transmission header
1.In SNA, the forwarding of a message unit alonga particular path through a network, as determined by parameters carried in the message unit, such as the destination network address in a transmission header.
2.In transmission systems,burst packets(BPs) over burst packets optical wavelength channels choose 1 550 nm band,and burst header packet(BHPs) over control optical wavelength channel use 1 310 nm band.
3.The identifier is part of the 16-bit 802.1Q header, which is added to the MAC transmission frames used in Ethernet and token-ring networks.
4.After analyzing the symbol structure of pulse position modulation (PPM), digital pulse interval modulation (DPM) and dual-header pulse interval modulation(DH-PIM) in detail, the average transmission power and bandwidth efficiency are analyzed. On the meantime, the slot error rate is also analyzed on the given model.
