11.5 DCC Tunnels
SONET provides four DCCs for network element (NE) operation, administration, maintenance, and
provisioning (OAM&P): one on the SONET Section layer (DCC1) and three on the SONET Line layer
(DCC2, DCC3, and DCC4). The ONS 15454 uses the Section DCC (SDCC) for ONS 15454 management
and provisioning. An SDCC and Line DCC (LDCC) each provide 192 Kbps of bandwidth per channel.
The aggregate bandwidth of the three LDCCs is 576 Kbps. When multiple DCC channels exist between
two neighboring nodes, the ONS 15454 balances traffic over the existing DCC channels using a load
balancing algorithm. This algorithm chooses a DCC for packet transport by considering packet size and
DCC utilization. You can tunnel third-party SONET equipment across ONS 15454 networks using one
of two tunneling methods: a traditional DCC tunnel or an IP-encapsulated tunnel.
