Private ethernet overlay networks over a shared ethernet in a virtual environment


A system for private networking within a virtual infrastructure is presented. The system includes a virtual machine (vm) in a first host, the vm being associated with a first virtual network interface card (vnic), a second vm in a second host, the second vm being associated with a second vnic, the first and second vnics being members of a fenced group of computers that have exclusive direct access to a private virtual network, wherein vnics outside the fenced group do not have direct access to packets on the private virtual network, a filter in the first host that encapsulates a packet sent on the private virtual network from the first vnic, the encapsulation adding to the packet a new header and a fence identifier for the fenced group, and a second filter in the second host that de-encapsulates the packet to extract the new header and the fence identifier..

Methods, systems and the interconnection of fibre channel over ethernet devices using a fibre channel over ethernet interconnection apparatus controller


Methods, apparatus and systems are provided for forwarding fibre channel initialization protocol (fip) and fibre channel over ethernet (fcoe) frames by a fcoe device interconnection apparatus (fia) and a fibre channel over ethernet device interconnection apparatus controller (fiac). In one aspect of the invention, a command is sent from a fiac to the fia to set the frame processing apparatus to identify received fip frames, which are forwarded with the original destination and source ethernet media access control (mac) addresses.

Distributed service chaining in a network environment


An example method for distributed service chaining in a network environment is provided and includes receiving a packet belonging to a service chain in a distributed virtual switch (dvs) network environment, wherein the packet includes a network service header (nsh) indicating a service path identifier identifying the service chain and a location of the packet on the service chain, evaluating a service forwarding table to determine a next service node based on the service path identifier and the location, with a plurality of different forwarding tables distributed across the dvs at a corresponding plurality of virtual ethernet modules (vems) associated with respective service nodes in the service chain, and forwarding the packet to the next service node, with substantially all services in the service chain provided sequentially to the packet in a single service loop on a service overlay.. .

Hardware implemented ethernet multiple tuple filter system and method


A filter in a docsis bridge performs ip filtering of incoming ethernet packets in hardware. The filter includes a parser circuit which, in hardware, parses each of the incoming ethernet packets and then utilizes the parsed information in combination with a content-addressable memory (cam) that stores filtering information, to filter and route the incoming ethernet packets.

Automatic discovery and enforcement of service level agreement settings


A method of automatically detecting the service level agreement settings in an ethernet virtual circuit (evc) carrying user packets comprises generating synthetic packets different from the user packets, on a data path in the evc at a level sufficiently high to saturate the evc. This accelerates the detection of actual effective values for the committed information rate (cir) and the excess information rate (eir) by triggering traffic shaping devices in the data path to enforce the cir and eir settings configured for those devices.
