| 3 | |||
| 4 | The purpose of the Gb proxy is to aggregate the Gb links of multiple |
||
| 5 | BSS's and present them in one Gb link to the SGSN. |
||
| 6 | |||
| 7 | More specifically, the Gb proxy terminates the NS-VCs of each BSS |
||
| 8 | locally. Furthermore, it establishes one NS-VC with the SGSN. |
||
| 9 | |||
| 10 | The proxy then forwards NS-DUs (BSSGP PDUs) between the SGSN and the |
||
| 11 | respective BSS (and vice versa). |

| 20 | 1 | laforge | |
| 21 | You can also cascade multiple Gb proxies behind each other, where a number |
||
| 22 | of BSS connect to one Gb proxy, which in turn connects to another Gb proxy, |
||
| 23 | which then finally connects to the SGSN. |
||
| 24 | |||
| 25 | The reason for this type of use can be broken or limited Gb implementations |
||
| 26 | in proprietary BSS equipment, which fails to re-connect the Gb link after some |
||
| 27 | intermittent network outage. |

| 31 | There's a more detailed [wiki:osmo-gbproxy_design design description] outlining |
||
| 32 | details of the proxy. |
