提出了一种基于多个光正交码序列（MOOCS）的光分组交换（OPS）网络全光标签处理方案（MOOCS-OPS）。在该方案中，每个MOOCS是从多组光正交码（MGOOC）中选择的多个光正交码（MOOC）的排列或组合。在比较了不同的光标签处理（OLP）方案的基础上，给出并分析了MOOCS-OPS网络的工作原理。首先，通过理论分析证明了MOOCS与以前的单光正交码（SOOC）OPS（SOOC-OPS）网络相比，能够大大增加可用光标签的数量。然后，详细介绍了基于MOOCS的光标签包的关键单元，包括光包生成、光标签擦除、光标签提取和光标签重写等，被给予和研究。这些结果被用来验证所提出的MOOCS-OPS方案是可行的。
This paper proposes an all-optical label processing scheme that uses the multiple optical orthogonal codes sequences (MOOCS)-based optical label for optical packet switching (OPS) (MOOCS–OPS) networks. In this scheme, each MOOCS is a permutation or combination of the multiple optical orthogonal codes (MOOC) selected from the multiple-groups optical orthogonal codes (MGOOC). Following a comparison of different optical label processing (OLP) schemes, the principles of MOOCS–OPS network are given and analyzed. Firstly, theoretical analyses are used to prove that MOOCS is able to greatly enlarge the number of available optical labels when compared to the previous single optical orthogonal code (SOOC) for OPS (SOOC–OPS) network. Then, the key units of the MOOCS-based optical label packets, including optical packet generation, optical label erasing, optical label extraction and optical label rewriting etc., are given and studied. These results are used to verify that the proposed MOOCS–OPS scheme is feasible.
