Abstract

Here we have a router virtual machine on which many routing applications based on different routing algorithms run. When a packet arrives at the router virtual machine, the Core Routing module routes the packet if the router virtual machine's IP address is not the destination IP address of the packet else if the router virtual machine's IP address is the destination IP address of the packet it forwards the ownership of the packet to the Data Mover module which pushes the packet to a special Virtual Interface assigned for routing applications running on the router virtual machine. An interrupt is generated just like for any other interface when the packet is pushed to the Virtual Interface and packet is copied in the appropriate kernel buffer of the socket pertaining to the routing application.

Description

Virtual Interface for Routing Applications
In this invention we have a router virtual machine on which many routing applications based on different routing algorithms run. When a packet arrives at the router virtual machine, the Core Routing module routes the packet if the router virtual machine’s Internet Protocol (IP) address is not the destination Internet Protocol (IP) address of the packet else if the router virtual machine’s Internet Protocol (IP) address is the destination Internet Protocol (IP) address of the packet it forwards the ownership of the packet to the Data Mover module which pushes the packet to a special Virtual Interface assigned for routing applications mnning on the router virtual machine. An interrupt is generated just like for any other interface when the packet is pushed to the Virtual
Interface and packet is copied in the appropriate kernel buffer of the socket pertaining to the routing application.

Claims

Claims Following is the claim for this invention: -
1. In this invention we have a router virtual machine on which many routing applications based on different routing algorithms run. When a packet arrives at the router virtual machine, the Core Routing module routes the packet if the router virtual machine’s Internet Protocol (IP) address is not the destination Internet Protocol (IP) address of the packet else if the router virtual machine’s Internet Protocol (IP) address is the destination Internet Protocol (IP) address of the packet it forwards the ownership of the packet to the Data Mover module which pushes the packet to a special Virtual Interface assigned for routing applications running on the router virtual machine. An interrupt is generated just like for any other interface when the packet is pushed to the Virtual Interface and packet is copied in the appropriate kernel buffer of the socket pertaining to the routing application. The above novel technique of pushing packets related to routing applications in the kernel space of the router virtual machine is the claim for this invention.
