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
default) the software can automatically open the external port at the gateway without any configuration, and the speed will be improved to a certain extent.
Third, turn off the SSID
The SSID (Service Set Identifier) is typically the local area network name that is broadcast by the AP or wireless router, and is designed to allow computers that have only the wireless router set to a value of the same SSID to communicate with each other. For BT downloads, we recommend that you turn off the SSI
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.

achieve the highest efficiency and reduce costs. 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

2) on the two lan ports eth1/1 and eth1/2 of Huawei router 1821, two VLANs (vlan2 and vlan3) are divided ).
3) Configure nat and apply it to two different logical sub-interfaces, eth1/0.1 and eth1/0.2.
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.

For packet loss, we use the improved Vander
For an enterprise, the management of the internal network is very important, so as to ensure the normal operation of enterprises, because modern methods have become increasingly inseparable from the network.
One but the network problem, then the loss will be huge, want to manage a network, then the QoS function of routers is essential, this article is about Huawei Router ip-based network management.

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
During the PTN Network Period, the integration of transmission-side and wireless-side maintenance must be put on the agenda. First, the core technology of the PTN network is Packet Exchange. The "Elastic Pipeline" feature gives the technology the advantages of statistical reuse, greatly improving the resource utilization of the network, it also brings about problems such as how to implement emergency communication protection without affecting the transmission network structure by analyzing netwo
