Problems solved by technology

[0009] Therefore, when a path switching is required, the OFS needs to wait for a path switching instruction from the OFC, and there is a problem that the path cannot be switched at a high speed.

Embodiment approach 1

[0047] In this embodiment, for example, a description will be given of a configuration for securing resources of an relay facility (OFS) used in an SDN network and realizing high-speed path switching at the time of a failure.

[0048] Specifically, in this embodiment, the following structure is described: priority evaluation of alternative paths is performed based on the frequency of use of relay paths, and the free capacity of the flow table of each OFS is considered, and the priority is ranked from high to low. The sequence registration replaces the path.

[0049] According to such a configuration, the resource of the relay device will not be exhausted, and high-speed path switching at the time of failure can be realized.

[0050] figure 1 and figure 2 A system configuration example including the alternative route evaluation device 10 of this embodiment is shown.

[0051] exist figure 1 shows an example of the internal structure of the alternative route evaluation devic...

Abstract

An alternative route evaluation apparatus (10) manages a network including a plurality of basic routes and a plurality of alternative routes. The alternative routes are established for the respective basic routes. Each basic route has, as constitute elements thereof, two or more OFSes (30). Each alternative route has, as constitute elements thereof, a combination of two or more OFSes (30) that is different from that of the respective corresponding basic route. In the alternative route evaluation apparatus (10), a priority evaluation unit (102) sets a priority level for each alternative route on the basis of the amount of a packet relay along the respective corresponding basic route. On the basis of the priority levels set by the priority evaluation unit (102), an alternative route registration unit (103) selects, for each OFS (30), a particular alternative route from among the alternative routes having, as the constitute elements thereof, the OFSes (30).

Description

technical field [0001] The present invention relates to techniques for managing relay paths for relaying packets. Background technique [0002] In recent years, SDN (Software Defined Networking: Software Defined Networking), which manages a network one-dimensionally under software (S / W) control, has attracted attention as a concept for realizing network virtualization. [0003] The SDN is composed of a centralized control device called an SDN controller and a network device (SDN switch) corresponding to the SDN. [0004] By using SDN, it is possible to easily construct a network suitable for load reduction and demand of network change work. [0005] As one of technologies for realizing this SDN, OpenFlow technology has been proposed. [0006] OpenFlow captures communication as an End-to-End flow, and performs path control, failure recovery, load distribution, and optimization in flow units. [0007] OpenFlowSwitch (hereinafter referred to as OFS) functioning as a forwardi...
