Methods and systems for transmitting broadcast data

A method for transmitting broadcast data at a communication gateway, comprising the steps of:

• (a) receiving a broadcast packet from a host or a node;
• (b) determining whether the broadcast packet satisfies at least one condition;
• when the broadcast packet does not satisfy the at least one condition:
• (c) forwarding the broadcast packet to a destination address regardless of TTL value of the broadcast packet;
• when the broadcast packet satisfies the at least one condition:
• (d) determining whether or not TTL of the broadcast packet has expired;
• (e) forwarding the broadcast packet if the TTL of the broadcast packet has not expired;
• (f) not forwarding the broadcast packet if the TTL of the broadcast packet has expired.

A communication gateway capable of transmitting broadcast data comprising:

• a plurality of network interfaces;
• at least one processing unit;
• at least one main memory;
• at least one secondary storage storing program instructions executable by the at least one processing unit for the steps of:
• (a) receiving a broadcast packet from a host or node;
• (b) determining whether the broadcast packet satisfies at least one condition;
• when the broadcast packet satisfies the at least one condition:
• (c) determining whether or not to modify a time to live (TTL) value;
• (d) modifying the TTL value if determined to modify the TTL value;
• (e) forwarding the broadcast packet to a destination address of the broadcast packet based on the TTL value of the broadcast packet;
• wherein the destination address is reachable through an interconnected network.
