Description
(1), technical field: the present invention relates to a kind of first Capacity Management collocation method, particularly relate to a kind of first Capacity Management collocation method based on XML.
(2), background technology: through the develop rapidly of nearly decades, the Internet becomes the important component part of national information infrastructure day by day, its range of application has penetrated into human lives's every field, becomes the important carrying platform that the mankind carry out social activities and information interaction.Support the design that its successful main cause is internet architecture: the core in the Internet adopts protocol hierarchy isolation complexity and guarantees interoperability (interoperability), its thin waist structure makes network layer " statically " to support the diversity of other layer to expand.This architecture made the Internet can complete well basic communication task and obtained develop rapidly within nearly decades.
Yet, along with various forms of end systems accessing Internet (as sensor node, mobile phone etc.) constantly, the continuing to bring out of various communications applications (as P2P, VoIP, game on line, video conference, social media etc.), the current architecture in the Internet is faced with the severe network problem that " ossifys ", and the ability of network inherence and structure are difficult to adapt to new business demand.From the angle analysis of service, network ossify problem mainly contain following some: 1) service extension insularity: network is difficult to add corresponding function and service to network core as required.2) service instantiation ossifys: application layer services is difficult to access as required or call resource and the service of network core.3) service granularity ossifys: the Internet only can provide the service of the coarsenesses such as IP, UDP, TCP to upper-layer service application, can not be according to the variation of application demand " dynamically " for setting up fine-grained service stack.4) service level is divided and is ossify: current internet hierarchical structure is strict, and layer is blocked alternately with interlayer, is difficult to realize cross-layer mutual.
In order fundamentally to break through the ability bottleneck of Traditional IP carrying, solve the problems such as service extension is poor, service instantiation is difficult, serve coarse size, service level division is stiff.Application for a patent for invention (application number: CN201310307096A) proposed to take the function automatic combination method that " reconstruct " is core.Logical level division methods based on " business-unit service-first ability ", by basic network Function Decomposition, be fine-grained functional template, its way of realization is called first ability, the differentiation of network based service request, the combination chain of dynamic construction different size, realizes the support to diversified business.
