Functions

func AllNodeIDs

func AllNodeIDs() []int32

Return an ordered list of IDs of all known nodes. Every node has a consistent view of this. (At least for now. This might change if we start experimenting with dynamic membership.)

func ClientPubKey

func ClientPubKey(clID int32) interface{}

TODO: Implement proper client public keys, instead of this hard-coded one.

func CorrectPeers

func CorrectPeers() []int32

func Faults

func Faults() int

Returns the the maximum number of faults

func Init

func Init()

Initializes the Client key (to be changed at some point). Cannot be part of the init() function, as the configuration file is not yet loaded when init() is executed.

func InitNodeIdentities

func InitNodeIdentities(identities []*pb.NodeIdentity)

Initializes the known node identities.

func NodeIdentity

func NodeIdentity(nodeID int32) *pb.NodeIdentity

Return full node identity

func NumNodes

func NumNodes() int

Returns the total number of nodes.

func Quorum

func Quorum() int

func SimulatesCrash

func SimulatesCrash(peerID int32) bool

func WeakQuorum

func WeakQuorum() int
