  • Publication number: 20190287697
    Abstract: The present invention discloses a metal wire armored optoelectronic hybrid cable, which comprises an optoelectronic hybrid unit, a metal wire armoring and an outer protection casing. The optoelectronic hybrid unit comprises an electrical unit and an optical unit which are mixed. The metal wire armoring wraps the optoelectronic hybrid unit. The outer protection casing wraps the metal wire armoring. In the present invention, due to the use of the metal wire armoring, the bending performance is favorable, the production and processing processes are simple, and the production cost of the hybrid cable is greatly reduced.

  • Patent number: 8472384
    Abstract: GPRS Tunneling Protocol (“GTP”) packets are intercepted by receiving a GTP tunnel packet, determining whether the GTP tunnel packet is to be intercepted, intercepting GTP tunnel packets if it is determined that the GTP tunnel packet is to be intercepted, and processing the intercepted GTP tunnel packets. Multiple tunnels may be intercepted simultaneously and GTP tunnel packets from different tunnels may be processed differently. Implementations include both inline and offline interception of GTP traffic between SGSN and GGSN.
