Abstract:	摘要： Software-defined networks (SDNs) provide flexibility for developing new network protocols and policies in real networks. The SDN controller translates network policies into specific rules in the flow tables [which are usually implemented using ternary content addressable memory (TCAM)] of each network switch. However, due to the limitation of TCAM (e.g., high power consumption and high heat generation), the flow tables cannot scale beyond a few hundred entries. Hence, the switches usually reactively cache rules (i.e., installing rules on demand). However, the reactively caching rules causes packet delay and large buffers, when cache misses happen. To improve the performance, in this paper, we propose a rule partition and allocation algorithm to distribute the rules across network switches. Our algorithm not only is applicable to small TCAM switch scenario but also guarantees semantically invariant (i.e., the global action of the network is unchanged). 其他題名： TETC 出版者： IEEE 出版日期： 2016-04 出處： IEEE transactions on emerging topics in computing, 2016-04, Vol.4 (2), p.252-261 資源來源： IEEE Electronic Library (IEL) 識別號： ISSN: 2168-6750 識別號： EISSN: 2168-6750 識別號： DOI: 10.1109/TETC.2015.2457333 識別號： CODEN: ITETBT
