Key Concepts
- Multimedia applications, both traditional and advanced, need appropriate communication architectures, networks, and protocols, to bridge physical distances, meet application demands, and for successful operation.
- Specific multimedia protocols like ATM and protocols for managing quality of service (QoS) also play a significant role in efficiently and effectively transferring multimedia data.
- Challenges associated with multimedia communication include issues relating to resource allocation, efficient bandwidth usage, and addressing the need for real-time delivery.
- QoS parameters, such as delay, jitter, bandwidth, loss, and availability, determine the quality of the communication experience.
- Various mechanisms, like traffic shaping and congestion control, ensure consistent and reliable data transfer. Different transmission media, like optical fiber, play critical roles in high-speed networking, impacting performance.
- The protocols for these systems are managed via a network control plane.
- Operation and Management of networks is addressed in layers and components.
- Network devices, such as switches, routers, and multiplexers, play a crucial role.
- Software-defined networking (SDN) offers a more flexible and programmable approach to network management, potentially increasing performance.
- Message brokers and VPNs are important protocols for communication with other systems.
- Understanding these components and characteristics is vital for the design, implementation, and success of multimedia communication systems.
