Background technology
For network, the network bandwidth is the key factor determining network transfer speeds, with user to data transfer speed
The raising that degree requires, the requirement to the network bandwidth also improves therewith.Restriction at the aspect such as network construction cost and technological limit
Under, how to realize higher network transfer speeds under identical bandwidth becomes the emphasis in the research of present Ge great operator.Cause
This control of network flow quantity and network traffic analysis play more and more important effect.With bt, a sudden peal of thunder as representative on network today
P2p class download application program occupy bandwidth resources in a large number, result in network congestion and service Quality Down background under.
In order to ensure that user is capable of the use network bandwidth of equality, need to take necessary technological means expend bandwidth a large amount of to bt etc.
P2p application carries out a certain degree of monitoring and regulates and controls.Under background as above, improve service quality to reach, my company carries
Go out to further investigate the requirement of control of network flow quantity and network traffic analysis.I is to participate in my company with regard to control of network flow quantity
And on the basis of the actual items of analysis, further investigate application traffic control equipment.It is excessively used Internet resources for user, lead
The bigger pressure of broadening band network faces.Operator must take steps to meet user's request, thus not only limiting customer churn,
Consumer's Experience can also be improved, start new extra earning source.
Distributed network be by be distributed in different location and have multiple terminals Node station interconnection formed, distributed
In network, client and service end need to execute the program of the network communication part of distributed network, and then just enable client
End is communicated between service end, and that is, transmission communication data is it is seen that the program of network communication part is client and service end
The basis being communicated.
Due to it department of enterprise to the attention degree of bandwidth not enough, the application with various new networks and network
The development of multimedia technology, network bandwidth problem in short supply is more and more obvious.The basic function of Bandwidth Broker is very simple, just
It is distribution and the monitoring carrying out bandwidth according to application and user.Due to being seven layers of network management device, so network management people
Member need not possess the distribution that higher network knowledge just directly can carry out bandwidth to application and user, and this reduces to a certain extent
The input of network management personnel.Although function is very simple, the various applications being that by are a lot, simply most of use
Family is not recognized well to the application of Bandwidth Management.External bandwidth management equipment is expensive, and does not support Chinese displaying
So the application of packteer and allot is concentrated mainly on telecommunications and finance, although the manufacturer such as domestic Beijing Ying Zhi Xingda exists
Education, government, the energy and medical industry are reaped to some extent, but product line ability molding 1 year, so the popularization in market application
Each manufacturer does not excessively put into, and leads to user that the application of Bandwidth Management is in the junior stage.
