Can BSS use DPDK to process RTP?

1. Brekeke Product Name and Version:BSS 3

2. Java version:1.8

3. OS type and the version:RHEL7

4. UA (phone), gateway or other hardware/software involved:NA

5. Your problem:
Can BSS use the DPDK to process RTP? If not, is it on the roadmap?

Brekeke SIP Server can control Data Plane directly over OpenFlow for processing RTP.

FYI:

What kind of flow is created by BSS?

L2 with EtherType which requires 1 TCAM entry?
L3 which requires 2 TCAM entries?
L2 without EtherType which requires 5 TCAM entries

One SIP call will have 2 legs, does it create 2 flows per call?

I am asking these questions so that we can decide which device to use for the Open flow. We have Cisco 3650 sitting on the shelf which we may use with BSS.

> What kind of flow is created by BSS?

It depends on settings and situations.

Generally 4 flows per call.
- A flow for RTP x 2 legs
- A flow for RTCP x 2 legs

If you want to try OpenFlow and familiar with Linux, I recommend you to try OVS (Open vSwitch).
https://www.openvswitch.org/

Even if you install the OVS in same Linux box where the SIP Server is running, RTP relay performance is raised dramatically because it is processed in Linux kernel module.

For relaying RTP packets at a switch, the switch must support OpenFlow and accept flows for controlling Layer 2,3 and 4.

If you want to use a physical switch instead of OVS software, I recommend that you use OVS based physical switch product.
