The step of modifying packets further comprises the steps of detecting the movement of a mobile node, and updating the movement of the mobile node to other nodes. The step of detecting the movement of the mobile node further comprises a step of replacing the prefix in the receiving packets before passing the receiving packets to the non-mobility-capable IPv6 module of the internet layer for hiding the movement of the mobile node; The step of modifying the packets also comprises the steps of adding extension headers to the packets, deleting extension headers from the packets and replacing IP addresses of the packets for the survivability of the ongoing connections. | 05-28-2015 |
20150373155 | METHOD OF MODIFYING PACKETS TO A GENERIC FORMAT FOR ENABLING PROGRAMMABLE MODIFICATIONS AND AN APPARATUS THEREOF - Embodiments of the apparatus for modifying packet headers relate to a rewrite engine that represents each protocol header of packets in a generic format specific to that protocol to enable programmable modifications of packets, resulting in hardware and software flexibility in modifying packet headers. Software programs generic formats in a hardware table for various protocols. The rewrite engine is able to detect missing fields from a protocol header and is able to expand the protocol header to a maximum size such that the protocol header contains all possible fields of that protocol. Each of the fields has the same offset irrespective of which variation of the protocol the protocol header corresponds to. In a bit vector, all newly added fields are marked invalid (represented by 0), and all existing fields are marked valid (represented by 1). Software modification commands allow data to be replaced, removed and inserted. | 12-24-2015 |
20160100039 | PROTOCOL CONVERTER - The disclosure relates to a protocol converter that converts between a Modbus protocol and an ECHONET Lite protocol to enable communication between a device performing communication based on a Modbus protocol and a device performing communication based on an ECHONET Lite protocol. The protocol converter according to the disclosure comprises a first communicator connected to a first device that performs communication in a first protocol, a second communicator connected to a second device that performs communication in a second protocol, and a controller that converts the first protocol and the second protocol with each other to control communication between the first device and the second device. | 04-07-2016 |
