A load-balancing spare capacity reallocation approach in service-rich SONET metro mesh networks

The next-generation SONET metro network is evolving into a service-rich infrastructure. At the edge of such a network, multi-service provisioning platforms (MSPPs) provide efficient data mapping enabled by Generic Framing Procedure (GFP) and Virtual Concatenation (VC). The core of the network tends to be a meshed architecture equipped with Multi-Service Switches (MSSs). In the context of these emerging technologies, we propose a load-balancing spare capacity reallocation approach to improve network utilization in the next-generation SONET metro networks. Using our approach, carriers can postpone network upgrades, resulting in increased revenue with reduced capital expenditures (CAPEX). For the first time, we consider the spare capacity reallocation problem from a capacity upgrade and network planning perspective. Our approach can operate in the context of shared-path protection (with backup multiplexing) because it reallocates spare capacity without disrupting working services. Unlike previous spare capacity reallocation approaches which aim at minimizing total spare capacity, our load-balancing approach minimizes the network load vector (NLV), which is a novel metric that reflects the network load distribution. Because NLV takes into consideration both uniform and non-uniform link capacity distribution, our approach can benefit both uniform and non-uniform networks. We develop a greedy loadbalancing spare capacity reallocation (GLB-SCR) heuristic algorithm to implement this approach. Our experimental results show that GLB-SCR outperforms a previously proposed algorithm (SSR) in terms of established connection capacity and total network capacity in both uniform and non-uniform networks.

RP93-395 Liability Insurance and the Family Child Care Provider

Life other small business owners, family child care providers need adequate life, health, and disability insurance to protect their families from the loss of their income. However, child care providers also face unique risks. Perhaps the most important of these risks is the financial loss that would result if the provider were found liable or responsible for the injury or death of a child or a child's parent. If a claim were filed against you as a provider, three different types of financial losses are possible: medical expenses, damages awarded to the victim or his/her family after a lawsuit, and court costs related to your defense. This booklet will help you to: (1) evaluate options for insuring a family child care operation, and (2) evaluate available liability insurance policies.

Termination of Desegregation Decrees and the Elusive Meaning of Unitary Status

Discusses the termination of desegregation decrees and the elusive meaning of unitary status, first introducing the topic and then covering Jenkins III and providing an overview of desegregation scholarship including discretion, capacity, and legitima. Also discusses the evolution of equity, including English equity, American equity, and equity and desegregation. Explores the concepts of relevant rights and interests, focusing on Hohfeld, the interest theory of rights, and the application of the rights theory. The conclusion posits that what remains is a complicated and confused desegregation jurisprudence, and that the lines that separate desegregation from integration from diversity, if there ever were such lines, are blurring. A discussion of the theoretical premises underlying desegregation appears to continue to be necessary.
