S506a, the VNFM send request message to the VIM, carry the mark of the VNFM, the link information of the VNFM and the resource quota information in the request message.

Above-mentioned S507 may include:

After S507a, the VIM receive the request message, when the VIM does not set up the connection with the VNFM, which saves the mark of the VNFM, the link information of the VNFM and the resource quota information.

Further, VIM is during establishing the connection with VNFM, after the resource quota information is saved, when the VIM is that the VNFM distributes resource, if the stock number that the VNFM is requested to the VIM is more than resource quota indicated by the resource quota information, which can refuse to carry out resource allocation for the VNFM.

It optionally, can also be that the VNFM carries out resource allocation by following several modes in embodiments of the present invention when the stock number that VNFM is requested to VIM is more than the resource quota for the VNFM.

Below with reference to VIM1, VIM2, VNFM1 and VNFM2, following several modes are illustratively illustrated.

Mode 1:

After S10, VIM1 receive the request message of VNFM1, the resource that VNFM1 is requested to VIM1 is determined according to the request message, has been more than the resource quota for VNFM1.

Wherein, resource quota, which refers to, allows VIM1 to be total up to the maximum resource amount that VNFM1 is distributed.

S11, VIM1 send a notification message to management node, and the stock number of notice management node VNFM1 request has been more than the resource quota.

Illustratively, VIM1 can notify management node, relationship, the information of the stock number exceeded of request between the stock number and the resource quota of VNFM1 request etc..For example, needle The 40% of the total resources that resource quota to VNFM1 is VIM1, VNFM1 is at this to before VIM1 requests resource allocation, 20% resource of VIM1 has been requested to VIM1, this VNFM1 requests 30% resource of VIM1 to VIM1, then, VIM1 can notify management node, the remaining available volume of resources of VNFM1 is the 20% of the total resources of VIM1, for example, the total resources of VIM1 is 10 CPU, then the remaining available volume of resources of VNFM1 is 2 CPU.

S12, management node carry out judgement or decision according to the resource using information of preservation.

Wherein, resource using information is used to characterize the resource allocation conditions of VIM1, is recorded in the resource mapping table of management node preservation.

Illustratively, if management node is inquired by the resource using information to VIM1, determine that VNFM2 used stock number on VIM1 is less, remaining available volume of resources of the VNFM2 on VIM1 is more, then resource quota of the management node adjustable VNFM1 and VNFM2 on VIM1.

S13, management node send the updated resource quota information for being directed to VNFM1 to VIM1.

Illustratively, resource quota of the VNFM1 on VIM1 can be adjusted to 60% from the 40% of the total resources of VIM1 by management node, and the resource quota by VNFM2 on VIM1, be adjusted to 40% from the 60% of the total resources of VIM1.

S14, VIM1 distribute resource according to the updated resource quota information received, for VNFM1, and send response message to VNFM1.

It should be noted that VIM1 determines the request that can satisfy VNFM1 according to updated resource quota information, so that VIM1 can distribute resource for VNFM1.

Mode 2:

S20, VIM1 receive the request message of VNFM1, determine the resource that VNFM1 is requested to VIM1 according to the request message, have been more than the resource quota for VNFM1.

S21, VIM1 send a notification message to management node, notify management node, the stock number of VNFM1 request has been more than the resource quota.
