Abstract: A method implemented by a sending host implemented as a network element (NE) comprises receiving, by a receiver of the sending host, a set of locators from a distributed mapping system, each of the locators in the set of locators being an address associated with the receiving host, storing, in a memory of the sending host, the set of locators in an entry of a local identifier (ID)-to-locator database in association with an ID of the receiving host, transmitting, by a transmitter of the sending host, a plurality of packets to a plurality of endpoint routers (xTRs), each of the xTRs associated with each of the locators in the set of locators, and receiving, by the receiver of the sending host, a response from one of the xTRs in response to sending the plurality of packets to the plurality of xTRs, a locator associated with the one of the xTRs being an address of a current location of the receiving host.

Abstract: A method implemented by a network element (NE) configured as a temporal tunnel service (TTS) controller, comprising computing, via a processor of the NE, a path in a network for a temporal label switched path (LSP), wherein the path satisfies a constraint in a scheduled time interval comprising a predetermined start time and a predetermined end time, reserving, at a current time prior to the predetermined start time via the processor, a first network resource on a link along the path computed for the temporal LSP, wherein the first network resource is reserved for the temporal LSP to carry traffic in the scheduled time interval, and sending, at the predetermined start time via a transmitter of the NE, a LSP creation request to a node associated with the temporal LSP to request creation of the temporal LSP along the path in the network.

Abstract: The system and method of the present disclosure relates to technology for a network system supporting multiple topology transparent zones (TTZs) on an edge node. TTZs have a topology including TTZ nodes consisting of edge nodes and internal nodes connected together by internal links. The edge nodes may also be connected to external nodes outside of the TTZ. The edge node is responsible for generating and distributing link state advertisements (LSAs) to generate virtual paths from the edge node to other edge nodes in each of the TTZs. Each TTZ sharing the edge node and each external node neighboring one of the other edge nodes of the TTZs is virtualized by distribution of the LSAs. However, the internal topology of each TTZ is concealed from each of the other TTZs sharing the edge node and from any neighboring external node connected to one of the other edge nodes.

Abstract: Systems and methods for providing a session layer connection between two or more network endpoints. Session layer connections created and maintained using embodiments of the present disclosure use endpoint identifiers (EIDs) and allow for session layer continuity when a lower-layer connection is broken because of network failures or the movement of an endpoint from one network connection to another.
