Hello, we want to make you aware of a new I-D named Priority based Flow Rule Request Message Processing Mechanism in the OpenFlow Switch. The interesting part of this document for SDNRG is probably the processing order of the control messages within a transaction between the controller and the OpenFlow switch. This document proposes the combination of appending the priority attribute to the packet-in message and the PFRRMPM as one solution to this problem. On the other hand, we want to have more people to recognize and highlight the similar problem so as to extend and generalize it to the other aspects in the Control Plane Southbound Interface(or the SDN) instead of being specific to the OpenFlow. We are eager to hear your comments, criticisms, and questions. Best regards, Xinjian Long ---------- Forwarded message ---------- From: <internet-drafts@ietf.org> Date: 2016-04-05 22:15 GMT+08:00 Subject: New Version Notification for draft-long-sdnrg-pfrrmpm-openflow-00.txt To: Xinjian Long <xjlong19921117@gmail.com>, Xiangyang Gong < xygong@bupt.edu.cn>, Xirong Que <rongqx@bupt.edu.cn>, Wendong Wang < wdwang@bupt.edu.cn>, Qinglei Qi <qiqinglei1984@126.com> A new version of I-D, draft-long-sdnrg-pfrrmpm-openflow-00.txt has been successfully submitted by Xinjian Long and posted to the IETF repository. Name: draft-long-sdnrg-pfrrmpm-openflow Revision: 00 Title: Priority based Flow Rule Request Message Processing Mechanism in the OpenFlow Switch Document date: 2016-04-04 Group: Individual Submission Pages: 13 URL: https://www.ietf.org/internet-drafts/draft-long-sdnrg-pfrrmpm-openflow-00.txt Status: https://datatracker.ietf.org/doc/draft-long-sdnrg-pfrrmpm-openflow/ Htmlized: https://tools.ietf.org/html/draft-long-sdnrg-pfrrmpm-openflow-00 Abstract: In the SDN, the controller is in charge of the maintenance and administration of variable aspects like the network topology and the network resources etc. of the whole network. Administrative strategies are made upon these work and sent to the switches from the controller so as to instruct the network devices to apply appropriate policies to the data flows. As for the data packet which reaches the ingress OpenFlow switch for the first time, the packet itself or a fraction of the packet will be encapsulated into a packet-in message and will be sent to the controller to request for a new flow rule. After the flow-mod message and the packet-out message are sent back to the switch from the controller, the determined forwarding action will be applied to the certain data flow. So far, the inbound latency caused by the creation of the packet-in message and the outbound latency caused by the receive and the execution of the flow-mod message are highlighted when it comes to the concerns about the latency and the effectiveness of the data transportation in the SDN[Mazu]. Attention to the studies on the processing order of the flow rule request message like the packet-in message and the packet-out message is comparatively low. As the SDN continually grows in scale and complexity and the packets' forwarding policies become more recursive and dynamic, the number of the switches under the administration of the same controller is elevated and unavoidably causes the network congestion problem widespread. The scale of modern networks and data-centers and the associated operational expense deteriorates the delay problem in the network with congestion. The ability to help the services with high priority be processed without delay becomes critical. This document proposes the combination of appending a priority tag to the packet-in message and the Priority based Flow Rule Request Message Processing Mechanism(PFRRMPM) as a solution to help the data flow with high priority or lantency-sensitive to acquire the forwarding rule without or with shorter waiting latency when there are excess flow rule request messages in the SDN. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
