why rstp is faster than stp?

RSTP converges faster because it uses a handshake mechanism based on point-to-point links instead of the timer-based process used by STP. For networks with virtual LANs (VLANs), you can use VLAN Spanning Tree Protocol (VSTP), which takes the paths of each VLAN into account when calculating routes.

Since UDP doesn't have many requirements, it offers a faster connection. TCP, on the other hand, is slower but more reliable. If you need speed more than reliability, you should use UDP instead of TCP. TCP has provisions for data packet sequencing, acknowledgements, error detection, and correction.

6 Answers. Rsync will obviously be faster than scp if the target already contains some of the source files, since rsync only copies the differences. ... Older versions of rsync used rsh rather than ssh as the default transport layer, so a fair comparison would be between rsync and rcp .

rsync is much faster than cp for this, because it will check file sizes and timestamps to see which ones need to be updated, and you can add more refinements. ... You can also use rsync to copy or sync files to a remote machine, or make is run as a daemon. Humble cp can't do such fancy things.

UDP. Faster Speed – UDP VPN service offers significantly greater speeds than TCP. For this reason it is the preferred protocol when streaming HD videos or downloading torrents/p2p . ... Lower Reliability – On rare occasions UDP can be less reliable that TCP VPN connections as UDP does not guarantee the delivery of packets.

For that reason alone, PTP networks have much sharper time resolutions, and unlike NTP, PTP devices will actually timestamp the amount of time that synchronization messages spend in each device, which accounts for device latency.

SFTP runs over an SSH session, usually on TCP port 22. It has been around since late 1990s. The acronym actually stands for "SSH File Transfer Protocol". SCP - a variant of BSD rcp utility that transfers files over SSH session.

Without NAT, IPv6 is faster than IPv4 That's in part because of the proliferation of network-address translation (NAT) by service providers for IPv4 Internet connectivity. ... By contrast, most mobile and broadband subscribers now have native IPv6 on their devices.

Per-VLAN Spanning Tree (PVST+)—PVST+ is a Cisco enhancement of STP that provides a separate 802.1D spanning-tree instance for each VLAN configured in the network. ... Multiple Spanning Tree Protocol (MSTP)—MSTP, defined in IEEE 802.1s, maps multiple VLANs into the same spanning-tree instance.

Answer: As a file transfer protocol, SFTP is secure. SFTP protects the integrity of your files and data by using encryption and it authenticates the server as well as the end user in the transfer. Most FTP clients support SFTP connections.

PSFTP, the PuTTY SFTP client, is a tool for transferring files securely between computers using an SSH connection. ... PSFTP uses the new SFTP protocol, which is a feature of SSH-2 only. (PSCP will also use this protocol if it can, but there is an SSH-1 equivalent it can fall back to if it cannot.)

By nature of the Rapid-PVST protocol being based on RSTP, this also means that Arista switches are backward-compatible with Cisco switches utilizing their proprietary Per-VLAN Spanning Tree Plus (PVST+) protocol.

VLAN Spanning Tree Protocol (VSTP) enables Juniper Networks switches to run one or more Spanning Tree Protocol (STP) or Rapid Spanning Tree Protocol (RSTP) instances for each VLAN on which VSTP is enabled. ... You can configure VSTP for a maximum of 509 VLANs. VSTP and RSTP can be configured at the same time.

RTCP works hand in hand with RTP. RTP does the delivery of the actual data, whereas RTCP is used to send control packets to participants in a call. ... RTP is originated and received on even port numbers, and the associated RTCP communication uses the next higher odd port number.

The following charts show the throughput of the read benchmark for the sequential/warm, sequential/cold, random/warm and random/cold runs. Barring few exceptions, mmap is 2–6 times faster than system calls. Let's analyze what happens in the warm experiments, since there mmap provides a more consistent improvement.

Ultimately, FTP is more efficient at transferring large files, whereas HTTP is better for transferring smaller files such as web pages. Although both utilize TCP as the protocol of choice, HTTP uses a persistent connection, thus making the performance of the TCP better with HTTP than with FTP.
