MPLS and Fiber are two transport technologies commonly used in networking.
Multiprotocol Label Switching (MPLS) is a layer 2.5 packet forwarding protocol that employs labels to efficiently forward data packets in a network.
In this article, we will delve into MPLS vs. Fiber, exploring the major differences between these two networking technologies.
MPLS vs. Fiber: 9 Key Differences
- Packet Forwarding: MPLS is a packet forwarding algorithm that uses labels to make forwarding decisions, while Fiber is a physical cable used to transmit data over long distances.
- Network Layer: MPLS operates at Layer 2.5 of the OSI model to make its packet forwarding decisions, while Fiber optic cables function at Layer 2 of the OSI model, enabling data transmission from one end to another in a network.
- Implementation: MPLS can be implemented on a network that uses fiber-optic cables as the physical medium for data transmission.
- Application: MPLS provides the capability of creating virtual private networks (VPNs) with enhanced security and traffic prioritization. Fiber, as a physical medium, is used as the foundation for various network topologies, including point-to-point, point-to-multipoint, and mesh configurations.
- Service Quality:MPLS can offer Quality of Service (QoS) features. It ensures that critical applications receive priority treatment and sufficient bandwidth. Fiber’s high data throughput capabilities enable MPLS to deliver consistent and reliable service quality.
- Coverage Capability: MPLS is primarily suited for Metropolitan Area Networks (MANs) and Wide Area Networks (WANs) due to its capability to connect geographically dispersed locations. Fiber, as the physical medium, is not limited by coverage and can be deployed in various network architectures, including local Area networks, wide-area networks, and networks that require long-distance connections.
- Bandwidth Capacity: MPLS can offer high bandwidth capacity, ranging from 10 Mbps to 100 Gbps, depending on the network infrastructure and service provider. Fiber-optic cables are known for their high data transmission capabilities. It can support network speeds of up to terabits per second.
- Cost: The cost of implementing MPLS can be high due to the complexity involved in setting up the label-switched paths and the required network equipment. Fiber-optic deployment costs can also be high, especially for long-distance applications.
- Components: MPLS involves the use of label-switching routers (LSRs) and Label edge routers (LERs)as key components to establish and maintain label-switched paths. On the other hand, Fiber as a medium requires fiber-optic cables, connectors, and transceivers as the primary components for transmitting data.
Conclusion
MPLS and Fiber are two networking technologies that can be used in networks. MPLS handles the packet forwarding decision using labels, while Fiber serves as the physical cable on which MPLS operates. The combination of MPLS and Fiber empowers network operators to create scalable, secure, and high-performance networks that cater to diverse communication needs.
