To achieve fast recovery of optical transport networks after a disaster, we investigate a novel scheme enabling cooperation between carriers. Carriers can take advantage of their surviving or recovered optical resources to aid each other through an emergency lightpath support, thereby efficiently reducing the recovery burden, which can be heavy immediately after a disaster. Such lightpaths can be exclusively employed by counterpart carriers to satisfy their highest-priority traffic demands, such as safety confirmation and victim relief. In addition, we introduce an incentive to carriers to promote such cooperation. The carrier cooperation-planning problem is divided into eight tasks and distributed to the individual carriers and a third-party organization. During cooperation, confidential carrier information can be strictly protected by employing a carrier optical network abstraction mechanism. The evaluation results indicate that our proposed approach can significantly reduce the recovery burden and corresponding cost to carriers, resulting in a faster and more efficient disaster recovery.

一种新颖的运营商合作计划,旨在在灾难恢复期间提供紧急光路支持
为了在灾难后实现光传输网络的快速恢复,我们研究了一种使运营商之间能够合作的新颖方案。运营商可以利用幸存或恢复的光资源,通过紧急光路支持互相帮助,从而有效地减少了恢复负担,这在灾难发生后会很重。此类光路可以由对方承运人专门使用,以满足其最高优先级的交通需求,例如安全确认和受害者救助。此外,我们还向运营商引入激励措施以促进这种合作。运营商合作计划问题分为八个任务,并分配给各个运营商和第三方组织。合作期间 通过采用运营商光网络抽象机制,可以严格保护机密的运营商信息。评估结果表明,我们提出的方法可以显着减少运营商的恢复负担和相应成本,从而实现更快,更有效的灾难恢复。
