Geneve:generic Network Virtualization Encapsulation

Earlier this year, VMware, Microsoft, Red Hat and Intel published a IETF draft on Generic Network virtualization Encapsul ation (Geneve). This draft (first published on Valentine's Day no less) includes authors from the each of the first generation Encapsulati On Protocols-vxlan, NVGRE, and STT. However, beyond the obvious appeal of unification across hypervisor platforms, the salient feature of Geneve is that it WA s designed from the ground up to be

Comparing SFlow and NetFlow in a VSwitch

addition, exporting packet headers allows a sFlow analyzer to monitor all types of traffic flowing across the switch; Note the ARP and IPV6 traffic displayed in Sflowtrend in addition to the tcp/udp flows. Visibility into Layer 2 traffic are particularly important in switched environments where protocols such as DHCP/BOOTP, STP , LLDP and ARP need to be closely managed. SFlow also provides visibility into networked storage, including Ethernet SAN technologies (e.g. FCoE or AoE), that Typica Lly

Storage Network virtualization-was it the Northern Wilderness or the sub-desert? (1)

Network virtualization is now a hot topic, and major manufacturers are scrambling to grab this cake. Technologies involved include virtual Emulation for NICs, I/O pass-through, SR-IOV), virtual access technology for networks VN-Tag/VEPA), covering network switching VXLAN/NVGRE ), and Software Defined network SDN/OpenFlow. For details, refer to the blog "Network virtualization-ongoing network revolution" published by EMC China Research Institute, which
