Dengan mengguna pakai seni bina rangkaian di mana bukan sahaja panggilan tetapi juga terminal dipanggil boleh memilih panjang gelombang, rangkaian WDM baru menjadi mungkin. Ini kami panggil Rangkaian Fotonik Tugasan Panjang Gelombang (WAPN). Dalam rangkaian ini, panjang gelombang adalah sejenis sumber rangkaian dan mengikut permintaan daripada terminal, panjang gelombang diperuntukkan atau diberikan kepada panggilan. Dalam sistem, panjang gelombang yang digunakan untuk panggilan akan digunakan untuk panggilan lain selepas panggilan ditamatkan. Dengan membekalkan panjang gelombang ke rumah, rangkaian bebas bitrate, bebas protokol atau malah kaedah penghantaran bebas boleh direalisasikan. Dalam kertas ini, dari sudut pandangan faktor S/N atau Q, WAPN dinilai dengan tumpuan khusus pada seni bina nod--iaitu, dari sudut pandangan saiz nod, bilangan peringkat penukaran, tahap crosstalk dan kerugian, kerana yang dibenarkan saiz nod adalah isu penting untuk menentukan kapasiti keseluruhan rangkaian. Selepas penerangan ringkas tentang sistem yang dicadangkan ini, model untuk penilaian sistem akan diwujudkan dan sistem nod akan dinilai untuk beberapa nilai parameter praktikal dengan mengambil kira ciri-ciri trafik sesuatu nod. Hasil daripada kajian ini sistem nod dengan kapasiti lebih daripada 100 ribu erl (kira-kira 20 Tbps throughput) boleh dibina menggunakan teknologi sedia ada, yang akan membolehkan kami membina rangkaian WAPN yang besar dengan radius 2,000 km dan pelanggan kira-kira 50 juta .

Abstract: By adopting a network architecture in which not only a calling but also a called terminal can select a wavelength, a novel WDM network becomes possible. This we call Wavelength Assignment Photonic Network (WAPN). In this network wavelengths are a kind of network resources and according to requests from terminals, wavelengths are allocated or assigned to calls. In the system a wavelength used for a call is to be used for another call after the call is terminated. By supplying wavelengths to the home, a bitrate-free, protocol free or even transmission method free network can be realized. In this paper, from a viewpoint of S/N or Q factor, WAPN is evaluated with special focus on the node architecture--i. e. , from the viewpoint of node size, number of switching stages, crosstalk level,and losses, because the allowable node size is the crucial issue to decide the whole network capacity. After brief explanations of this proposed system, the model for system evaluations will be established and a node system is to be evaluated for some practical parameter values considering especially traffic characteristics of a node. As a result of this study a node system with capacity more than 100 thousands erl (about 20 Tbps throughput) can be constructed using present available technologies, which will enable us to construct large WAPN network with radius of 2,000 km and subscribers of about 50 millions.
