Abstract:
1. A method for transmitting a packet in a wireless access network based on a wavelength identification code scheme, comprising the steps of: a) connecting n number of RNCs (Radio Network Controllers) to one sub-ring where the “n” is a positive integer, and assigning a unique wavelength to each RNC; b) transmitting a packet from one RNC to another RNC via a SRC (Sub-Ring Controller) of the sub-ring by distinguishing the packet using the assigned unique wavelengths within the sub-ring; c) connecting m number of SRCs to one main-ring where the “m” is a positive integer, and assigning a unique wavelength to each SRC; and d) encapsulating a wavelength identification code in a packet to be transmitted between the RNCs located within different sub-rings, and routing the packet having the encapsulated wavelength identification code through an MRC (Main-Ring Controller).
