- How the IP Multicast Router Works
- Multicasting allows a host to transmit an IP datagram to a set of hosts that form a multicast group. Every member in a multicast group that uses the same multicast address can receive a copy of the IP datagram. Multicast routers are responsible for delivering and copying datagrams to those...

- Using datagrams in Java
- The User Datagram Protocol UDP allows an application to send data in packets with a low overhead and is employed in some important standards, like DNS and RADIUS. Many programmers may not be familiar with the protocol, though, since it is harder to program and less frequently used than TCP....

- Lock IT Down: Are you under a denial of service attack?
- Analyze whether your network is under a denial of service attackIn an earlier article, I discussed the fundamentals of datagram fragmentation and explained how it can affect the speed of your network. I also mentioned the vulnerabilities all networks have to malicious fragments. In this article, I will go more...

- Avoiding the IP Fragmentation Process at the Application Layer of the OSI Reference Model
- The modern recommendations regarding the IP fragmentation process is to avoid it. There are different possibilities regarding the OSI model layers to implement logic for avoiding fragmentation. The present study describes some considerations about implementing the IP fragmentation avoiding at the Application Layer. The fragmentation and reassembly function ensures compatibility...

- Why should you worry about datagram fragmentation?
- If your firewall appears to be swamped, the problem may be datagram fragmentation. Find out more in this latest Locksmith article.Packet filtering seems simple enough on the surface, but unless you understand what is happening inside the router or firewall, you may miss a gigantic hole in your perimeter defenses....

- Towards a Framework for Network Control Composition
- IP networks nowadays perform many functions in addition to best-effort datagram forwarding. These functions are typically achieved via an ad hoc combination of distributed protocols, database- and tool-driven router configurations, and manual configurations. In such an ad hoc system, it is difficult to anticipate any potential harmful interactions among the...

- MSDN Webcast: Working With Operations and Calls in Windows Communication Foundation (Level 200)
- Windows Communication Foundation provides the user with several message-exchange patterns for dispatching calls to the service: request/reply, one-way datagram, duplex, or data streaming. This webcast describes each of these dispatch types, and offer insight and examples that illustrate when and where each pattern is most appropriate and explains how the...

- sMonitor (zip)
- sMonitor is a network monitoring software that allows you to verify the network connectivity of TCP/IP hosts on the Internet and LAN. The built-in NT service periodically pings, or checks TCP and UDP ports on network devices. If the destination host fails to reply to a ping, connection request, or...

- An Evaluation Framework for the Analysis of Covert Channels in the TCP/IP Protocol Suite
- Information hiding techniques can be used by criminals and terrorists to communicate over covert channels within the TCP/IP protocol suite and can be used to overcome firewalls and most other forms of network intrusion detection and prevention systems. The work described in this paper is the covert channel concept and...

- TCP Streaming for Low-Delay Wireless Video
- With the penetration and popularity of mobile devices such as pocket PCs and smart-phones, there is an increasing need of low-delay video streaming over wireless channel. Traditionally, UDP User Datagram Protocol is used for video streaming. However, due to unreliable transmission and fluctuating bandwidth of wireless channel, this requires error...

- A New Prioritized Fast Handoff Protocol for Mobile IP
- Mobile IP protocol has been designed to handle global and seamless user's mobility on the Internet. However, Mobile IP suffers from handoff latency due to slow handoff discovery and binding association notification. To reduce this latency, the paper proposes a new handoff protocol where it attributes a high priority to...
