Title:
METHOD AND APPARATUS FOR CONVERTING DATA PACKETS BETWEEN A HIGHER BANDWIDTH NETWORK AND LOWER BANDWIDTH NETWORK
Document Type and Number:
WIPO Patent Application WO2003009502
Kind Code:
A3
Abstract:
A method and apparatus for converting bursty, packetized data traffic from a wide bandwidth network to a constant, average rate traffic on a payload network having a narrower bandwidth is disclosed. The method includes converting a packet burst received from the wide bandwidth network to a serial stream having first and second pluralities of bytes, the second plurality of bytes having only idle bytes; substituting a place keeping flag for said second plurality of bytes thereby providing a reduced data; encapsulating the reduced data in a second packet; and providing the second packet to the narrower bandwidth network at a constant, average traffic rate. The method also includes converting the second packet received from the narrower bandwidth network to a second serial stream; substituting a plurality of idle bytes for the place keeping flags; converting the second serial stream and substituted idle bytes to a third packet; and providing the third packet to the wide bandwidth network.
