When the packets arrive in a switch, the switch decrements the current TTL value in the packet before forwarding it by the instructions of the flow table, and the packet could not forward to other switches when TTL comes to 0 or it arrives at the destination. Then, we send 100 packets on PC_01 to PC_02 and use the Wireshark to capture the packets on the switches in the link. In Table 2, we compare two situations of whether running this component. It could easily ﬁnd that the number of the packets is many times than without running this module.
In this work, we present POFOX, a SDN controller for POF. Unlike the Huawei controller, POFOX is highly flexible and enables users to manage the POF devices with Python programs. In the design and implementation of POFOX, we have borrowed the programming model and the basic architecture of POX , a very popular OpenFlow controller, and re-design and re-code the key components of the controller such as the communication engine and the topology discovery component to support the POF devices. We have also constructed the ﬁrst programmable POF network testbed with POFOX, and examine the network’s performance with real-world experiments.
1 Dataset The data source we choosed in the experiment is Douban dataset. More specially, most friends on Douban actually know each other offline and the friendship is symmetrically. It is an ideal source for our research on social recommendation. The dataset contains three aspects: music, book, and movie. In the paper, we randomly select 80 % of the ratings to train the models. 36 Z. Zhang and H. Shen Table 1 Statistics of friend relationship and shared friends Statistics Music Book Movie Max.
