X-BeenThere: ovs-dev@openvswitch.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: ovs-dev-bounces@openvswitch.org Sender: "dev" From: Gongming Chen This patch merges ipv4 addresses with wildcard masks, and replaces this ipv4 addresses with the combined ip/mask. This will greatly reduce the entries in the ovs security group flow table, especially when the host size is large. Analysis in the simplest scenario, a network 1.1.1.0/24 network,create 253 ports(1.1.1.2-1.1.1.254). Only focus on the number of ip addresses, the original 253 addresses will be combined into 13 addresses. 1.1.1.2/31 1.1.1.4/30 1.1.1.8/29 1.1.1.16/28 1.1.1.32/27 1.1.1.64/26 1.1.1.128/26 1.1.1.192/27 1.1.1.224/28 1.1.1.240/29 1.1.1.248/30 1.1.1.252/31 1.1.1.254 Some scenes are similar to the following: 1.1.1.2, 1.1.1.6 After the combine: 1.1.1.2/255.255.255.251 You can use ovn-match-ip utility to match ip. such as: ovs-ofctl dump-flows br-int | ovn-match-ip 1.1.1.6 1.1.1.2/255.255.255.251 will show. Simple description of the algorithm. There are two situations 1. Combine once such as: 1.1.1.0 1.1.1.1 1.0.1.0 1.0.1.1 Combined into: 1.1.1.0/31, 1.0.1.0/31 2. Combine multiple times 1.1.1.0 1.1.1.1 1.0.1.0 1.0.1.1 Combined into: 1.0.1.0/255.254.255.254 Considering the actual scene and simplicity, the first case is used to combine once. ...00... ...01... ...10... ...11... "..." means the same value omitted. Obviously, the above value can be expressed as ...00.../11100111. This continuous interval that can be represented by one or several wildcard masks is called a segment.
