Class benno.submerge.Zone 

java.lang.Object
   |
   +----benno.submerge.Zone
public class Zone
extends Object
implements Serializable
This is a zone of allocation. It consists of a list of networks provided by an upstream entities and then a list of allocations to downstream entities

Constructor Index

o Zone(String)

Method Index

o addDownstream(Network)
allocates network n in the downstream network.
o addUpstream(Network)
o countFree(int)
counts the free networks with a mask length of 'bits'
o findFree(int)
Locates a free network with 'bits' network bits.
o numAddrs()
sums the numAddrs for all of the upstream networks
o optimiseFreestream()
This scans the freestream vector merging adjacent networks into supernets.
o toString()

Methods

o toString 
 public String toString()
Overrides:
toString in class Object
o addUpstream 
 public void addUpstream(Network n)
o addDownstream 
 public void addDownstream(Network n)
allocates network n in the downstream network. As necessary, it splits up networks in the freestream to do this.

o numAddrs 
 public int numAddrs()
sums the numAddrs for all of the upstream networks

o countFree 
 public int countFree(int bits)
counts the free networks with a mask length of 'bits'

o findFree 
 public Network findFree(int bits)
Locates a free network with 'bits' network bits. Works by looking at all subnets of each upstream network, and testing to see if any downstream networks intersect.

o optimiseFreestream 
 public void optimiseFreestream()
This scans the freestream vector merging adjacent networks into supernets. The algorithm is: for each network in the freestream: check for the existence of a network with the last network bit flipped. if exists, replace both networks by a supernet 1-bit larger.
