Abstract: This technology enables a dynamic host configuration protocol (“DHCP”) Layer 2 relay in a Virtual Extensible Local Area Network (“VXLAN”) overlay fabric. A host device broadcasts a configuration request, such as a DHCP discover, across an Ethernet virtual private network (“EVPN”) overlay fabric. The DHCP discover is intercepted by a VXLAN Tunnel End Point (“VTEP”) device with Layer 2 bridging functionality. The VTEP device selects a centralized gateway (“CGW”) device with Layer 3 relay functionality as a destination for the DHCP discover. The VTEP device encapsulates the DHCP discover with a unicast VXLAN header comprising the media access control (“MAC”) address of the CGW device and transmits the encapsulated DHCP discover to the CGW device, resolving the destination address associated with the broadcast. The CGW device transmits the DHCP discover to an Internet Protocol (“IP”) address associated with a DHCP server that is external to the EVPN overlay fabric.

The nodes that are unreachable, or untraversed, may be flagged as suitable entry point candidates. In some embodiments, the flagged suitable entry point candidates may be reconciled with already known entry points included in the one or more tables.

Abstract: Communication between a source device and one or more pairs of accessory devices and between accessory devices within pairs of accessory devices is scheduled using slot availability masks (SAMs). A primary accessory device provides to the source device information about requirements for communication between the primary accessory device and a secondary accessory device. The source device determines a SAM map that specifies a periodic cycle of time slots, with time slots marked as available or unavailable for transmission and/or reception. The SAM map satisfies requirements to avoid collisions between communication between the source device and the accessory devices and communication between accessory devices within pairs of accessory devices. When multiple pairs of accessory devices establish connections with the source device, internal communication between accessory devices within pairs of accessory devices are aligned to use at least a common overlapping set of time slots.

Abstract: Techniques are described for inter-domain segment routing using transport endpoint segments. A transport endpoint segment provisioned on a router within a domain represents any intra-domain tunnel originated at the router and having reachability to an indicated endpoint within the same domain. The provisioning router advertises a transport endpoint segment identifier (TESID) for the transport endpoint segment to other routers or a controller for use in segment routing. The TESID for the transport endpoint segment remains constant regardless of which intra-domain tunnel is bound to the transport endpoint segment. The provisioning router dynamically binds the transport endpoint segment to at least one intra-domain tunnel, and any changes to the bound intra-domain tunnel are updated locally at the provisioning router. In this way, an inter-domain segment routing tunnel may be constructed as a list TESIDs that are not affected by intra-domain tunnel changes.

Abstract: Implementations provide automated intrusion alert-based blacklisting with minimal false positives that ignores regular business operations, scalable to accommodate the volume of IDS alerts received by high-traffic internet-accessible networked systems. Implementations identify and block hostile infrastructure IP addresses during the reconnaissance phase based on IDS alert(s). Each IDS alert is automatically reviewed in historical context and triggers IP blocking as necessary. Some implementations maintain TCP/IP handshake records, preventing blocking an IP used to conduct regular business operations on the network that a malicious party has spoofed to avoid identification. Based on the historical context of each IP address within the local network environment, specifically regular business operations traffic versus malicious traffic, the IP address is blocked only if the majority of connections therefrom are malicious.
