VT AIR

Networking

VT AIR is not only equipped with strong high-availability functionalities, VT AIR also offers high firewall performance and a variety of options for using and configuring interfaces.

Networking

High Availability

VT AIR is fully equipped with high-availability functionality. Users can use virtual IPs (VRRP) between multiple VT AIRs to enable failover without failure. The VT AIR configuration is automatically transferred from the leader to the followers and DHCP can also be used in HA operation to compensate for a failure. High availability is a must for critical installations – and VT AIR enables smooth operation.

 

BGP/OSPF

FRR is used for dynamic routing, which allows BGP and OSPF (v4 or v6).

Firewall Performance

VT AIR offers high firewall performance with NFTables, Flowtable Offload Technology and future XDP/eBPF.

Interfaces

VT AIR offers a variety of options for using and configuring interfaces. Real Interface, VLAN, QinQ, Bond, Bridge, PPP, PPTP, GRE, IPIP, SIT SHDSL, VDSL and MacVLAN are supported. In addition, various settings can be made IPv4/IPv6, Static IP, DHCP Client, SLAAC, Mac, MTU, MSS, Link Mode, 802.1x (Supplicant) … and much more.

QoS
QoS is implemented with the Linux tool Traffic Control (TC) and allows incoming (ingress) or outgoing (egress) traffic to be classified according to categories and rules. QoS can easily be assigned to clients via firewall rules.

Routing

VT AIR offers static and dynamic routes. Gateways can be monitored using ping and intelligently interconnected in routing tables, either in failover or load balancing. Policy routing can also be defined via firewall rules or clients can be assigned a routing table. FRR is used for dynamic routing, which allows BGP and OSPF (v4 or v6).

  • DHCP in HA mode

  • XDP/eBPF

  • Dynamic Routing (FFR)

Info

XDP (eXpress Data Path) ist ein eBPF-basierter Hochleistungsdatenpfad, der zum Senden und Empfangen von Netzwerkpaketen mit hohen Raten verwendet wird, indem der größte Teil des Netzwerkstapels des Betriebssystems umgangen wird. Es ist sein Version 4.8 in den Linux-Kernel eingebunden (wikipedia)
