Constants

const (
	// BUFFERSIZE represents a size of read buffer.
	BUFFERSIZE = 1500
	// MTU represents a maximum transmission unit.
	MTU = "1300"
	// IPv4 represents a version of IP address
	IPv4 = "IPv4"
	// IPv6 represents a version of IP address
	IPv6 = "IPv6"
)

I use TUN interface, so only plain IP packet, no ethernet header + mtu is set to 1300

Variables

var CBLogger *logrus.Logger

CBLogger represents a logger to show execution processes according to the logging level.

Types

type CBNetwork

type CBNetwork struct {
	// Variables for the cb-network
	NetworkingRule model.NetworkingRule // Networking rule for a network interface and tunneling
	ID             string               // ID for a cloud adaptive network

	// Variables for the cb-network agents
	HostID                  string   // HostID in a cloud adaptive network
	HostPublicIP            string   // Inquired public IP of VM/Host
	HostPrivateIPv4Networks []string // Inquired private IPv4 networks of VM/Host (e.g. ["192.168.10.4/24", ...])
	Interface               *os.File // Assigned cbnet0 IP from the controller
