Abstract
The invention is directed to methods, apparatus and systems for processing a data packet that has a destination address. In the event that in a routing table cache and in a routing table, there is no entry with a destination address prefix that is a prefix of the destination address, a default-route-prefix is determined in a default-route determination step.
Claims17
A method comprising:
- processing a data packet, having a destination address (d), towards a routing destination;
- and
- determining a default-route-prefix (Pd) in a default-route determination step, when in a routing table cache (L1) and in a routing table (L2), there is no entry with a destination address prefix that is a prefix of the destination address (d).
A method comprising:
- processing a data packet, having a destination address (d), towards a routing destination, wherein a default-route-prefix (Pd) resides together with a default routing destination as an entry in a routing table cache (L1);
- and
- forwarding the data packet to said default routing destination, when the default-route-prefix (Pd) matches at least part of said destination address (d).
An apparatus comprising:
- means for processing a data packet, having a destination address (d), towards a routing destination;
- and
- means for determining a default-route-prefix (Pd) in a default-route determination step, when in a routing table cache (L1) and in a routing table (L2), there is no entry with a destination address prefix that is a prefix of the destination address (d).
