This results in an unavoidable trade-off between latency and overhead in a packet based channel aggregation protocol. (...) Transparency control overhead can be kept very small by using a sufficiently large flag. The overhead due to model updates can be kept very low since these updates will typically be needed infrequently.

This would increase the link layer overhead and thereby decrease the effective payload rate. (...) The scheme also requires an initialization period, where all headers are sent uncompressed, this time is approximately the round-trip time of the connection. Packetization overhead in UMTS protocol stack: · Overhead per RLC PDU = RLC frame header (4 bytes) = 4 bytes · Overhead per PDCP PDU = PDCP packet header (1 byte) + length info (1 byte) = 2 bytes Packetization overhead in CDMA-2000 protocol stack: · Overhead per RLC PDU = RLC frame header (2 bytes) = 2 bytes · Overhead per PPP PDU = PPP packet header (3 bytes) + bit stuffing (~2% of payload)+compressed RTP/UDP/IP header (3 bytes) Simulation Software Simulation software will be available on the standard ftp-site. (...) It is up to the experimenter to ensure, that the packetized video stream with the added simulator packetization overhead and optional RLC retransmission overhead fits into the available radio bearer.

The bigger data quantum could result in unwanted memory bandwidth overhead while the data is being transferred. Additional memory cycles may be required when the data to be referenced is lying across different memory banks. (...) Based on the extended block partition, the overhead ratio relative to each block size is calculated in Table 1, where the overhead ratio is defined as follows: (overhead ratio) = (# of needed pixels for interpolation of a block partition) / (# of pixels of a block partition).
