- Brush up on option statements in VB.NET
- In this tip, Irina Medvinskaya looks at the three option statements that are supported in VB.NET: Option Explicit, Option Compare, and Option Strict. If you want to properly utilize VB.NET, it is very important to understand option statements. The following is a quick overview of the three ...

- Use these ASP scripting techniques
- By Amy Cowen(6/29/99)In VBScript, you don't have to declare variables or explicitly define their type the way you do in other scripting languages. A variable exists the first time you use it. This feature leaves your code wide-open to typos, however. If you mistype a variable name somewhere in the...

- Avoid program bugs in VB6 with the Option Explicit statement
- In Visual Basic 6, you can use a variable in code without declaring it. Some VB programmers tout this as an advantage of VB, but, in fact, it's a serious shortcoming. Peter Aitken explains why. Most programming languages, such as C and Fortran, require that you explicitly...

- Provable Implementations of Security Protocols
- Protocols such as those developed here are prone to extremely subtle errors that are unlikely to be detected in normal operation. The need for techniques to verify the correctness of such protocols is great, and it encourages those interested in such problems to consider this area. Robust security is about...

- Explicit Mechanisms for Controlling NAT/Firewall Systems Dynamically
- NAT/Firewall systems are very widely utilized in today's network environments, such as intranets and the Internet. Together with many security enhancements, however, the use of NATs/Firewalls has raised a number of new issues and problems. Most of them related to the complex NAT/Firewall traversal problem, where applications and services are...

- Convert tacit knowledge into explicit knowledge to ensure better application development
- Anyone who's ever developed an application from scratch knows that it's difficult to fully understand the objective of the user or subject matter expert, when they describe the problem that the code is supposed to solve. We can clearly define the characteristic behaviors that must be present for good software...

- RATES: A Server for MPLS Traffic Engineering
- It has been suggested that one of the most significant reasons for Multi-Protocol Label Switched MPLS network deployment is network traffic engineering. The goal of traffic engineering is to make best use of the network infrastructure and this is facilitated by the explicit routing feature of MPLS which allows the...

- Intel Threading Tools and OpenMP
- Explicit threading methods, such as Windows threads or POSIX threads, use library calls to create, manage, and synchronize threads. Use of explicit threads requires an almost complete restructuring of affected code. On the other hand, OpenMP is a set of pragmas, API functions, and environment variables that enable one to...

- TCP MaxNet - Implementation and Experiments on the WAN in Lab
- This paper describes implementation and performance of TCP MaxNet, a new protocol which uses a multi-bit explicit signaling approach to congestion control. The MaxNet sender algorithm operates by adjusting its congestion window in response to explicit feedback from the most congested link encountered in the network. This scheme has numerous...

- Source Selectable Path Diversity Via Routing Deflections
- This paper presents the design of a routing system in which end-systems set tags to select non-shortest path routes as an alternative to explicit source routes. Routers collectively generate these routes by using tags as hints to independently deflect packets to neighbors that lie off the shortest-path. It show how...

- Explicit Congestion Notification (ECN) for TCP/IP
- When routers become congested to the point in which their incoming packet buffers fill and they begin dropping packets, the effect on the network is reduced bandwidth, an impact on loss or time-sensitive traffic flows, and possibly link idle time after the congestion occurs. Explicit Congestion Notification ECN for TCP/IP...
