Patent number: 8730977Abstract: The invention relates to the field of network communication in a wide area, where a local network of a first type has a sending station that communicates with a receiving station in a local network of a second type. A network of a third type is in between the two networks and provides virtual private networking between the two local networks. The network of the first type supports a fine grained QoS, whereas the network of the third type supports a coarser grained QoS. In one example the network of the first type is RSVP capable and the network of the second type is an MPLS network. The invention resides in a component called RSVP-MPLS proxy that maps the RSVP resource advertisements and reservations within an RSVP-aware customer network to an MPLS network, whereby the receiver side doesn't participate in the RSVP communication process.Type: GrantFiled: June 1, 2007Date of Patent: May 20, 2014Assignee: Thomson LicensingInventors: Eduard Siemens, Stefan Kubsch, Jens Brocke, Ralf Koehler, Andreas Matthias Aust, Frank Glaeser

Patent number: 8233407Abstract: After every bus reset operation in an IEEE 1394 network, the network is reconfigured. This involves a table with further station-specific information being created after the bus initialization phase, the tree structure identification phase and the self identification phase. Each network station returns its station-specific information to the requesting network station. In the first phase, all that information which has been received up to a time determined by a first abort criterion is sorted into the table. Next, the still incomplete table is enabled for use by an application program in the requesting network station. In the second phase, the still missing station-specific information is then requested again and is sorted into the table when it is delivered by the stations to which requests have been sent.Type: GrantFiled: June 16, 2005Date of Patent: July 31, 2012Assignee: Thomson LicensingInventors: Frank Glaeser, Ralf Koehler, Jens Brocke, Kurt Knuth

Patent number: 8185770Abstract: Modern computers (10, 20) come with different timers having different attributes like time resolution, supported time range and time reference. Some are local timers, representing relative time values like the TSC counter (11, 21) counting CPU cycles from the power on or reset of the computer. Some are global timers, representing an absolute or real time. Having different classes of timers in the computer (10, 20), a number of computations need to be performed to tie the different timers to each other. It is the idea of the invention to define a single high resolution timer structure wherein the time value is represented with a digital number and a flag clarifies whether the timer is a global timer or local timer. The invention enables a much faster processing of the time values. The global time, tied to a high-resolution timer can be tracked much faster. This means better precision of scheduling of time critical jobs, like packet scheduling for data transport.Type: GrantFiled: January 30, 2009Date of Patent: May 22, 2012Assignee: Tixel GmbHInventors: Eduard Siemens, Frank Glaeser, Jens Brocke, Stefan Kubsch, Ralf Koehler, Andreas Matthias Aust

Patent number: 8179793Abstract: The invention relates to a new type of quality of service architecture for a network assembly and a corresponding computer network system. The Internet technology as approved by the IETF organization has defined different services. One is the integrated services (IntServ) and the other the differentiated services (DiffServ) architecture. Another is the RSVP Protocol according to which Quality of Service can be implemented with accuracy and richer functionality. The invention shows a way how less sophisticated QoS managers inside the network with only DiffServ or Intserv capability, can be used for enhancing the QoS functionality based on so-called RSVP shadowing messages, and easy to implement RSVP shadowing stacks.Type: GrantFiled: June 30, 2009Date of Patent: May 15, 2012Assignee: Thomson LicensingInventors: Jens Brocke, Andreas Matthias Aust, Frank Glaeser, Ralf Koehler, Stefan Kubsch, Eduard Siemens

Patent number: 8127003Abstract: A method of operating a network subnet manager, in particular Infiniband network subnet manager in a subnet of a network. Only one subnet manager entity can be master within a subnet. A problem related with this specification is that a specific vendor implementation may exist with many features and internal functionality that are not specified in the network specification. If such a subnet manager loses its exclusivity because another subnet manager enters the subnet, having higher priority, the additional features from the vendor implementation can no longer be used in the subnet. The proposed method solves this problem by allowing a subnet manager that has a lower hierarchy level and thus lower priority to maintain its managing operation by becoming the master subnet manager again.Type: GrantFiled: November 19, 2009Date of Patent: February 28, 2012Assignee: Thomson LicensingInventors: Frank Glaeser, Andreas Matthias Aust, Jens Brocke, Eduard Siemens, Ralf Koehler, Stefan Kubsch

Publication number: 20110099178Abstract: After every bus reset operation in an IEEE 1394 network, the network is reconfigured. This involves a table with further station-specific information being created after the bus initialization phase, the tree structure identification phase and the self identification phase. This is done by making requests to the individual network stations. Each network station returns its station-specific information to the requesting network station. It has become apparent that in some cases a response from the network station to which a request has been sent is returned only after the request has been repeated a plurality of times or in the extreme case even not at all. So as not to delay the creation of the network node information table unnecessarily for such cases, the invention proposes creating the table in two phases. In the first phase, all that information which has been received up to a time determined by a first abort criterion is sorted into the table.Type: ApplicationFiled: June 16, 2005Publication date: April 28, 2011Inventors: Frank Glaeser, Ralf Koehler, Jens Brocke, Kurt Knuth

Patent number: 7920565Abstract: When updating a data record identified by a version number, the problem exists that a simple not equal to comparison or greater than comparison is often insufficient for ascertaining the up-to-date nature of the newly received data record, particularly if the data record is transmitted to a receiving station via an unsecured data link and the version number originates from a limited range which is repeatedly run through periodically. The invention solves the problem by virtue of the fact that it divides the range of values of the version number into the ranges “old” and “new”, on the basis of the current value of a version number. The periodicity with which the range of values is run through is taken into account in this case, however. That is to say that the range “old” or the range “new” may perfectly well include the jump from the highest value in the range of values to the lowest value in the range of values.Type: GrantFiled: November 15, 2006Date of Patent: April 5, 2011Assignee: Thomason LicensingInventors: Jens Brocke, Andreas Aust, Frank Glaeser, Ralf Koehler

Patent number: 7801053Abstract: The invention relates to a method for setting consistent values for a parameter in a network of distributed stations (10 to 14), and to a corresponding network subscriber station. In certain circumstances, it has been found that inconsistent entries can occur for the gap count parameter on the local bus in an IEEE 1394 network. If the bus management instance (25, 26) relies on the automatic behavior, as provided in the Standard, of all the network subscriber stations (10 to 11) to automatically set the maximum value of 63 after the second bus resetting process without any intermediate resetting of this parameter, this can lead to progressive resetting of the network, and this can result in blocking of the network. The problem is solved by immediate transmission of a parameter setting message for the critical network parameter once an inconsistency has been found.Type: GrantFiled: May 19, 2004Date of Patent: September 21, 2010Assignee: Thomson LicensingInventors: Jens Brocke, Frank Gläser, Ralf Köhler, Kurt Knuth
