Subnet Routing

The network interfaces of the WAN1, WAN2, LAN, and DMZ are configured with different sub-network inter- faces, which enable them to perform the routing process with each other.

Routing Protocol

The OfficeServ 7200 supports routing information-exchange protocols to react to the changing network environment more effectively.

•RIPv1, RIPv2: These protocols are widely used for managing the routing information in a mid-sized inde- pendent network such as a group of LANs.

•OSPFv2: This routing protocol is used in larger independent networks. A router detects and reports any change in the routing table or the network to other routers. This way, all routers share the same routing information.

Routing Between the VLAN Groups

Communication between the VLAN groups.

CBQ (Clss Based Queuing)/BoD (Bandwidth on Demand)

The queuing process is differentially performed according to the level table where the routing process priority for a data server is defined.

RTP Priority

The RTP(Real-Time Transport Protocol) packet is a VoIP media packet.

Prioritizes RTP voice packets over normal data packets for improved voice quality in VoIP applications.

IP-ToS Process

This function checks the ToS(Type of Service) field of the IP header and processes it according to priority of the corresponding routing in the data server. This function reproduces the ToS field flowing into the data server, performs the routing process first, and heightens the process priority in the next HOP.
