Embodiment Construction

[0020] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0021] The present invention provides an embodiment of a resource request method, which is executed by a server as an execution subject, and the method embodiment includes the following process: the DHCPv6 server of the sixth version of the Dynamic Host Configuration Protocol sends the first notification message to the DHCPv6 client , the first notification message carries a first resource status indication; the first resource status indication carries a status code that no resources are available within a specified time; so that the DHCPv6 client passes through the specified The resource request message is sent after the time.

[0022] The present invention also provides another embodiment of the resource request method on the basis of the above embodiments. In this embodiment, the server also performs the following s...

Abstract

The invention relates to a resource request method, a DHCPv6 server and a resource allocation system. The method includes a DHCPv6 server of the sixth version of the Dynamic Host Configuration Protocol sending a first notification message to a DHCPv6 client, the first notification message carrying a first resource status indication; the first resource status indication carrying a specified A status code indicating that no resources are available within the time; so that the DHCPv6 client sends a resource request message after the specified time. The present invention carries the specified time in the notification message, so that the client sends the solicit message after the specified time; reduces unnecessary message interaction overhead between the client / server, reduces network bandwidth load, and avoids constant Handle a large number of invalid request packets to relieve server processing pressure.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource request method, a DHCPv6 server and a resource allocation system. Background technique [0002] In communication networks, the Dynamic Host Configuration Protocol (DHCP) is designed to handle assigning IP addresses and other network information to computers so that computers can communicate automatically on the network. DHCP for IPv6 (DHCPv6) can provide stateful address configuration to IPv6 hosts. [0003] In addition to assigning IP addresses or prefixes to clients, the DHCPv6 server can also provide clients with configuration information such as DNS servers and SNTP servers. The exchange of DHCPv6 stateful messages to obtain IPv6 addresses or prefixes and configuration settings involves the following process: [0004] When the client needs to obtain one or more IP addresses, the client needs to first send a request (Solicit) message to locate the location of the...
