Problems solved by technology

[0003] The development of SD-ICN is still in its infancy. The existing research is only a simple combination of SDN and ICN. SD-ICN’s scalability problem will become more prominent due to the operation mechanism of ICN itself and the introduction of network-level caching function.

Embodiment 1

[0021] figure 1 It is a flowchart of a resource-aware adaptation method with good scalability provided by Embodiment 1 of the present invention. Such as figure 1 As shown, it mainly includes the following steps:

[0022] Step 11. Each regional controller obtains the service resources that the corresponding service resource entity can provide according to the registration or updated registration information of its subordinate service resource entities; Update its status information, topology information, and performance information to realize dynamic perception of controller resources.

[0023] Before this step, it includes: the service resource entity and the network resource entity register with the local area controller; the service resource entity includes: a server; and the network resource entity includes: a terminal, a server and a switch.

[0024] Wherein, the registration of the service resource entity with the local area controller includes: sending its own service...

Embodiment 2

[0040] In order to facilitate understanding of the present invention, below in conjunction with figure 2 The present invention is further introduced.

[0041] The structure of the embodiment of the present invention is as figure 2 As shown, for the sake of simplification, the controller in the figure is only divided into two layers, that is, the area controller at the bottom layer and the root controller at the top layer. The regional controllers at the bottom only maintain relevant information within the region, while the top-level controllers maintain global relevant information for the entire network. In the embodiment of the present invention, the deployment and hierarchical division of the controllers are determined by the network operators, and the regional controllers are responsible for managing the network devices in their regions, collecting network resource information and service resource information, summarizing the summary and submitting the summary to its sup...

Embodiment 3

[0079] The embodiment of the present invention combines the attached Figure 4-5 Introduce the process of resource collection perception, dynamic adaptation and path generation. in, Figure 4 Describes the resource adaptation path and generation process in the region; Figure 5 It describes the process of resource adaptation and path generation between regions. Assuming that the network initialization has been completed, that is, both the switch and the server have registered relevant (NID, NBD), (SID, SBD) information with the regional controller in the region, and the regional controller has completed the registration and update of the relevant information of the upper controller. In this way, the regional controller has detailed resource distribution and usage in the region, and the root controller has related information such as service resource distribution and regional distribution connection relationship.

Abstract

The invention discloses a resource-aware adaptation method with good scalability. The method includes: each regional controller obtains the information provided by the corresponding service resource entity according to the registration or updated registration information of its subordinate service resource entity. Service resources; the network resource entity under each regional controller updates its status information, topology information, and performance information according to a predetermined resource awareness mechanism to realize dynamic perception of controller resources; each regional controller receives service resources Information and network resource information are summarized and corresponding summary information is generated, and then the summary information is sent out according to the hierarchical relationship until it reaches the root controller; when a certain regional controller receives the interest packet sent by the user, it judges whether the region Have corresponding resources; if yes, perform resource adaptation in the region according to the collected service resources and network resource information; otherwise, send the Interest packet to the upper-level regional controller for inter-regional resource adaptation. By adopting the method disclosed by the invention, the expansibility, service quality and user experience are improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a resource-aware adaptation method with good scalability. Background technique [0002] With the continuous innovation of Internet technology and the continuous expansion of user scale, the traditional Internet has been exposed due to the shortcomings of the original design, such as poor scalability, poor controllability, poor security, etc., and the existing Internet has long been unable to continue to meet To meet the diverse needs of people today, the design of the next generation Internet has become one of the hot issues in academic and industrial research. ICN (Information-Centric Network, Information-Centric Network) and SDN (SoftDefined Network, Software-Defined Network) have attracted much attention as representative solutions. ICN abandons the host-centric communication mode of the traditional Internet, and regards content as the first core element. Users no longer...
