Filed:

Jun 30, 1998

Appl. No.:

09/106449

Lev Volftsun - Herndon VA
Clay H. Neighbors - Reston VA
Fred R. Rednor - Arlington VA
Andrew West - Leesburg VA
Adrian Kingston - Sterling VA
Mikhail Rabinovitch - Herndon VA

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 1228

US Classification:

370352, 370465

Abstract:

An auxiliary communication network is introduced into a virtual private network for passing signaling messages that present features not supported by the public, primary communication network portion of the virtual private network. Protocol converters are positioned within the virtual private network to intercept signaling messages, establish a connection through the auxiliary network, determine whether the intercepted messages present unsupported features, and, in which case, route corresponding feature requested through the auxiliary communication network. Preferably, the auxiliary network connection is established in a direction reverse to and in response to the primary network connection.

International Classification:

H04L 29/12
G06F 40/242
G06F 40/247
G06F 40/284
G10L 15/05

Abstract:

A method can include receiving a string of characters. The method can include determining one or more possible word boundaries for words in the string of characters based at least partially on a segmentation process. The method can also include determining, for each character in the string of characters, an amount of time between entry of each character on an input device. The method can include determining, based at least partially on the amount of time and the one or more possible word boundaries, one or more actual word boundaries for the words in the string of characters. The method can also include outputting one or more determined words in the string of characters based at least partially on the one or more actual word boundaries.

International Classification:

H04L 29/12
G06F 17/30

Abstract:

Disclosed are techniques for ranking domain names for presentation to a user. The techniques include obtaining, over a computer network, domain name data including, for each of a plurality of training domain names, respective user information; generating, by at least one electronic processor, a model relating at least features of each of the plurality of training domain names to respective user features derived from the respective user information; obtaining novel user information for a novel user; obtaining a plurality of domain names; ranking the plurality of domain names, using the model and novel input data including novel user features derived from the novel user information, according to predicted domain name suitability for the novel user; and providing a ranked list of the plurality of domain names.

International Classification:

H04L 29/12

Abstract:

Systems and method for detecting domain name system (DNS) registrar collusion include a collusion detector at a registry. The collusion detector obtains information related to name acquisition requests submitted by DNS registrars attempting to acquire domain names in a drop pool of expired domain names and provides attempt sets containing the domain names targeted by the DNS registrars for acquisition. Each attempt set contains at least one targeted domain name that a respective DNS registrar attempted to acquire via at least one name acquisition request. The collusion detector determines a degree of similarity between two or more attempt sets corresponding to a pair of the DNS registrars, estimates a likelihood of collusion between the pair of DNS registrars based on the degree of similarity, and performs any mitigation action warranted by the likelihood of collusion.
