Abstract: Provided herein are protective masks made with polymer-based materials and methods of forming the materials. Methods of forming the interlaced polymer-based materials comprise applying adhesive to a substrate, electrospinning a first polymer solution onto the substrate from a first group of spinning electrodes, electrospinning a second polymer solution onto the substrate from a second group of spinning electrodes, and applying hot air to dry the polymer-based materials electrospun from the first polymer solution and the second polymer solution to form the interlaced polymer-based materials.

Abstract: Coexistence and migration of legacy and VXLAN networks may be provided. A first anchor leaf switch and a second anchor leaf switch may detect that they can reach each other over a Virtual Extensible Local Area Network (VXLAN) overlay layer 2 network. In response to detecting that they can reach each other over the VXLAN, the second anchor leaf switch may block VLANs mapped to the VXLAN's VXLAN Network Identifier (VNI) on the second anchor leaf switch's ports connecting to spine routers. In addition, the first anchor leaf switch and the second anchor leaf switch may detect that they can reach each other over a physical layer 2 network. In response to detecting that they can reach each other over a physical layer 2 network, the second anchor leaf switch may block Virtual Extensible Local Area Network (VXLAN) segments at the second anchor leaf switch.

Abstract: A method is provided in one example embodiment and includes acquiring at a local network element information regarding a remote network element via a control protocol distribution method and refraining from instantiating the remote VTEP for the remote network element on the local network element until unicast traffic from the local network element to the remote network element via an overlay network has begun. The method may further include detecting unicast traffic from the local network element to the remote network element and subsequent to the detecting, instantiating the remote VTEP for the remote network element on the local network element. Some embodiments may include detecting cessation of the unicast traffic from the local network element to the remote network element and subsequent to the detecting cessation, uninstantiating the remote VTEP for the remote network element from the local network element.
