- Autonomous Services and Enterprise Entity Aggregation
- Enterprises depend on heterogeneous systems and applications to function. Each of these systems manages its own data and often doesn't explicitly expose it for external consumption. Many of these systems depend on the same basic concepts like customer and employee and, as a result, these entities have been defined in...

- ADO.NET Tech Preview: Entity Data Model
- The Entity Data Model is an Entity-Relationship data model. The ER model is familiar to most if not all database application developers, and has been used successfully for about 30 years. The central concepts in the EDM are entities and relationships. Entities are instances of Entity Types (e.g., Customer, Employee)...

- Performance Analysis of Data Aggregation Techniques for Wireless LAN
- Data aggregation is a mechanism in which multiple packets are transmitted to a receiver, followed by a single acknowledgment. As opposed to typical explicit-acknowledgment schemes, aggregation schemes benefit from amortizing the control overhead over multiple packets. The achievable benefit from data aggregation is often of interest, especially in the face...

- Converting an EJB 2.0 Entity Bean to EJB 3.0
- The Enterprise JavaBeans EJB 3.0 specification has facilitated the development of EJBs, by providing an annotations-based API in which the remote/local and home/local home interfaces are not required. The deployment descriptors that form the basis of an EJB 2.0 entity bean are also not required for deploying an EJB 3...

- Extended Persistence Context in Stateful Session Beans
- The Java Persistence Architecture, a part of the Enterprise JavaBeans 3.0 (EJB 3.0) specification, simplified the development of EJB applications using data persistence. A major simplification was the introduction of the EntityManager interface for accessing a database and creating, removing, or updating entities within a transaction. Entities are objects that...

- Appreciating the Entity Object
- An Oracle Application Development Framework ADF entity object represents a business domain entity such as an order, a part, a customer, or a service request. By creating a set of associated Oracle ADF entity objects that represents the full business domain model inside the J2EE applications, one can significantly boost...

- HP Auto Port Aggregation: Performance and Scalability White Paper
- HP Auto Port Aggregation is a software product that creates link aggregates, often called "Trunks," which provide a logical grouping of two or more physical ports into a single "Fat Pipe." Two primary features are automatic link failure detection and recovery as well as support for load balancing of network...

- The ADO.NET Entity Framework: Making the Conceptual Level Real
- This paper describes the ADO.NET Entity Framework, a platform for programming against data that raises the level of abstraction from the logical relational level to the conceptual entity level, and thereby significantly reduces the impedance mismatch for applications and data services such as reporting, analysis, and replication. The conceptual data...

- Address Aggregation in Mobile Ad Hoc Networks
- Current Mobile Ad hoc NETwork MANET routing protocols operate with networks as flat address spaces, treating all nodes in the network as independent peers. However, these nodes are not always independent; they can form groups due to physical or environmental restraints. By taking advantage of these natural groupings, there is...

- Multicast Traffic Aggregation in MPLS-Based VPN Networks
- This paper gives an overview of the current practical approaches under study for a scalable implementation of multicast in Layer 2 and Layer 3 VPNs over an IP-MPLS multiservice network. These proposals are based on a well-known technique: the aggregation of traffic into shared trees to manage the forwarding-state vs...

- On the Number of MPLS LSPs Using Multicast Tree Aggregation
- Multicast tree aggregation is an efficient proposition that can solve the multicast forwarding state scalability problem. Existing works on tree aggregation have focused on developing and simulating protocols that build trees dynamically. However, the underlying problem of the impact of the tree construction algorithm on the performance of the protocols...

- A Firm Foundation-Migrating the Cisco WAN to the Cisco 7600 Router Platform
- Cisco's business foundation-a WAN across North America-reflected the evolution of Cisco technology and product development, but it could no longer support the growing bandwidth demands resulting from Cisco's astronomical growth and several new, real-time peer-to-peer applications that multiplied traffic across the WAN. For Cisco, the solution foundation turned out to...

- Modeling Traffic-Engineering VPN Aggregation in GMPLS-Based VPN Networks
- This paper gives an overview of the current approaches under standardization for the implementation of scalable multicast VPN service over an IP-MPLS multiservice network. These techniques are based on the aggregation of traffic with different granularities to deal with the state vs bandwidth trade-off. A simple method to explore this...
