Abstract: Disclosed is an apparatus and method for segment routing using a remote forwarding adjacency identifier. In one embodiment, a first node in a network receives a packet, wherein the packet is received with a first segment-ID and another segment ID attached thereto. The first node detaches the first and the other segment IDs from the packet. Then the first node attaches a first label to the packet. Eventually, the first node forwards the packet with the attached first label directly to a second node in the network. In one embodiment, the other segment ID corresponds to a forwarding adjacency or tunnel label switched path between the first node and another node.

Abstract: Presented herein are techniques performed in a network comprising a plurality of network nodes each configured to apply one or more service functions to traffic that passes the respective network nodes in a service path. At a network node, an indication is received of a failure or degradation of one or more service functions or applications applied to traffic at the network node. Data descriptive of the failure or degradation is generated. A previous service hop network node at which a service function or application was applied to traffic in the service path is determined. The data descriptive of the failure or degradation is communicated to the previous service hop network node.

Abstract: A method for resolving split conditions in a port-extended network comprises receiving first information indicative of a first MAC address of a first controller on a first fabric link and second information indicative of a second MAC address of a second controller on a second fabric link. The method may also include determining that the first MAC address differs from the second MAC address and responsively determining that one of the first MAC address or the second MAC address was previously associated with a primary controller of the port-extended network. One of the first controller or the second controller is designated as the primary controller of the port-extended network based on the determination that one of the first MAC address or the second MAC address was previously associated with the primary controller.

Abstract: A method enabling symmetric routing between a first host within a first AS and a second host within a second AS is disclosed. The method includes detecting that a first routing message was received at an edge router of the first AS from an edge router of the second AS. The first message identifies the second host as a source and the first host as a destination of a forward route. The method further includes determining that the first message further comprises an indication to implement symmetric routing between the first and second hosts and generating a second routing message for propagating to router(s) within the first AS. The second message identifies the first host as a source and the second host as a destination of a return route, and indicates that data is to be sent via the edge router of the first AS that received the first message.

Abstract: In one embodiment, a network controller receives data indicative of one or more traffic requirements for network traffic. The network controller maps the data indicative of the one or more traffic requirements into a network policy. The network controller causes installation of the network policy onto one or more networking devices. The one or more networking devices are configured to route the network traffic based on the network policy. The network controller receives feedback regarding the installed network policy. The network controller adjusts the network policy based on the received feedback.

Abstract: Internet protocol addressing to uniquely identify clients and destinations across computer networks is provided. Communication between a proxy service and a DNS nameserver is facilitated to permit the DNS nameserver to send a subscriber identifier to the proxy service in response to a DNS request for a flagged domain name. The proxy service selects a unique IP address from a pool of IP addresses assigned to the proxy service. The proxy service associates the selected IP address with the subscriber identifier and optionally, the target domain name of the DNS request. The proxy service provides the unique IP address to the DNS nameserver which returns the unique IP address to the client device for the target domain name. The subscriber can then be authenticated at the proxy service transparently without input from the subscriber or client device based on the unique IP address provided by the client device to the proxy service.

Abstract: Information describing a rule to be applied to a traffic stream is received at an edge network device. The traffic stream is received at the edge network device. A preliminary data analysis of the traffic stream is performed at the edge network device in accordance with the rule. A determination is made that further analysis of the traffic stream should be performed from a result of the preliminary analysis. The traffic stream data is sent to another network device for further analysis.

Abstract: Systems and methods for providing host-neutral small cells include communicating with a first User Equipment (UE) at a small cell. The first UE communicates with the small cell via a first Evolved Node B (eNodeB) base station associated with a first Evolved Packet Core (EPC). The small cell further communicates with a second UE. The second UE communicates with the small cell via a second eNodeB base station associated with a second EPC. Although a different wireless carrier may be associated with each of the first and second UEs, they may both communicate with the host-neutral small cell.

Abstract: Systems, methods, and computer-readable media are provided for enforcing policy for upstream (e.g., traffic from an endpoint to the physical network layer or hardware fabric of a data center) flood traffic (e.g., broadcast, unknown unicast, or multicast traffic) originating from a virtual endpoint via a network fabric. In one embodiment, upstream flood traffic can be transmitted using a special multicast group to which only elements of the data center fabric (e.g., physical switches, routers) are subscribed. That is, upstream flood traffic is assigned to the special multicast group, resulting in unintended endpoints not receiving the flood traffic. However, the hardware fabric receives the flood traffic and will then enforce applicable policies to route the packets to intended endpoints.

Abstract: In response to receiving a probe request from a mobile client, an access point determines whether it should suppress a probe response. The access point receives a probe request from a wireless client device, and prepares a probe response to respond to the probe request. The access point determines whether the wireless client device is likely to associate with the wireless access point. Responsive to a determination that the wireless client device is unlikely to associate with the wireless access point, the access point suppresses the transmission of the probe response.

Abstract: One embodiment provides a system that facilitates efficient packet forwarding. During operation, the system stores, in a storage device in a first node, a static dictionary comprising a mapping between a type and length (TL) string and a compressed replacement string. In response to identifying the TL string in a packet, the system replaces the TL string with the compressed replacement string and transmits the packet to a second node, which stores the static dictionary in a local storage device, thereby facilitating compression of a TL string.
