Abstract

A network element is described. In one embodiment includes receiving a packet from the host in the first domain at the network element in the first domain, the packet including a destination address to the host in the second domain, the destination address being formed by replacing an Interface Identifier of an IP address by a second domain label and a shortened Media Access Control (MAC) address, the second domain label identifying the second domain. A routing label and the shortened MAC address are attached to the received packet, and the packet is sent on a label switched path indicated by the label to the second domain.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 486100, filed May 13, 2011, entitled "Applying MPLS to the Internet of Things - Tackling the 6LoWPAN Case," which application is hereby incorporated by reference. technical field [0003] Embodiments of the invention relate to the field of routing packets between different domains, and more particularly, to routing packets between low power network domains in order to save power. Background technique [0004] The "Internet of Things" (IoT) is a rapidly emerging paradigm that, among other things, introduces new types of Internet endpoints. In the IoT world, even small devices with limited processing power, low battery power, small memory, and limited networking and service capabilities can become endpoints. These small devices can spend most of their life time in hibernation mode. Such low-power IoT devices can be assigned a wide range of tasks, ...
