P2MP MPLS: Point to multipoint

Multiprotocol label switching (MPLS) is a routing method directing data between nodes using short paths, rather than long network addresses. The advantage of this is that there’s no need for complicated route processing and so it speeds up traffic flows.

What is P2MP MPLS?

Multiprotocol label switching (MPLS) is a routing method directing data between nodes using short paths, rather than long network addresses. The advantage of this is that there’s no need for complicated route processing and so it speeds up traffic flows.

P2MP MPLS stands for point-to-multipoint multiprotocol label switching. Essentially, it’s an efficient, faster routing technique for pushing data to numerous destinations. It’s used for multicasting – simultaneous data transfer to a group of destination computers – because it’s both reliable and meets the high bandwidth requirements. Examples of multicasting include IPTV, multimedia conferences and multiplayer online games, each of which place great demands on networks.


What are the benefits of using P2MP MPLS?

Aside from the obvious benefits of being able to handle the data and speed requirements of multicasting, P2MP MPLS gives organisations numerous other advantages.

One advantage it has over IP multicasting, in particular, is the ability to reserve bandwidth, which presents options for transmitting extremely large amounts of data. And rerouting after any failures is also quicker than it is with IP multicasting: 10-50 milliseconds against hundreds of milliseconds to a few seconds.

What is P2MP Ethernet used for?

P2MP (point-to-multi-point) Ethernet is used in scenarios where there is a central location, for example a Data Centre, which needs to connect to multiple remote sites, but where each remote site must not communicate directly with one another. This can be used when a provider hosts services for multiple customers from their Data Centre but does not want to permit direct connectivity between customers.

It is possible to facilitate communication between remote sites but only via a device like a router or firewall hosted at the central site. This is often a much more efficient way to connect the Data Centre or central site, using one large connection from the Data Centre to the service provider, which can be divided up into several connections to remote sites, rather than having a separate P2P circuit between the Data Centre and each remote site.

Ethernet FAQs

Take a look at our FAQs for Ethernet

  • What is Ethernet connectivity?


    Simply put, business Ethernet or carrier Ethernet is the most common type of connectivity used today, enabling high-bandwidth connectivity for businesses across the country. It comprises a fibre connection that runs from the network directly to your premise. Before understanding why Ethernet is vital for business bandwidth it's important to know what is Ethernet connectivity.


  • What is Ethernet over FTTx?


    Ethernet over FTTx is a hybrid Ethernet connectivity solution. It enables businesses not yet ready to make the leap to Full Fibre Ethernet to take advantage of its benefits but at more manageable capacities.

    Learn more about our Ethernet over FTTx service and see related content here.

  • What is Ethernet First Mile?


    Ethernet First Mile (EFM) is a popular and affordable way for businesses to get easy, dedicated connectivity that delivers fibre-like connectivity using copper cables already in place and can enable speeds up to 30Mbps – dependent on the length of copper cable needed and how many pairs are used. We provide a breakdown on what Ethernet First Mile is and highlight its top three advantages.

  • MPLS vs SD-WAN


    Multi-Protocol Label Switching (MPLS) has been popular for a number of years now and is very good at providing robust and reliable connectivity as well as ensuring critical business information continues to flow, but it’s flexibility has also become a limiting factor. You can learn more about the differences of MPLS vs SD-WAN here.

  • EPL vs EVPL


    Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL) are Ethernet services defined by the Metro Ethernet Forum (MEF) and fall under their Ethernet services category ‘E-Line’.

    Both EPL and EVPL Ethernet provide the simplicity of private connections combined with the flexibility and scalability of MPLS technology across a range of bandwidths, but the main difference for businesses is the configuration they would require.

  • MPLS vs Dark Fibre


    MPLS can offer robust and reliable connectivity, yet Dark Fibre offers a level of network future-proofing that other means of connectivity can’t. MPLS has been around for a while and has several benefits, we discuss the pros and cons of both, MPLS vs Dark Fibre here.


  • Ethernet vs Dark Fibre


    Ethernet for business is where the bandwidth required is leased from a connectivity provider who manages the network where as Dark Fibre is as it sounds and refers to fibre that is unlit and unmanaged but owned or leased wholly by the business purchasing it. We explore the differences between Ethernet vs Dark Fibre here.

  • What’s the importance of a point-to-point network?

    A point-to-point network gives organisations secure and private connections, for transmitting internal or sensitive data. They are particularly useful for businesses operating over multiple sites, who have to integrate networks and communications, including such bandwidth-hungry activities as the increasingly popular video-conferencing. While some organisations can achieve this integration via the public internet, larger companies may face issues with security, privacy and bandwidth, as well as the reliability of the network. 

    A leased line can provide a solution to these issues, but you may find a point-to-point network is more suitable and, possibly, more economical than a leased line. These networks are available in various bandwidth speeds.

    If your company needs a high capacity, private network to do business, the importance of a point-to-point network cannot be overestimated. Choose the right provider and you’ll get a reliable, high-speed connection perfectly suited to your organisation, at speeds from 10Mbps to 10Gbps.

  • What is the benefit of a point-to-point leased line?

    As well as providing a reliable, private connection, a point-to-point network will give your business a whole host of benefits. One of the most important is speed, with point-to-point networks taking your data along the most direct route possible. Allied to this, upload and download speeds are guaranteed and you won't have any concerns about bandwidth because the connection is private and dedicated.

    Common applications for point-to-point networks include file sharing, data backup, point-to-point VOIP and video-conferencing, all of which take advantage of the direct, high capacity nature of these networks. These networks are ideal for a range of everyday business needs, helping your organisation to work more efficiently.

  • What is a point-to-point circuit?

    This type of private data connection links multiple locations. As a closed network data transport service, it doesn’t use the public internet, making it secure enough to not require any data encryption. 

    Another advantage of this type of connection is the high quality of service: private lines always follow the same direct pathway and don’t have any competing connections on the same line. This means they’re completely reliable as well as secure, making them attractive for companies conducting credit card transactions and similarly sensitive operations. They’re also desirable for organisations transmitting large amounts of data, with many providers offering unlimited data usage.

    Point-to-point circuits are available at different speeds and bandwidths. As a result, they’re as flexible as they are reliable.
