Functions ¶
func FindIndex ¶
func FindIndex(indices IndicesInterface, idx reservation.IndexNumber) (int, error)
FindIndex returns the slice index for the passed IndexNumber.
func SortIndices ¶
func SortIndices(idxs IndicesInterface)
SortIndices sorts these Indices according to their index number modulo 16, e.g. [14, 15, 0, 1].
func ValidateIndices ¶
func ValidateIndices(indices IndicesInterface) error
ValidateIndices checks that the indices follow consecutive index numbers, their expiration times are greater or equal, and no more than three indices per expiration time. Also no more than 16 indices are allowed.
Types ¶
type Capacities ¶
type Capacities interface {
IngressInterfaces() []uint16
EgressInterfaces() []uint16
Capacity(from, to uint16) uint64
CapacityIngress(ingress uint16) uint64
CapacityEgress(egress uint16) uint64
}
Capacities describes what a capacity description must offer.
type ColibriPath ¶
type ColibriPath interface {
Copy() ColibriPath
// Reverse reverses the contained path.
Reverse() error
NumberOfHops() int
IndexOfCurrentHop() int
IngressEgressIFIDs() (uint16, uint16)
}
ColibriPath is a path of type COLIBRI. This type will be moved to its right place in slayers once the header has been approved. TODO(juagargi): move the type to slayers.
type IndicesInterface ¶
type IndicesInterface interface {
Len() int
GetIndexNumber(i int) reservation.IndexNumber
GetExpiration(i int) time.Time
GetAllocBW(i int) reservation.BWCls
GetToken(i int) *reservation.Token
Rotate(i int) IndicesInterface
}
type MessageWithPath ¶
type MessageWithPath interface {
Path() ColibriPath
}
MessageWithPath is used to send messages from the COLIBRI service via the BR.
type RequestMetadata ¶
type RequestMetadata struct {
// contains filtered or unexported fields
}
RequestMetadata contains information about the request, such as its forwarding path. This base struct can be used by any request or response packets.
func NewRequestMetadata ¶
func NewRequestMetadata(path ColibriPath) (*RequestMetadata, error)
NewRequestMetadata constructs the base Request type.
func (*RequestMetadata) IsLastAS ¶
func (m *RequestMetadata) IsLastAS() bool
IsLastAS returns true if this hop is the last one (this AS is the destination).
func (*RequestMetadata) Path ¶
func (m *RequestMetadata) Path() ColibriPath
Path returns the ColibriPath in this metadata.
