“…So far, a number of solutions regarding failure recovery in SDN have already been proposed . Among these mechanisms, 7 mechanisms are protection failure recovery mechanisms [13][14][15][16][17][18][19]. Fourteen mechanisms are restoration failure recovery mechanisms [20][21][22][23][24][25][26][27][28][29][30][31][32][33].…”

“…For the protection failure recovery mechanisms [13][14][15][16][17][18][19], the recovery path will be selected in advance. No matter where the recovery path is stored, after the failure is detected, the recovery path will be used to replace the faulty path.…”

REVERT: A Network Failure Recovery Method for Data Center Networks

As a repository that holds computing facilities, storage facilities, network facilities and other facilities, the Software Defined Data Center (SDDC) can provide computing and storage resources for users. For a SDDC, it is important to provide continuous services for users. Hence, in order to achieve high reliability in Software Defined Data Center Networks (SDDCNs), a network failure recovery method for software defined data center networks (REVERT) is proposed to recover failures in SDDCNs. In REVERT, the network failures that occurred in SDDCNs are classified into three types, which are switch failure, failure of links among switches and failure of links between switches and servers. Specially, except recovering the switch failure and failure of links between switches, REVERT can also recover the failures of links between the switches and servers. To achieve that, a failure preprocessing method used to classify the network failures, a data structure for storing and finding the affected flows, a server cluster agent for communicating with the server clustering algorithm and a routing path calculation method are designed in REVERT. Meanwhile, REVERT has been implemented and evaluated on RYU controller and Mininet using three routing algorithms. Compared with the link usage before recovering the network failures, when there are more than 200 flows in the network, the mean link usages only slightly increase at about 1.83 percent. More importantly, the evaluation results also demonstrate that except recovering switch failures, intra-topo link failures, REVERT has the ability of recovering failures of links between servers and edge switches successfully.

“…In the case of protection, rerouting is almost immediate, but then minimizing the number of table entries is crucial. Feng et al [12] provide an algorithm for this purpose. Hu et al [13] investigate protection with multiple controllers and propose a scheme based on local rerouting and reverse forwarding.…”

Amaru: Plug&Play Resilient In-Band Control for SDN

et al. 2019

View full text Add to dashboard Cite

Software-Defined Networking (SDN) is a pillar of next-generation networks. Implementing SDN requires the establishment of a decoupled control communication, which might be installed either as an out-of-band or in-band network. While the benefits of in-band control networks seem apparent, no standard protocol exists and most of setups are based on ad-hoc solutions. This article defines Amaru, a protocol that provides plug&play resilient in-band control for SDN with low-complexity and high scalability. Amaru follows an exploration mechanism to find all possible paths between the controller and any node of the network, which drastically reduces convergence time and exchanged messages, while increasing robustness. Routing is based on masked MAC addresses, which also simplifies routing tables, minimizing the number of entries to one per path, independently of the network size. We evaluated Amaru with three different implementations and diverse types of networks and failures, and obtained excellent results, providing almost on-the-fly rerouting and low recovery time.

“…On the other hand, the passive strategy reactively adjusts routing decisions when link failure occurs, while the active strategy pre-deploys backup resources in the network. For example, the shared ring method is proposed in [12] to reuse backup resources, aiming to cost effectively pre-deploying backup resources in TCAM. Although both recovery delay and the TCAM usage could be improved, the congestion may occurs in the post-recovery network.…”

Due to the rapid development of IoT technology, automatic guided vehicles (AGVs) interact with an industrial control system (ICS) through the wireless network to support the freight distribution in the automated warehouse. However, the message exchange among AGVs and the ICS would experience large packet loss or long transmission delay, in the presence of wireless network link failure and link congestion. Therefore, the performance of warehouse automation would be degraded. In this paper, we propose the Software Defined Fast Failure Recovery (SD-FFR) mechanism, aiming to improve network reliability and avoid link congestion caused by load unbalance. With SD-FFR, when link failure occurs, the SDN controller actively detects the link failure within milliseconds, and then reroutes the affected traffic flows accordingly. The proposed SD-FFR mechanism also takes load balance into consideration in selecting routing paths when a new traffic flow joins or link failure occurs in the network. The evaluation results show that network performance can be time efficiently improved.
