Kertas kerja ini mencadangkan Nod Teras Fotonik berdasarkan fabrik pensuisan opto-elektronik 2.56-Terabit/s, yang boleh mengendalikan trafik multimedia yang semakin meningkat secara ekonomi, seperti trafik Internet. Kami telah berjaya membangunkan prototaip pertama Nod Teras Fotonik. Prototaip ini terdiri daripada fabrik pensuisan opto-elektronik bar silang penuh satu peringkat, penimbal paket super untuk baris gilir input dan penjadual pusingan yang tidak segerak. Fabrik pensuisan boleh dinaik taraf sehingga 2.56 Tb/s, dan menggunakan teknik pemultipleksan pembahagian panjang gelombang, yang secara mendadak mengurangkan jumlah elemen pensuisan optik kepada satu perlapan bilangan yang digunakan dalam fabrik pensuisan konvensional. Penimbal paket super memasang 16 sel ATM yang dihalakan ke port keluaran yang sama ke dalam satu paket panjang tetap. Skim pensuisan paket super secara drastik mengurangkan overhed pensuisan optik daripada 32 kepada 2.9%, walaupun ia cenderung mengurangkan daya pengeluaran yang berkesan. Penjadual round-robin yang tidak segerak mengekalkan daya pemprosesan yang hampir 100% berkesan untuk trafik rawak, secara rekursif menyelesaikan pertikaian permintaan sambungan dalam satu rutin penjadualan sambil mengekalkan keadilan secara round robin. Nod Teras Fotonik yang dicadangkan boleh menampung bukan sahaja pensuisan ATM tetapi juga dandanan/multipleks laluan optik WDM, dan penghalaan IP dengan menggunakan antara muka penimbal input IP, kerana suis optik adalah kadar bit/bebas format.

Abstract: This paper proposes Photonic Core Node based on a 2.56-Terabit/s opto-electronic switching fabric, which can economically handle the rapidly increasing multimedia traffics, such as Internet traffic. We have successfully developed the first prototype of Photonic Core Node. The prototype consists of a single-stage full-crossbar opto-electronic switching fabric, super-packet buffers for input queuing, and a desynchronized-round-robin scheduler. The switching fabric is upgradable up to 2.56 Tb/s, and employs wavelength-division-multiplexing techniques, which dramatically reduce the total number of optical switching elements down to one-eighth the number of those used in a conventional switching fabric. The super-packet buffer assembles 16 ATM cells routed to the same output port into a single fixed-length packet. The super-packet-switching scheme drastically reduces the overhead of optical switching from 32 to 2.9%, although it tends to decrease effective throughput. The desynchronized-round-robin scheduler maintains nearly 100% effective throughput for random traffic, recursively resolving the contention of connection requests in one scheduling routine while keeping fairness in a round robin manner. The proposed Photonic Core Node can accommodate not only ATM switching but also WDM optical path grooming/multiplexing, and IP routing by using IP input buffer interfaces, because optical switches are bit-rate/format-independent.
