Types

type Locator

type Locator struct {
	// contains filtered or unexported fields
}

Locator helps to find a caching server for any given DUT. It tries to use UFS zone and falls back to subnets to match the given DUT with a caching server. It caches intermediate results, e.g. IP addresses, UFS zones, etc.

func NewLocator

func NewLocator() *Locator

func (*Locator) FindCacheServer

func (l *Locator) FindCacheServer(dutName string, client ufsapi.FleetClient) (*labapi.IpEndpoint, error)

FindCacheServer returns the ip address of a cache server mapped to a dut.

func (*Locator) SetPreferredServices

func (l *Locator) SetPreferredServices(services []string) error

SetPreferredServices sets preferred services form a string slice.

type Subnet

type Subnet struct {
	IPNet    *net.IPNet
	Backends []address
}

Subnet is a network in labs (i.e. test VLAN). DUTs can only access caching backends in the same Subnet.
