- bryogenic 10y ago[MPLS is] ... often referred to as a layer 2.5 protocol. It was designed to provide a unified data-carrying service for both circuit-based clients and packet-switching clients which provide a datagram service model. It can be used to carry many different kinds of traffic, including IP packets, as well as native ATM, SONET, and Ethernet frames. https://en.wikipedia.org/wiki/Multiprotocol_Label_Switching https://en.wikipedia.org/wiki/Multiprotocol_Label_Switching
- revelation 10y agoSure, but what's the application for Ethernet in there? I must come across as dense but Ethernet > MPLS > Ethernet feels like a "let's start over" moment.
- dogecoinbase 10y agoVPLS is the standard use case for this scenario.
- beachstartup 10y agoit's to offer normal ethernet service in buildings that are connected through some other kind of metro network. in other words, it's cheaper than making your customer buy a bunch of weird proprietary network equipment to hook up their office wifi.
- jlgaddis 10y agoPeople want layer 2 connectivity between independent networks for a bunch of different reasons. Look into what's driving VXLAN adoption, for example.
- colanderman 10y agoEthernet over IP is a thing too. Useful for bridging networks over a layer 3 link that you may be forced into for whatever reason.
