Abstract: A method of managing a context table for the compression of an IPv6 header based on a context in a wireless mesh network includes: determining, by a boundary router for coupling an external network and a Low-power and Lossy Network (LLN), a score by taking information on the traffic of a packet transmitted by an external host into consideration; assigning, by the boundary router, a Context ID (CID) to the prefix of the packet based on the determined score and registering the CID with a context table: and sending, by the boundary router, the packet of context registered with the context table to all nodes of the LLN.
