Class SFFTable

java.lang.Object

siena.fwd.SFFTable

All Implemented Interfaces:

ForwardingTable

public class SFFTable
extends java.lang.Object
implements ForwardingTable

implementation of the Siena Fast Forwarding (SFF) algorithm. This implementation of the forwarding table and its matching algorithm is based on the data structure and algorithm described in A. Carzaniga and A.L. Wolf, "Forwarding in a Content-Based Network". Proceedings of ACM SIGCOMM 2003. A more complete and advanced implementation is available in C++ here.

Method Detail

consolidate

public void consolidate()

Specified by:

consolidate in interface ForwardingTable

clear

public void clear()

Description copied from interface: ForwardingTable

clears the forwarding table. Removes every association of predicates and interfaces. After the execution of this method, the forwarding table is ready to be rebuilt from scratch.

Specified by:

clear in interface ForwardingTable

match

public void match(Message m,
         MatchMessageHandler p)

Description copied from interface: ForwardingTable

matches a message against the proedicates in the table. For each matching predicate, this method delegates the execution of a specific action to the given match handler.

Specified by:

match in interface ForwardingTable

See Also:

MatchMessageHandler

match

public void match(Message m,
         MatchHandler p)

Description copied from interface: ForwardingTable

matches a message against the proedicates in the table. For each matching predicate, this method delegates the execution of a specific action to the given match handler.

Specified by:

match in interface ForwardingTable

See Also:

MatchHandler

ifconfig

public void ifconfig(java.lang.Object ifx,
            Predicate p)
              throws BadConstraintException

Description copied from interface: ForwardingTable

associates an interface with a predicate This is the main method that builds the forwarding table. It associates an interface object with a predicate. Notice that this forwarding table is a dictionary-type data structure, which means that this method may be called only once for each inteface object. If you need to modify the predicate associated with an interface, you must rebuild the entire forwarding table.

Specified by:

ifconfig in interface ForwardingTable

Throws:

BadConstraintException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
