Abstract

Abstract A traffic analyzer (16) for a local area network (10) having multiple stations (14) that exchange message packets (24) receives selected ones of the message packets (24). The analyzer (16) stores a message packet table (TABLE(0)-TABLE(6)) and generates a table pointer (P) as a function of both the source address (S) and the destination address (D) of each received packet (24). A record (S,D,N) of each received packet (24) is stored in the table entry (TABLE(P)) associated with the table pointer value (P) for the respective received packet (24), where N is equal to the number of received packets having the source address S and the destination address D.

Claim 6
Dependent Claim 188 words
In a traffic analyzer for a local area network of the type comprising a plurality of stations, each having a respective address, and a transmission medium interconnecting the stations, wherein a first set of the stations each comprise means for sending message packets to selected other ones of the stations via the transmission medium, wherein a second set of stations each comprise means for receiving the message packets, and wherein each of the message packets comprises a source address and a destination address, an improved apparatus for recording information regarding traffic patterns on the transmission medium comprising: means for receiving selected ones of the message packets; means for storing a message packet table comprising a plurality of table entries; means for generating a table pointer as a function of both the source address and the destination address of each of the received packets such that each value of the table pointer is associated with a respective one of the table entries; and means for storing a record of each of the received packets in the table entry associated with the table pointer value for the respective received packet.
Claim 7
Dependent Claim 188 words
In a traffic analyzer for a local area network of the type comprising a plurality of stations, each having a respective address, and a transmission medium interconnecting the stations, wherein a first set of the stations each comprise means for sending message packets to selected other ones of the stations via the transmission medium, wherein a second set of stations each comprise means for receiving the message packets, and wherein each of the message packets comprises a source address and a destination address, an improved apparatus for recording information regarding traffic patterns on the transmission medium comprising: means for receiving selected ones of the message packets; means for storing a message packet table comprising a plurality of table entries; means for generating a table pointer as a function of both the source address and the destination address of each of the received packets such that each value of the table pointer is associated with a respective one of the table entries; and means for storing a record of each of the received packets in the table entry associated with the table pointer value for the respective received packet.
Claim 8
