Embodiment

[0070] Since the AS (Autonomous System, autonomous system) basically reflects the regional attributes of the network in actual network deployment, and the area range of this area and the PID basically overlaps, so according to the AS of BGP (Border Gateway Protocol, Border Gateway Protocol) to automatically It is reasonable to divide the PID. Such as figure 1 As shown, this embodiment provides an ALTO server, including:

[0071] A routing request module, configured to send a routing request to the BGP module;

[0072] Wherein, when the routing request module sends the routing request to the BGP module, it may indicate whether the requested original BGP route or aggregated route is requested.

[0073] A routing receiving module, configured to receive routing information returned by the BGP module;

[0074] The PID division module is configured to, after receiving the routing information returned by the BGP module, divide the terminal into multiple PIDs according to a preset ...

Abstract

The invention discloses a method and an apparatus for dividing a provider-defined network location identifier (PID), as well as an application-layer traffic optimization (ALTO) server and a border gateway protocol (BGP) module, wherein the method comprises the following steps that a route request is sent to the border gateway protocol module by the ALTO server; the route information is returned to the ALTO server after the route request which is sent by the ALTO server is received by the BGP module, the route information carries a route of a terminal and a source autonomous system (AS) serial number; and after the route information which is returned by the BGP module is received by the ALTO server, the terminal is divided into multiple PIDs by the ALTO server in accordance with a preset PID division strategy depending on the route of the terminal as well as the source AS serial number carried in the route information. According to the method and the apparatus, the ALTO server and the BGP module, PIDs are automatically divided with the help of the route information of the BGP and the source AS information, so that the labor is saved; moreover, the operation of PID division is intelligent, has few errors and is simple and feasible.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for dividing PID (Provider-defined Network Location identifier, provider-defined network location identifier), ALTO (Application-Layer Traffic Optimization, application layer transmission optimization) server and BGP ( Border Gateway Protocol, Border Gateway Protocol) module. Background technique [0002] At present, there are a large number of applications that need to select a suitable node from one or more candidate hosts to obtain the required resources, such as P2P (Peer-to-Peer, point-to-point) applications, CDN (Content Delivery Network, content distribution network) selection, mirror selection etc. 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] The ALTO service mainly divides the terminal into multiple PIDs according to ...
