FCM over UP

[yu-re-ka]

source

``` digraph { subgraph cluster_phone { label="end user device"; microG -> "FCM App e.g. Signal" [color=red] "UP distributor" -> "UP App e.g. SchildiChat" [color=green] "UP distributor" -> microG [color=red] } subgraph cluster_my_server { label="my server"; "eg. gotify" "My FCM Proxy" -> "eg. gotify" [color=red] } "eg. gotify" -> "UP distributor" [color=red] "eg. gotify" -> "UP distributor" [color=green] subgraph cluster_google { label="google" "Google push servers" } "Google push servers" -> "My FCM Proxy" [color=red] "e.g. Matrix push gateway" -> "eg. gotify" [color=green] "e.g. Signal server" -> "Google push servers" [color=red] subgraph cluster_fcm_application_server { label="FCM application server" "e.g. Signal server" } subgraph cluster_up_application_server { label="UP application server" "e.g. Matrix push gateway" } } ```

The advantage:

Only one push connection required on my device Google doesn't see my phone's IP
