Abstract:
A binding cache management apparatus in an IPv6(Internet Protocol version 6) routing system and a method thereof are provided to efficiently construct the hardware binding cache tables of subscriber cards by processing mobile IPv6 control packets through a mobile IPv6 stack, creating a binding cache table, updating an internal binding cache table using it, and requesting the addition or deletion of binding entries to a subscriber card according to an update result. A binding cache management apparatus in an IPv6 routing system comprises a kernel(21) and a mobile IPv6 client(22). The kernel(21) processes mobile IPv6 control packets through a mobile IPv6 stack, creates a binding cache table, and forwards it to the mobile IPv6 client(22). The mobile IPv6 client(22) updates its own internal binding cache table(221) by using the binding cache table forwarded from the kernel(21), and requests a subscriber card(23) to add or delete a binding entry according to an update result.
