Appl. No.:

11/400695

Inventors:

Paul Quinn - San Francisco CA, US
Kenneth Durazzo - San Ramon CA, US
Darrel Lewis - San Francisco CA, US
Barry Raveendran Greene - Cupertino CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 12/28
H04L 12/56

US Classification:

37039543, 370389, 370392, 37039521, 370471, 370473

Abstract:

A system for selectively applying a service to a packet in a network. In a specific embodiment, the system includes a mechanism for encoding service information in a network-compatible packet header and providing encoded data in response thereto. In a more specific embodiment, the network-compatible header includes a Multi-Protocol Label Switching (MPLS) header, a Generic Route Encapsulation (GRE) header, and/or a Layer-2 Tunneling Protocol (L2TP) header.

International Classification:

G06F 11/00

US Classification:

726 23

Abstract:

A method includes monitoring outgoing request packets transmitted by a node in a protected network over a link connecting the protected network to an external network. Incoming response packets that originate in the external network and are destined for transmission to the node are also monitored. One or more of the incoming response packets that were not solicited by any of the outgoing request packets are identified responsively to monitoring the outgoing request packets and the incoming response packets.A characteristic that differentiates between the identified incoming response packets and the incoming response packets that were solicited by the outgoing request packets is determined. A guard device in the external network is instructed to inhibit the transmission over the link of subsequent unsolicited response packets based on the characteristic.

International Classification:

H04L 29/12
H04L 12/741
H04L 12/751

Abstract:

A method is provided in one example embodiment and includes detecting by a first network element at a first data center site a local connection of an endpoint identifier (“EID”), in which the EID was previously locally connected to a second network element at a second data center site and notifying a mapping server of the local connection of the EID to the first network element. The method further includes receiving from the mapping server identifying information for the second network element and communicating with the second network element using the identifying information to obtain service information for traffic associated with the EID. The method may also include applying a service identified by the service information to outgoing traffic from the EID as well as applying a service identified by the service information to incoming traffic for the EID.

International Classification:

H04L 29/06
H04L 12/741
H04L 29/12
H04L 12/46

Abstract:

Aspects of the embodiments are directed to systems, methods, and computer program products to program, via a northbound interface, a mapping between an endpoint identifier (EID) and a routing locator (RLOC) directly into a mapping database at a mapping system; receive, from a first tunneling router associated with a first virtual network, a mapping request to a second virtual network, the first router compliant with a Locator/ID Separation Protocol, the mapping request comprising an EID tuple that includes a source identifier and a destination identifier; identify an RLOC based, at least in part, on the destination identifier of the EID tuple from the mapping database; and transmit the RLOC to the first tunneling router implementing an high level policy that has been dynamically resolved into a state of the mapping database.
