Abstract
Provided are a system and method for transferring management channel information (inband or using path overhead) over a synchronous optical network (SONET). In one example using inband management information, the method includes encapsulating management information in an internet protocol (IP) packet and encapsulating the IP packet in an Ethernet frame. The Ethernet frame is tagged with a management tag to differentiate the frame from the data traffic sent via the network.
Claims16
A method for transferring management channel information inband with data traffic over a synchronous optical network, the method comprising:
- encapsulating management information in an internet protocol (IP) packet;
- encapsulating the IP packet in an Ethernet frame;
- tagging the Ethernet frame with a management tag to differentiate the frame from the data traffic;
- and
- sending the Ethernet frame via the network.
A system for transferring management channel information inband with data traffic over a synchronous optical network, the system comprising:
- first and second path terminating network entities connected via the network;
- first and second virtual local area networks (VLANs), wherein a portion of each VLAN includes the first and second network entities;
- and wherein the first VLAN is for data traffic and the second VLAN is for management traffic;
- and
- software for managing the transfer of management information between the first and second network entities, the software including:
- instructions for encapsulating management information in an internet protocol (IP) packet;
- instructions for encapsulating the IP packet in an Ethernet frame;
- instructions for tagging the Ethernet frame with a management tag to designate the frame for the second VLAN;
- and
- instructions for sending the Ethernet frame via the network.
