Method Detail

setUpConnectivityInternetToHost

void setUpConnectivityInternetToHost(org.onlab.packet.IpAddress dstIpAddress)

Sets up connectivity for packet from Internet to a host in local SDN network.

Parameters:

dstIpAddress - IP address of destination host in local SDN network

setUpConnectivityHostToHost

void setUpConnectivityHostToHost(org.onlab.packet.IpAddress dstIpAddress,
                                 org.onlab.packet.IpAddress srcIpAddress,
                                 org.onlab.packet.MacAddress srcMacAddress,
                                 ConnectPoint srcConnectPoint)

Sets up the connectivity for two hosts in local SDN network.

Parameters:

dstIpAddress - the destination IP address

srcIpAddress - the source IP address

srcMacAddress - the source MAC address

srcConnectPoint - the connectPoint of the source host

setUpConnectivityHostToInternet

void setUpConnectivityHostToInternet(org.onlab.packet.IpAddress hostIp,
                                     org.onlab.packet.IpPrefix prefix,
                                     org.onlab.packet.IpAddress nextHopIpAddress)

Sets up connectivity for packet from a local host to the Internet.

Parameters:

hostIp - IP address of the local host

prefix - external IP prefix that the host is talking to

nextHopIpAddress - IP address of the next hop router for the prefix

updateExistingMp2pIntent

void updateExistingMp2pIntent(org.onlab.packet.IpPrefix ipPrefix,
                              ConnectPoint ingressConnectPoint)

Adds one new ingress connect point into ingress points of an existing intent and resubmits the new intent.

If there is already an intent for an IP prefix in the system, we do not need to create a new one, we only need to update this existing intent by adding more ingress points.

Parameters:

ipPrefix - the IP prefix used to search the existing MultiPointToSinglePointIntent

ingressConnectPoint - the ingress connect point to be added into the exiting intent

mp2pIntentExists

boolean mp2pIntentExists(org.onlab.packet.IpPrefix ipPrefix)

Checks whether there is a MultiPointToSinglePointIntent in memory for a given IP prefix.

Parameters:

ipPrefix - the IP prefix used to search the existing MultiPointToSinglePointIntent

Returns:

true if there is a MultiPointToSinglePointIntent, otherwise false
