Method Detail

compactLinkString

public static String compactLinkString(Link link)

Returns a compact identity for the given link, in the form used to identify links in the Topology View on the client.

Parameters:

link - link

Returns:

compact link identity

canonicalLinkKey

public static LinkKey canonicalLinkKey(Link link)

Produces a canonical link key, that is, one that will match both a link and its inverse.

Parameters:

link - the link

Returns:

canonical key

formatBytes

public static TopoUtils.ValueLabel formatBytes(long bytes)

Returns a value representing a count of bytes.

Parameters:

bytes - number of bytes

Returns:

value representing bytes

formatPacketRate

public static TopoUtils.ValueLabel formatPacketRate(long packets)

Returns a value representing a count of packets per second.

Parameters:

packets - number of packets (per second)

Returns:

value representing packets per second

formatClippedBitRate

public static TopoUtils.ValueLabel formatClippedBitRate(long bytes)

Returns a value representing a count of bits per second, (clipped to a maximum of 100 Gbps). Note that the input is bytes per second.

Parameters:

bytes - bytes per second

Returns:

value representing bits per second

formatFlows

public static String formatFlows(long flows)

Returns human readable flow count, to be displayed as a label.

Parameters:

flows - number of flows

Returns:

formatted flow count
