    The goals of hypervisor design include:

    1. Resource Management: Efficiently allocate and manage hardware resources (CPU, memory, storage, and network) among multiple virtual machines (VMs) while ensuring that each VM performs optimally.

    2. Isolation: Ensure that each VM operates independently, preventing one VM from interfering with the operation or security of another. This includes managing fault and security isolation.

    3. Performance: Minimize the overhead introduced by virtualization to ensure that VMs have performance characteristics as close to bare-metal as possible.

    4. Scalability: Support the deployment and dynamic scaling of VMs in response to varying workloads and demands without degradation of performance.

    5. Security: Provide robust security measures to protect the hypervisor and VMs from attacks, including secure VM creation, migration, and termination processes.

    6. Compatibility and Portability: Ensure that the hypervisor can work with a wide range of operating systems and applications, allowing for easy migration and deployment of VMs across different environments.

    7. Manageability: Offer tools and interfaces for easy monitoring, managing, and configuring the virtualized environment, including automated management capabilities.

    8. High Availability: Implement features for fault tolerance and failover to maintain uptime of services even in the event of hardware failures.

    9. Support for Multiple Virtualization Techniques: Provide support for various virtualization models such as full virtualization, para-virtualization, and hardware-assisted virtualization

    There are several methods to move data through a network of links and switches:

    1. Packet Switching: Data is broken into small packets, each of which is sent independently through the network. Routers direct these packets based on the most efficient path.

    2. Circuit Switching: A dedicated communication path (circuit) is established between the sender and receiver for the duration of the communication session.

    3. Frame Relay: This is a packet-switching protocol that operates at the data link layer and is used for connecting devices on a Wide Area Network (WAN). It uses a variable-sized packet (frame) for data transmission.

    4. Asynchronous Transfer Mode (ATM): A high-speed networking standard that uses fixed-size cells for data transfer. It is efficient for high-bandwidth applications like voice, video, and data.

    5. Multiprotocol Label Switching (MPLS): This technique improves the speed and control of packet forwarding by assigning labels to packets, which allows routers to make forwarding decisions without examining the packet’s destination address each time.

    6. Ethernet Switching: In local area networks (LANs), Ethernet switches direct data frames to specific devices based on MAC addresses, ensuring they reach the correct destination.

    7. Virtual LANs (VLANs): VLANs allow a single physical network to be partitioned into multiple logical networks, enabling more efficient data handling and improved security.
