Resource perception adaption method with good expandability

Abstract

The invention discloses a resource perception adaption method with good expandability. The resource perception adaption method comprises the steps that: each region controller obtains service resources provided by a corresponding service resource entity according to registration of a service resource entity belonging to the region controller or updated registration information; a network resource entity under each region controller updates state information, topological information and performance information according to a preset resource perception mechanism, and realizes controller resource dynamic perception; each region controller collects the received service resource information and network resource information and generates corresponding summary information, and outwards send the summary information according to a hierarchical relationship until the summary information reaches a root controller; when one region controller receives an interest packet sent by a user, the region controller determines whether the region controller has corresponding resources or not; if yes, performing resource adaption in the region according to the collected service resources and network resource information; and if not, sending the interest packet to a superior region controller to perform inter-region resource adaption. By adopting the method disclosed by the invention, the expandability, the service quality and the 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 (Soft Defined 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 longe...

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.
