Problems solved by technology

[0005] As shown in Figure 1-b, for each service request, the ALTO client sends a query request to the ALTO server to obtain the latest network mapping table and path cost table, assuming that under the ALTO architecture, the mapping information has not changed for a long period of time Or update, obviously there are a lot of redundant query request / response interaction messages between ALTO client and ALTO server, these redundant query request / response interaction messages occupy a lot of limited bandwidth resources and aggravate ALTO server load

example 3

[0157]512. Based on the relationship between the PID and the expiration time parameter, the ALTO client performs expiration verification on the Network Map. If the mapping information related to PID1 and PID2 in the Network Map expires and fails, an HTTP POST is sent to the ALTO server. The HTTP POST carries PID1 and PID2 to request the ALTO server to return the Filtered Network Map (that is, the mapping information related to PID1 and PID2, the mapping information related to PID1 and PID2 contains the corresponding expiration time parameters), see Example 3 in Section 2.2 below;

[0158] Specifically, the query request for the Filtered Network Map may also be an HTTP GET message.

[0159] 513. The ALTO client receives the 200OK returned by the ALTO server, and the 200OK carries a Filtered Network Map, wherein the Filtered Network Map has an expiration time parameter;

[0160] 514. The ALTO client updates the stored Network Map at the entire network layer level, and establishe...

[0181] 2.2. The following example shows the scenario where the ALTO client queries the Filtered Network Map with HTTP POST and the ALTO server returns the Filtered Network Map with an expiration time parameter. The ALTO client establishes the association between the subnetwork level mapping information and the expiration time parameter. Once expired, the ALTO client initiates a new query only for mapping information at the subnetwork level, thereby avoiding additional load on the network.

Abstract

The embodiment of the invention discloses a transmission optimization method, a mapping information storage method, an application layer traffic optimization (ALTO) client, an ALTO server and an ALTO system. The transmission optimization method comprises the following steps of: when a next-hop node is required to be determined for service, checking whether a storage system associated with the ALTO client stores mapping information or not; and if the storage system associated with the ALTO client stores the mapping information of a first sub-network level and the mapping information of the first sub-network level is unexpired and valid, determining a next-hop node set on the basis of an information source comprising the network address of a service request node and the mapping information of the first sub-network level, wherein the next-hop node set comprises one or more service provision nodes, and the service request node belongs to a first sub-network. Therefore, the consumption of redundant query request and response message interaction between the ALTO client and the ALTO server in the traffic of the whole backbone network is reduced, and the load of the backbone network is reduced.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a transmission optimization method, a storage method, device and system for mapping information. Background technique [0002] Distributed applications such as file sharing, streaming media broadcast or on-demand, voice communication and online game support platforms generally use a considerable amount of network resources on the network. Usually, these applications transmit a large amount of data by establishing connections between nodes distributed throughout the network. Most applications randomly select a subset from a large set of nodes to exchange data, and the underlying network topology is known. very little. As shown in Figure 1-a, many current P2P (Peer to Peer, peer-to-peer network) systems directly form an overlay network by peer-to-peer connections, and the overlay network is composed of nodes distributed in multiple service provider network ISPs , when two node p...
