Abstract: The disclosure provides various embodiments of systems and methods of generating a heartbeat in an HVAC system and networks. In an embodiment, a method includes a heartbeat message being sent by a first subnet controller upon the first subnet controller taking active control of a subnet of the HVAC network.

Abstract: In one embodiment, a network device may have its network interfaces identified as either network-to-network interfaces (NNIs) configured to communicate with other network devices in a first computer network, or user-to-network interfaces (UNIs) configured to provide service to the first computer network for user devices. Based on determining at least one NNI for forwarding upstream traffic to an aggregation device of the first network that connects the first network to a second network, any NNI that is not used for forwarding upstream traffic is deemed a novel “NNI alternate” (NNI-ALT). The forwarding of traffic at the network device may be controlled to provide user isolation between network devices by denying traffic forwarding between UNIs and NNI-ALTs as well as between NNI-ALTs and NNI-ALTs, while permitting traffic forwarding between NNIs and NNI-ALTs.

Abstract: A packet switch contains a link state group manager that forms supergroups from multiple link aggregations. The link state group manager collects state information for the link aggregations in a supergroup, and uses state criteria to determine whether the link aggregations are allowed to be up, as a supergroup, for data traffic. This allows a supergroup of links to only come up when it meets a minimum performance criteria, with traffic routed around the supergroup when the supergroup cannot meet the minimum performance criteria, even if some link aggregations in the group are functional.

Abstract: Some embodiments provide different frameworks that implement conflict avoidance systems and methods for ensuring uniqueness in identifying assets for different customers that are deployed to server capacity of one or more distributed platforms participating in a federation. Specifically, different frameworks are provided whereby the distributed platforms authorize use of a domain before configuring the domain to identify assets of a customer. A method performed in one such framework includes receiving a domain that is specified for identifying assets of a first customer belonging to a first distributed platform of the federation. The method determines whether the domain conflicts with a domain that is configured by a second distributed platform of the federation. The method then communicates with the first distributed platform (i) to configure the received domain when there is no conflict and (ii) to prevent the first distributed platform from configuring the received domain when there is a conflict.

Abstract: Supporting virtual private networks by using a new layer 3 address to encapsulate a network-bound packet so that its context information, from which a layer 2 (e.g., MAC) address can be derived, is preserved. If this encapsulation was not done, the layer 2 address would change over each segment of the network. Thus, the encapsulation preserves the concept of group identification, using at least a part of the context, over the entire network and not just at the edge of the network. If a packet is received from the network (to be forwarded to a customer), the layer 3 address that was added in the encapsulation is stripped off. The original layer 3 destination address may be used with a client device addressing table to determine a new context information, and a layer 2 (e.g., MAC) address of a destination client device.

Abstract: Routes may be installed across multiple link state protocol controlled Ethernet network areas by causing ABBs to leak I-SID information advertised by BEBs a L1 network area into an L2 network area. ABBs will only leak I-SIDs for BEBs where it is the closest ABB for that BEB. Where another ABB on the L2 network also leaks the same I-SID into the L2 network area from another L1 network area, the I-SID is of multi-area interest. ABBs will advertise I-SIDs that are common to the L1 and L2 networks back into their respective L1 network. Within each L1 and L2 network area, forwarding state will be installed between network elements advertising common interest in an ISID, so that multi-area paths may be created to span the L1/L2/L1 network areas. ABBs may summarize BEB multicast trees such that the set of trees for a given I-SID transiting the ABB is condensed into a common tree.

Abstract: The present application presents systems and methods for handling by an HTTP virtual server (HTTPVS), connections via which non-HTTP data is transmitted between clients and servers. HTTPVS intercepts a request from a client to establish first transport layer connection (TLC) with a server. HTTPVS establishes second TLC with the servers in response to receiving an acknowledgment from a client to establish the first TLC. HTTPVS determines if a first network packet transmitted via first TLC comprises an HTTP payload or non-HTTP payload. If HTTPVP the first network packet includes HTTP payload, HTTPVS may process all transmissions from the first TLC in accordance with connection tracking and forward the processed transmissions to the server via the second TLC. If HTTPVS determines that the first network packet does not include an HTTP payload, HTTPVS may link the first TLC and the second TLC so the client and server exchange non-HTTP communication without interruption.

Abstract: Media, methods and systems are provided for coordinating changes of network sources for media streams in a telecommunications network. The streams communicate instances of media content via packets to devices. A first network source streams packets of an instance of media content to a device. Each packet includes information regarding the temporal ordering of that packet within the instance and information regarding the sequencing of the packet within the stream. It is determined that a second network source should stream the instance of media content. A point in the temporal ordering within the instance is identified and communicated at which the second network source will provide the instance of media content. The second network source streams to the mobile device the instance of media content from the identified point, without requiring adjustment of the information regarding the sequencing of the packets within the stream.

Abstract: In one embodiment, in response to receiving a topology change notification at a network bridge having ports identified as either a network port or an edge port, address learning may be disabled on the network bridge. Once address learning is disabled, an association of all entries of a forwarding table of the network bridge having addresses previously forwarded on a particular network port of the network bridge may be changed to forward those addresses on all network ports of the network bridge (e.g., flooding the frames not addressed to edge ports on all network ports only). Subsequently, address learning may be enabled on the network bridge, thus repopulating the network port entries of the forwarding table in response to the topology change.

Abstract: A solution for the Network Address Translation (NAT) traversal problem for Real Time Protocol (RTP) is provided, which uses an RTP Proxy (e.g., a Session Border Controller (SBC)), instead of being logically located between the NAT and the Feature Server (FS), but instead, for devices which use a protocol unsupported by the SBC, having these devices first signal the Feature Server, which determines whether and how an RTP proxy should be invoked. An RTP proxy should be invoked by the FS if Both endpoints (e.g., devices) are behind different NATs (or one of the endpoints is behind a NAT and the other is not) and neither of the endpoints are already signaled through an RTP proxy. For example, the SBC is interposed (at least logically) between the Feature Server and other shared components.
