Benefits of a Trunking Network (With Tips and Examples)

A network trunk is a communications line or link designed to carry multiple signals simultaneously to provide network access between two points. Trunks typically connect switching centers in a communications system. The signals can convey any type of communications data.

This one-stop shop for everything trunking in the MSP world was established because of this. You will understand the various types of trunking, such as link aggregation, VLAN trunking, SIP trunking, and IP trunking, after reading this article. You will also understand how SIP trunking can increase your revenue as a managed service provider.

What are the advantages of trunking?

Here are some of the advantages of trunking:

Expanded bandwidth

A telecommunications or data network’s bandwidth and capabilities can be increased through tunneling. Multiple users can connect to the same network node using this type of network. The design may allow for better traffic management and direction on the network, reducing congestion that would otherwise slow data processing.

Multiple link aggregation

By itself, truncation enables communication or connection to a location. The network’s trunking feature enables concurrent connections from multiple users to the same source. By joining several Ethernet links together, known as multiple link aggregation, a huge amount of additional potential bandwidth is added. This entails that various ports may connect to the source entity, spreading traffic and getting rid of the restrictions imposed by point-to-point connections. Trunking can connect a variety of entities to a single point with a much greater capacity to handle the traffic volume thanks to its support for multiple link aggregation.

VLAN trunking

You can use the trunking technique known as virtual local area network (VLAN) trunking to help manage data and traffic on a network. A network typically has multiple subnets that switch traffic between ports. Because of the switches’ limitations, network problems like congestion could happen. VLAN trunking can divide network demands and group traffic, preventing the network from becoming overloaded. This implies that the VLAN can construct multiple layers using switches and a subnet in order to manage traffic flow more effectively.

What is a trunking network?

To increase efficiency in data and telecommunication, a trunking network is used. Trunking can allow multiple connections to the same point. Trunking can also occasionally link two different communication nodes or communication centers to a large number of users. Trunking can take place via a fiber-optic connection or by using several that radiate out from the same source. A trunking network consists of a central core and numerous branches that branch out from it. The branches are able to receive, compile, and direct incoming information.

Trunking is frequently used in communication systems and very-high-frequency (VHF) radio communication systems. Trunking allows radio, audio, or visual data to be transmitted from a single location to numerous users. Multiple entities simultaneously connect to a single source entity through trunking.

How does trunking help with VLAN configuration?

Trunking makes it possible for a port to handle incoming traffic much more effectively, which makes it helpful for VLAN configuration. Traffic can be divided into logical patterns and directed through the port by the VLAN configuration. The idea of trunking is crucial because numerous users could establish a link to the VLAN configuration. Trunking serves as the foundation for how traffic enters, while VLAN aids in routing and organizing traffic. Tags are used by the trunking VLAN port to monitor incoming traffic as it travels through subnets and switches.

Access port vs. trunk port

Here is how an access port and a trunk port contrast:

VLAN use

An access port usually handles traffic for a single VLAN. Through a particular VLAN, the connection sends data and communications, which organizes the traffic. The VLAN then separates and groups the traffic and data into logical pieces.

The trunk port transmits data and traffic through multiple VLANs. Multiple VLANs can be used without adding more infrastructure. The various VLANs may also work together by sharing the same cables or lines.

Tag use

The access port only employs a single VLAN, so tagging is not used. As a result, the configuration is less complicated than that of a trunk port. If the access port receives a bit of information that has been tagged, it disregards the tag and processes the information anyway.

The trunk port uses tags to track information. The trunk port’s ability to support multiple VLANs and the tags’ ability to keep data and traffic organized make this necessary. The trunk port configuration is typically more intricate.

Efficiency

Access ports tend to have less efficiency than trunk ports. Because there is only one VLAN used by the access ports, there may be some traffic congestion. The single VLAN can limit the access ports capacity.

Multiple VLANs are supported by the trunk port, which can increase bandwidth and decrease traffic delays. The structure can create layers of organization for the traffic. Information can enter the trunk from various VLANs, where it can be effectively organized and directed to the appropriate location.

3 types of trunking networks

Here are three different types of trunking networks:

Broadcast systems

Multiple entities may be able to share a radio frequency thanks to a trunking radio system. For example, two-way radio systems often use trunking. A group of users can use the same radio system simultaneously thanks to modern radio systems. Governmental organizations frequently make use of trunking radio systems, including emergency responders.

Data networks

Trunking systems are frequently used in data networks to increase bandwidth and build effective networks. For instance, a trunking system and a VLAN could be used to link several network switches, subnets, and ports. The incoming data can then be logically managed by the trunking system by being divided into logical subgroups. Higher bandwidth and lower latency for data transfer are made possible by the VLAN organization and access trunking.

Telephone systems

Trunking in telephone systems first began with landlines. Now that network nodes can be connected to one another through trunking, phone networks can handle massive amounts of data transfer at once. VoIP trunking, which is now used by phone networks, enables a phone company to convert human voices into data.

FAQ

What is VLAN trunking in networking?

A Cisco-exclusive protocol called VLAN Trunking Protocol (VTP) spreads the concept of Virtual Local Area Networks (VLAN) across the entire local area network. In order to accomplish this, VTP sends VLAN information to each switch within a VTP domain. VTP advertisements can be sent over 802. 1Q, and ISL trunks.

What is the meaning trunking?

Trunking is defined as using a trunk in one way or another. 2a : a casing to protect electrical conductors. the provision of adequate trunks and switching facilities in either a manual or automatic communications system, in the sense of 5d(1) 3a. b : the interconnections provided.
