Summary
This study presents a new ingress node design for optical burst switching networks that improves video streaming quality using H.264/AVC. The novel scheme enhances video quality without impacting other network traffic.
Area of Science:
- Computer Science
- Telecommunications Engineering

Background:
- Optical burst switching (OBS) networks are crucial for high-speed data transmission.
- Ensuring quality of service for video streaming over OBS networks presents challenges.
- Existing methods like burst cloning have limitations in optimizing video quality.
Purpose of the Study:
- To propose a novel ingress node design for OBS networks.
- To enhance video streaming quality using the H.264/AVC codec.
- To evaluate the performance of the proposed design through simulations.
Main Methods:
- A new ingress node design leveraging video data partitioning.
- Implementation of the design in Ns2 network simulator.
- Comparison with existing burst cloning schemes.
Main Results:
- The proposed scheme significantly improves video traffic quality.
- Achieved an average gain of 5 dB in video Peak Signal-to-Noise Ratio (PSNR).
- Maintained low end-to-end delay (max 17 ms) and jitter (less than 0.35 ms).
- No adverse impact on best-effort traffic was observed.
Conclusions:
- The novel ingress node design effectively enhances video streaming quality in OBS networks.
- Video data partitioning is a viable strategy for quality improvement.
- The scheme offers a good balance between video quality enhancement and network overhead.

01:23Transmission Line Design Considerations
Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...
01:24Cable Subjected to a Distributed Load
The analysis of suspension bridges is a complex and critical process that involves multiple factors, including the shape and tension of the main cables. The main cables of suspension bridges are subjected to distributed loads, which result in changes in tensile forces and deformation of the cable. These loads must be carefully considered to ensure that the bridge is safe and capable of supporting the weight of different loads.
01:11IP3/DAG Signaling Pathway
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
01:27Design Example: Design of an Irrigation Channel
Trapezoidal channels are widely used in irrigation systems due to their cost-effectiveness and efficiency in conveying water. Trapezoidal channels feature a flat bottom and sloping sides, making them stable and easier to construct compared to other shapes. The bottom width and side slope ratio are determined based on the required flow capacity and site conditions. The side slope is kept gentle for unlined channels to prevent soil erosion.Hydraulic parameters in channel design include the flow...
01:25Network Function of a Circuit
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.
01:27Uniform Depth Channel Flow
Uniform depth channel flow keeps fluid depth consistent along channels such as irrigation canals. In natural channels, such as rivers, approximate uniform flow is often assumed. This condition occurs when the channel’s bottom slope matches the energy slope, balancing potential energy lost from gravity with head loss due to shear stress. This balance prevents depth changes along the channel length, resulting in a steady, uniform flow.Uniform flow in open channels with a constant cross-section...
