Appl. No.:

16/902078

Inventors:

- Santa Clara CA, US
Aparna Sushrut Karanjkar - Santa Clara CA, US
Nitin Ravindra Karkhanis - Santa Clara CA, US

International Classification:

H04W 28/08
H04W 40/24
H04W 99/00
H04W 48/18
H04W 76/10
H04L 12/743

Abstract:

A method and system for steering bidirectional network traffic to a same service device. Specifically, the disclosed method and system entail the maintaining and synchronization of link aggregation group (LAG) tables tied to a pair of LAG ports instantiated on a network element directly connected to a pair of peer linking service devices. Network traffic (i.e., MAC frames) arriving at the network element, from a first host and intended for a second host (e.g., indicative of a first direction of the network traffic), may be steered towards one of the pair of service devices based on hashing of information included in a received MAC frame in conjunction with the LAG table tied to the LAG port (of the pair of LAG ports) that which received the MAC frame.

International Classification:

H04L 12/761

Abstract:

A method and system for inspecting broadcast network traffic between end points residing within a same zone. Specifically, the method and system disclosed herein entail the provisioning of unique forward-service and reverse-service virtual network identifiers (VNIs), and corresponding virtual layer-2 (VL2) forward-service and reverse-service broadcast domains, respectively, to communications originating from and destined to intercept hosts.

Abstract:

A method and system for inspecting cross-zone network traffic between end points residing within different zones. Specifically, the method and system disclosed herein entail the provisioning of unique forward-service and reverse-service virtual network identifiers (VNIs), and corresponding virtual layer-2 (VL2) forward-service and reverse-service broadcast domains, respectively, to communications originating from and destined to intercept hosts.

Abstract:

A method and system for inspecting unicast network traffic between end points residing within a same zone. Specifically, the method and system disclosed herein entail the provisioning of unique forward-service and reverse-service virtual network identifiers (VNIs), and corresponding virtual layer-2 (VL2) forward-service and reverse-service broadcast domains, respectively, to communications originating from and destined to intercept hosts.

International Classification:

H04L 29/06
H04L 12/24
H04L 12/751
H04L 12/46

Abstract:

A method and system for steering network traffic towards a service device. Specifically, the disclosed method and system entail the installation of multiple service devices around a network. Service policies are cloned across the multiple service devices, and further, each service device is assigned common virtual routing and bridging addresses. Using at least these common virtual routing and bridging addresses, intercept virtual tunnel end points (VTEPs) redirect or bridge network traffic to a service device.

International Classification:

H04L 29/12

Abstract:

A system and method for host discovery and tracking in a network. Specifically, the disclosed system and method entail maintaining bindings pertinent to the mapping of any host in the network, by way of their host IP address, to a respective virtual tunnel end point (VTEP). More specifically, these bindings may include: (i) a host IP address to host MAC address binding or mapping; and (ii) a host MAC address to VTEP IP address binding or mapping. Further, these bindings may be especially significant towards directing network traffic to a host over virtual layer-3 (L3) protocols.
