Memory saving packet modification

摘要

The method includes creating a master copy of a header for all packets of a data transmission event, the master copy including a plurality of intact constant header information, the plurality of intact constant header information being constant for all packets of the data transmission event, storing unique header information for all packets of the data transmission event, the unique header information including information unique to at least one packet of the data transmission event, tokenizing identities of each packet of the data transmission event to create a tokenized packet ID for each packet, and indexing the stored unique header information based on the tokenizing. A computer program product for directing a computer processor to perform a method. According to the method, at packet read-time, unique header information associated with the packet is overlayed onto the master copy to create a unique packet.

主权项

1. A computer system, comprising:
a cache memory configured to store unique header information, the unique header information including information unique to at least one packet of a data transmission event associated with the computer system; and a processor, in communication with the cache memory, wherein the computer system is configured to perform a method comprising:
creating a master copy of a header for all packets of the data transmission event, the master copy including a plurality of intact constant header information, the plurality of intact constant header information being constant for all packets of the data transmission event;tokenizing packet IDs of each packet of the data transmission event to create a tokenized packet ID for each packet;indexing the stored unique header information for all packets of the data transmission event in the cache memory based on the tokenizing;retrieving the stored unique header information for a first packet from the cache memory based on the indexing; andcreating the first packet using the master copy of the header and associated unique header information by overlaying the unique header information that was retrieved from the cache memory onto the master copy of the header.
