Abstract
Abstract A system and method are provided for securely establishing Layer-3 SVCs or SPVCs across an ATM network. An originating multiservice switch that generates the connection setup message for the Layer-3 connection includes security information within the setup message, such as a Closed User Group Interlock Code. When the destination multiservice switch receives the setup message, it extracts the embedded security information and compares it with stored security information corresponding to the connection. The correspondence may be determined from the destination user. If the embedded security information matches the stored security information, the destination multiservice switch allows the connection to be established.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A method of establishing a secure Layer-3 connection across an ATM
network, the Layer-3 connection having a first endpoint at an egress port of an
originating multiservice switch (MSS) and a second endpoint at an ingress port
of a terminating MSS, the method comprising the steps of: configuring the terminating MSS with anticipated security information; at the originating MSS, generating a setup message including embedded
security information; sending the setup message to the terminating MSS; at the terminating MSS, extracting the embedded security information
from the setup message; determining whether the embedded security information matches the
anticipated security information; and if the embedded security information matches the anticipated security
information, establishing the Layer-3 connection.
Claim 2
Dependent Claim
32 words
The method of claim 1 wherein the Layer-3 connection is a Soft
Permanent Virtual Circuit, and wherein the embedded security information and
the anticipated security information are associated with the first endpoint.
Claim 3
Dependent Claim
32 words
The method of claim 1 wherein the Layer-3 connection is a Soft
Permanent Virtual Circuit, and wherein the embedded security information and
the anticipated security information are associated with the second endpoint.
Claim 4
Dependent Claim
21 words
The method of claim 1 wherein the embedded security information and
the anticipated security information are Closed User Group Interlock Codes.
Claim 5
Dependent Claim
43 words
The method of claim 1 wherein the Layer-3 connection is established by
an originating user belonging to a configured set of originating users, and
wherein the embedded security information and the anticipated security
information are associated with the configured set of originating users.
Claim 6
Dependent Claim
52 words
The method of claim 1 wherein the Layer-3 connection is established
through an Internet Protocol (IP) interface address at the originating MSS
belonging to a set of configured IP interface addresses, and wherein the
embedded security information and the anticipated security information are
associated with the configured set of IP interface addresses.
Claim 7
Dependent Claim
43 words
The method of claim 1 wherein the Layer-3 connection is established to a
terminating user belonging to a configured set of terminating users, and
wherein the embedded security information and the anticipated security
information are associated with the configured set of terminating users.
Claim 8
Dependent Claim
52 words
The method of claim 1 wherein the Layer-3 connection is established
through an Internet Protocol (IP) interface address at the terminating MSS
belonging to a set of configured IP interface addresses, and wherein the
embedded security information and the anticipated security information are
associated with the configured set of IP interface addresses.
Claim 9
Dependent Claim
50 words
The method of claim 1 comprising the further steps of: at the originating MSS, setting a value of a flag in the setup message to
indicate that the setup message includes embedded security information; at the terminating MSS, reading the value of the flag before extracting the
embedded security information.
Claim 10
Dependent Claim
44 words
An originating multiservice switch (MSS) for establishing a secure
Layer-3 connection across an ATM network to a terminating MSS, comprising a
call control for generating a Layer-3 connection setup message including
embedded security information, and for sending the setup message to the
terminating MSS.
Claim 11
Dependent Claim
35 words
A computer-readable medium comprising: instructions for generating a Layer-3 connection setup message to be sent
from an originating multiservice switch (MSS) to a terminating MSS; and instructions for embedding security information within the setup
message.
Claim 12
Dependent Claim
92 words
A terminating multiservice switch (MSS) for establishing a secure
Layer-3 connection across an ATM network from an originating MSS,
comprising: stored anticipated security information; means for querying a comparator of two pieces of security information;
and a call controller for receiving a Layer-3 connection setup message, for
extracting embedded security information from the setup message, for querying
the comparator to determine whether the embedded security information
corresponds to the anticipated security information, and for establishing the
Layer-3 connection in the event that the embedded security information
corresponds to the anticipated security information.
Claim 13
Dependent Claim
69 words
A computer-readable medium comprising: instructions for receiving a Layer-3 connection setup message received
from an originating multiservice switch; instructions for extracting embedded security information from the setup
message; instructions for retrieving anticipated security information; instructions for determining whether the embedded security information
corresponds to the anticipated security information; and instructions for establishing a Layer-3 connection in the event that the
embedded security information corresponds to the anticipated security
information.
