Embodiment 1

[0037] Such as figure 1 As shown, the transmission network shown in this embodiment includes: ingress servers 102-1 and 102-2, intermediate servers 106-1 to 106-3, and destination server 104. The entry servers 102-1 and 102-2 may send the data access request to the corresponding destination server 104 through one or more of the intermediate servers 106-1 to 106-3. It should be noted,figure 1 The transmission network shown is only an example, and the network topology among the entrance server, the intermediate server, and the destination server can also be other connection methods, and this embodiment does not limit the number of intermediate servers, as an optional In the implementation mode, the entry server can also be directly connected to the destination server.

[0038] based on figure 1 For the transmission network shown, this embodiment also provides an optional data access method, which is described below taking the entry server 102-1 as an example, as figure 2 As ...

Embodiment 2

[0127] This embodiment provides an entry server, taking the entry server 102-1 as an example, as Figure 9 As shown, the ingress server 102-1 in this embodiment includes:

[0128] 1) The first transmission unit 802: used to receive the access request information to be transmitted, wherein the above access request information is used to access data on the destination server;

[0129] 2) Obtaining unit 804: used to obtain link information between the above-mentioned entry server and the above-mentioned destination server, wherein the link information is reported by the configuration system according to the network server including the entry server and the destination server from itself to the set of network servers Delay information and packet loss rate information of other network servers in the network are calculated;

[0130] 3) The second transmission unit 806: configured to send the above access request information to the above destination server according to the above lin...

Abstract

The invention discloses a data accessing method and an entry server. The data accessing method comprises the steps that the entry server receives access request information to be transmitted, and the access request information is used for accessing data on a target server; the entry server obtains link information between the entry server and the target server, wherein the link information is dynamically distributed by a configuration system; the entry server sends the access request information to the target server according to the link information. The data accessing method and the entry server solve the technical problem that due to the fact that a transmitting port of an existing TCP proxy server is fixed in advance, a user can only conduct manual modification and dynamic modification cannot be realized, the link utilization rate is improved through link dynamic distribution and the data transmission speed is improved.

Description

technical field [0001] This application relates to the Internet field, and in particular, relates to a data access method and an entry server. Background technique [0002] In the CDN field, by directing the user's access to the nearest lower-layer TCP proxy server, the lower-layer TCP proxy server accepts the access request from the user by listening to a specific socket (IP address + port), and uses the pre-configured The socket of the upper layer TCP proxy server establishes a connection with the upper layer, then forwards the request to the upper layer, and forwards the response from the upper layer to the user, without analyzing locally. [0003] By building multiple TCP proxy servers on the Internet, through the forwarding of multi-layer TCP proxy servers, users can access the source site, and use high-quality links between TCP proxy servers to realize user accelerated access. [0004] The existing common technology is the TCP proxy forwarding mode. The listening sock...
