VDSL
What is Advantage and Disadvantage of VDSL ?
VDSL (Very-high-bit-rate Digital Subscriber Line) internet is a high-speed internet technology that provides faster internet speeds than ADSL over existing copper telephone lines. VDSL is a development of ADSL, but with higher speeds and better performance, this technology is specifically designed for high-bandwidth applications such as video streaming, gaming and large file transfers.
VDSL internet makes use of high-frequency bands to transmit digital data over traditional phone lines. The technology uses a modulation method called Discrete Multi-Tone (DMT) that splits the available bandwidth into multiple channels that can be used for both upstream and downstream traffic. This enables users to have faster download and upload speeds compared to ADSL.
VDSL technology can provide speeds of up to 100 Mbps, depending on the distance between the user and the internet service provider. However, the more significant part of VDSL is that it can provide symmetrical speeds, providing users with similar upload and download speeds compared to ADSL.
One of the primary advantages of VDSL is its speed. With the bandwidth speed increase, users can enjoy faster internet speeds and better connectivity. With faster download and upload speeds, users can perform large file transfers, online gaming, and video streaming more quickly and efficiently.
Another advantage of VDSL technology is that it is compatible with existing copper telephone lines. This means that users do not need to have new infrastructure installed to get VDSL internet, which makes it an affordable option for many households and businesses.
Despite its many benefits, VDSL technology can have some limitations. Distance from the ISP can affect the performance of VDSL technology. The distance between the user and the ISP should be less than two kilometers to maintain speeds of up to 100 Mbps.
In conclusion, VDSL internet is an improvement to traditional ADSL technology, offering faster speeds and better performance. Its compatibility with existing infrastructure and affordable pricing make it an attractive option for many households and businesses. Although limitations exist concerning distance from the ISP, VDSL internet technology is an excellent solution that will continue to serve users worldwide.

What is VDSL2?
Very-high-bit-rate digital subscriber line 2
Very-high-bit-rate digital subscriber line 2 (VDSL2) is an access technology that exploits the existing infrastructure of copper wires that were originally deployed for traditional telephone service as a way of delivering very-high-speed internet access. The main high-speed link (e.g. a fiber optic connection) terminates at a hub near the customers' location. The existing copper wire infrastructure is then used to carry the high speed connection for the short remaining distance to the customers. It can be deployed from central offices, from fiber-optic connected cabinets located near the customer premises, or within buildings. It has been defined in standard ITU-T G.993.2 finalized in 2005.

VDSL2 is an enhancement of VDSL, which was standardized in ITU-T G.933.2. VDSL2 use frequencies of up to 30 MHz to provide data rates exceeding 100 Mbit/s simultaneously in both the upstream and downstream directions. The VDSL2 is capable to support wide deployment of triple play services includes voice, video, data and general Internet access.

LAMBDA (λ) is a term used in telecommunications to refer to a wavelength of light in fiber-optic communications. It is a technology that multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. The LAMBDA λ is a point-to-point DWDM service, which can replace the Dark Fiber service and eliminate the need of repeaters between the service end-points. The LAMBDA λ is capable of transmission of any type of upper layer protocols (for example Ethernet, SDH, etc.) and offers the possibility of transmitting the same capacity point-to-point as would one fiber without the WDM technology.

what is MPLS
MPLS | What Is Multiprotocol Label Switching
Before we dive into MPLS, let’s explain how data travels through the internet. When you send an email, connect to VoIP or video conferencing, that data packet or IP packet is sent from one internet router to its destination. The internet router must decide for each IP packet/data packet how it’s sent to the destination IP. Each packet requires a decision, which the router uses complex routing tables to determine. Every path the packet arrives at requires another forwarding decision until it arrives at its destination. This process can result in poor performance for users, the applications they are using and impact the network across an organization. MPLS provides an alternative for organizations to increase network performance and improve user experience.
MPLS Meaning
Multiprotocol Label Switching, or MPLS, is a networking technology that routes traffic using the shortest path based on “labels,” rather than network addresses, to handle forwarding over private wide area networks. As a scalable and protocol-independent solution, MPLS assigns labels to each data packet, controlling the path the packet follows. MPLS greatly improves the speed of traffic, so users don’t experience downtime when connected to the network.
MPLS Network
An MPLS network is Layer 2.5, meaning it falls between Layer 2 (Data Link) and Layer 3 (Network) of the OSI seven-layer hierarchy. Layer 2, or the Data Link Layer, carries IP packets over simple LANs or point-to-point WANs. Layer 3, or the Network Layer, uses internet-wide addressing and routing using IP protocols. MPLS sits in between these two layers, with additional features for data transport across the network.
What Is MPLS Used For
Organizations often use this technology when they have multiple remote branch offices across the country or around the world that need access to a data center or applications at the organization’s headquarters or another branch location. MPLS is scalable, provides better performance and bandwidth, and improves user experience compared to traditional IP routing. But it is costly, difficult to deliver globally and lacks the flexibility to be carrier independent.
As organizations move their applications to the cloud, the traditional MPLS hub-and-spoke model has become inefficient and costly because:
- It requires backhauling traffic through the organization’s headquarters and out to the cloud instead of connecting to the cloud directly, which impacts performance significantly.
- As companies add more applications, services and mobile devices to their networks, the demand for bandwidth and cloud expertise increases costs and operational complexity.
How MPLS Networks Work for Cloud Adoption
MPLS networks were designed as an overlay tactic to simplify and improve performance. However, routing cloud traffic is not easy with MPLS. To make cloud traffic more efficient, many organizations are exploring how to supplement MPLS with other types of connections, such as:
- MPLS offloading: By using a direct-to-internet connection, an organization can offload the traffic that was bound for the web in the first place. This way, the MPLS circuit only carries the traffic intended for headquarters. The question is how to address security for branch internet connections. An organization might have to add a full stack of security products at the branch, which introduces complexity, or it might forward internet traffic through a proxy, which doesn’t provide the same level of security or inspect non-web traffic.
- MPLS replacement with direct-to-internet: An organization might completely replace an MPLS circuit with an internet connection at a branch office. Although a direct connection is more efficient for access to the cloud, it creates challenges regarding how to set up networking with the same connectivity and reliability as the MPLS environment and questions about how to implement security.
- Internet-augmented MPLS with SD-WAN: A software-defined wide area network (SD-WAN) allows an organization to increase its flexibility by augmenting its MPLS with affordable broadband internet links or replacing it with internet to optimize branch networking decisions based on the application, networking and bandwidth requirements.
