Auto-discovery of all the
network, compute and

Network
discovery
Deduce
topology
Auto-construction of
network topology based on
what is discovered/ updated
on the network
Validate
topology
Validate the discovered network topology against
desired for compliance and design conformance
Hosts
4. Discovery engine uses host records in AD, queries
the host objects and stiches the information, with
that obtained via SNMP discovery to construe the
complete topology of the network...

Directory
1. User provides a set
of seed devices and
credentials

2. Discovery engine connects to the
seed devices using SNMP and uses
other information out of MAC, ARP,
Route and LLDP tables…
3. Discovery engine, traverses the
devices connected to the seed
devices and there on….

Granular controls required
for troubleshooting
Design the IP addressing properties,
VLANs, routes, ACLs, LAGs, port
channels, policies…

Configuring fabric network of datacenter
for dynamic assignment of IP addresses
and network properties to the compute
resources
• Configure the DHCP
scopes for the specified IP
subnets and IP pools
Setup of MS DHCP
•

•
Setup to configure
Access switch
Set mgmt. IP on an Ethernet port
Set mgmt. username and password
Get and set default VLAN
Set DhcpHelper IP address
Assumption:
Switch already bootstrapped with the required firmware
• Configure VLANs (IDs, state, VLAN IP
addrs description)
addr., dhcpHelper IP addrs.,
• Configure Ethernet port (VLANs,
dhcpHelpers port addr., VLAN mode,
dhcpHelpers,
speed, max speed, state, network addr.,
portlacpsetting, descriptions)
Configuration of
access switch
Assumption:
Admin will be upfront aware about the port he is
intending to configure
1. Accurately measure loss/latency
within and across fault domains
5. Insight to granular device/port level
statistics and network monitoring data.
These will be available via REST
APIs and out of SCOM for
further diagnostics /
remediation
Measure
Remediation
4. Determine which virtual networks
are impacted by the degradation

localization
(root cause)
2. Detect network outages
in near real time
3. Determine which device/interface is
causing network degradation
inter-subnet
intra-subnet
subnet-to-internet
Uses topology to autodiscover all possible
paths taken by network
packets
Uses advanced
algorithms to localize
problems to specific
nodes or even links
Supports ECMP networks (L2, L3, or a combination of
both L2 and L3 networks)

Centralized management across virtual/physical networks, including virtualized network services
Centralized configuration
Standardized APIs
Built from Azure’s experience in managing
large networks.
Enables development of management
apps, automation and customization via
extensible northbound & southbound
REST APIs.
•
Central point of automation/control
•
Scalable for large, dynamic networks.
Complete solution for private
clouds
Extensible, standards based
•
Leverage existing investments (Virtual
Network Functions)
•
Compatible with existing & emerging
network designs (SNMP, OVSDB,
VXLAN, OMI, …)
•
Hybrid / Remote connectivity
•
Cloud scale Load Balancer
•
Firewall
•
Management of physical network
Lower TCO
•
Active monitoring / diagnostics
•
Integrate with existing infrastructure
(VMM, OM, …)
•
Ease of network troubleshooting
Common control plane, reduced operational complexity
TerminationPoint
• Topology API contains three types of objects
• TopologyNode
• TopologyTerminationPoint
• TopologyLink
A network interface like
NIC, switch port, port
channel etc. on a network
device is represented by a
topology termination point
Router
• TopologyNode represents a network devices
• Each network interface of the device is
represented by a topology termination point
object.
TopologyNode
A network device like a
switch router or host is
represented by a topology
node
Switch 2
Switch 1
TopologyLink
Connection between two
devices is represented by a
topology link
• Topology links represent the connections
between two network devices
