Problems solved by technology

[0037] - over-reservation, usually employed in order to compensate for the fact that users overestimate their traffic, resulting in a lack of any real guarantee,
[0038] - There is a problem with charging: when over-reserving, the charging based on (business agreement) business parameters is not directly related to the cost of the call, but the cost of the call depends on the actual traffic volume sent; when strictly guaranteed, it is not related to the reserved Charges related to reserved resources (bandwidth, memory) risk being banned
[0042] - the management business unit by type and by user is still complex (SLA management, policy server, business parameter signaling, etc.),
[0043] - low-priority types of traffic face the same disadvantages as traffic in a best-effort architecture (performance crashes when congested, no protection against malicious users),
[0044] - There is a problem with charging for different types of services: price differences are necessary but may not be understood by users if there is no significant difference in quality,
[0056] - consideration of quality of service and traffic parameters depending on the flow leads to complex implementations, which may cause deployment problems,

Embodiment Construction

[0093] figure 2 The first embodiment is shown.

[0094] In the figure, reference numeral 24 denotes a routing module or a routing device that performs admission control for a data packet 20 entering the flow.

[0095] The definition of flow is, for example, in the paper "IP traffic and QoS control: the need for a flow-aware architecture" by Bonald et al. The definition in the architecture of flow-aware disclosed in World Telecom.Conference, Paris 2002).

[0096] The data packet 20 given to the module is, for example, determined by a conventional routing function that may include load distribution obtained by applying a hash function to a subset of the fields of the flow identifier. One form of adaptive routing is obtained by including in this subset the header fields (transport protocol port number, IPv6 flow label) that will be filled freely by the user.

[0097] The module 24 consults the list 30 of protected flows and keeps it up to date, where these protected flows are actually ...

Abstract

An apparatus for processing a packet (20) of a flow on network includes a scheduling means (28) for scheduling packets in a queue according to fair queuing using priority algorithm.

Description

Technical field [0001] The invention relates to the architecture of a data packet switching network and the management of service quality in the architecture. Background technique [0002] The Internet is a multi-service tool suitable for supporting a wide range of services and applications. There are two main types of services (traffic) on the Internet: real-time (mobile) services usually generated by audio and video applications, and data (flexible) services corresponding to the delivery of digital documents. The quality of service requirements of real-time services correspond to the need to protect the signal: when the signal propagates through the network, the bit rate changes that represent the characteristics of the signal generated by the source must be protected. The quality of data services is measured by the time of document delivery. At this time, or equivalently the average bit rate achieved during the conversion, will depend on the entire communication channel from...
