Method and physical nodes for realizing overlay network load balance

Abstract

The invention discloses a method for realizing overlay network load balance, which comprises that: each physical node detects self node, determines itself as a low-load physical node (L node) or a high-load physical node (H node), and acquires corresponding residual load or overload; the L node informs the neighboring physical node of L node per se and residual load; and when searching that the neighboring physical node has the L node and the residual load of the L node is no less than the overload of the H node, the H node migrates all or partial load of a self virtual VS with highest load factor to the VS of the L node. The invention also discloses the physical nodes for realizing the overlay network load balance at the same time. The scheme of the invention can realize overlay network load balance, has the flexibility of the method adopting the VS, can adapt to the real application scene, and reduces the overhead of maintaining the VS at the same time.

Description

technical field [0001] The invention relates to an overlapping network construction technology in the Internet field, in particular to a method and a physical node for realizing load balancing of an overlapping network. Background technique [0002] With the continuous development of Internet technology, new needs and problems are constantly emerging. Under the premise of keeping the underlying Internet unchanged, overlaying the network to provide the required performance is a method of network evolution. The overlay network architecture is built on the upper layer of the Internet in a seamless and continuous evolutionary manner to form a multi-layer overlay network infrastructure, which can not only provide distributed control and management support for the network for the underlying network operators, but also provide the government with control over the network. The support of behavior supervision and governance can also support various new application services including...

Problems solved by technology

However, this solution is based on the assumption that the size of the resource objects arriving at the system is equal, and the resources are evenly distributed in the address space of the system, which deviates from the real resource object distribution scenario, and cannot avoid VS keeping the route information overhead

Another solution is to use resource migration without using VS. This method can better reflect the real resource distribution scenario, but when resources are frequently migrated, it will bring large bandwidth consumption and index maintenance overhead.
