Abstract
In general, in one aspect, the disclosure describes a method of channeling a protocol data unit. The method includes receiving a protocol data unit having a label, accessing data identifying a channel associated with the label, and transmitting the protocol data unit via the identified channel.
Claims37
A method of channeling a protocol data unit, the method comprising:
- receiving a protocol data unit having a label;
- accessing data identifying a channel associated with the label;
- and
- transmitting the protocol data unit via the identified channel.
1 more element
Instructions for causing a processor to:
- access information included in a protocol data unit received over a network connection, the accessed information including a label;
- access data identifying a channel associated with the label;
- and
- cause the protocol data unit to be transmitted via the identified channel.
1 more element
A method of channeling an Internet Protocol (IP) packet, the method comprising:
- requesting a first MPLS (Multi-Protocol Label Switching) label from a network router for delivery of messages from a downstream entity to the router;
- sending a message to the router destined for the downstream entity;
- receiving, in response to the message, a request from the router for a second MPLS label for delivery of messages to the downstream entity;
- storing data associating the second MPLS label with identification of a channel of a channelized carrier servicing the downstream entity;
- receiving the Internet Protocol packet from the network router, the packet having the second MPLS label and a destination address;
- identifying the channel associated with the second MPLS label;
- stripping the label from the packet;
- transmitting the packet via the identified channel;
- dechannelizing a packet received from the downstream entity via the identified channel;
- and
- forwarding the dechannelized packet to the router.
8 more elements
An apparatus for channelizing protocol data units, the apparatus comprising:
- a first interface, the first interface being to a channelized network carrier;
- a second interface, the second interface being to a non-channelized network carrier;
- a multiplexer for channelizing data for transmission over the channelized network carrier;
- a processor for executing instructions;
- and
- storage, the storage storing:
- data associating different labels with different respective channels of the channelized network carrier;
- and
- instructions for causing the processor to:
- receive a protocol data unit via the second interface, the protocol data unit having a label;
- access the data to identify a channel associated with the protocol data unit label;
- and
- transmit the protocol data unit via the multiplexer over the identified channel.
