Embodiment Construction

[0035] This embodiment defines a new device, that is, the ALTO controller, and the ALTO controller supports the function of communicating with the ALTO server. The main function is to deliver uniformly configured policies to the ALTO server, and communicate network information, cost information between ALTO servers, and local policies within the PID network that the ALTO server is responsible for.

[0036]The ALTO controller is used to connect with each ALTO server within the network range it is in charge of. Specifically, ALTO servers are deployed inside each PID network, and ALTO controllers are set at a higher network level. Each ALTO server is responsible for collecting network information inside the PID network, and then informs the ALTO controller of the network information and local policies. The ALTO controller sends the network information and local policies to each ALTO server. The ALTO server calculates the cost information from the PID network it is in charge of ...

Abstract

The invention discloses a method and system for implementing application layer transmission optimization, comprising: an application layer transmission optimization (ALTO) controller connects to the ALTO controller and is responsible for network location identification (PID) networks defined by different suppliers. The server receives network information and local policies, and sends network information and policies to each ALTO server connected to the ALTO controller; after the ALTO controller sends network information and policies, it receives the ALTO server responsible for each ALTO service The PID network of the ALTO controller reaches the cost information of other PID networks under the ALTO controller, and sends the received cost information to each ALTO server connected to the ALTO controller.

Description

technical field [0001] The present invention relates to the field of network transmission, in particular to a method and system for realizing ALTO (Application-Layer Traffic Optimization, application-layer traffic optimization). Background technique [0002] At present, there are a large number of applications that need to select the appropriate node from one or more candidate hosts to obtain the required resources, such as P2P (Peer-to-Peer) applications, CDN (Content Delivery Network, content delivery network) selection, mirror selection Wait. The purpose of ALTO is to provide these applications with network-related information support to guide applications to make more reasonable choices for candidate nodes. [0003] At this stage, most of the considerations in ALTO deployment and application scenarios are that a network of a single ISP (Internet Service Provider) uniformly uses an ALTO server to guide all terminal requests. It can meet the requirements in a network env...
