Virtual Switch is a software program which allows communication between two virtual machines. A vSwitch, as what it is commonly called, can do more than just forwarding packets of data. It can smartly direct the communication on a network by reviewing data packets before moving them to their specified destination. This hands-free advancement has already dominated the world of trade and commerce because of its versatility. Various online service companies such as Conmutadores are offering a wide array of special features for clients to enjoy.
To give you a bit of an idea what virtual switch really is, here are some of its key features and the pros and cons that you might want to look into.
Virtual Switch provides a mechanism that reduces the network configuration complexity. This is attained by reducing the number of switches that are to be managed after taking the network size, packets of data, and the account architecture. Because it is a smart technology, it can ensure the profile stability of the virtual machine. This, in turn, is a great help for network administrators since it reduces security risks and mobility time in moving virtual machines across physical hosts.
The Pros and Cons
Using virtual switch has a few advantages.
- One of which is that it helps in easy and smooth deployment and migration of virtual servers.
- It enables network administrators to manage the virtual switches being deployed by a hypervisor.
- Also, compared to a physical switch, virtual switch can easily roll out new functionality which can be hardware or software-related.
However, the switches’ complexities may pose numerous problems if left unmanaged. Thus, these cons will give you a heads-up on the amount of diligence to avoid contingencies later on.
- Open ports on unmanaged switches are a threat to security. This primarily talks about virus intrusion into the system to wreak havoc and to cause damage to the virtual networks.
- If there is no resiliency, then there will be a higher downtime. An important feature of a managed switch is redundancy which addresses cases of connection or cable failure. This feature upholds the ability of network preservation by providing an alternate data path for traffic. In standard data protocols, preventing loops and establishing backup redundant links are implemented to keep the integrated system available. This can promote efficiency since it can prevent downtime.
- An unmanaged switch cannot prioritize traffic. Managed switches provide the ability to prioritize Local Area Network traffic. This ensures that the most significant information will get through. Thus, if it’s left unmanaged, then it will do otherwise.
- Unmanaged switches cannot group a network traffic. Grouping and isolation of network traffic considerably reduce unnecessary traffic in key areas. This will allow better network performance and will provide additional security level.
- Lastly, unmanaged switches have limited or no tools for monitoring network activity or performance. This will not allow users to monitor the network performance and quick detection and reparation of network problems.
CISCO Systems Incorporated, which is an American multinational technology conglomerate, has developed new APIs (application programming interface). This new development allows customers to choose a virtual switch that befits their unique network and data center requirements.
Virtual switch, therefore, is not just an ordinary communicatory medium. But, it also aids and supports organizations as they climb up the steep ladder of competition and innovation.
