Bump In The Wire Transparent Internet Protocol
US Patent:
6606650, Aug 12, 2003
Filed:
Aug 30, 1999
Appl. No.:
09/385389
Inventors:
Earnest E. Hughes - San Antonio TX
John A. Murphy - San Antonio TX
Lewis T. Donzis - San Antonio TX
John A. Murphy - San Antonio TX
Lewis T. Donzis - San Antonio TX
Assignee:
Nortel Networks Limited - St. Laurent
International Classification:
G06F 15167
US Classification:
709213, 709238, 709250
Abstract:
A technique for providing a device referred to as a transparent bump between a local area network and a router. The device is inserted with minimal intrusion to the devices on the LAN to provide a certain operation, such as web caching. The device initializes at start-up in the promiscuous mode to learn the MAC address of the router and subsequently accepts data packets destined to the router for internal processing. Accesses to a web page are checked in the device to determine if cached data is present, so that redundant accesses are reduced. The device initializes and performs its intended function transparently to a user on the local area network.

G06F 15/173
US Classification:
709224
Abstract:
A system, method, and computer readable medium for communicating at least one real-time specially-composed bulletin message to at least one subscriber of a provider of Internet services, comprising a first device, and a second device communicably coupled to the first device, wherein the first device: accesses only subscriber upstream traffic to a destination web site requested by the subscriber, wherein the first device inter-connects between the at least one subscriber and the destination web site, identifies the at least one subscriber's identification based on the accessed subscriber upstream traffic automatically provided by the subscriber, and provides the unique subscriber identification to the second device located at the provider of Internet services providing data services and management control to the first device, wherein the second device determines the subscriber associated with the unique subscriber identification.
Internet Connection User Communications System

International Classification:
G06F 15/173
US Classification:
709224
Abstract:
A method for communicating in real-time to users of a provider of Internet access service, without requiring any installation or set-up by the user, that utilizes the unique identification information automatically provided by the user during communications for identifying the user to provide a fixed identifier which is then communicated to a redirecting device. Messages may then be selectively transmitted to the user. The system is normally transparent to the user, with no modification of its content along the path. Content then may be modified or replaced along the path to the user. For the purposes of establishing a reliable delivery of bulletin messages from providers to their users, the system forces the delivery of specially-composed World Wide Web browser pages to the user, although it is not limited to that type of data. These may be displayed permanently, temporarily, or in separate pop-up browser windows, according to policies set by the provider irrespective of the user's intended browsing destination.
System And Method For Providing Redirections

International Classification:
G06F 15/16, G06F 15/173, G06F 7/06, G06F 17/30
US Classification:
709205, 709242, 709224, 707E17014
Abstract:
A redirection of a URL page request may be performed by monitoring an upstream path from a subscriber to the internet through an ISP. When a URL page request is detected from a subscriber for whom a redirection is required, a redirection device generates a single TCP packet response that mimics a response from the intended destination server. The single TCP packet includes a set FIN bit that closes any active session with the destination server to prevent the subscriber from accepting packets from the destination server.
Method And Apparatus For Providing Network Access Control Using A Domain Name System
US Patent:
6256671, Jul 3, 2001
Filed:
Jun 24, 1998
Appl. No.:
9/104462
Inventors:

Assignee:
Nortel Networks Limited - Montreal
International Classification:
G06F 1516, G06F 1214
US Classification:
709227
Abstract:
A method and apparatus for providing network access control by manipulating a domain name system includes receiving, from a source, a request for an address which corresponds to a host name. A check is made as to whether a requestor corresponding to the request is allowed to access a host system corresponding to the host name. If the requestor is not allowed to access the host system corresponding to the host name, then an indication is provided to the source of the request that the address which corresponds to the host name cannot be located.
Modifying Message Size Indications In Communications Over Data Networks
US Patent:
6973097, Dec 6, 2005

Assignee:
Nortel Networks Limited - St. Laurent
International Classification:
H04J003/16
US Classification:
370470, 37039552
Abstract:
A communications system includes a data network that is coupled to an access system, which enables access to the data network by a client system. The client system issues requests through a router and the access system, with the requests specifying a server system as the destination. The server system sends response messages back to the client system through the data network and the router. The router is capable of modifying an indication of the maximum size of at least a portion of a message. This ensures that response messages communicated by the server system are not too large that the access system is unable to handle the response messages.
System And Method For Set-Top-Box Messaging Display

Assignee:
PerfTech, Inc. - San Antonio TX
International Classification:
H04N 7/025, H04N 7/16
US Classification:
725 32, 725153
Abstract:
In a set-top-box system, messages from a service provider are stored and delayed until activity from a set-top-box remote is detected. Messages are then generated and provided to a television associated with the set-top-box. Delaying of the message display until set-top-box activity is detected allows short display times, thus preventing burn-in on some television screens, while providing a greater likelihood that messages will be viewed.

Abstract:
A communications system includes a first network that includes a plurality of entities and a router. The router includes a network address translator. A node is capable of communicating data units with entities in the first network. Each data unit includes security information, such as information according to the Internet Security Association and Key Management protocol (ISAKMP) and the Encapsulating Security Payload (ESP) protocol. The network address translator is adapted to convert a destination address in a received data unit from the node to an address of one of the entities based on the security information in the received data unit.
