Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, a method of implementing edge deployment includes the steps of,
establishing a central platform and a plurality of edge servers, interconnecting the edge servers and the central platform to form an edge node network, and interconnecting the central platform and a client;
and setting a load balancing strategy and a content distribution strategy in the central platform to finish edge deployment.
The method for realizing edge deployment of the invention depends on edge servers deployed in various places, and enables users to obtain required contents nearby through a load balancing strategy and a content distribution strategy of a central platform, thereby reducing network congestion and improving access response speed and hit rate of the users.
In this particular embodiment:
preferably, the central platform directs the client's request to the best edge node in the entire edge node network based on the load balancing policy.
Preferably, the optimal edge node is a nearest edge node or a lightest-load edge node.
Load balancing balances a user's requests across multiple remote POPs through a redirection (DNS) mechanism in the content router so that the user's requests are responded to by the nearest content source. The role of load balancing is to direct the user's request to the best edge node in the entire edge node network. The selection of the optimal edge node may be based on a variety of strategies, such as the nearest, lightest loaded, etc. edge node. Load balancing can be generally divided into two levels, global load balancing (GSLB) and local load balancing (SLB). The main purpose of global load balancing is to direct the user's request to the nearest node (or region) across the entire edge node network. Thus, proximity determination is the primary function of global load balancing. Local load balancing is generally limited to a certain area, and the goal is to find a most suitable node to provide service in a specific area. Therefore, the health, load condition, supported media format and other states of the edge node are the main basis for the decision of the local load balancing.
Preferably, the central platform issues or delivers the content to the edge server corresponding to the optimal edge node by establishing methods of indexing, caching, stream splitting, and multicasting based on the content distribution policy.
Preferably, the content distribution policy includes an active distribution policy and a passive distribution policy.
PUSH is a technique of active distribution. Generally, PUSH is initiated by a content management system to distribute content from a source or central media asset repository to Cache nodes at various edges. The distributed protocol may employ HTTP/FTP or the like. The content distributed by the PUSH is generally the content of a hot spot, and the content is pre-distributed (pre) to the edge Cache in a PUSH mode, so that the targeted content provision can be realized. The main issue to consider for PUSH distribution is the distribution strategy, i.e. when and what content is distributed. Generally, content delivery can be determined manually by a CP (content provider) or CDN content administrator, or can be determined in an intelligent manner, so-called intelligent delivery, which determines the process of content delivery according to statistics of user access and predefined rules of content delivery. PULL is a passive distribution technique, which is typically driven by user requests. When the content requested by the user does not exist (miss) on the local edge Cache, the Cache starts the PULL to acquire the content from a content source or other CDN nodes in real time. In PULL mode, the distribution of content is on-demand.
Based on the method for realizing edge deployment, the invention also provides a system for realizing edge deployment.
As shown in fig. 2, a system for implementing edge deployment includes a client, a central platform, and a plurality of edge servers, where the plurality of edge servers and the central platform are interconnected to form an edge node network, the central platform is interconnected with the client, and a load balancing module and a content distribution module are disposed in the central platform.
In this particular embodiment:
preferably, the load balancing module is configured to direct the request of the client to an optimal edge node in the entire edge node network.
Preferably, the optimal edge node is a nearest edge node or a lightest-load edge node.
Preferably, the content distribution module is configured to issue or deliver content to the edge server corresponding to the optimal edge node by establishing an index, a cache, a stream split, and a multicast method.
Preferably, the content distribution module includes an active distribution unit and a passive distribution unit.
The system for realizing edge deployment of the invention depends on edge servers deployed in various places, and enables users to obtain required contents nearby through a load balancing strategy and a content distribution strategy of a central platform, thereby reducing network congestion and improving access response speed and hit rate of the users.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
