Embodiment Construction

[0046] The present invention is described below with reference to the accompanying drawings, which Figure 1 Generally deals with networks, network devices within them, and their configuration and operation.

[0047] In some networks, different data packets may have different QoS requirements. Data packets can be divided into different categories, each of which has corresponding QoS requirements. In some cases, network devices can be used to provide differentiated services for these packets through individual configuration of each network device on the data path. For example, network devices may be individually loaded with appropriate software or firmware supporting differentiated services, and may be configured through configuration commands from an administrator (eg, through configuration commands from an administrator device directed to individual devices for configuration). However, this separate configuration may not be ideal. According to one example of the current te...

Abstract

An apparatus comprises: a network interface for connecting to a network; the database is used for storing traffic shaping parameters of traffic shaping schemes for the data packets of various categories; the database loading circuit is used for acquiring the traffic shaping parameters from in-band communication received by the network interface in a data packet and loading the traffic shaping parameters into the database; and the one or more traffic shapers are used for accessing the traffic shaping parameters in the database and applying the traffic shaping scheme to the various types of data packets received by the network interface according to the traffic shaping parameters.

Description

technical field [0001] The invention relates to the technology of providing differentiated services in the network. Background technique [0002] The Internet Protocol (IP) is the most widely used technology in Layer 3 of the Internet Open System Interconnection (OSI) model. In Layer 4 of the OSI model, Transmission Control Protocol (Transmission Control Protocol, TCP) and User Datagram Protocol (User Datagram Protocol, UDP) are the most widely used protocols in IP networks. The design of the Internet protocols is based on the end-to-end principle. Network infrastructure is considered to be inherently unreliable on any single network element or transmission medium, and dynamic in terms of link and node availability. There is no central monitoring or performance measurement facility to track or maintain the state of the network. To reduce network complexity, smart devices in the network can be located in end nodes. Contents of the invention [0003] According to an aspe...
