Embodiment Construction

[0061] Aiming at the problem of how to maintain these software routing tables and hardware routing tables in the prior art to ensure the normal communication of the VXLAN network, the embodiment of the present invention provides a VTEP-based routing table maintenance method, which is applied to each VTEP included in the VXLAN network Each VTEP includes a hardware routing table and a software routing table, and the method in this embodiment is to realize the maintenance of the hardware routing table and the software routing table. The procedure of this method is as follows figure 2 As shown, the specific execution steps are as follows:

[0062] S21: Monitor whether the first number of hardware routing table items included in the hardware routing table reaches the maximum capacity of the hardware routing table, and if the first number does not reach the maximum capacity, select a software route that does not exist in the hardware routing table from the software routing table A...

Abstract

The invention discloses a VTEP (Virtual eXtensible Local Area Network Tunnel End Point)-based routing table maintenance method and device. The method includes: monitoring whether first quantity of hardware routing entries included by a hardware routing table reaches maximum capacity, and if the maximum capacity is not reached, selecting a software routing entry from a software routing table to addthe same into the hardware routing table; monitoring whether each hardware routing entry is hit in an aging period, updating a continuous not-hit period and a first hit identifier of each hardware routing entry, and deleting hardware routing entries, of which continuous not-hit periods exceed a first set threshold, in the hardware routing table and corresponding software routing entries thereof in the software routing table; and monitoring whether each software routing entry is hit in the aging period, updating a continuous not-hit period and a second hit identifier of each software routing entry, and deleting software routing entries, of which continuous not-hit periods exceed a second set threshold, in the software routing table. The solution can better maintain the hardware routing table and the software routing table.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for maintaining a routing table based on a virtual extensible local area network tunnel terminal (VirtualeXtensible Local Area Network Tunnel End Point, VTEP). Background technique [0002] Virtual Extensible Local Area Network (Virtual eXtensible Local Area Network, VXLAN) is an overlay (Overlay) network technology built on the Internet Protocol (Internet Protocol, IP) network, which uses Media Access Control (MAC) in (in) encapsulation by means of User Datagram Protocol (UDP), that is, encapsulating ordinary Ethernet packets in UDP packets, and transmitting ordinary Ethernet packets as UDP data. A VXLAN network is uniquely identified by a VXLAN Network Identifier (VNI). Terminals on VXLAN networks of different VNIs cannot communicate directly, and a VXLAN gateway route is required. [0003] like figure 1 The architecture diagram of the VXLAN...
