Welcome to dosiOS Page - Edge Computing Platform
Create your service functions, chain them with virtual switches and physical ports of equipment. Accelerate packet exchange with DPDK.
Use NETCONF protocol and YANG modelisation language for dosiOS management. Perform identification and physical port mapping on initial setup with provided toolkits.
Set the parameters of service function deployment (cpu, ram, ifs, disks) and virtual switch configuration (trunk, access, tag, stacked-vlans).
Available release is ALPHA version available for comments/issues/improvements.
To modify value in dosiOS (epc part of the tree) you need first to delete current value and after set new value. Modification of values not guaranteed and can lead to errors in current stage.
Link to download
Link to download the iso image is presented below
Decryption key (will be asked when start file download)
Repository provides iso image that should be flashed on the usb drive.
1. install qemu 2. qemu-img convert dosios2102.iso -O raw dosiOS-2102.img 3. dd if=dosiOS-2102.img of=/dev/sdX
After booting from usb drive you will be in “cloud image” of dosiOS.
Login: tmpuser Passwd: tmppwd
Confirm that your flash drive is something like /dev/sda and your hard drive is something like /dev/sdb.
Configuration should be performed in the BIOS (HDD priorities)
dosiOS will be installed on the /dev/sdb by default.
You may install dosiOS on the hard drive with the next command:
[email protected]:$ install image
Script of installation will be triggered:
select conf file "/config/config.boot" select console ttyS0 select the console speed 115200 Disk label: gpt

By default Edge Computing Platform is bootstraped with 4GB of hugetables. You may have 16GB ram, thus you want to modify the amount of hugetables to 12GB. To achieve that use the command below ( 6000 x 2 = ~ 12 GB)
config ecp general hugetables 6000
To display the available memory and hugetables type:
show ecp memory free-hugetables
To display the RAM status type:
show ecp memory free-memory
Port identification and mapping
This command helps to identify the connected NICs. Node address + kernel driver (igb)
To identify phy port of the NIC use this command (the phy port will be blinking):
ecp blink-port 0000:0a:00.0 igb // igb kernel driver for 1G NICs (check ecp list-nic-pci)
Next step to map ports to addresses:
configure set ecp interfaces vfpX pci-addr 0000:0a.00.0
2 types of interfaces
The interfaces below represent physical ports of the equipment
The interfaces below represent virtual mgmnt ports connected with representation of physical ports (on the same link) They apper when representation of physical ports is configured on the switch.

Access to Service Functions
To list active Service Function type:
To access virtual serial console of Service Function type:
Add physical port to switch. When the physical port added to switch, you will find new interface dp0pX in the /root/interfaces/dataplane. This dp0pX is configured for management. Confirm that it was configured by
set ecp switches sw1 ports 1 interface vfp1 set ecp switches sw1 ports 2 vm sf1 set ecp switches sw1 ports 2 vm-port 1
