Abstract
Abstract A packet encapsulation scheme for multiplexing application sessions ― Lightweight IP Encapsulation (LIPE) ― is described. An LIPE packet comprises at least one multiplexing header (MH) and associated multimedia data packet (MDP). The LIPE packet uses UDP/IP as transport. An MH field further comprises a 16-bit a user identifier (UID) field, an 11 bit length indicator (LNG) field, a 1 bit "more" (M) field and an optional payload type/class of service (PT/CoS) field comprising 8 bits.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
34 words
A method for use in a packet server, the method comprising the steps of: receiving a number of incoming data packets; and formatting the incoming data packets in accordance with Lightweight IP
Encapsulation (LIPE).
Claim 2
Dependent Claim
19 words
The method of claim 1 wherein the formatting step encapsulates LIPE packets
using Internet Protocol/User Datagram Protocol (IP/UDP) transport.
Claim 3
Dependent Claim
79 words
The method of claim 2 wherein the format for an encapsulated LIPE packets
using (IP/UDP) transport comprises an IP header field, a UDP header field and at least
one multiplexing header and an associated multimedia data packet, wherein the
multiplexing header comprises a user identifier field, a length indicator field, and a more
field, the more field being used to indicate the use of more than one multiplexing header
and associated multimedia data packet for transporting incoming data packets.
Claim 4
Dependent Claim
67 words
The method of claim 1 wherein a packet formatted in accordance with LIPE
comprises at least one multiplexing header and an associated multimedia data packet
wherein the multiplexing header comprises a user identifier field, a length indicator field,
and a more field, the more field being used to indicate the use of more than one
multiplexing header and associated multimedia data packet for transporting incoming data
packets.
Claim 5
Dependent Claim
35 words
The method of claim 1 wherein a packet formatted in accordance with LIPE
comprises at least one multiplexing header and an associated multimedia data packet
wherein the multiplexing header comprises a class of service field.
Claim 6
Dependent Claim
34 words
The method of claim 5 wherein the class of service field further comprises a
number of bits representative of a payload type and a remaining number of bits
representative of a quality of service.
Claim 7
Dependent Claim
20 words
The method of claim 6 wherein the number of bits representative of the payload
type represent different voice coding schemes.
Claim 8
Dependent Claim
37 words
An improved apparatus for transporting packets, the improved apparatus
comprising a packet server for (a) a receiving a number of incoming data packets; and (b)
formatting the incoming data packets in accordance with Lightweight IP Encapsulation
(LIPE).
Claim 9
Dependent Claim
21 words
The improved apparatus of claim 8 wherein the packet server further
encapsulate LIPE packets using Internet Protocol/User Datagram Protocol (IP/UDP)
transport.
Claim 10
Dependent Claim
80 words
The improved apparatus of claim 9 wherein the format for an encapsulated
LIPE packets using (IP/UDP) transport comprises an IP header field, a UDP header field
and at least one multiplexing header and an associated multimedia data packet, wherein
the multiplexing header comprises a user identifier field, a length indicator field, and a
more field, the more field being used to indicate the use of more than one multiplexing
header and associated multimedia data packet for transporting incoming data packets.
Claim 11
Dependent Claim
68 words
The improved apparatus of claim 8 wherein a packet formatted in accordance
with LIPE comprises at least one multiplexing header and an associated multimedia data
packet wherein the multiplexing header comprises a user identifier field, a length indicator
field, and a more field, the more field being used to indicate the use of more than one
multiplexing header and associated multimedia data packet for transporting incoming data
packets.
Claim 12
Dependent Claim
36 words
The improved apparatus of claim 8 wherein a packet formatted in accordance
with LIPE comprises at least one multiplexing header and an associated multimedia data
packet wherein the multiplexing header comprises a class of service field.
Claim 13
Dependent Claim
35 words
The improved apparatus of claim 12 wherein the class of service field further
comprises a number of bits representative of a payload type and a remaining number of
bits representative of a quality of service.
Claim 14
Dependent Claim
21 words
The improved apparatus of claim 13 wherein the number of bits representative
of the payload type represent different voice coding schemes.
