Method for device addressing using SNMP community string-based routing
View Patent ↗A method of addressing a data packet includes receiving the data packet and creating a packet header for the data packet. The method also includes providing routing information in a community string format in the packet header and communicating the packet header and data packet to a gateway, wherein the gateway is operable to forward the data packet to a destination uniquely defined by the routing information.
1. A method of addressing a data packet, comprising:
receiving the data packet;
creating a packet header for the data packet;
providing routing information in an encoded format in the packet header, wherein the routing information uniquely identifies a destination device; and
communicating the packet header and data packet to a gateway device;
wherein the data packet is formatted in the Simple Network Management Protocol format.
2. The method of claim 1 , wherein the gateway device is operable to communicate the data packet to the destination device identified by the routing information.
3. A method of addressing a data packet, comprising:
receiving the data packet;
creating a packet header for the data packet;
providing routing information in an encoded format in the packet header, wherein the routing information uniquely identifies a destination device; and
communicating the packet header and data packet to a gateway device;
wherein the data packet includes a request packet to be communicated to a destination device.
4. The method of claim 3 , further comprising:
storing an address of an originating device of the request packet;
receiving a response packet from the destination device; and
communicating the response packet to the originating device.
5. The method of claim 4 , further comprising:
waiting to receive a first response packet from the destination device in response to a first request packet communicated to the destination device before communicating a second request packet to the destination device.
6. A method of addressing a data packet, comprising:
receiving the data packet;
creating a packet header for the data packet;
providing routing information in an encoded format in the packet header, wherein the routing information uniquely identifies a destination device; and
communicating the packet header and data packet to a gateway device;
wherein the gateway device is operable to communicate the data packet to the destination device identified by the routing information;
wherein the data packet is communicated to the destination device on an inband management channel.
7. The method of claim 6 , wherein the inband management channel is an LES-EOC management channel.
8. A method of addressing a data packet, comprising:
receiving the data packet;
creating a packet header for the data packet;
providing routing information in an encoded format in the packet header, wherein the routing information uniquely identifies a destination device; and
communicating the packet header and data packet to a gateway device;
wherein the routing information is of the form ProtocolType@<gatewayid>.<slot#>.<port#>.<virtual path identifier>.<virtual circuit identifier>.
9. The method of claim 8 , wherein the <gatewayid> component of the routing information includes an identification of the gateway device along a communication path to the destination device.
10. The method of claim 9 , wherein the <slot#>.<port#> component of the routing information includes an identification of a physical slot and a physical port of the gateway device along a communication path to the destination device.
11. The method of claim 10 , wherein the <virtual path identifier>.<virtual circuit identifier> component of the routing information includes an identification of a specific device as the destination device of the data packet.
12. A method of storing a data packet in a data packet host, comprising:
receiving the data packet;
identifying an originating device of the data packet;
providing location information for the originating device in a community string format in a packet header;
assigning an internet protocol address to the data packet that is the same as an internet protocol address for a routing device; and
routing the packet header and data packet to a storage device.
13. The method of claim 12 , wherein the data packet is formatted in Simple Network Management format.
14. The method of claim 12 , wherein the location information is communicated on an inband management channel.
15. The method of claim 14 , wherein the inband management channel is an LES-EOC management channel.
16. The method of claim 12 , wherein the routing information is of the form ProtocolType@<gatewayid>.<slot#>.<port#>.<virtual path identifier>.<virtual circuit identifier>.
17. The method of claim 16 , wherein the <gatewayid> component of the routing information includes an identification of a gateway device along a communication path from the originating device.
18. The method of claim 16 , wherein the <slot#>.<port#> component of the routing information includes an identification of a physical slot and a physical port of the gateway device along a communication path from the originating device.
19. The method of claim 16 , wherein the <virtual path identifier>.<virtual circuit identifier> component of the routing information includes an identification of a specific device as the originating device of the data packet.
