• bp-dcn-gw-ip: This address is in the same subnetwork as the bp-dcn-ip of this
node.
• bp-dcn-mask: The address mask of the bp-dcn-ip of this node.
The IP address of the TransAccess Mux will have the following characteristics:
• IP address: This IP address can be on the same subnetwork as the node bp-dcn-ip.
• Gateway: This IP address is the bp-dcn-ip of the node.
• Mask: This mask is the address mask of the bp-dcn-ip of the node.
• Trap-1: This address is the bp-dcn-ip of the node to which it is connected.
Quality of
Service
The IP QoS (IP Quality of Service) routing protocol enables a Traverse node to
broadcast its forwarding table over the backplane for the data control network
(bp-dcn-ip), thus improving the quality of service over the backplane DCN ethernet
interface. Setting up static routes on intermediate routers between the Traverse
management gateway element and the TransNav management server is no longer
necessary. Existing traffic engineering and security capabilities are not changed.
When IP QoS is enabled on the management gateway node during commissioning,
source IP address packets are user-configured to block or allow traffic originated by
certain IP hosts or networks using the access control list (ACL). Received packets are
filtered, classified, metered, and put in queue for forwarding.
The ACL searches received IP address packets for the longest prefix match of the
source IP address. When the address is found, it is dropped or forwarded according to
the ACL settings (permit or deny). If no instruction is present in the ACL, the packet is
forwarded.
Outgoing IP address packets are prioritized as either High Priority or Best Effort and
put in queues for forwarding. The queue size for outgoing address packets is set by the
percent of available bandwidth.
