A network device for processing data packets includes an encryption services module, a number of network interfaces and a forwarding module. Preferably, these isochronous data packets make up frames of video data. Large loads can be lowered and raised from the seabed at large water depths such as at 3000 m. The PEGylated imidazolium iodides synthesized in the present work have conductivities in the range 1. The anchor connects to the housing by entering an open end, and being pulled through to an end where it is strapped.
