Scalable error detection for packet-switched transmission

For providing improved flexible error detection system and method in aggregate of the packet-switched transmission. In one embodiment, a telescopic is Holland checking DC transformer is such groove core layer and an application layer and detects error, wherein discards automatic depuration Holland one or multiple reinforced layers connected with varying the CRC and value. For transmitting of a single checking and installed in the load-reducing masthead or the underlying three protocol's masthead. The sending revised the code bit stream of such manner, wherein deploys telescopic is Holland, and no need to recomputate is arranged from packet removal layer the entity the network in only CRC of load-reducing or packet masthead, a work and without the load-reducing and exchange. Prefix/tail Bit field is increased to the edge of the reinforcing layer is a ending to make the checking and checking and public CRC and matched and. In one embodiment, a receiver capable of verify layer precision of each receiving, and a expected, which is made from a layer of data receiving correctly.
