Abstract: The present invention relates to systems and methods for network labeling in order to enhance real time data transfers. A network for a real time data transfer is identified and predictive models for network performance are compared against to determine if the network is suitable for the data transfer. If so, then the real time data transfer may be completed as expected. However, if the network is predicted to be unsuitable for transmission an alternate means for connection may be suggested. The alternate suggestion may include delaying the data transfer until the network is expected to be in better conditions, connecting to another access point in the network, or switching to another network entirely. During the data transfer, the quality of the network is monitored in order to update the predictive models for the network's quality. Identifiers for the network may be utilized to keep track of the networks.

Abstract: A STP n-node VLT system includes a first VLT device with a first virtual port, and a second VLT device with a LAG port, a non-LAG port, and a second virtual port coupled to the first virtual port. A STP engine designates the first VLT device as a root bridge and, in response, designates the first virtual port a designated port and the second virtual port a root port. The STP engine then designates a networking device coupled to the LAG port as the root bridge based on it having a higher priority than the first VLT device. Then STP engine then determines that a non-LAG link between the networking device and the second VLT device has caused the redesignation of the second virtual port as an alternate port and the non-LAG port as a root port, and swaps the designations of the second virtual port and the non-LAG port.

Abstract: A method and system for processing spanning tree protocol (STP) state in a multichassis link aggregation (MLAG) domain. More specifically, a pair of MLAG peers in the MLAG domain receive and transmit bridge protocol data units (BPDUs) in order to update a spanning tree used to implement the STP. The pair of MLAG peers includes an active MLAG peer and a standby MLAG peer operatively connected via a MLAG peer link. Further, processing of STP state towards updating the spanning tree is held accountable by the active MLAG peer until it experiences failover, after which responsibility for processing the STP state transfers to the standby MLAG peer. Duplicate BPDUs received by the MLAG domain are tracked to refresh a retention period for the STP state retained by the MLAG domain, and thus, prevent the premature discarding of STP state.

Abstract: Techniques are described for reusing downstream-assigned labels when establishing a new instance of a label switched path (LSP) prior to tearing down an existing instance of the LSP using make-before-break (MBB) procedures for RSVP. The techniques enable a routing engine of any non-ingress router along a path of the new LSP instance to reuse a previously allocated label for the existing LSP instance as the downstream assigned label for the new LSP instance when the paths of the existing LSP instance and the new LSP instance overlap. In this way, the non-ingress router does not need to update a label route in its forwarding plane for the reused label. When the new LSP instance completely overlaps the existing LSP instance, an ingress router of the LSP may avoid updating an ingress route in its forwarding plane for applications that use the LSP.

Abstract: Methods, apparatuses and systems directed to a distributed bootstrapping mechanism for peer-to-peer networks. In particular implementations, the de-centralized bootstrapping mechanism utilizes an allocated set of anycast addresses from the public IP space. Routing nodes or peer nodes corresponding to respective autonomous systems select an anycast address by computing a hash of an Autonomous System (AS) number (or other string) and mapping the hash value, or a portion of the hash value, to one of the anycast addresses in the allocated set. Other mechanisms for selecting anycast addresses (such as random selection) can be used. One or more of the routing nodes of the autonomous system may advertise a host route identifying the selected anycast address. When a new peer node is added to the P2P network, it may, upon initialization, transmit discovery messages using the anycast addresses from the allocated set, which may be ultimately routed to one of the peers in the P2P network.

The PIM relay mode enables the network switch device to receive a PIM control message, i.e., a PIM join and/or prune request, for a multicast group on a downstream port of the network switch device associated with a virtual L2 network instance, determine an upstream neighbor port of the network switch device associated with the instance, and relay the PIM control message on the upstream neighbor port of the network switch device without flooding the PIM control message on all ports of the switch device associated with the instance. In the PIM relay mode, the network switch device avoids triggering join suppression in downstream PIM neighbor devices with receivers, and avoids maintaining upstream states and setting a PIM periodic message timer.
