Problems solved by technology

[0005] However, in a specific network, for example, in an environment where the Point-to-Point Protocol (PPP) is applied, only the PPP protocol is run to obtain the network address of the host, and there is no DHCP server, so it is impossible to pass the DHCP at this time. Obtaining the domain name of the access network through a different method, resulting in the inability to complete the discovery of the ALTO server through DHCP
[0006] Aiming at the problem that the ALTO server cannot be discovered through DHCP in the PPP protocol in the prior art, no effective solution has been proposed yet

Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] figure 1 is a flow chart of a method for discovering an application layer transmission optimization server according to an embodiment of the present invention, such as figure 1 As shown, the method mainly includes the following steps (step S102-step S104):

[0026] Step S102, the application layer transmission optimization (ALTO) client obtains the access network domain name configured by the PPP server through information interaction under the PPP protocol with the point-to-point (PPP) server;

[0027] Step S104, the ALTO client obtains the universal resource identifier (URL) of the ALTO server according to the domain name of the access network.

[0028] In this embodiment, step S102 can b...

Abstract

The invention discloses a method and a device for discovering an application layer transmission optimization server. Among them, the method includes: the application layer transmission optimization (ALTO) client obtains the access network domain name configured by the PPP server through information interaction under the PPP protocol with the point-to-point (PPP) server; Get the Universal Resource Identifier (URL) of the ALTO server. Through the present invention, the discovery of the ALTO server can also be completed in the PPP protocol.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for discovering an application layer transmission optimization server. Background technique [0002] At present, a large number of applications need to select a suitable node from one or more candidate hosts to obtain the resources they need, such as: Peer-to-Peer (P2P) applications, Content Delivery Network (ContentDeliveryNetwork, CDN for short) selection, mirror selection, etc. The role of the Application-Layer Traffic Optimization (ALTO for short) server is to provide network-related information support for these applications, so as to guide the applications to select candidate nodes more reasonably. ALTO technology is based on the client / server (Client / Server, referred to as C / S) structure. The ALTO client obtains the guidance information of the relevant candidate nodes from the ALTO server. First, the ALTO client needs to be able to discover the ALTO s...
