SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.

However, with Prince Albert still struggling to find a role for himself there is an inevitable power struggle between husband and wife.Dame Diana Rigg will play the Duchess of Bucchleuch, the young Queen’s new Mistress of the Robes, who is renowned for speaking her mind. She joins returning cast members including Nigel Lindsay (Unforgotten) as Sir Robert Peel, Alex Jennings (The Lady In The Van) as King Leopold, Peter Bowles (To The Manor Born) as Duke of Wellington, David Oakes (The White Queen) as Ernest, Daniela Holtz (Circle Of Life) as Baroness Lehzen and Catherine Flemming (Tatort) as the Duchess of Kent. Below stairs Nell Hudson (Outlander) returns as Skerrett, Ferdinand Kingsley (Borgia) as chef Francatelli and Adrian Schiller (The Secret Agent) as Penge.As well as much drama in Buckingham Palace, the series will include trips to France and Germany, touch on tragedy in Ireland and war in Afghanistan, and see Victoria and Albert discovering sanctuary in the Isle of Wight.The eight-part series and 2 hour Christmas special has been commissioned by ITV’s Head of Drama, Polly Hill and Senior Drama Commissioner Victoria Fea, and will be executive produced by Damien Timmer (Endeavour), Kate McKerrell (Lost In Austen) and Daisy Goodwin for Mammoth Screen. It will again be produced by Paul Frift.Creator, Daisy Goodwin said: “In series one Victoria married the handsome prince, but in this series she and Albert get down to the serious business of living happily, sometimes stormily, ever after. Victoria is the only Queen Regnant to marry and give birth while on the throne and the challenges of being head of state as well as a wife and mother are legion. In many ways Victoria’s dilemma is a modern one - how do you have a successful marriage and a happy family when you are holding down an important job. Can you really have it all?”Executive Producer and Managing Director of Mammoth Screen, Damien Timmer added: “Series one of Victoria was a big success both at home and abroad, and it is a privilege to continue to tell the story of this fascinating woman at a particularly interesting point in her reign. Audiences will be intrigued by the meticulously researched stories Daisy has planned, brimming with scandal, romance and tragedy. At the centre of it is a beautifully nuanced study of a young marriage, and it’s a joy to watch Jenna and Tom find new layers to this iconic couple.”The first series of the drama was ITV’s highest rating drama of 2016, receiving critical acclaim and a consolidated average of 7.7m viewers with a 29% share. It is distributed by ITV Studios Global Entertainment and has been sold in 350 territories worldwide. It has also proved hugely popular in the US, with the first series reaching an average audience of 6.3m viewers and the first episode drawing in a 28% share - more viewers than the first series of Downton Abbey.
