Abstract: The present invention relates to a method of synthesizing copper (I) 5-nitrotetrazolate. The method involves a series of interconnected steps. Initially, a stock solution of sodium 5-nitrotetrazolate is prepared in water from 5-aminotetrazole nitrate, which is then preserved for later use in producing copper (I) 5-nitrotetrazolate thereby eliminating the need for immediate utilization. A nascent Copper (I) chloride is prepared separately. In a single step, the stock solution of sodium 5-nitrotetrazolate is coupled with the nascent copper (I) chloride, resulting in the formation of copper (I) 5-nitrotetrazolate.

Abstract: In one embodiment, an autonomous system border router (ASBR) advertises a same forwarding label for received advertised routes of a merging context that were advertised with a same forwarding label for the ASBR to use when sending corresponding packets. An ASBR receives via a routing protocol from a particular router in the same autonomous system, a plurality of same-labeled received routes advertised with a same first forwarding label within a merging context. In response to each of the plurality of same-labeled received routes having the same first forwarding label to use to forward packets to the particular router and being in the same merging context, the ASBR determines a merged forwarding label and advertises to a peer ASBR in another autonomous system (AS) each of the plurality of same-labeled received routes with the merged forwarding label for the peer ASBR to use to forward packets to the ASBR.

Abstract: In one embodiment, a method includes establishing in a Virtual Private Local Area Network (LAN) Service (VPLS) over Multi-Protocol Label Switching (MPLS) network a floating pseudowire between a first provider edge router and a redundancy group having a plurality of provider edge routers each configured to forward data toward a external device. Each provider edge router in the redundancy group is configured to maintain an active link to the external device. A provider edge router that is not a member of the redundancy group sends data directed to the external device through the floating pseudowire. Only one provider edge router in the redundancy group receives and forwards the particular data to the external device.

Abstract: A network data packet routing apparatus with BGP is configured to soft reset an AFI or SAFI, so that forwarding on routes associated with the AFI or SAFI can continue even after an event or error. One approach involves establishing a Border Gateway Protocol (BGP) peering session between a first node and a second node in a packet-switched network; detecting a BGP condition requiring a reset of a BGP address family indicator (AFI) data structure or a sub-address family indicator (SAFI) data structure, wherein the BGP condition does not affect states of routes in the AFI or SAFI; preserving a BGP state and a forwarding state of the AFI or SAFI; and forwarding data on routes represented in the AFI or SAFI. Soft notification messaging and marking routes as stale facilitates the approach.

Abstract translation: 具有BGP的网络数据分组路由设备被配置为软复位AFI或SAFI，使得即使在事件或错误之后，与AFI或SAFI相关联的路由上的转发也可以继续。 一种方法涉及在分组交换网络中的第一节点和第二节点之间建立边界网关协议（BGP）对等体会话; 检测需要复位BGP地址族指示符（AFI）数据结构或子地址族指示符（SAFI）数据结构的BGP条件，其中BGP条件不影响AFI或SAFI中的路由状态; 保持BGP状态和AFI或SAFI的转发状态; 并转发AFI或SAFI所代表的路由数据。 软通知消息和标记路由为陈旧方便。
