Description

The existing osmo-gbproxy supports "NS over FR over GRE over IP" as stacking. This assumes there is an external device that converts from FR/E1 to FR/GRE/IP. In the past, this was a standard feature by Cisco routers, but apparently today this feature is no longer present in supported hardware/OS.

In order to continue to support users with Frame Relay based Gb interface, we should hence implement native support for FR/E1.

In terms of E1/T1 hardware, we should focus on DAHDI, as the quad/octal E1/T1 cards are still actively sold on the market.

History

  • Status changed from New to In Progress
  • Assignee set to lynxis
  • Priority changed from Normal to Urgent
  • % Done changed from 0 to 90

the laforge/wip-fr branch of libosmococre contains lynxis' ns2 FR code, which has shown basic FR support works now from osmo-gbproxy (which has recently been ported to ns2).

#2 Updated by laforge about 2 months ago

  • Status changed from In Progress to Resolved
  • % Done changed from 90 to 100

The ns2_fr code is merged and can be used. There are bugs, but for those we create separate issues.
