Method and apparatus for transmitting a cell and a packet in a network
First Claim
1. A method of transmitting a fixed-length cell and a variable-length packet in one network comprising:
- attaching a header corresponding to communication protocol in a mixed network in which both of a variable-length packet and a fixed-length cell are transmitted to a variable-length packet, while removing a cell header from a fixed-length cell and attaching a header corresponding to the communication protocol in the mixed network instead; and
transmitting said fixed-length cell and said variable-length packet in the mixed network on the basis of the respective headers.

Abstract
Disclosed is a transmitting apparatus for transmitting a fixed-length cell and a variable-length packet together in one network. A first IF portion of the transmitting apparatus attaches a header corresponding to the protocol of a mixed network to a variable-length packet which arrives from a packet network and transmits it to the mixed network. A second IF portion removes the cell header from a fixed-length cell which arrives from a fixed-length cell network, attaches a header corresponding to the protocol of the mixed network instead, and transmits it to the mixed length. A third IF portion judges whether a data with a header which arrives from the mixed network is a fixed-length cell or a variable-length packet, replaces the header of the mixed network by a cell header if the data is a fixed-length cell and transmits the data to a fixed-length cell network, while removing the header of the mixed network if the data is a variable-length packet, and transmits the data to a packet network.

2. A method of transmitting of a fixed-length cell and a variable-length packet in one network comprising:
-
attaching a header corresponding to the communication protocol in a mixed network in which both of a variable-length packet and a fixed-length cell are transmitted to a variable-length packet and transmitting said variable-length packet to the mixed network, when said variable-length packet arrives from a packet network;
removing a cell header from a fixed-length cell and adding a header corresponding to the communication protocol in the mixed network instead, and transmitting said fixed-length cell to the mixed network, when said fixed-length cell arrives from a fixed-length cell network;
judging whether data with a header is a fixed-length cell or a variable-length packet when said data arrives from the mixed network, and replacing the header of the mixed network by a cell header and transmitting said data to the fixed-length cell network if said data is a fixed-length cell, while removing the header of the mixed network and transmitting said data to the packet network if said data is a variable-length packet. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)

11. A transmitting apparatus for transmitting a fixed-length cell and a variable-length packet in one network comprising:
-
a first means for attaching a header corresponding to communication protocol of a mixed network to a variable-length packet which arrives from a packet network and transmitting said variable-length packet to said mixed network;
a second means for removing a cell header from a fixed-length cell which arrives from a fixed-length cell network, attaching a header corresponding to said communication protocol of said mixed network and transmitting said fixed-length cell to said mixed network; and
a third means for judging whether a data with the header of the mixed network which arrives from the mixed network is a fixed-length cell or a variable-length packet, and replacing the header of the mixed network by a cell header and transmitting said data to a fixed-length cell network if said data is a fixed-length cell, while removing said header of the mixed network and transmitting said data to a packet network if said data is a variable-length packet. - View Dependent Claims (12)
