What is fronthaul and backhaul networks?

What is fronthaul and backhaul networks?

It refers to the connections between a mobile network and a wired network that backhaul traffic from disparate cell sites to a mobile switching telephone office. Fronthaul is the network architecture that connects the remote cell sites to the BBU, while backhaul links the mobile network to the wired network.

What is a backhaul in networking?

Backhaul, therefore, is the connection between an access node and the core network. A backhaul network is planned according to a number of factors including the required transfer rate, known as bandwidth, and the time it takes for data to go from one point to another, known as latency.

What is fronthaul and backhaul in 5G?

A primary difference between fronthaul and backhaul is the part of the network the technology is deployed on. Backhaul links the mobile network to the wired network, while fronthaul describes the network architecture that connects the remote cell sites to the BBU.

What is a fronthaul connection?

Fronthaul is defined as the fiber-based connection in RAN infrastructure between the Baseband Unit (BBU) and Remote Radio Head (RRH). Fronthaul originated with LTE networks when operators first moved their radios closer to the antennas.

Why is backhaul important?

Wireless backhaul strengthens this connection and provides last-mile aggregation. Rather than jumping through many hoops to reach the internet, there is direct access, as these wireless networks can deliver hundreds of data streams and enable efficient and unbound throughput for data, video and voice.

Why is it called backhaul?

Backhaul, a term probably derived from the trucking industry, has several usages in information technology. 3) According to books we like, backhauling is sending network data over an out-of-the-way route (including taking it farther than its destination) in order to get the data there sooner or because it costs less.

What is VPN backhaul?

VPN based backhaul traffic architecture is a promising ex- emplary to model the LTE backhaul traffic. It can be modeled as a layer 2 VLAN or as a layer 3 VPN. However, moving from a pure layer 2 topology to a full layer 3 VPN architecture has more advantages such as less complexity, flexibility and scalability [3].

What is 5G backhaul?

What is 5G Backhaul? The backhaul of a network consists of links from the core network to subnetworks. In 5G, the mobile network must be linked to the wired network through the backhaul. Thus, 5G backhaul refers to the signal between the 5G core and remote sites or networks.

What is MBH network?

Mobile Backhaul (MBH) is the process of connecting cell site air interfaces to wireline networks, which are subsequently connected to data centers that host the content and applications accessed by mobile users—both human and machine.

What is wireless backhaul?

Wireless backhaul is the use of wireless communication systems to transport data between the internet and subnetworks. It can help an organization or mobile network eliminate the need for physical cabling. The connection between the cell tower and the smartphone is the wireless backhaul.

What are the five layers of 5G architecture?

The components of the 5G core architecture include:

  • User plane Function (UPF)
  • Data network (DN), e.g. operator services, Internet access or 3rd party services.
  • Core Access and Mobility Management Function (AMF)
  • Authentication Server Function (AUSF)
  • Session Management Function (SMF)
  • Network Slice Selection Function (NSSF)
