Among them, DiffServ is considered to be the most promising technology for solving QoS problems in IP networks because of its good expansion performance.
  • differentiated services The basic idea of differentiated services is to classify the user's data flow according to the quality of service requirements. Any user's data flow can enter the network freely, but when the network is congested, higher-level data flows are queued and occupy more resources than levels. Lower data streams have higher priority. Differentiated services only promise relative service quality, and do not promise specific service quality indicators to any user. Under the differentiated services mechanism, users and networks Network management departments need to agree on a service level contract (SLA) in advance. According to the SLA : the user's data flow is given a specific priority level. When the data flow passes through the network, the router will adopt a corresponding method (called hop-by-hop behavior. " PHB ”) to process packets within the stream. Differentiated services contain only a limited number of business levels, and the amount of status information is small, so it is simple to implement and has good scalability.
