Assessment Example Consider a WDM node with 4 directions and 160? per fiber Wavelength configuration information per fiber: (4-byte lambda label as defined by lambda label draft) 160 * 4 = 640 bytes (static information) Potential Wavelength Connectivity Information (one bit for each ?’s connectivity to each ? on each other fiber) 3 X 160 X 160 / 8 = 38400 bytes (semi-static) Add/Drop Availability (one bit for each ?) 160 / 8 = 20 bytes (semi-static) Wavelength availability status information per fiber: (one bit represents the status of each ?) 160 / 8 = 20 bytes (dynamic) |
