This article describes the design and implementation of QoS support in Linux 2.4.x kernel, and detailed analysis of the default packet scheduling mechanism pfifo.
In traditional TCP/IP routers, all IP data packets are transmitted using a FIFO (first-in-first-out) mechanism. In the early days when the network data volume and key business data volume were not large, the router simply discards the data to deal with congestion. However, with the developm
(I searched for a circle and did not find the Chinese Gargoyle Router and Its QoS Operation Experience, tutorials or other materials. So I went to the Gargoyle Wiki and took some notes, some of the following content is my understanding of the Gargoyle Royle QoS, and some limitations may only be reflected in the Gargoyle Router .)
QoS is short for Quality of Servi
In traditional IP networks, each forwarding node treats all packets equally, and uses the first-in-first-out policy to send the packets to the destination, it cannot guarantee the reliability, transmission latency, and other performance of message transmission.
In the broadband network environment supported by multiple businesses, different types of businesses have different network performance requirements. customer-centric, meeting the service quality at different levels is a major feature o
An article on QoS in a variety of Windows XP optimization articles has a long history, and it has been around since Windows XP was first released, and it's still appearing in optimized articles that appear frequently in various Windows XP.
So what exactly is this technique?
Let's take a look at one version of this optimization technique first.

Video applications are highly time-sensitive and require high real-time performance and service quality management (QoS). However, many applications on the Internet are mostly "best effort data ". The most effort data is characterized by a burstable nature, which seriously affects applications with extremely high time sensitivity. This increases the latency of these applications and causes jitter at the same time, resulting in serious consequences. IP
QoS Assurance Measures for VoIP services are currently the topic most discussed in the industry. IETFInternet Engineering Task Force) several technical solutions to support QoS are recommended, mainly including: Integrated Service Int-serv) /Resource Reservation Protocol (RSVP), Differentiated Services (DiffServ), Multi-Protocol Label Switching (MPLS), and business Traffic Engineering (Traffic Engineering.

Quality of Service (QoS)1: on the Internet or other networks, Quality of Service (QoS) indicates that the transmission rate, error rate, and other characteristics of the network can be measured and improved, and to some extent, advance assurance.

When QoS is implemented, traffic-based features are first classified and different levels are marked on the edge of the network; NBAR: an advanced classification method that supports high-level application information classification; Layer

P2P-based applications and some viruses are the main factors affecting the quality of network operation in recent years. In this regard, limiting the number of connections and bandwidth at the hardware layer is a

When www.2cto.com is used for hybrid scheduling, packets in the PQ queue are first scheduled. The highest priority queue is f

1 Introduction VoIPVoice over IP is a technology that uses an IP network for voice communication. As IP technology is a connectionless technology, the original intention of an IP network is to provide a service called "Best Effort" and "Best Effort, this is suitable for data services that only require accuracy and have no strict requirements on latency. For real-time communication services such as voice and video, their Service Quality is of Service and QoS
