Embodiment Construction

[0072] A method, device and system provided by the present invention will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

[0073] The load balancing method provided by the embodiment of the present invention is further improved on the basis of the existing network architecture of the PMIPv6 domain.

[0074] figure 2 It is a schematic diagram of a new PMIPv6 network architecture provided by the embodiment of the present invention, and multiple LMAs and a new network entity—routing management entity—are introduced into the PMIPv6 network domain.

[0075] For illustration, figure 2 Only two LMAs (LMA1 and LMA2) are identified in , and the embodiment of the present invention does not limit the number of LMAs.

[0076] In the load balancing method provided by the embodiment of the present invention, multi-tunnels need to be established between the LMA and the MAG in advance, that is, a process in which each MAG interacts wi...

Abstract

The invention discloses a method, a system and a device for load balancing, which are applied to a proxy mobile IPv6 network. The method comprises the following steps that: a routing management entity periodically reports load information according to each local mobile anchor point (LMA) and determines an overload LMA and a light load LMA; and the routing management entity notifies a mobile access gateway (MAG) which forwards data through the overload LMA to adjust data forwarding routing to ensure that the MAG changes the data required to be forwarded by the overload LMA into the data forwarded by the light load LMA. The method, the system and the device improve the architecture of the existing proxy mobile IPv6 network, and perform the balancing of data forwarding amount between the overload LMA and the light weight LMA by adopting a plurality of the LMA and a newly-added network entity namely the routing management entity and adjusting the data forwarding path of the MAG, so the load balancing of the LMA can be realized dynamically in real time.

Description

technical field [0001] The invention relates to a proxy mobile IPv6 (Internet Protocol Version 6) network, in particular to a load balancing method, device and system. Background technique [0002] In the next generation of mobile Internet, due to various disadvantages brought about by global mobility, such as high signaling overhead and the need to modify the host, the International Standards Organization Internet Engineering Task Force IETF currently proposes a draft network-based regional mobility management protocol: Proxy Mobility IPv6 (Proxy Mobile IPv6, PMIPv6). [0003] In the definition of PMIPv6, the network area that uses the PMIPv6 protocol to handle the mobility management behavior of a mobile node is called Proxy Mobile IPv6 Domain (hereinafter referred to as PMIPv6 domain). figure 1 It is an example of the structure of the existing PMIPv6 domain. In this domain, the core functional entities include a local mobility anchor (Local Mobility Anchor, LMA) and mult...
