The compression method used for network packets. These have different tradeoffs of compression speed versus bandwidth, you may need to test which one works best for your use case if you use compression at all.

+ Enable or disable the server feature that notifies clients of other peers' connection/disconnection, and relays messages between them. When this option is [code]false[/code], clients won't be automatically notified of other peers and won't be able to send them packets through the server.

<member name="transfer_channel" type="int" setter="set_transfer_channel" getter="get_transfer_channel" default="-1">
Set the default channel to be used to transfer data. By default, this value is [code]-1[/code] which means that ENet will only use 2 channels, one for reliable and one for unreliable packets. Channel [code]0[/code] is reserved, and cannot be used. Setting this member to any value between [code]0[/code] and [member channel_count] (excluded) will force ENet to use that channel for sending data.
