Abstract
A method for budgeted learning of link information in a network includes providing a database to contain the link information, for use by an entity connected to the network in transferring traffic over the network, and setting a maximum rate for addition of entries to the database. New entries to be added to the database are determined responsive to the traffic on the network during a learning period. The new entries are added to the database only if the addition of the entries during the learning period has not exceeded the maximum rate.
Claims16
A method for budgeted learning of link information in a network, comprising:
- providing a database to contain the link information, for use by an entity connected to the network in transferring traffic over the network;
- setting a maximum rate for addition of entries to the database;
- responsive to the traffic on the network during a learning period, determining a new entry to be added to the database;
- and
- adding the new entry to the database only if the addition of the entries during the learning period has not exceeded the maximum rate.
A communication device, comprising:
- one or more ports, adapted to send and receive traffic on a network;
- and
- a traffic processor, which is coupled to receive the traffic from the one or more ports, and to process the traffic for further transfer over the network using a database of link information, the traffic processor being further adapted, responsive to the traffic on the network during a learning period, to determine new entries to be added to the database and to add the new entries to the database only if addition of the new entries during the learning period has not exceeded a predetermined maximum rate for the addition of the new entries to the database.
