### Address
The address defines the port, and optionally the hostname, on which to listen for incoming connections and packets.
It also defines the protocol to use (TCP or UDP).
If no protocol is specified, the default is TCP.
The format is:
```bash
[host]:port[/tcp|/udp]
```
If both TCP and UDP are wanted for the same port, two entryPoints definitions are needed, such as in the example below.

## Configuring UDP Routers
!!! warning "The character `@` is not allowed in the router name"
### General
Similarly to TCP, as UDP is the transport layer, there is no concept of a request,
so there is no notion of an URL path prefix to match an incoming UDP packet with.
Furthermore, as there is no good TLS support at the moment for multiple hosts,
there is no Host SNI notion to match against either.
Therefore, there is no criterion that could be used as a rule to match incoming packets in order to route them.
So UDP "routers" at this time are pretty much only load-balancers in one form or another.
!!! important "Sessions and timeout"
Even though UDP is connectionless (and because of that),
the implementation of an UDP router in Traefik relies on what we (and a couple of other implementations) call a `session`.
It basically means that some state is kept about an ongoing communication between a client and a backend,
notably so that the proxy knows where to forward a response packet from a backend.
As expected, a `timeout` is associated to each of these sessions,
so that they get cleaned out if they go through a period of inactivity longer than a given duration (that is hardcoded to 3 seconds for now).
Making this timeout configurable will be considered later if we get more usage feedback on this matter.
### EntryPoints
If not specified, UDP routers will accept packets from all defined (UDP) entry points.
If one wants to limit the router scope to a set of entry points, one should set the entry points option.

## Configuring UDP Services
### General
Each of the fields of the service section represents a kind of service.
Which means, that for each specified service, one of the fields, and only one,
has to be enabled to define what kind of service is created.
Currently, the two available kinds are `LoadBalancer`, and `Weighted`.
### Servers Load Balancer
The servers load balancer is in charge of balancing the requests between the servers of the same service.

services:

loadBalancer:
servers:
- address: "xx.xx.xx.xx:xx"
- address: "xx.xx.xx.xx:xx"
```
#### Servers
The Servers field defines all the servers that are part of this load-balancing group,
i.e. each address (IP:Port) on which an instance of the service's program is deployed.
??? example "A Service with One Server -- Using the [File Provider](../../providers/file.md)"
