Enable service quality middleware for MPEG Video Streams
(1) Introduction
Online Video Stream services have become very popular on the Internet in recent years. Video Streams are a type of concurrent processing. They send video images from the server to the client over the network and are played by the client video player.
The online video stream service system is an online, strict real-time multi-user system. It cannot be controlled in open networks (such as the Internet), and its performan
At present, FTTH as a new hotspot technology in the field of broadband access has attracted the attention of operators, among which Epon technology has many advantages such as high maturity and low cost, and becomes the preferred scheme for FTTH. Epon is an important part of IEEE 802.3ah workgroup (ie EFM, First mile Ethernet), the main idea is to apply Ethernet technology on the PON network structure, which makes epon can directly inherit the low cost of widely used Ethernet technology and many
the focus of telecom operators, at present, there are a wide range of metropolitan area Network technology, which includes metropolitan area network based on SDH structure, metropolitan area network based on Ethernet structure, metropolitan area network based on ATM structure and metropolitan area network based on DWDM structure. In fact, SDH, ATM, Ethernet, WDM and other technologies are constantly absorbing the strengths of other technologies, each other, that is, to achieve rapid transmissio
As an inbound or outbound QoS site, edge switches play a very important role, especially in small and medium enterprises, if the edge devices of the network integrate QoS, rate limit, ACL, PBR, and sFlow into the hardware chip, the Intelligence will not affect the line rate forwarding performance of the basic layer 2 and Layer 3, therefore, the end-to-end smart network can be carried out on a large scale, s
Ethernet switches are still commonly used. So I studied whether SPOH technology has triggered the Ethernet switch revolution. I would like to share it with you here, hoping it will be useful to you. The rapidly expanding "Network Society" poses severe challenges to Ethernet switches serving as data processing centers. First, in the face of overload data transmission, the smooth operation of network services requires end-to-end service quality assurance.
In network data transmission, the data siz

In addition to further optimizing the performance, compressing the size, and improving the reliability of the Linux technology in consumer electronic products, building a sound and elastic power management system has become an increasingly important project and requirement, it will also become an important tool for Linux to replace traditional RTOS, WinCE/mobile, and Symbian, and occupy the leading position of the open-source software (OS) of consumer electronics.

As a pioneer in Internet and IP network infrastructure, a leading company in the fields of ATM, frame relay, communication information management, and Quality of Service (QoS), Cisco is the only company capable of building an intelligent multi-service network, it gives enterprises great flexibility to adapt to the changing business and needs.Core of Cisco IGX 8400 series Enterprise Wide Area Network

4) Configure dhcp on two different logical sub-interfaces, eth1/0.1 and eth1/0.2, and apply dhcp on two vlan networks on the same physical interface to allocate two different network segments.

up, the project urgently needed a anti-loss packet, anti-Chaos enhanced UDP scheme to enhance the real-time audio and video transmission effect, after years of accumulation and improvement, we have introduced a set of RTP-based and FEC forward error correction and back-end QoS processing of a complete solution, the effect is very obvious.

Edge Switch Equipment plays a very important role in networking. How can we balance the intelligence and performance of edge Switch Equipment? If the edge switch device of the network integrates QoS, rate limit, ACL, PBR, and sFlow into the hardware chip, the Intelligence will not affect the line rate forwarding performance of the basic layer 2 and Layer 3,
Therefore, the end-to-end smart network can be carried out on a large scale, so that the entire
In addition to connecting to the same type of network, edge switches can also interconnect different types of networks, such as Ethernet and Fast Ethernet. I hope this article will help you.
With the development of the communication industry, people have higher requirements for intelligence. As a representative of smart exchange devices, edge switches are gradually increasing in market demand. If the edge devices of the network integrate QoS, rate lim
