Description
(1), technical field：It is more particularly to a kind of to be based on XML the present invention relates to a kind of first Capacity Management collocation method
First Capacity Management collocation method.
(2), background technology:By developing rapidly for recent decades, internet is increasingly becoming national information infrastructure
Important component, its range of application has penetrated into the every field of human lives, and social activities and letter are carried out as the mankind
Cease the important carrying platform of interaction.Support the design that its successful main cause is internet architecture：In the core of internet
The heart is isolated complexity and ensures interoperability (interoperability) using protocol hierarchy, and its thin waist structure causes Internet
Can " statically " support that the diversity of other layers extends.The architecture enables that internet completes basic leading to well
Trust business and achieved in recent decades and develop rapidly.
However, as various forms of end systems constantly access internet (such as sensor node, mobile phone), respectively
That plants communications applications continues to bring out (such as P2P, VoIP, game on line, video conference, social media), internet current arrangements
Structure is faced with network " rigid " problem of sternness, in network ability and structure be difficult in adapt to new business demand.From clothes
The angle analysis of business, network ossify problem mainly have it is following some：1) service extension insularity：Network is difficult to as needed to net
Network core adds corresponding function and service.2) service instantiation ossifys：Application layer services are difficult to access as needed or call
The resource of network core and service.3) service granularity ossifys：Internet is only capable of providing IP, UDP, TCP etc. to upper-layer service application
The service of coarseness, it is impossible to change " dynamic " according to application demand to set up fine-grained service stack.4) service level is drawn
Divide and ossify：Current internet hierarchical structure is strict, and layer is interacted with interlayer and is blocked, it is difficult to realize that cross-layer is interacted.
In order to fundamentally break through the ability bottleneck of Traditional IP carrying, solution service extension is poor, service instantiation is difficult,
The problems such as service coarse size, service level divide stiff.Application for a patent for invention (application number：CN201310307096A) propose
It is the function automatic combination method of core with " reconstruct ".Based on the logical level division methods of " business-meta service-unit's ability ",
It is fine-grained functional template by basic network Function Decomposition, its way of realization is referred to as first ability, and network is according to service request
Differentiation, the combination chain of dynamic construction different size realizes the support to diversified business.
