NL_S_ISSlicePath

Perform the overlay path followed by an information slice towards an overlay node.

Calling Sequence

[P] = NL_S_ISSlicePath(I,S,R,N,D)

Arguments

I :

Destination overlay node.

S :

Slice index destined to I.

R :

Routing table.

N :

Quantity of nodes of the overlay topology.

D :

Number of slices.

P :

Path within the overlay graph.

Description

NL_S_ISSlicePath performs the overlay path P followed by the information slice S towards the overlay node I within the overlay graph composed by N nodes. R provides the routing table, e.g. the path followed by each slice along the overlay network. D is the number of slices.

Information Slicing is a new approach to anonymous communication (WEB). The physical topology, where data are propagated, is called the underlay network. The virtual network named overlay, is built on top of the underlay network. It is working like a Peer-2-Peer network and its goal is to provide source and destination anonymity and churn resilience, without using any public key cryptography. For that purpose, a set of overlay nodes are selected and forms a lattice composed by D lines of ln overlay nodes.

In the previous example, D=3 and ln=5.

Examples

n=200;//network size
l0=3;//a maximum of 5 links are created for each created node
Ls=1000;//network square area side 
[g,dist]=NL_T_BarabasiAlbert(n,l0,Ls);//generation of the underlay topology
ln=5;//number of nodes per line
L=ln-1;//hop length
d=3;//number of slices
np2p=ln*d;//quantity of nodes of the overlay topology
[go,p2plist,routetab,T]=NL_S_ISUL2OL(g,np2p);//selection of overlay nodes
[gol]=NL_S_ISOverlay(ln,d,T);//creation of the overlay topology
w1=1;//window index
NL_G_ShowGraph(go,w1);//graph visualization
w2=2;//window index
NL_G_ShowGraphN(gol,w2);//graph visualization
[OLRT,OLpres]=NL_S_ISOLSliceProp(np2p,d,T);//propagation of slices
sn=NL_F_RandInt1n(np2p);//node of interest at the overlay: study of all IP information crossing this node
dn=d+NL_F_RandInt1n(np2p-d);//destination node at the overlay level
w3=3;//window index
col=[1 2 3 5 6 7 9 10 11];//color
[gg]=NL_S_ISMultiPath(dn,np2p,d,gol,col);//splice propagation within the overlay graph
NL_G_ShowGraphN(gg,w3);
si=NL_F_RandInt1n(d);//slice index
OLi=dn;//destination overlay node
[spath]=NL_S_ISSlicePath(OLi,si,OLRT,np2p,d)//application of NL_S_ISSlicePath
