to provide refined quality of service guarantees for services in IPv6 networks. The traditional QoS configuration needs to label traffic according to five-tuple (source IP, destination IP, source port, destination port and protocol) based on ACL (Access Control Lists), and because IPv6 addresses are huge in number and have the characteristics of random addresses, the traditional five-tuple configuration mode causes problems of difficult traffic identification, large configuration and maintenance workload, complex change and adjustment, and the like, and is difficult to implement landing. Therefore, a method for guaranteeing network service quality based on IPv6 flow label is needed.
