Abstract

A method of modifying a current version of a configuration of a router includes receiving a modified version of the configuration, loading the modified version of the configuration into memory, and operating the router using the modified version of the router, without rebooting the router.

Claims

1. A method of modifying a current version of a configuration of a router, the method comprising:

receiving a modified version of the configuration;

loading the modified version of the configuration into memory; and

operating the router using the modified version of the router, without rebooting the router.

2. The method of claim 1, wherein loading the modified version of the configuration into memory further comprises:

loading the modified version of the configuration into static memory;

copying the modified version of the configuration from the static memory into dynamic memory; and

replacing the current version of the configuration with the modified version of the configuration, wherein the modified version of the configuration occupies the same position in memory previously occupied by the current version of the configuration.

3. The method of claim 1, wherein receiving the modified version of the configuration further comprises receiving a configuration script from a configuration server.

4. The method of claim 1, wherein receiving the modified version of the configuration comprises receiving modified routing rules.

5. The method of claim 1, wherein receiving the modified version of the configuration comprises receiving modified firewall rules.

6. The method of claim 1, wherein receiving the modified version of the configuration comprises receiving modified port forwarding rules.

7. The method of claim 1, wherein the router includes a Linux kernel.

8. The method of claim 1, wherein the router includes a Linux kernel and the modified version of the configuration is included in the Linux kernel.
