Problems solved by technology

[0004] The local device communicates with the remote device that is not on the same network segment as the local device through the router. The router needs to discover the local device through the routing protocol, and dynamically establish and maintain the destination IP address in the routing forwarding table according to the information provided by the routing message. The entry of the local device increases the overhead of the router

Embodiment 1

[0041] The embodiment of the present invention provides a method for sending IP packets, which can be used in mobile IP scenarios, see figure 2 , figure 2 It is a flowchart of a method for sending an IP packet provided by an embodiment of the present invention, and the method includes:

[0042] 201: The control plane of the router acquires the IP address and the media access control MAC address of the first network element through the point-to-point protocol PPPoE on the Ethernet.

[0043] During specific implementation, the first network element may be a fixed network element or a mobile network element. Wherein, the fixed network element may be a router or a switch. A mobile network element may be a mobile terminal or a virtual machine. The mobile terminal may be a mobile phone, a personal digital assistant (Personal Digital Assistant, PDA) or a portable personal computer (Portable Personal Computer, Portable PC). The first network element may be directly connected to th...

Embodiment 2

[0075] The embodiment of the present invention provides another method for sending IP packets, which can be used in mobile IP scenarios, see image 3 , image 3 It is a flowchart of a method for sending an IP packet provided by an embodiment of the present invention, and the method includes:

[0076] 301: The control plane of the first network element obtains the IP address and the MAC address of the router through PPPoE.

[0077] Regarding the control plane of the first network element obtaining the IP address and MAC address of the router through PPPoE, please refer to 201 in Embodiment 1 for details.

[0078] The IP address of the router may be an IP address of an interface of the router, or may be an IP address of a service of the router. The service may be a video stream service of the router, or an audio stream service of the router. When the IP address of the router is the IP address of the interface of the router, the interface of the router may be a physical interf...

Embodiment 3

[0094] An embodiment of the present invention provides a device for sending IP packets, which can be used in a mobile IP scenario. The means for sending IP packets may be figure 1 in the router. see Figure 4 , Figure 4 It is a schematic diagram of a device for sending IP packets provided by an embodiment of the present invention; the device includes:

[0095] The first obtaining unit 401 is used for the control plane of the router to obtain the IP address and the MAC address of the first network element through PPPoE.

[0096] During specific implementation, the first network element may be a fixed network element or a mobile network element. Wherein, the fixed network element may be a router or a switch. A mobile network element may be a mobile terminal or a virtual machine. The mobile terminal can be a mobile phone, PDA or Portable PC. The first network element may be directly connected to the router. The first network element may also be connected to the router th...

Abstract

The embodiment of the invention provides a method for sending an internet protocol (IP) packet. The method comprises the following steps that: a control plane of a router obtains an IP address and a media access control (MAC) address of a first network element through a point-to-point protocol over Ethernet (PPPoE); the control plane of a router sends the IP address of the first network element down to a router forwarding table so as to generate a first item; the control plane of a router sends the IP address and the MAC address of the first network element down to an address resolution protocol (ARP) cache table so as to generate a second item; The router publishes a route message to a neighboring router of the router; a received source IP address, which is forwarded by the neighboring router, is utilized as a first IP packet of a second network element; and then the router forwards the first IP packet according to the first item and the second item. In addition, the embodiment of the invention also provides a corresponding apparatus. According to the method and the apparatus for sending the internet protocol group provided in the invention, home terminal equipment makes communication with far-end equipment through a router and it is not needed that the router finds the home terminal equipment through a route protocol; moreover, according to information provided by a route message, an object IP address is dynamically established in a rout forwarding table and the object IP address is maintained as an item of the home terminal equipment, thereby reducing costs of the router.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and device for sending Internet protocol packets. Background technique [0002] Currently, the Internet connects many network elements located in different regions. In order to reduce the scale of the network and reduce the cost of management and maintenance, the router divides the entire network into different network segments. The network elements in the same network segment can communicate, and the network elements in different network segments cannot communicate directly. It is necessary for routers to forward Internet Protocol (Internet Protocol, IP) packets. By running routing protocols, such as Internal Gateway Protocol (Internal Gateway Protocol, IGP) and Border Gateway Protocol (Border Gateway Protocol, BGP), network elements in different network segments realize mutual communication. [0003] The inventor finds that the prior art has...
