Route reflector optimizations for interconnecting MPLS-based L3-VPN and L3-EVPN networks

Abstract: Methods and systems are described for providing route advertisements to provider edge devices on virtual private networks implemented using different protocols. An illustrative method includes receiving, from a first provider edge device on a first virtual private network (VPN), a route advertisement in a first format, wherein the first format corresponds to a first standard, determining whether the first format is translatable to a second format, wherein the second format corresponds to a second standard, in response to determining that the first format is translatable to the second format, identifying parameters for translating a route included in the route advertisement from the first format into the second format, generating a translated route advertisement by translating the route included in the route advertisement in accordance with the identified parameters, and transmitting, to a second provider edge device on a second VPN, the translated route advertisement including the translated route.

Systems with electrical isolation between signal and power domains

Abstract: The system includes power-over-ethernet (PoE) sockets that interface to dedicated power and signal printed circuit boards. More particularly, the system separates power transmission circuitry from signal transmission circuitry for PoE arrays of RJ-45 sockets. The sockets include pins of different length to accommodate a stacked configuration of the power board and signal board. The pins corresponding to higher-voltage powers are a different length than lower-voltage signal pins. More than one PoE connector array may be coupled to a stack printed circuit boards, with pins of varying length, configured to engage with respective boards of the stack. The boards of the stack may be electrically isolated from each other, although the boards may be structurally engaged with each other.

Method and system for spanning tree protocol role protection

Abstract: In general, embodiments of the invention relate to configuring network elements to prevent the formation of logical loops in a network More specifically, embodiments of the invention provide a mechanism to associate a port policy with all or a portion of the ports of a network element and to enforce certain types of behavior

Network recovery systems and methods

Abstract: A first network device is configured with a rule preventing network traffic from travelling from the first network device to one or more other network devices. The first network device is configured to receive and distribute network traffic to the one or more other network devices. A second network device receives and distributes network traffic to the one or more other network devices. The first network device determines that the second network device has failed. In response to determining that the second network device has failed, the first network device removes the rule so that the first network device receives and distributes network traffic to the one or more other network devices.

Reversible louver for fabric card fan solution

Abstract: A system may include a fan module and a louver. The fan module includes a first housing, adapted to include a fan in a first orientation. The fan is adapted to cause air to flow into the rear side of the first housing and out of the front side of the first housing. The fan module also includes a key receptacle that is adapted to mate with a first key. The louver includes a second housing that includes a set of slats adapted as a one way valve. The second housing also includes the first key which is adapted to only mate with the key receptacle. The second housing also includes the second key which is adapted to not mate with the key receptacle.
