IntroductionToday's distributed systems have become more and more to the application of distributed multimedia systems to go on the trend. The application of multimedia is essentially a consumption of continuous data flow. Audio and video are composed of audio sample and video frame. Sometimes because of the network conditions, he can allow partial delay, delay caused by the packet loss rate at a certain rate is also acceptable. In multimedia applications, it is very concerned about the quality

Inherited methods Connectionlost, Deliverycomplete, messagearrivedmqttclientpersistence represent a persistent data store that stores outbound and inbound messages for delivery to the specified QoS 。 You can use Mqttclient.mqttclient (string, String, mqttclientpersistence) to specify the implementation of the interface, Mqttclient will use this mq
Solve Win7 play Game card, play game delay, slow speed and so on, Win7 computer card how to deal with the solution, since October 2009 Windows7 system released, there are many netizens will be their own system from XP to Windows 7, many users, In particular, gamers have such a feeling, that is, Windows 7 faster than XP slow, playing game delay high, playing game cards. Windows 7 network slow and the same computer with Windows XP speed is not slow what's going on?

in full accordance with RFC to achieve interoperability between devices and network management systems of different vendors.
At present, the proportion of the Application Network Management System in large and medium-sized enterprise networks has been greatly increased. Therefore, when selecting a network, you cannot perform topology discovery, traffic monitoring, status monitoring, and other common network management functions, it also puts forward higher requirements for remote device configu
fast search of Route tables, bus backplane and switching structure. Second, QoS problems, such as data stream and packet classification, traffic engineering, and congestion control. Third, problems related to software, such as software stability, configuration and management. It should be noted that such classification is not strict, and some problems may fall into two categories at the same time.

Record is the value of the name field in the data table, column is the field name and value field value of any field in the data table.Basi
I recently paid more attention to the functions of routers. I have read a lot of information and summarized my views on the firmware of a third-party Router Based on my previous experience.
Now most third-party router firmware, such as Tomato, DD-WRT and so on are based on OpenWRT.
The firmware architecture of these third-party routers can be divided into front-end (Frontend) and back-end (Backend). The back-end is basically OpenWRT, and the front-end generally refers to the graphic user inter
When configuring the ISIS-TE met a pile of mpls dste command, or understand the good DSTE, read a afternoon no clue, this article writes the relationship of DSCP-PHB is quite clear, let's take a look ~~
DSCP (Differentiated Services CodePoint) distinguishes service encoding points
In the IPv4 packet header, DSCP is the first six bits in the TOS domain.
DSCP is used for QoS in DiffServ-based networks. Its function is to select PHB (Per-Hop Behavior), a
the optical switching structure is introduced. In addition, the fast search technology of Route tables, QoS Assurance, and MPLS network optimization are also being paid more and more attention to the introduction of optical switching in routers.
ASIC Technology
Because manufacturers need to reduce costs, ASIC technology has been widely used in routers. In a vro, to greatly increase the speed, the first thing you don't think of is ASIC. ASIC can be us
the X.25 group communication technology. Due to the development of transmission technology, the error rate of data transmission is greatly reduced, and the error recovery mechanism of group communication is too cumbersome. Frame Relay simplifies the three-layer protocol of group communication into two layers, that is to say, the second layer of OSI transfers data in a simplified way. Only the functions of the core layer of the physical layer and the link layer are completed, and the network doe

Brief introduction
With the rapid development of small and medium-sized enterprises, scalability, low initial investment, simple deployment, reduce footprint, pay by use, security, etc. become hot issues, these can be solved through the cloud model. In all cloud components, the multi-tenant model helps to share software and hardware layers. In layman's terms, a tenant uses all the assets of other people and pays for the use. Similarly, multi-tenant in cloud terminology means that multiple clien
